Audi took to the 2015 edition of CES Asia in Shanghai to unveil the R8 e-tron piloted driving concept, the automaker’s third autonomous concept car based on the all-electric R8 e-tron. The vehicle packs the same electric drivetrain, delivering 456 horsepower, 679 lb-ft of torque and a 0 – 62 sprint time of 3.9 seconds. The self-driving feature is accomplished using an array of sensors, including a new type of laser scanner, several video cameras, ultrasonic sensors and radar sensors at the front and rear. The data is transmitted to the the central driver assistance control unit (zFAS) which generates “a comprehensive picture of the vehicle’s environment” and then adjusts the steering, gear changes and brakes accordingly. The electric range is rated at 450 km (279.6 miles), and the vehicle is equipped with the Combined Charging System (CCS), allowing direct and alternating current to deliver a full charge in less than two hours.
