Audi A4 allroad quattro, 2010

With its permanent all-wheel drive and increased ground clearance, the Audi A4 can handle any road or trail; it also offers driving pleasure - even on unpaved surfaces. Naturally, the Audi A4 allroad quattro features all the innovative technologies which impart to the A4 model line its superiority: a range of powerful and highly energy-efficient engines, Audi drive select (intelligent handling technology), the high-tech S tronic transmission, and innovative communication and assistance systems. The vehicle will be available in early summer at a basic price of 37,100 euros.

The design of the Audi A4 allroad quattro recalls the Audi A4 Avant: crisp lines enclose tastefully curved surfaces and the low roof line establishes a coupé-like silhouette. Striking details re-interpret this model line's sporty elegance. The moon-gray single-frame radiator grille bears vertical chrome strips; an accentuated bumper and large air inlets underscore this vehicle's unique identity. Chrome rings encircle the fog lights. And in the option featuring xenon plus headlights, light-emitting diodes comprise the daytime running lights and taillights. Underneath the front end and tail end, the A4 allroad has a stainless-steel underbody guard.

Interior
Refined touches, uncompromising quality and flawless functionality: the interior of the Audi A4 allroad quattro embodies all the strengths for which Audi is renowned. The cockpit clearly serves the driver. Among the control unit's highlights: the standard electromechanical handbrake - which has replaced the lever on the center console with a button - and the central on-board monitor. A color display complements the concert or symphony sound system, or the MMI navigation system plus; the MMI's offset control unit is housed in the center console.

Customers can choose one of several different trim materials: an exclusive allroad fabric, two types of leather, or an Alcantara/leather combination. The fabric designs are available in two colors and the leather trim in seven colors (two of which feature sporty contrasting stitching). Standard inlays are micrometallic platinum; options include aluminum trigon, natural fine-grain ash, laurel nutmeg, and walnut brown. Carpeting is made of velour; the headlining is star silver, linen beige, or black (optional). Many of the operating controls gleam thanks to their standard aluminum look; the door sill trims bear special allroad logos.

The Engines
Audi will initially offer three different engines for the Audi A4 allroad quattro: a gasoline engine and two diesel engines. All three are turbocharged direct-fuel-injection engines. They command respect due to excellent performance, impressive pulling power, smooth running, and high fuel efficiency. The engines are further bolstered by pioneering technologies arising from Audi's modular efficiency expertise. For example, all three units boast a standard on-board recuperation system, which converts mechanical energy into electrical energy during deceleration.

The Driveline
The 2.0 TDI transmits its power to a six-speed manual transmission. The 3.0 TDI and 2.0 TFSI feature the next generation of Audi's dynamic and very efficient S tronic. This innovative dual-clutch transmission switches extremely smoothly among its seven gears within a few hundredths of a second. S tronic also excels thanks to its high efficiency ratio and a broad spread of the gear ratios. The seven-speed S tronic has a fully automatic mode at the ready: the driver can shift as required, if necessary via shift paddles on the steering wheel.

The differential is in front of the clutch and immediately behind the engine. This technical stroke of genius made it possible to reposition the front axle much closer to the vehicle's front end, in turn allowing for a long wheelbase and an ideal distribution of the axle loads. The benefits include steady straight-line stability, superb ride comfort, and excellent driving dynamics.

The Audi A4 allroad quattro features quattro permanent all-wheel drive as standard equipment. Its purely mechanical center differential favors the rear, distributing power at a 40:60 ratio to the front and rear axle. If necessary, the quattro permanent all-wheel drive can route up to 65 percent to the front or as much as 85 percent toward the tail end.

Audi A1 e-tron Concept, 2010

 

 

Audi A1 e-tron Concept, 2010

The new e-tron model series from Audi will gain another new member at the 2010 Geneva Motor Show: The Audi A1 e-tron Concept is a Mega City Vehicle (MCV) with an innovative drive technology. It comes equipped with a powerful electric motor for zero-emission driving in the city. There is also an internal combustion engine on board that recharges the battery in exceptional circumstances. The Audi A1 e-tron Concept is very agile thanks to the 75 kW (102 hp) peak power of its electric motor.

The technology of the Audi A1 e-tron
The e-tron model family from Audi is just a few months old, but it already has a number of members, for each of which Audi has chosen a different drive technology. The first e-tron, which debuted at the 2009 IAA in Frankfurt/Main, is a near-series high-performance sports car with electric motors for all four wheels. The study shown at the Detroit Motor Show in 2010 is a lightweight, compact two-seater with two electric motors on the rear axle.

The Audi A1 e-tron Concept now presents another approach - a compact electric car in the premium class. The four-passenger, two-door MCV city car was designed specifically for use in the metropolitan areas of Europe and North America and in the rapidly growing megacities of Asia and South America. The Audi A1 e-tron always drives on electric power; its internal combustion engine is only used to recharge the battery in isolated cases.

The integration of the new technologies shows the holistic approach that Audi is pursuing with electric mobility. The objective is to use the energy with the lowest possible losses. The precise interaction of the components, their intelligent packaging, and the efficient management of the current flows are the product of the expertise that the company has developed in this area.

Audi has developed a proprietary thermal management system to keep the battery, the electric motor, and the power electronics within their respective ideal temperature windows.

The electric motor: 75 kW (102 hp) peak power
The synchronous electric motor of the Audi A1 e-tron is mounted transversely at the front of the car. Its low mounting position has a positive effect on the vehicle's center of gravity. Continuous output is rated at 45 kW (61 hp), with peak power of 75 kW (102 hp) available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).

The electric motor sends its power to the front wheels via a single-speed transmission. The elegant, retractable selector lever on the console of the center tunnel used to choose between "Drive," "Reverse," and "Neutral" was taken from the first Audi e-tron.

The power electronics are mounted in the engine compartment above the electric motor. The most important components are the pulse-controlled inverter, which serves as the controller between the electric motor and the battery; the DC converter, which connects the high-voltage network with the 14 volt electrical system; a breaker unit to protect the high-voltage components; and the charging module. The socket for the standard charging plug is located behind the rings in the single-frame grille of the Audi A1 e-tron. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. A display immediately adjacent to the plug-in connection shows the current charge status and the charging time remaining.

The concept of the innovative Mega City Vehicle requires the electrification of key auxiliaries. The refrigerant compressor of the climate control system, for example, is electrically powered by a high-voltage electric motor that supplies only the amount of power needed at the time.

This increases system efficiency substantially compared to conventional concepts. Thanks to a special circuit, the climate control loop also functions as a heat pump that regulates the temperature of the cabin and the battery.

The power steering of the Audi A1 e-tron is electro-mechanical and thus particularly energy-efficient. An electronic brake system makes it possible to tap into the recuperation potential of the electric motors. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire ("brake by wire"). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied. In addition, the servo unit received a new, demand-controlled electric vacuum pump.

Audi e-tron Concept

Audi presents the highlight of the IAA 2009: the Audi e-tron Concept, a high-performance sports car with a purely electric drive system. Four motors - two each at the front and rear axles - drive the wheels, making the concept car a true quattro. Producing 230 kW (313 hp) and 4,500 Nm (3,319.03 lb-ft) of torque, the two-seater accelerates from 0 to 100 km/h (0 - 62.14 mph) in 4.8 seconds, and from 60 to 120 km/h (37.28 - 74.56 mph) in 4.1 seconds. The lithium-ion battery provides a truly useable energy content of 42.4 kilowatt hours to enable a range of approximately 248 kilometers.

The performance figures are by no means the only evidence of the consistent and holistic strategy. The design makes it clear that the Audi e-tron Concept belongs in the major leagues of sports cars, and the package takes into account the specific realities of an electric vehicle. The battery is directly behind the passenger cabin for an optimal center of gravity and axle load distribution.

The Audi e-tron Concept is able to freely distribute the powerful torque of its four electric motors to the wheels as required. This so-called torque vectoring allows for dazzling dynamics and an undreamed-of level of agility and precision when cornering.

Audi has taken a new and in some cases revolutionary approach to many of the technical modules. A heat pump is used to efficiently warm up and heat the interior. The drive system, the power electronics and the battery are controlled by an innovative thermal management system that is a crucial component for achieving the car's range without compromising its high level of interior comfort. Networking the vehicle electronics with the surroundings, which is referred to as car-to-x communication, opens new dimensions for the optimization of efficiency, safety and convenience.
Audi e-tron Concept

The Concept

Electric drive systems are still very much outsiders. The first vehicles of this type took to the roads around 1900, yet in 2009 no volume car manufacturer has a car powered exclusively by batteries in its lineup. Fewer than 1,500 electric vehicles are currently registered in Germany, corresponding to only 0.035 percent of all registered vehicles.

Yet electric driving potentially offers numerous advantages. Electric cars reduce the dependence of transportation and the economy on the raw material petroleum. They produce no direct exhaust emissions and thus ease the local burden on the environment. Electric drive systems are also significantly more efficient than combustion engines, consequently making them easier on the customers' wallets. Other strengths include sportiness and the fun they bring to driving. All of the torque is essentially available the moment the driver steps on the accelerator, allowing for breathtaking acceleration.

There is still a lot of work to do before electric cars are ready for volume production, however. The greatest challenge is the integration of the energy storage system. Acceptable range and performance requires a traction battery that is heavy and takes up a lot of space. Audi is taking a new approach to offset these disadvantages - a holistic approach with a specific vehicle package, a systematic lightweight construction concept and an optimal configuration of all components for the electric drive.

Audi e-tron Concept - The Holistic Approach

The most important development related to batteries for electric drives are lithium-ion cells. Numerous experts throughout the world are working on their further development for use in cars, with the primary objectives being to reduce weight and increase capacity and performance. Audi has also opted for this technology, both for use in a hybrid production vehicle, such as the upcoming Q5 hybrid, and in the e-tron test platform.

The requirement specification for the concept vehicle goes far beyond battery technology and the replacement of the combustion engine with an electric drive system, however. The Audi development engineers decided back in the concept phase to design practically every component and technology based on the new requirements of electric mobility. The interaction of all elements has a decisive influence on the factors efficiency, range and practicality.

The Audi team therefore focused its attention on the total vehicle, which is reflected in the comprehensive requirement specification.

* The reduction of road resistances and the resulting increase in range plays a major role with electric vehicles. Lightweight construction was therefore a top priority for the Audi e-tron Concept car. The body, in particular, combines low weight with supreme strength and rigidity. An intelligent aerodynamics concept with active elements helps to reduce consumption.
* The package ensures the safe integration of the electric drive system and the battery. Placing the battery in front of the rear axle ensures an optimal axle load distribution without compromising the compact overall design and the generous amount of interior space.
* Advanced battery technology enables a practical range. The battery system is water-cooled for optimal performance and service life.
* A needs-based energy management system controls all functions for the chassis, convenience equipment and other auxiliary consumers.
* The innovative thermal management system with optimally matched cooling and heating components considers the cooling requirements of the battery and the drive system in addition to the interior temperature.
* Driving dynamics and road comfort are what Audi customers have come to expect in the sports car segment.
* Vehicle safety is on par with the best of today's production vehicles.
* The driver is provided with clear and comprehensive information.
* The Audi e-tron Concept car uses car-to-x communication technology developed by Audi to improve the efficiency of conventionally powered vehicles. For example, information about traffic light cycle times and the flow of traffic - provided by the infrastructure and other vehicles - is used to compute an optimal driving strategy. Audi has already modeled such a solution in Ingolstadt as part of its "travolution" project.

Design and Package

The caliber of the car is apparent to the observer at first glance. The Audi e-tron Concept has a wide, powerful stance on the road. The car body seems almost monolithic; the closed rear end appears powerful and muscular. The trapeze of the single-frame grille dominates the front end and is flanked by two large air intakes. The top of the grille merges into the flat strips of the adaptive matrix beam headlamp modules with their clear glass covers. High-efficiency LED technology is used for all lighting units - a matter of honor for Audi as the worldwide pioneer in this field.

The headlamps are the core of a fully automatic light assistance system that reacts flexibly to any situation. The new technology recognizes weather conditions and adapts the illumination to rain or fog. The technology at the heart of the light assistance system is a camera that works together with a fast computer to detect oncoming traffic, recognize lanes and measure visibilities, such as in the event of fog.

If there is oncoming traffic, for example, the high beams are turned off in the corresponding section of the illumination field. The cornering light system analyzes data from the navigation system and illuminates corners before the driver steers into them. The Audi e-tron Concept does not have conventional fog lamps that consume additional power. It instead intelligently varies the low beams to widen the illumination field, thus significantly reducing the glare from the car's own lights.

The variability of the headlamps is also reflected in their design. The LED elements change appearance and thus the character of the front end of the vehicle depending on the speed driven and the ambient conditions. The innovative lighting technology offers the Audi designers almost as much design freedom as the shape of the body does.

A new design element unique to the Audi e-tron Concept are the air intakes in the single-frame grille and in front of the rear wheel wells. They are closed flush under normal circumstances and opened by means of flaps when additional cooling air is required. Maximum efficiency is also the reason behind this measure. The concept car has a remarkably low drag coefficient, which gets even better when the flaps are closed.

The vehicle body is compact. The sweeping line of the front end and the flat curved roof immediately identify the two-seater as an Audi. The contours of the flanks are familiar. The tapering of the dynamic line above the sill and the shoulder line tie together the front end, the side and the rear, lend a plastic quality to the doors and the transition to the side air intake and sharply emphasize the Audi-typical round wheel wells with the large, 19-inch tires.

1.90 meters (74.80 in) wide, just 4.26 meters (167.72 in) long and 1.23 meters (48.43 in) tall - those are the proportions of a supercar. The wheelbase of 2.60 meters (102.36 in) leaves plenty of room between the axles for people and technology. Like with a mid-engined sports car, the cabin of the Audi e-tron Concept is shifted far forward toward the front axle, leaving room in front of the rear axle for the roughly 470 kilogram (1036.17 lb) battery unit, the inverter and the power electronics.

The two electric motors, which have their own cooling system, are mounted behind the rear axle. The front electric motors are mounted on the front axle, with their cooling system arranged in front of them. This special package, which features a 42:58 weight distribution, ensures perfect balance, which contributes to the driving dynamics of the Audi e-tron Concept.

Systematic lightweight construction is an even more important prerequisite for efficiency and range with electric vehicles than for conventionally powered automobiles. The Audi development engineers drew on the core competence of the company for the Audi e-tron Concept. The body structure is based on Audi Space Frame (ASF) technology and was realized as a hybrid construction. All add-on parts - doors, covers, sidewalls and roof - are made of a fiber-reinforced plastic.

The combination of aluminum and carbon fiber-reinforced composite material guarantees supreme rigidity coupled with low weight. Audi will soon use this technology in a similar form for production vehicles. Despite the complex drive system layout with four electric motors and a high-capacity battery system, the total weight of the Audi e-tron Concept is only around 1,600 kilograms (3527.40 lb).

Interior and Control Concept

Optical and functional references to the new drive concept characterize the interior design. They establish an advanced connection between proven Audi genes and new formal hallmarks. Typical for the Audi design language is the reduction of the architecture, controls and flow of information to the essential in favor of visible lightweight construction and a tidy overall impression.

The dash appears to float and has a curve that extends laterally into the door panels. With no need to allow for a transmission, shifter and cardan tunnel, the designers took advantage of the opportunity to create a particularly slim and lightweight center tunnel and center console. The flush gear selector, with which the driver chooses between the modes forward, reverse and neutral, emerges from the tunnel when the vehicle is started.

The cockpit of the Audi e-tron Concept is also oriented toward the driver - a further characteristic Audi trait. Instead of the classic instrument cluster, the concept car is the first Audi to be equipped with a large, fold-out central display with integrated MMI functions. It is flanked by two round dials.

The MMI is controlled via a scroll pad with a touch-sensitive surface on the steering wheel ("MMI touch") - an element inspired by modern smartphones.

While an analog speedometer on the right provides speed information, the instrument on the left tells the driver how much power is being drawn. The central display shows the range in the status bar and presents all key information from the infotainment and navigation systems. It also provides the driver with relevant data from the vehicle's communication with its surroundings. The instruments combine the analog and the digital worlds into a single unit.

Characteristic for the concept of the Audi e-tron Concept is the near total elimination of switches and small components such as the ignition. The climate control unit is located to the right above the steering wheel. The display provides temperature and ventilation information. Again drawing inspiration from a smartphone, the system is controlled by means of a touch-sensitive sliding control.

The racing-inspired lightweight bucket seats combine excellent lateral support with comfort. To contrasting colors - snow white and cognac - delineate the various zones of the interior. The colors and the high-quality materials combine elegance and sportiness.

Drive System and Energy Supply

Four asynchronous motors with a total output of 230 kilowatts (313 hp) give the Audi e-tron Concept the performance of a high-output sports car. The concept car can accelerate from 0 to 100 km/h (0 - 62.14 mph) in 4.8 seconds if necessary, and goes from 60 to 120 km/h (37.28 - 74.56 mph) in 4.1 seconds. The torque flows selectively to the wheels based on the driving situation and the condition of the road surface, resulting in outstanding traction and handling.

The top speed is limited to 200 km/h (124.27 mph), as the amount of energy required by the electric motors increases disproportionately to speed. The range in the NECD combined cycle is approximately 248 kilometers (154 miles). This good value is made possible by the integrated concept: technology specially configured for the electric drive system combined with state-of-the-art battery technology. The battery block has a total energy content of roughly 53 kilowatt hours, with the usable portion thereof restricted to 42.4 kWh in the interest of service life. Audi uses liquid cooling for the batteries.

The energy storage unit is charged with household current (230 volts, 16 amperes) via a cable and a plug. The socket is behind a cover at the back of the car. With the battery fully discharged, the charging time is between 6 and 8 hours. A high voltage (400 volts, 63 amperes) reduces this to just around 2.5 hours. The Audi engineers are working on a wireless solution to make charging more convenient. The inductive charging station, which can be placed in the garage at home or also in special parking garages, is activated automatically when the vehicle is docked. Such technology is already used today in a similar form to charge electric toothbrushes.

The battery is charged not only when the car is stationary, but also when it is in motion. The keyword here is recuperation. This form of energy recovery and return to the battery is already available today in a number of Audi production models. During braking, the alternator converts the kinetic energy into electrical energy, which it then feeds into the onboard electrical system.

The Audi e-tron Concept, which is slowed by four lightweight ceramic brake discs, takes the next large step into the future. An electronic brake system makes it possible to tap into the recuperation potential of the electric motors. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire ("brake by wire"). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied.

This decoupling of the brake pedal enables the Audi e-tron Concept's electric motors to convert all of the braking energy into electricity and recover it. The electromechanical brake system is only activated if greater deceleration is required. These control actions are unnoticeable to the driver, who feels only a predictable and constant pedal feel as with a hydraulic brake system.

Making its Automotive Debut: The Heat Pump

The heat pump - used here for the first time ever in an automobile - also serves to increase efficiency and range. Unlike a combustion engine, the electric drive system may not produce enough waste heat under all operating conditions to effectively heat the interior. Other electric vehicles are equipped with electric supplemental heaters, which consume a relatively large amount of energy. The heat pump used by Audi - and commonly used in buildings - is a highly efficient machine that uses mechanical work to provide heat with a minimum input of energy.

A high-efficiency climate control system is used to cool the interior. It works together with the thermal management system to also control the temperature of the high-voltage battery. The battery, the power electronics and the electric motors must be kept at their respective ideal operating temperatures to achieve optimal performance and range.

As soon as the vehicle is connected to a charging station the vehicle is preconditioned as appropriate by the thermal management and other associated systems.

The drive system is heated if temperatures are cool, and cooled if hot. This preconditioning can also be extended to the interior, if necessary, so that the passengers can step into a cabin that has been heated or cooled as appropriate for their comfort.

Driving Dynamics

The normal distribution of the tractive power is clearly biased toward the rear axle in accordance with the weight distribution of the Audi e-tron Concept. Similarly to a mid-engined sports car, roughly 70 percent of the power goes the rear and 30 percent to the front. If an axle slips, this balance can be varied by means of the four centrally controlled electric motors. The electric vehicle from Audi thus enjoys all of the advantages of quattro technology.

The four individual motors, which in the interest of greater traction are installed behind the wheels as wheel drives, also enable the Audi e-tron Concept's lateral dynamics to be intelligently controlled. Similar to what the sport differential does in conventional quattro vehicles, torque vectoring - the targeted acceleration of individual wheels - makes the Audi e-tron Concept even more dynamic while simultaneously enhancing driving safety. Understeer and oversteer can be corrected by not only targeted activation of the brakes, but also by precise increases in power lasting just a few milliseconds. The concept car remains extremely neutral even under great lateral acceleration and hustles through corners as if on the proverbial rails.

The chassis has triangular double wishbones at the front axle and trapezoidal wishbones made of forged aluminum components at the rear axle - a geometry that has proven in motorsports to be the optimal prerequisite for high agility, uncompromising precision and precisely defined self-steering behavior. A taut setup was chosen for the springs and shock absorbers, but it is still very comfortable.

The direct rack-and-pinion steering gives finely differentiated feedback. Its electromechanical steering boost varies with speed, so that the Audi e-tron Concept only has to provide energy while steering, and not while driving straight ahead.

As befitting its status, the Audi concept car rolls on 19-inch tires with a new blade design. 235/35 tires up front and 295/30 tires in the rear provide the necessary grip.

Car-to-x Communication

The electronics development engineers at Audi not only aimed to make the Audi e-tron Concept as efficient and fun to drive as possible, they were also very concerned with safety and traffic management. The technical concept car includes a prototype of an information processing system. Future generations of these systems will usher in a new era in the networking of road traffic, particularly in regions and countries with a high volume of traffic. This progress is made possible by the rapid advancements in computing power, software and communication technology.

The buzzword "car-to-x communication" refers to the direct exchange of information in flowing traffic and to the traffic environment. The letter "x" is a free variable that can refer just as easily to other vehicles as to fixed infrastructure such as traffic lights. In contrast to today's telematic systems, car-to-x communication no longer requires a central service provider to quickly and effectively pool and process information. The participants themselves perform these tasks by spontaneously networking with one another.

The future car-to-x network still needs some time before it becomes reality on the roads. This obstacle is one that can be overcome, however, as nearly every carmaker in Europe, the U.S.A. and Japan has decided to develop a common standard for hardware and software. Once all new cars are equipped with this technology, a functional network of automotive transmitters will soon be available, at least in large population centers.

These transmitters can be used to open up many new practical applications. Below are just four examples showing the possibilities offered by car-to-x communication.

Example 1 - Efficiency and range: Numerous external factors influence energy consumption and thus the range of any vehicle. An intelligent vehicle equipped with car-to-x technology is aware of necessary braking or acceleration maneuvers in advance because it combines navigational data with information about the flow of traffic, for example. The central computer can prevent driver actions that would use energy unnecessarily or use targeted braking for recuperation of the battery.

Example 2 - Safety: A vehicle has spun out on a slippery road in a blind curve and is unable to free itself under its own power. At the same time, other vehicles are approaching quickly. The stuck vehicle uses car-to-x to send out a warning signal reporting the precise location of the hazardous location. A corresponding warning then appears on the navigation system display of the approaching cars.

Example 3 - Traffic flow: Many cars are traveling between traffic lights on an arterial road. Over and over again, they accelerate only to have to brake again when the traffic light changes to red. Car-to-x technology enables them to establish a network between themselves and receive information from the traffic light controller. The drivers can then make more judicious use of the gas pedal because they know what to expect. The same applies for imminent traffic jams: cars ahead provide information that results in adjustments to the posted speed limits, noticeably spreading out the traffic.

Example 4 - Convenience: The driver has entered a shopping center with a chronic shortage of parking spaces into his navigation system as the destination. With car-to-x, the mobile system networks with the parking space registration system at the destination. When the system in the parking garage reports that a convenient parking spot is available, the navigation system can register its location and also reserve the spot.

ABT Audi R8

The Abt R8: Sports car in perfection

There are cars and dream cars. The latter includes Lamborghini's Gallardo, Ferrari's F430 or Porsche's 911 Turbo. These cars make your heart beat faster and show the perfected magic of speed on the roads. Abt Sportsline's R8 will also be among these outstanding super sports cars and is getting ready to overtake them in the prestige duel.

The design studies already show the first impressions of Abt's sportiest creation - and prove that the Kempten-based tuner manages to perfect an excellent serial model like the R8 to detail and accentuate its racing genes already in the drawing. The front of the Bavarian R8 shows the marked Abt face. Together with the unique and beautiful rear with its four inclined arranged exhaust end pipes, the rear diffuser and the extravagant rear wing, the front of the Abt R8 is part of an overall concept that brings about phenomenal roadholding. The add-on parts of the super sports cars from the Allgäu-region improve downforce and ensure perfect balance of the front and rear axis. This is especially notable in speed ranges reserved for only a few cars. The sideblades which were developed especially for the Abt R8 and the Abt side skirts give the Abt R8 a new and individual design besides aerodynamical advantages. The aerodynamically efficient Abt body kit, which also includes carbon-fibre parts, is a real eye catcher but also shows the state-of-the-art Bavarian precision work. With the ingenious construction, which also includes a carbon-fibre bonnet, not only a maximum reduction in weight is achieved but it also ensures optimized weight distribution of the Abt R8 - the pure presence of the model athlete already shows this.

The technology and the design milestones do not only come from Maranello or Sant'Agata-Bolognese but also from Kempten. The Abt R8 will be a gorgeous dream car with the genes of a top-class race car. This special automobile will belong to one of the fastest among the fastest; the Abt R8 will also challenge the Lamborghinis and Porsches. With regards to the anticipated performance data the Bavarians are traditionally discreet. But this data already amazes sports car fans and makes them want to spur the hot-blooded Bavarian horses. 530 HP (390 kW) are to be drawn from the 4.2 litre-V8 thanks to the Abt supercharger. Compared with the serial model which already shows impressive performance data this means an increase of 110 HP (81 kW). The brand new Abt 20-inch BR wheels stylishly transfer this power onto the asphalt. The all-wheel-drive dream car accelerates from 0 to 100 km/h in just 3.9 seconds and reaches a top speed of 317 km/h. These values are synonymous with magic and this extraordinary super sports car desperately wants to be driven. By means of the Abt suspension which is adjustable in height, pressure and rebound, the performance and driving comfort of the super sports car can be adapted perfectly to the requirements of its driver.

The top-of-the-line model of Audi's new family of convertibles is the Audi S5 Cabriolet. The engine of the S5 Cabriolet is the newly developed, supercharged three-liter V6 with gasoline direct injection. Prices start at EUR 37,300 for the 1.8 TFSI with 118 kW (160 hp) and six-speed manual transmission. Delivery of the first Audi A5 Cabriolet models will begin in the second quarter of 2009.Like all open-top Audi models, the new Audi A5 Cabriolet too has a classic fabric top - which endows it with a striking silhouette of dynamic elegance. The lightweight softtop opens in 15 seconds - and closes in 17 seconds. The fully automatic open/close drive comes as standard. An acoustic top is optionally available, which reduces wind noise almost to the hardtop level.

When opened, the Audi A5 Cabriolet top folds down so effectively that very little trunk space is used up - leaving 320 liters (11.3 cu ft) of unused storage volume, clearly the best value in its field of competitors. The softtop compartment lowers itself automatically when the top is opened.
Equally useful is the fold-down rear seat backrest with the large pass-through between the luggage space and the interior, which increases the storage volume to a generous 750 liters (26.49 cu. ft.).
Automatic seat belt extenders round out the comfort in the interior. Neck-level heating is optionally available for the front seats. The optional leather seats are coated with a special layer to reduce solar heating. There is comfortable room for four persons. The refined ambiance combines with exemplary ergonomics to convey an atmosphere of sporty elegance. Ultra-high-strength steels and selective reinforcements of the body ensure maximal rigidity and crash safety.

The Audi A5 Cabriolet is being launched with three gasoline engines and two diesel engines, with power outputs ranging from 132 kW (180 hp) to 195 kW (265 hp). All five powerplants are fueled via direct injection; four of them use turbocharging. Available power trains include a six-speed manual transmission, the continuously variable multitronic, and the lightning-fast, seven-speed S tronic.

In addition to front-wheel drive, Audi also offers quattro permanent all-wheel drive for the higher-power engines. The innovative sport differential, which variably distributes the propulsive power between the rear wheels, is optionally available to make quattro even more dynamic and even safer.
Fascinating dynamics: Audi drive selectThe perfect addition to this technology package is the Audi drive select vehicle dynamics system, which enables the driver to chose among three different engine maps controlling the characteristics of the fuel feed, the shifting points of the seven-speed S tronic and multitronic, and the mode of operation of the servotronic steering system. If the MMI operating system is installed, a fourth, freely programmable level is also available.

Audi drive select is only available in combination with one or more of three additional technologies - the sport differential, the adaptive control for the shock absorbers, and dynamic steering. This is an additional high-tech solution: Its superposition gear varies the gear ratio as a function of the driving speed by up to 100 percent.The new Audi A5 Cabriolet features a rich array of equipment, including 17-inch alloy wheels, automatic air conditioning, and an audio system with a CD player. One of the highlights among the optional equipment is the third-generation MMI operating system, which provides many attractive navigation and entertainment functions.

As the dynamic top-of-the-line model of the new production series, the Audi S5 Cabriolet occupies a very special position. Its three-liter TFSI - a V6 with turbocharger - unfolds its 245 kW (333 hp) and 440 Nm (324.53 lb-ft) of torque impressively: It responds tenaciously to the throttle and delivers excellent driving performance. The quattro drive, a sport suspension with 18-inch wheels and a number of special equipment details underscore the athletic power of the Audi S5 Cabriolet.

The exterior designThe Audi A5 Cabriolet combines Audi's progressive styling with the fascination of an open-top car. The long engine hood, the sharp lines, the sweep of the shoulder contour, the elegantly curved surfaces, the large wheels, the distinctive front end, and the expressive tail all interact to create a sculptural, sensuous whole. The Audi A5 Cabriolet is 4.63 meters (15.19 ft) long and 1.85 meters (6.07 ft) wide, but only 1.38 meters (4.53 ft) tall: the sportiest proportions in its class.The styling of the front end is dominated by the single-frame grille, which is flanked by large air intakes. The exquisite design of the headlights makes them look like technical jewels. The daytime running lights of the optional xenon plus headlights consist of LEDs. An aluminum molding lends high gloss to the windshield frame.The looks of the tail end are sharpened by horizontal lines, broad tail lights, straight tailpipes, and a distinctly colored diffuser insert. The trunk lid bears an unobtrusive spoiler lip. The xenon plus headlight option comes complete with LED taillights, which create a distinctive light pattern.
The convertible topThe fabric top with the large glass rear window fits smoothly into the design profile. This is one of several reasons why Audi preferred it to a folding steel roof. What's more, its construction is much lighter in weight, which reduces the overall weight of the Cabriolet and lowers its center of gravity. The outer skin of the top is available in a choice of four colors, the inside in three.The softtop consists of three layers. The intermediate layer is a cushioning pad. In the optional acoustic top, which reduces wind noise almost to hardtop level, this is replaced by a foam layer up to 15 millimeters (0.59 in) in thickness. The acoustic top comes with a ceiling light for the rear seat - a solution usually only found in the topmost convertible luxury segment.In both versions, a hydraulic pump and four operating cylinders that move the top are actuated when a pushbutton on the central console or on the optional remote access assistant is depressed. It takes 15 seconds to open the top, 17 seconds to close it. Both actions can also be actuated while driving at up to 50 km/h (31.07 mph) - which makes driving much more comfortable.

When opened, the top is retracted underneath a fixed cover, where it is folded down into an extremely compact shape. Its storage compartment, which automatically lowers itself into the trunk space, only takes up a few centimeters in height - and only 60 liters (2.12 cu ft) of the 380 liters (13.42 cu ft) of luggage space. The remaining 320 liters (11.3 cu ft) with the top open are by far the best value among comparable vehicles. What's more, the low position of the loading lip makes loading and unloading easier. The wind deflector, which is supplied as standard, can be stored in the spare-wheel well to save space.A very convenient feature in the Audi A5 Cabriolet are the split folding rear seat backrests. They can be easily unlocked by actuating levers in the trunk and drop automatically onto the seat cushions. The standard pass-though is 70 centimeters (27.56 in) wide. The loading space behind the front seatback is 1.76 meters (69.29 in) long, providing a total storage volume of 750 liters (26.49 cu ft).

The bodyAs is typical of Audi models, the A5 Cabriolet has an extremely rigid body. This is a prime reason for its precise driving performance, its high comfort level, and its maximized crash safety.In the construction of the body-in-white, several innovative technologies are used. A prime example are the ultra-high-strength steels with their extremely high tensile strength, which Audi manufactures in-house using hot forming. The front fenders of the Audi A5 Cabriolet are made of aluminum to lower the weight and to optimize axle load distribution. An enclosed underbody improves the airflow and thereby the fuel efficiency.A whole array of additional reinforcement parts compensates for the absence of a solid roof. They are located in the front section, in the side skirts, in the windshield frame, and in the rear section. Located between the interior and the luggage section is the rollover protection. When a rollover threatens, spring-loaded aluminum braces are raised behind the rear seat headrests. Door-mounted head and chest sidebags provide protection in the event of a lateral impact.

The interiorWith its generous wheelbase of 2.75 meters (9.02 ft) and the longest interior in its class, the Audi A5 Cabriolet has plenty of room for longer trips. That's also true for the rear seats, which can be optionally divided by a center console with two cup holders.Elegance in flowing lines, functional ergonomics, and top-quality craftsmanship are the principal characteristics of the interior - and this too is typically Audi. The teardrop-shaped settings of the instruments have already become modern classics. The centrally mounted onboard monitor is standard equipment. The formed-plastic console focuses on the driver. Flowing lines link it to the central tunnel and the door linings. If the customer has ordered either one of the two navigation systems it comes with the highly convenient MMI operating system - the best solution on the market.The low standard seats provide excellent control and support. Using seatbelts is facilitated by electric seat belt extenders. Special solutions are available as alternatives: firm sport seats, electric seat adjustment and heating - as a separate option also for the back seats.In the climate-controlled comfort seats, small fans and an automatic auxiliary heater ensure luxurious comfort. This option provides neck-level heating - ducts on the topside of the seatback emit warm air that keeps the back of the head and neck warm. With its three-level control, the headroom heater is also available for sport seats. It prolongs the open-air season in the Audi A5 Cabriolet.Another special feature is provided in the optional leather upholstery: a special coating inhibits solar heating while the Cabriolet is parked in the sun with the top down. This coating reflects infrared radiation and thus lowers the surface temperature by up to 20 degrees Celsius. Audi offers a choice of several seat coverings up to and including Fine Nappa leather. Inlays come as standard in Micrometallic platinum; aluminum and three different kinds of wood are available as options.
The enginesIn the propulsion system of the A5 Cabriolet too Audi has consistently relied on innovative technologies: All five engines - the two TDIs and the three gasoline engines - use direct injection. They are impressive evidence that, at Audi, efficiency and dynamics go together and are interdependent.The most powerful gasoline engine in the Audi A5 Cabriolet is the 3.2-liter FSI. It operates with the innovative Audi valvelift system, which varies the lift of the intake valves in two stages. As a result, the gas exchange improves and the throttle can be left open more often, minimizing throttling losses - which in turn boosts the torque and the power output while reducing fuel consumption. The V6 delivers up to 195 kW (265 hp) as well as 330 Nm (243.4 lb-ft) between 3,000 and 5,000 rpm. With front-wheel drive and multitronic it accelerates the Audi A5 Cabriolet in 6.9 seconds to 100 km/h (62.14 mph) - and up to a top speed of 246 km/h (152.86 mph). Its average fuel efficiency is an impressive 8.6 liters/100 km (27.35 US mpg). An optional alternative is quattro all-wheel drive, combined with the new seven-speed S tronic.The 2.0 TFSI likewise attests to Audi's leadership position in engine design. This four-cylinder engine also uses the Audi valvelift system - but here it acts on the exhaust valves, with similar advantages as in the V6. Audi sells the two-liter turbo in two versions. In the entry-level version, which comes with front-wheel drive and multitronic, it delivers up to 132 kW (180 hp) and 320 Nm (236.02 lb-ft) from 1,500 to 3,900 rpm. This version completes the standard sprint in 8.9 seconds and has a top speed of 219 km/h (136.08 mph). Average fuel efficiency is an excellent 7.4 liters per 100 km (31.79 US mpg).The more powerful version of the 2.0 TFSI delivers 155 kW (211 hp) as well as 350 Nm (258.15 lb-ft) between 1,500 and 4,200 rpm. It is available with three powertrain versions: with the quattro drive package and the seven-speed S tronic, and with front-wheel drive and either multitronic or manual transmission. In the latter version the Audi A5 Cabriolet reaches 100 km/h (62.14 mph) in 7.5 seconds and has a top speed of 241 km/h (149.75 mph). Its average fuel efficiency is an impressive 6.8 liters per 100 km (34.59 US mpg).The two V6 TDIs also set the standards in their class. With their enormous torque and consistent running smoothness they represent the leading-edge sportiness of Audi TDI technology. The three-liter engine generates 176 kW (240 hp) and applies 500 Nm (368.78 lb-ft) of torque to the crankshaft between 1,500 and 3,000 rpm. The sprint from zero to 100 km/h (62.14 mph) takes 6.4 seconds. Top speed is 247 km/h (153.48 mph). This top-of-the-line diesel, which powers all four wheels via the seven-speed S tronic, is content with an impressive average of 6.8 liters/100 km (34.59 US mpg).The second TDI in the program is even thriftier. The 2.7-liter powerplant with 140 kW (190 hp) and 400 Nm (295.02 lb-ft) between 1,400 and 3,500 rpm consumes a mere 6.3 liters/100 km (37.34 US mpg). The smaller V6 diesel comes with front-wheel drive and manual transmission. It goes from zero to 100 km/h (62.14 mph) in 8.6 seconds; 230 km/h (142.92 mph) is its top speed (preliminary values).
The transmissionAudi provides a choice of three different transmissions for the Audi A5 Cabriolet. The 2.0 TFSI with 155 kW (211 hp) comes with a six-speed manual transmission as standard, which excels in its short shifting travels and high operating precision. Both the two-liter engine and the 3.2 FSI are available with the multitronic continuously variable automatic transmission as an option, which combines smooth operation with high efficiency and a fuel-saving transmission ratio. For a dynamic driving style the multitronic is available with a sport program and a manual mode with eight fixed speeds.For the more powerful version of the 2.0 TFSI and for the 3.2 FSI, the seven-speed S tronic is available as an option; in the 3.0 TDI it is standard equipment. This new high-tech dual-clutch transmission changes gears in a few hundredths of a second, and so smoothly that the driver hardly notices it. What's more, it is highly efficient and fuel-saving. The driver can let the seven-speed S tronic shift automatically or interact, if desired, via rocker switches on the steering wheel.The seven-speed S tronic has been designed for use with the quattro permanent all-wheel drive. It is optionally available for the high-end diesel series and for the two powerful gasoline engines. The quattro drive system is dynamically designed - during normal driving it distributes the forces in a 40:60 ratio between the front and the rear. If one wheel skids, a center differential that operates purely mechanically transfers most of the power to the axle with the better traction.
The new sport differential makes the driving dynamics of the quattro drive even more fascinating. This innovative control system steplessly distributes the propulsive torques among the rear wheels depending on the driving situation.This form of torque control makes the steering response of the Audi A5 Cabriolet even more spontaneous and direct and further improves the vehicle's stability. Transverse acceleration is further improved while understeering or oversteering is completely prevented.
The chassisThe Audi A5 Cabriolet leads its class in all relevant sporty criteria - steering response, stability and agility - yet it provides a very smooth ride. The reason for these strengths is the perfect distribution of axle loads. The front axle is located far forward in the front section - a configuration made possible by an unusual solution: the differential is mounted in front of the clutch or torque converter.The chassis design too is technologically advanced: The front wheels are mounted on a five-link axle. The front axle support is firmly bolted to the body in order to maximize rigidity. The steering forces are transmitted to the wheels directly via the steering box, which is mounted very low within the chassis. The hydraulic rack-and-pinion steering provides a very responsive and highly precise connection to the road. Optionally available is the servotronic, which adjusts its support level to the driving speed.The rear-wheel suspension of the Audi A5 Cabriolet is supported by a trapezoidal-link axle, which combines a smooth ride and maximum driving stability. The essential parts of both the front and the rear suspension are made of aluminum. The large brakes ensure powerful deceleration and react very precisely to the degree of pedal pressure. 16-inch or 17-inch aluminum wheels are standard, depending on the engine version. Optionally available from Audi and quattro GmbH are 18-, 19- and 20-inch wheels.Another high-tech feature in the new Audi A5 Cabriolet is the Audi drive select vehicle dynamics system. It influences the characteristics of the fuel feed, the speed change points of the seven-speed S tronic, and the operating mode of the servotronic steering system. The driver presses a key to select a comfortable, intermediate, or dynamic operating mode for these subsystems. If the vehicle is equipped with a navigation system - and the MMI operator control that comes with it - a fourth engine map is provided, which the driver can program to suit.Audi drive select is only available in combination with one or more of three additional technologies - the differential, the adaptive shock absorber control, and dynamic steering. Its superposition gear varies the gear ratio by nearly 100 percent as a function of the driving speed. The dynamic steering operates directly in city traffic. In highway driving it uses a more indirect ratio. To maximize driving safety, it cooperates closely with the ESP stabilization program - at the handling limits it keeps the Audi A5 Cabriolet on course by lightning-fast small interactions.

The equipment
The Audi A5 Cabriolet comes with an impressive array of standard equipment. This includes a fully automatic convertible top, 16-inch or 17-inch alloy wheels, a fold-down rear seatback with a large pass-through, and automatic air conditioning; the chorus audio system comes with integral CD player. Electric seat belt extenders and an electromagnetic parking brake are also standard.Further luxury is available in the options: The adaptive light option combines xenon plus headlights with dynamic cornering lights; the high-beam assistant changes automatically between low beam and high beam. The advanced key provides keyless access and allows starting the car as well as opening and closing the top remotely. The deluxe automatic air conditioning manages the temperature separately in three zones in the vehicle. The acoustic top further lowers the wind noise level. And the climate-controlled comfort seat in combination with the neck-level heating creates a perfectly tempered environment.When it comes to the chassis, the program is complemented by the Audi drive select system, the sport differential, and two conventional sport suspensions. The S line sport package plus combines the stiff set-up with performance features such as 10 millimeters less body height, 18-inch wheels and 245/40 tires with a package of special details for the interior. The S line exterior package, on the other hand, endows the vehicle with an especially dynamic look.Further highlights are the two infotainment systems MMI navigation and MMI navigation plus - members of an entirely new equipment generation. Even the lesser model includes navigation imaging featuring 3D color graphics, a versatile reader for memory cards, and a DVD drive. Optionally available from Audi is a module for digital radio reception, a Bluetooth interface for the mobile phone, and an interface for full integration of the iPod.

The top version comes with exclusive technologies: an especially high-definition monitor, a big hard drive for music files and addresses, plus a special joystick function for the MMI control unit. With refinements such as a Bang & Olufsen sound system or a digital TV tuner, the MMI navigation plus can be turned into a high-end media center.Innovative assistant systems from the luxury class make driving in the Audi A5 Cabriolet even more supremely relaxed. Audi optionally equips its open-top four-seater with high-tech solutions including adaptive cruise control, Audi side assist and Audi lane assist. They control the distance from the vehicle in front and assist in staying in lane or in changing lanes. The luxury-class Audi parking system advanced uses a rearview camera to display the area behind the vehicle on the onboard monito

Audi : RSQ Concept

The Audi RSQ is a mid-engined concept car developed for use as a product placement in the 2004 sci-fi movie I Robot. It is meant to depict a technologically advanced automobile from the year 2035.

This sports coupé is a visionary interpretation of Audi's typical automobile design. An important challenge presented to the designers was that despite its extreme character the car still had to be recognized by the audience as an Audi. To accommodate this demand, the engineers implemented a current Audi front-end design that includes a single-frame grille and the company's trademark overlapping rings.

The RSQ also includes special features suggested by movie director Alex Proyas. It utilizes spheres instead of wheels and its two butterfly doors are hinged to the C-posts of the body.
Although this kind of collaboration was a first for Audi, a similar project was developed by Lexus for use in the 2002 film Minority Report.
