Lotus : Hot Wheels Concept

Group Lotus plc has teamed up with Hot Wheels®, the famous global die-cast brand, to design, develop and produce a Lotus Hot Wheels® Concept vehicle. This 1:5 scale model was on display to the world at the annual SEMA Show at the Las Vegas Convention Centre between 29th October and 2nd November 2007, and a 1:64 scale version of the design will become part of the Hot Wheels® product range in spring 2008.

To celebrate its 40th anniversary next year, Hot Wheels® approached Lotus and other world leaders in he automotive industry with the challenge for each company to produce a vehicle that embodies its own engineering philosophy and brand. The result from Lotus is a stunning open-top two seat sports car concept. Russell Carr, Head of Lotus Design said; "This was a dream job for the design team because, for many of us, when we were children, it was Hot Wheels® that first ignited our passion for cars and design.

Lotus Design's international reputation for designing visually dynamic and exhilarating sports cars perfectly fitted the brief for this programme and we relished the opportunity to design a concept that was free from the typical technical and legal constraints of a full size car. In addition the design offered unique challenges because it has to work as a toy and we therefore had to remember how specific views, features and tactile qualities of toy cars fascinated us as children. I am very proud of the final design by Steven Crijns that succeeds in being both instantly recognisable as a Lotus and a Hot Wheels® Car. Steven Crijns, Design Manager at Lotus Design and creator of this concept design explained; "Hot Wheels® cars are barely 75mm long, so specific attention went to create a bold shape that would work well at this scale. Another challenge was to create an exciting design that would work well as a toy. The car needed to be recognisable as a Lotus without having to turn it over to look at the badge underneath, so I took elements from the Lotus Elise and Lotus Exige such as the headlight design, the Lotus 'mouth', the pronounced wheel arches and trademark bonnet graphics. I was keen for the design to express the Lotus philosophy of performance through lightweight: the shrink wrapped body is kept to an absolute minimum to save weight. The dynamic voluptuous curves make the car look agile and fun to drive. Bold aerodynamic aids are incorporated to achieve exceptional Lotus handling. The top exit radiator at the front, a distinctive Lotus design feature, the rear diffuser and a large rear wing all provide down-force helping the vehicle stick to the road. In addition, large side air intakes and an open rear end aid engine breathing. Inside the car, the exposed centre spine is part of the structure and incorporates the switches and gear linkage and supports the rear wing."

Mike Kimberley, Chief Executive Officer of Group Lotus Plc said "We are delighted to have worked with Hot Wheels®, who share our passion and enthusiasm for all things automotive. Lotus Design has a global reputation and is responsible for the design of all Lotus cars, including Lotus Europa, Exige and iconic Elise and many designs for our engineering clients globally. The same design team who created this stunning concept is also designing our new range of cars, the first of which, codenamed Project Eagle, will go into production at the end of next year."








Chrysler : ecoVoyager Concept


Chrysler's concept for 2008 - the ecoVoyager - marries an elegant American design with fuel cell Range-extended Electric Vehicle technology.
"The 2008 Chrysler ecoVoyager concept vehicle celebrates the romance of automobile travel embodied in a four-door, four-passenger, distinctively American automobile of spirited design," said Greg Howell, principal ecoVoyager concept exterior designer. "While the ecoVoyager's supple, flowing one-box shape is purposely designed to achieve aerodynamic efficiencies, it also pushes the Chrysler brand language in a new direction of 'elegant simplicity,' by taking full advantage of the space normally occupied by a bulky conventional powertrain setup to drastically reduce the front overhang."

Featuring crisscrossing forms defined by hard lines with fluid intersections, the style vocabulary of the ecoVoyager embodies Chrysler's harmonisation of functional technology with beautifully-styled exteriors and interiors.
The Chrysler ecoVoyager concept was developed for customers wanting a travel experience on par with a private jet, but without a lot of fancy gadgetry. These customers seek three critical attributes: elegance, simplicity and serenity.

Chrysler ecoVoyager Concept Technology
The all-new Chrysler ecoVoyager's wheels are driven by an electric motor, with power primarily supplied by a lithium-ion battery pack capable of satisfying a consumer's typical daily commute of less than 40 miles.
The electric motor develops 200 kilowatts (268 horsepower), enabling acceleration from 0 to 60 mph in less than eight seconds. A regenerative braking system captures energy that would normally be lost and returns it to the battery, making the Chrysler ecoVoyager concept a very efficient and spacious vehicle.

The ecoVoyager takes advantage of a range extender - in this case, a small, advanced hydrogen fuel cell -- to extend the vehicle range for occasional long trips. With this advanced technology, the Chrysler ecoVoyager's total range is greater than 300 miles, while no emissions - besides water vapour -- come from the tailpipe along the way.
With the entire propulsion system located below the ecoVoyager's floor, space is maximized for utility of passenger and cargo.

Chrysler ecoVoyager Concept Exterior
Expressive details of the Chrysler ecoVoyager concept include panoramic roof glass bisected by a centre spine, tight body overhangs and a dramatic boat-tail back end. The sinuous shapes of the window graphics, headlamps, tail lamps and grille openings are inspired by Chrysler's storied winged badge.
The curving trapezoidal shape of the ecoVoyager's grille is echoed by the clear lens-covered shadow box that houses the rear license plate. The sloping backlight features a similar shape, emphasizing the repeating harmony of the ecoVoyager's design elements.

Other exterior touches on the Chrysler ecoVoyager concept include the elongated, flaring "light catchers" on the lower doors and the front and rear fascias, enhanced by the Polar Ice exterior colour.
Finally, side doors open a wide 90 degrees. Since the rear doors are hinged at the rear and there is no centre B-pillar, entrance into the ecoVoyager is virtually unimpeded.

Chrysler ecoVoyager Concept Interior
By placing the front wheels of the Chrysler ecoVoyager concept farther forward than usual, designers were able to create greater interior roominess and increased legroom, especially in the rear seats.
In the ecoVoyager's spacious interior, the size, design and location of all controls have been rethought to provide its four pampered passengers the luxury of having every feature within effortless reach.

"In some ways, true luxury is in not having to reach or search around for controls," said Ty Stump, principal interior designer of the Chrysler ecoVoyager concept. "With the new ecoVoyager concept, we carefully placed the gauges and controls in order to reduce head and eye movement. We also achieved simplicity in the interior forms, both for visual elegance and to avoid distracting surfaces."
The ecoVoyager's windshield defroster and cabin air-conditioning outlets in the instrument panels and doors, for example, are invisible beneath a recessed perforated mesh. This avoids visually-disruptive array sliding vanes and protruding knobs. Even the colour of the interior -- soft Dove Gray with warm cherry wood accents — is designed to promote a relaxed ambiance.

The Chrysler ecoVoyager's unconventional instrument panel features a broad, leather-covered angled surface, slightly V-shaped in plan view and fronted by a full-width display screen set just below the windshield. The left and right outer ends of this non-glare screen contain the side-view mirror image, while a third camera image in front of the driver serves as the rear-view mirror.

Unlike most instrument clusters, only currently-needed information is displayed, designed to be viewed above the steering wheel rim rather than through it (and requiring less up-down eye movement and refocusing). The front-seat passenger can view a movie without its moving images disturbing the driver. A slick, slide-out/retractable centre console - fitted with hot-key buttons and a mouse pad - replaces the functions contained in a conventional vertical centre stack.
The ecoVoyager's four individual chairs are contoured for personalised comfort. The seat framing is exposed, with under-seat storage drawers. Front seats have individual cantilevered, adjustable armrests containing the window controls and heat/massage switches, while individual rear-seat armrests fold into the cabin back panel. With the ability to store six 20-ounce bottles, the floor console dividing the rear seats accommodates hot or cold beverages.

A recessed area in the headliner between the two longitudinal skylights contains the "Direct Sound" function. With this feature, the musical entertainment choice of each individual occupant can be directed to him or her without the use of headphones, and without disturbing others in the car.
Sleek, refined, efficient and superbly comfortable, the Chrysler ecoVoyager concept vehicle offers a new experience in stress-free travel.

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.

Lotus : Ice Vehicle Concept





Peugeot HYmotion3: Compressor Concept

The occupying a half-way house between the world of the scooter and the car, the Peugeot HYmotion3 compressor is a highly original proposal designed to facilitate urban mobility. Attractive thanks to its dynamic, streamlined and futuristic style ; it is an interesting concept combining numerous benefits (size, safety and comfort) with "HYmotion" hybrid/petrol technology. This new generation technology creates a three wheel drive vehicle, benefiting safety and driveability and combining economy with an environmentally-friendly specification (CO2 emissions of only 47 g/kph in the combined cycle, zero in electric only mode).
The Peugeot HYmotion3 compressor concept is a means of transport with no affiliation to a particular type of vehicle. With its three wheels and its streamlined body, it is something of a missing link between two worlds which to date are quite distinct: that of the scooter and that of the car. With an electric motor in each of its two front wheels, coupled at the rear with a petrol engine, it brings into play very innovative hybrid technologies allowing each of its wheels to provide motive power.
In a world of intensifying urban traffic where everyone is trying to save time, where oil prices are skyrocketing and the environment is more than ever a priority, design departments are vying in ingenuity to develop solutions for the future.
Giving full rein to their creativity and expertise, two separate Peugeot teams converged on a similar idea and finally worked in tandem to develop a particularly original project: the Peugeot HYmotion3 compressor.

This "concept car", or rather "concept scooter", is based on the extensive experience of Peugeot Motorcycles, specialists in the scooter field, as well as the creativity and innovative capabilities of stylists and engineers working for Automobiles Peugeot. To create this concept, Peugeot was able to draw on its extensive experience in the world of transportation enabling each individual, according to their age or their needs, to choose from among the Marque's cycles, motorcycles and cars.
This vehicle offers an ideal mix of the benefits of a scooter and particular characteristics of a car.

Its design is based on three wheels for maximum stability, safety and driveability. Its width of 82 cm enables it to thread a path through urban traffic with all the efficiency of a two-wheeler. The front windscreen extends to the rear of the vehicle to form a highly effective shield against bad weather for the rider and passenger. In addition, regulations in France allow the vehicle to be driven with a B licence only, giving it a wide range of potential customers.

Finally, this vehicle incorporates HYmotion technology, also featured on other concept-cars in the Peugeot exhibition space at the 2008 Paris Motor Show. This new generation hybrid technology incorporates the supercharged petrol engine already featured in the Peugeot Satelis scooter. With a power of 15 kW (20 bhp) driving the rear wheel, it is combined with two electric motors, each with an output of 3 kW, located in the front wheels.
This configuration develops a maximum power of 21 kW (29 bhp) for a particularly low fuel consumption of 2.0 litres/100 kph and CO2 emissions of 47 g/kph in the combined cycle, or 0 in electric only mode. The design of the Peugeot HYmotion3 compressor, with its three wheel drive, provides positive benefits for both safety and driveability.
Thanks to its extreme hybridisation, the Peugeot HYmotion3 compressor concept creates a new benchmark in terms of safety (improved traction and braking), practicality and environmental-friendliness, offering original versatility at one with its environment.

Style
On the basis of a frame designed by Peugeot Motorcycles, Peugeot car stylists unveiled a resolutely sporty and avant-garde design which also captures the spirit of their latest creations, for example the Peugeot 308 RC Z concept car.
Two polished aluminium roll-over bars support the "bubble" which protects the two occupants. This use of materials is strongly reminiscent of the RCZ concept.
These bars make a significant contribution to the vehicle's overall personality and balanced proportions. In addition to the comfort provided by this structure, the bars end in a handle which can be used by the rear passenger. To preserve the vehicle's clean lines, there are no rear-view mirrors, this function being carried out by two display screens on the instrument panel offering optimal rear vision.
Viewed from the front the vehicle creates a strong impression of modernity with its row of light emitting diodes (LEDs) on either side of the base of the front windscreen. These provide highly efficient lighting and also ensure that the vehicle can be seen easily in traffic.

Tapered front mudguards, strong lines and hi-tech rear lights... each detail adds to the dynamism of the Peugeot HYmotion3 compressor. A dynamism which bears a strong resemblance to models in the Peugeot car range...
Operating principle: simple, efficient, automatic and transparent for the user
The vehicle's petrol engine has a power output of 15 kW (20 bhp). It is the supercharged 125 cc engine featured in the Peugeot Satelis scooter, this modern engine is widely acclaimed for its performance in its market segment.

In addition to this method of propulsion, the vehicle also has another mode of traction.
Two electric motors, one in each wheel, are present at the front of the vehicle. With a power of 2 x 3 kW, they are powered by "lithium-ion" batteries and recharged by an energy recovery system which operates during deceleration and braking.

Therefore, there are no mechanical connections between the front and the rear, everything being controlled electronically ("by wire"), allowing optimisation of the available space.
The Peugeot HYmotion3 compressor can therefore be ridden in a number of different ways:
in electric only mode (when starting up, at low speed and when decelerating, for a range of up to 10 kph at stabilised speed),
in petrol engine only mode, at a constant speed on the open road, when the engine attains its optimal efficiency,
with the petrol engine / electric motors combined:
during phases of acceleration for additional power ("boost" function), the latter can attain a maximum of 15 + 3 x 2 = 21 kW (29 bhp),
in three wheel drive mode, when road conditions warrant it.

In fact, the layout of this electric/petrol hybrid system allows three wheel drive under all circumstances, benefiting safety and driveability.
This hybrid technology, as well as its special innovative layout, is an important vector of research and development for Peugeot. Known internally as "HYmotion", this system is presented in multiple formats, featuring different types of engine, on Peugeot's stand at the Paris Motor Show. This concept demonstrates that the technology can be installed in any type of vehicle. In addition, different types of conventional engine can be combined with different types of electric motor.

HYmotion technology in this case is particularly miniaturised to ensure an environmental performance of the highest order.
The suspension and the structure are designed to take account of this technology's application. The parallelogram type front suspension (i.e. with tilting wheels) has a transverse damper at its centre and ensures optimal driveability and vehicle stability. These technical components are located on the wheel hubs, therefore reducing the vehicle's centre of gravity following the example of the low-slung tubular frame.
Braking, rendered more efficient by the presence of an ABS system, it relies on three ventilated discs and, above all, the front electric motors, which recover energy to recharge the batteries. This assembly (three wheels + electric motor braking) also reduces the braking distance by around 30% compared to a two-wheel scooter equipped with traditional brakes.

Another system contributing to the vehicle's efficiency is the STOP & START system. This system switches the petrol engine to standby mode during stop phases (at a red traffic light or a stop sign, in queuing traffic, etc.) or when the vehicle is being driven in electric only mode. This allows significant gains in terms of fuel consumption and emissions, particularly in dense traffic conditions. It also allows the petrol engine to be restarted instantaneously and "transparently" for the driver when necessary. Note that when being driven in electric only mode, the HY motion 3 compressor is ideally suited to city use since it generates no CO2 emissions or pollutants and is silent in operation.
The end result is a three-wheel drive vehicle offering reduced fuel consumption in the combined cycle of 2.0 litres/100 kph and CO2 emissions of 47 g/kph!

Performance doesn't suffer either, since with a maximum power of 21 kW (29 bhp), its acceleration and in-gear acceleration is equivalent to what would have been possible with a single cylinder 400 cc engine.
Here too, the hybridisation of technologies makes it possible to combine the benefits of an ultra-compact urban vehicle with three-wheel drive, while at the same time offering environmentally-friendly credentials.

Environmentally-friendly and efficient technologies: research goes on
To tackle the problem of greenhouse gas emissions, and with the prospect of fuel prices rising ever higher, Peugeot has made the reduction of fuel consumption and CO2 emissions a key facet of its product policy, both with regard to motor cars and motorcycles.
In fact Peugeot is making a key contribution to the position of the PSA Peugeot Citroën group as a world leader in the market of cars with a rate of CO2 emissions below 120 g/kph.

In the market for motorised two-wheelers, Peugeot Motorcycles is also very much to the fore. Peugeot Motorcycles has been innovating since 1996 when it launched the Scoot'Elec, the market's first compact electric scooter.
In 2006, weight and aerodynamic tests carried out in the wind tunnel saw the Satelis scooter obtain the best SCx on the market and, as a result, offer one of the lowest fuel consumptions in its segment.
Since 2008, Peugeot Motorcycles has included a 50 cc, 4-stroke scooter in its range offering particularly low fuel consumption, the V-Clic.
With HYmotion technology, benefiting from experience derived from previous technological demonstrators (Peugeot 307, 307 CC and 308 Hybrid HDi), the Peugeot HYmotion3 compressor represents a major advance in terms of "customer" benefits. These benefits include: safety, driveability, economy and also environmental-friendliness.
