2012 Audi R8 E-Tron
Audi unveiled its latest creation the Audi R8 E-Tron in Las Vegas, The Audi R8 E-Tron is a a full fledged electric production car .Learn more about the Audi R8 E-Tron specifications and features in the Audi R8 E-Tron review.
The Audi R8 E-Tron is going to sport four separate electric motors that would ensure that the Audi R8 retains the famous Audi quattro all-wheel-drive system. The Audi R8 prototypes have been based on the conventional R8 chassis, due to which the Audi R8 E-Tron dimensions are similar to the conventional Audi R8.
The Audi R8 E-Tron prototype had been displayed in a single tone paint sporting a lot more chrome work on ti that the conventional Audi R8 E-Tron does. The Audi R8 E-Tron has its electronic motors located at alongside its four wheels ensuring that each motor delivers power independently to each wheel.
The Audi R8 e-tron is a high-powered sports car with a purely electric drive. Its four engines provide a total power of 230 kW (313 hp) for splendid driving performance. The four asynchronous motors – two each on the front and rear axles – make the Audi R8 e-tron a quattro. Power is transmitted to the wheels via the single-staged transmission and short input shafts. The technology demonstrator enveloped by the R8 belongs to the top league of electric sports cars. The R8 e-tron provides a glimpse into Audi’s philosophy of electric mobility.
The rechargeable lithium-ion battery installed in the Audi R8 e-tron consists of single cells with a high energy density connected in parallel and in series, and ensures a high output. In the final design stage of the Audi e-tron, the battery will enable a range of about 250 km (155.34 miles) when operated in the NEDC cycle.
Thanks to recuperation the battery of the Audi R8 e-tron is also recharged on the road during the braking and deceleration phases – the four electric motors are able to recover a considerable part of the energy.
The Driving Dynamics
The distribution of the electric drive torque in the R8 e-tron distinctly favors the rear axle. The electrically driven high-powered sports car retains exemplary neutrality even at maximum lateral acceleration, hurrying along curves as if on rails.
The Audi R8 e-tron rolls on 19 inch wheels.
For the R8 e-tron Audi engineers exploited one of the company’s core competences: the body is aluminum; designed with Audi Space Frame technology (ASF), it weighs less than 200 kg (440.92 lb).
The electric-powered, two-seat Audi R8 E-tron could qualify as the world's first zero-emissions supercar.
Whenever it arrives, the R8 E-tron will join the Tesla Roadster in the marketplace for electric-powered sports cars. The Audi R8 E-tron will be powered by four separate electric motors to retain Audi's familiar quattro all-wheel-drive system. The E-tron retains the conventional R8's mid-engine proportions. E-tron's lightweight electric motors are located at each of its four wheels, delivering power to each wheel independently. In June 2010, an R8 E-tron prototype won a rally for modern electric cars in Austria, beating both a Tesla Roadster and Mercedes SLS E-Cell prototype.
E-tron's lithium-ion battery pack and control electronics will weigh about 880 pounds, according to Audi. Target range for the production E-tron is 150 miles.
Because it has no power-generating engine, the E-tron will technically be a zero-emissions vehicle, just like a child's radio-control car.
