Mercedes Benz Bionic
The Mercedes-Benz bionic car is a concept vehicle based on examples in nature, in which DaimlerChrysler has also transferred the diesel engine technology of the future to a fully functioning and practical car for everyday use.

Bionics – a combination of biology and technology – is a quite recent field of research which has nonetheless already made remarkable progress possible in different areas. Nature has provided ideas for high-strength materials, low-friction surfaces, dirt-repellent coatings and practical Velcro fastenings, for example.

Many of these inventions are based on more or less accidental discoveries from the animal and plant world. For the first time in the case of the Mercedes-Benz bionic car, the engineers at the Mercedes-Benz Technology Center (MTC) and DaimlerChrysler Research looked for a specific example in nature whose shape and structure approximated to their ideas for an aerodynamic, safe, spacious and environmentally compatible car. In other words, this was not a matter of detailed solutions but of a complete transfer from nature to technology – a first.

This required teamwork: biologists, bionics scientists and automotive researchers from various disciplines embarked on an extraordinary expedition into the animal kingdom which soon led them into the depths of the underwater world – and presented them with a surprise. It was not the fast, sleek swimmers such as the shark or dolphin that came closest to the ideals of the research engineers, but a creature that looks anything but streamlined and agile at first sight: the boxfish.

It has its home in the coral reefs, lagoons and seaweed of the tropical seas, where it has a great deal in common with cars in many respects. It needs to conserve its strength and move with the least possible consumption of energy, which requires powerful muscles and a streamlined shape. It must withstand high pressures and protect its body during collisions, which requires a rigid outer skin. And it needs to move in confined spaces in its search for food, which requires good manoeuvrability.

There is more to the boxfish than meets the eye: despite its angular body, it is an excellent swimmer whose cube-shaped structure is by no means a hindrance. On the contrary, the boxfish possesses unique characteristics and is a prime example of the ingenious inventions developed by nature over millions of years of evolution. The basic principle of this evolution is that nothing is superfluous and each part of the body has a purpose – and sometimes several at once.

The outer skin of the boxfish consists of numerous bony, hexagonal plates which are interlinked to form a rigid suit of armour. This bony, armour-plated structure gives the body of the fish great rigidity, protects it from injury and is also the secret of its outstanding manoeuvrability, as tiny vortices form along the edges on the upper and lower parts of the body to stabilise the fish in any position and ensure that it remains safely on course even in areas of great turbulence. It does not need to move its fins in the process, and can therefore conserve its strength.

Applied to automotive engineering, the boxfish is therefore an ideal example of rigidity and aerodynamics. Moreover, its rectangular anatomy is practically identical to the cross-section of a car body. And so the boxfish became the model for a so far unique automotive development project.

Equipped with a 103 kW/140-hp direct-injection diesel engine, the concept car consumes 4.3 litres of fuel per 100 kilometres (combined), making it 20 percent more economical than a comparable standard-production model.

BMW Mille Miglia coupe
The Mille Miglia concept coupe from BMW was created to commemorate the BMW 328 touring coupe which won the 1,000 mile Mille Miglia race in 1940. In the process setting an as-yet unbroken record for the highest average speed, 166.7 km/h (103.5 mph).

The 2006 Mille Miglia concept coupe was never intended to race, but it did feature at the 2006 race where it was unveiled. Built to pay respect to the winning BMW 328 Touring coupe, its drivers, and the engineers who created it, the Mille Miglia concept coupe shares similar lines to the original car but translated into BMW's contemporary style.

Powered by the same drivetrain as the BMW Z4 M coupe, the Mille Miglia concept has thoroughly modern underpinnings. However the design process that created the concept were based on traditional methods. Using clay and plaster 3d models instead of computer generated images.

The bodywork of the Mille Miglia concept coupe is made from carbon-fibre reinforced plastic, and its classic flowing lines hide some of the interesting shapes found on the BMW Z4.

The asymmetrical LED taillight cuts down from the top of the rear window and curls under the rear of the coupe. BMW say that this unusual layout increases visibility for following vehicles, but in reality it would probably confuse many drivers. Interesting feature nonetheless.

The 2006 BMW Mille Miglia concept coupe is longer, wider and slightly lower than the Z4 it is based on, but the 20 inch old-fashioned wheels are still quite prominent.

Entry to the Mille Miglia is via the rear-hinged canopy. The entire structure, windows and all, lifts up and allows the driver and passenger to climb in, where they are protected by an overhead X-frame roll cage.

GM Hy-wire

General Motors Hy-wire is the first drivable vehicle that combines a hydrogen fuel cell with by-wire technology. To show off this radically new architecture, the front and rear panels are made of transparent glass. Onlookers can see through the car from front to rear; the liberal use of glass and the absence of a hood also provide a greater visual command of the road for the driver. To reinforce this effect even the seat backs are open. There is no post between the front and rear doors, known as a B-pillar. Drivers and passengers have greatly enhanced legroom.

The X-drive, which allows steering, braking and other vehicle systems to be controlled electronically rather than mechanically, provides greater freedom for the driver. Drivers now have the option to brake and accelerate with either the right or left hand. The driver accelerates by gently twisting either the right or left handgrip, and brakes by squeezing the brake actuator also located on the handgrips. The handgrips glide up and down for steering, somewhat different than today's vehicles where the steering wheel revolves around a steering column.

The fuel cell stack, which produces a continuously available power of 94 kilowatts, is installed in the back of the chassis. Most of the chassis is 11-inches thick, tapering to 7 inches at the edges. The electrical motor drives the front wheels and is installed transversely between them. Three cylindrical storage tanks (5,000 psi - pounds per square inch or 350 bars) are located centrally in the chassis.

Scion Fuse
The all-new Fuse was designed to be the new Scion sports coupe icon. Its goal was to push the limits of a coupe concept by combining entertainment, digital technology, and versatility into one sinister looking package. Most importantly, its styling makes a visual statement about its intention to expand the performance envelope among affordable, entry-level sport coupes.

The exterior of the Fuse was the conception of Calty designers Alex Shen and Bob Mochizuki, who were determined to create a strong performance statement. Inspiration came from the "HAKO" super GT racing cars of Japan, commonly known as the JGTC series. From the side, the Fuse has a low, aggressive stance with a race helmet-inspired wraparound window that provides a panoramic view. The visor-like wraparound windshield is balanced by a strong C-pillar, adding a sense of security and protection.

At first glance, the menacing presence and dark undertones of the Fuse subtly hint there is more than meets the eye. The front of the Fuse glares at you with slim, high-mounted, deep-set headlamps communicating a serious and aggressive attitude. A massive rectangular air intake hints at potential for a large intercooler.

From the back, wide-body rear flares span the entire rear mass, encasing deep-set vertical taillamps. The dual exhaust also serves as fog and reverse lamps as lighting encircles each exhaust tip. Wheels are 20-inch custom-machined with LED's on the end of each spoke, which illuminate as turn indicators.

On top, two horizontal glass panels run the length of the roof, and slide open in both directions offering all occupants access to a personal sunroof. The rear window tapers down to a speed-activated spoiler.

True to the Scion tradition, the Fuse is equipped with extreme levels of personalization accessories. Headlights and fog lamps can be programmed to illuminate in various colors. Videos or images can be downloaded and viewed on a concealed LCD screen behind the front badge. And then there is the interior.

Volkswagen EcoRacer

The prototype consumes a mere 3.4 liters and has a maximum speed of 230 km/h. The EcoRacer is a Coup Yahoo: Coolest Concept Cars concept cars
