Audi runs R8 e-Tron prototype at 24 Hours of Le Mans

Audi's been promoting the fact that an "e-tron" would lap Le Mans this week as part of a demonstration of alternative fuel vehicles shown at speed just before the start of the 24 Hours of Le Mans. Joining cars like the Porsche GT3 hybrid and natural gas powered Volkswagen Scirocco that both ran Nurburgring, the Audi e-tron turned out to be an outwardly normal Audi R8 painted in a matte medium grey with bright green decals. 

Its battery sits behind the passenger cabin to optimise its centre of gravity, thus achieving a 42:58 weight distribution. Four motors drive the front and rear axles and maximum power is quoted at 230 kW (308 bhp/ 313 PS), while peak torque is an astounding 4,500Nm (3,319 lb-ft). About 70 percent of power goes to the rear. Audi says the R8-based e-tron will accelerate from 0 - 100km/h in just 4.8 seconds.

A cable and plug allow the Audi R8 E-tron’s energy storage to be powered by your household current of 230 volts/16 amperes. Charging time is about 6-8 hours when the battery has been completely depleted and goes down to about 2.5 hours when high voltage is used.




Press Release

Audi e-tron at 24 Hours of Le Mans

• Technology platform opens the 24-hour race

• Five-time Le Mans winner Frank Biela at the wheel of the Audi e-tron

• Le Mans vers le futur shows Audi concept for an electric sports car

Audi presents an Audi e-tron technology platform based on the R8 at the most important sports car race of the year. Racing legend
Frank Biela drove the purely electric powered high-performance sports car during the Le Mans vers le futur, a demonstration run for electric vehicles, giving Audi fans at the 24 Hours of Le Mans a peek at the fascinating future sporty electric cars.

Not one, but four motors - two each on the front and rear axles - power the wheels of the Audi e-tron, making the test vehicle a true quattro. With 230 kW (313 hp) and 4,500 Nm (3,319 lb-ft) of torque, the two-seater accelerates from 0 to 100 km/h (62.14 mph) in 4.8 seconds.

The test vehicle wrapped in the skin of an R8 demonstrates that the Audi e-tron belongs in the major leagues of electric sports cars. The package does justice to all of the specific realities of an electric vehicle: The battery is located directly behind the passenger cabin for an optimal center of gravity and axle load distribution.

The requirement specification for the production concept goes far beyond battery technology and the replacement of a combustion engine with an electric drive system. The interaction of all components has a decisive influence on efficiency, range and practicality. With the technology platform shown at Le Mans, Audi is providing an insight into the development work.

Design and package
The caliber of the car is apparent to the fans in Le Mans at first glance: Based on the R8, this Audi e-tron has a wide, powerful road stance. The trapeze of the single-frame grille dominates the front end and is flanked by two large air intakes.

1.90 meters (6.23 ft) wide while only 4.43 meters (14.53 ft) long and 1.25 meters (4.1 ft) tall - those are the proportions of a supercar. The wheelbase of 2.65 meters (8.69 ft) leaves ample room between the axles for people and technology. The sporty proportions offer enough room in front of the rear axle for the battery unit and the power electronics.

The special package of the Audi e-tron technology platform provides a 42:58 weight distribution between the front and rear axles and therefore ensures perfect balance and driving dynamics.

Systematic lightweight construction is a crucial prerequisite for efficiency and range - and this is also the case for electric vehicles. The Audi development engineers therefore draw on a core competence of the company for the e-tron. The body structure is based on Audi Space Frame (ASF) technology.

Driving dynamics
The normal distribution of the tractive power is clearly biased toward the rear axle. Similar to with a mid-engine 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.

Via the four individual motors, which are each connected directly to the respective wheel via a short shaft, the e-tron also controls the lateral dynamics. Similar to the sport differential in conventional quattro vehicles, these motors allow torque vectoring - the targeted acceleration of individual wheels and thus an active distribution of tractive power. This boosts driving dynamics 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 a trapezoidal-link rear suspension made of forged aluminum components - 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 still offers a high level of comfort.

The direct rack-and-pinion steering gives finely differentiated feedback. Its electromechanical steering boost varies with speed. Fittingly, the technology platform rolls on 19-inch wheels.

Energy supply
The energy storage unit is charged with household current (230 volts/16 amperes) via a cable and a plug. The socket is behind what used to be the fuel cap. With the battery fully discharged, charging time is between six and eight hours. High-voltage (400 volts, 63 amperes) reduces this to around 2.5 hours.

The battery isn't only charged when the car is stationary, but also while driving. They 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.

Interior and control concept
The interior evokes a luxury-grade racing atmosphere. As in the R8, its distinguishing characteristic is the monoposto - a large arc that sweeps around the instruments. Unlike the production R8, however, the Audi e-tron has a graphic display for indicating the driving mode located between two round-dial instruments showing the recuperation and boost level.

Similar to the new A8, the driver of this high-performance sports car can select the various driving modes using a stalk that is based on shift-by-wire technology.

This car looks simple and minimalis design but this car is fiat pand hydrogen have modern in hydrogen because this car use concept design for hydrogen car. Fiat has unveiled the Panda Hydrogen, a concept vehicle powered by an innovative fuel cell system, capable of delivering all the necessary power without the need for drive batteries.The Panda Hydrogen is equipped with a fuel cell system called "Full Power": it lacks a drive battery for the accumulation of electrical energy that in most fuel cell vehicles is needed for acceleration. Panda Hydrogen is the result of a joint venture between Fiat Auto, the Fiat Research Centre and Fiat Powertrain Research & Technology with the support of the Research and Environment Ministries. It features performances a urban use: it accelerates from 0 to 50 km/m in less than 5 seconds and can reach a top speed of 130 km/h. The hydrogen tank capacity guarantees the Panda Hydrogen a range of more than 200 km over an urban cycle. Refuelling time is very quick at less than 5 minutes, i.e. comparable to the time taken to refuel a methane car.The electrical power generation system is supplied with hydrogen at a pressure of 1.5 bars and oxygen contained in the air. It produces electrical energy so efficiently that 60% is available at just 20% of maximum power. The alternating current three-phase asynchronous electric engine and the transmission are located in the engine compartment together with the various auxiliary systems. Though Fuel Cell propulsion systems will not be widely available before 15-20 years, in 2006 Fiat will start a field research phase with some demonstration Panda Hydrogen fleets.

Paulin VR concept car futuristic for future

New Futuristic Design Paulin VR Concept Car with Picture 1

I don't think we've said this since at least yesterday, but when it comes to cars, Europe gets the best stuff. What you see above is only a concept, but it was dreamed up by Daniel Paulin, the gent who created Ford's C-Max -- which is a Europe-only offering -- as well as the original Focus concept and the FAB1 ship from the Thunderbirds film. Paulin left Ford, moved home to Sweden, and started the Paulin Motor Company. Its first product is this, a 2-seater called the VR Concept. Part Speed Racer, part sea creature, it's swoopy and planed at the same time. The lifting canopy is a pretty nifty evolution of Saab's Aero X jet fighter-style raising canopy. With that and the scissor doors, ingress and egress should be simple by even the most supercar-challenged body shapes. It would also make ejector seat installation a snap. Paulin is looking for partners to help put the car into production, and in the mean time will be producing three concepts per year, as well as an actual model for a motor show. As far as the VR goes, Mr. Paulin, we'll take it.

I suppose, these auto shows will never stop surprising us and car creators will never get tired of making new and completely great cars. Have you ever heard about Morgan? Yeah, but apart from a famous fashion apparel brand, it is the traditional British car brand, and it has officially announced that it is going to launch a LifeCar concept, that is a hydrogen-fueled car possessing a wood-frame body. This super car will be presented at the 2008 Geneva Auto Show.

The hydrogen is converted to electricity using a 4 stack hydrogen PEM fuel cell. Apart from 22 kW of electricity, the fuel cell produces only heat and water as by-products. The fuel cell made by QinetiQ operates at 45% efficiency, a significant advance over the conventional internal combustion engine. Electricity is directed to 4 electric motors/generators, each connected directly to a driving wheel. Not only are these motors super-efficient – 92-94% across their operating range - but they have inbuilt re-generative braking, recapturing the kinetic energy for when vivid acceleration is required (and reducing energy consumption still further). Whilst regenerative braking is not a new concept, current applications offer around 10% energy reuse, whereas in LIFECar, up to 50% of this stored kinetic energy can be re-employed. This regained energy needs to be efficiently stored and delivered. Historically this has been the job of batteries, which are rich in heavy metals, heavy in weight and limited in their ability to deliver or receive high power bursts of energy. LIFECar has shunned these in favour of a bank of ultra capacitors. These have the ability to shuffle up to 1000 amps back and forth, maximising energy storage during braking and delivering powerful acceleration.

The Morgan LIFECar takes a fresh look at transport, offering as revolutionary an approach to personal freedom as did the brilliant Morgan Threewheeler introduced by HFS Morgan nearly 100 years ago. The LIFECar is powered by a fuel cell that is sized to meet the constant load requirement of cruising (about 20% of peakpower) and as a result significant weight and cost reductions have been made over other designs. By recapturing energy during braking, maximum performance is available to LIFECar for acceleration from this unique mix of technologies. The initial concept was the brainchild of Hugo Spowers of RiverSimple, a specialist company investigating new ideas in environmentally sound transport solutions. In order to realise LIFECar however, several partners were needed to make the concept a reality. The project is based around hydrogen as the fuel source because when it burns the only emission is pure water. Hydrogen is potentially abundant and Spowers brought in Linde to the project for their expertise across the whole hydrogen supply chain from production and distribution through to their high pressure refuelling systems.
