The R8 e-tron made its first appearance as "the e-tron concept" at the 2009 Frannkfurt auto show. The name, shape and colour of the R8 e-tron were inspired 1982 science fiction film Tron, by Steven Lisberger. In 2010, as side show to the 24 Hours of Le Mans, then Audi R&D chief Michael Dick drove a few laps on the course, barely finishing because of the charging state.
Audi has unveiled a new version of its R8 e-tron electric supercar concept at CES Asia.
A statement released by the company said "The R8 e-tron piloted driving technical study is equipped with all of the functions of piloted driving. Data is acquired from the interplay of an array of sensors: the new type of laser scanner, several video cameras, ultrasonic sensors and radar sensors at the front and rear. Based on signals from these sources, the central driver assistance control unit (zFAS), a compact central computer, computes a comprehensive picture of the vehicle's environment."
Specifications:
The R8 e-tron 2.0 is fitted with a T-shaped lithium-ion battery shoe horned into the center tunnel and behind the passenger cell. It will be a rear-wheel drive vehicle and it can go a full 280 miles on an electric charge. The rear-mounted electric motors produce 456 horsepower and 679 lb-ft of torque, all funneled through a single-speed transmission. The sprint to 62 mph from just 3.9 seconds and top speed rated is 155 mph.
