Self-Driving Audi R8 e-tron Supercar Debuts At CES Asia
The self-driving R8 E-Tron is also an electric vehicle, resulting in a marriage of two cutting edge technologies. Equipped with a T-shaped battery with a 92 kWh capacity and two electric motors, the R8 E-Tron delivers 456 horsepower and 679 pound-feet of torque. On the track, it can go from 0-62 miles per hour in just 3.9 seconds without the aid of a driver.
It has an electronically governed top speed of 130.5 mph or 155.3 mph, depending on the car's tires. When traveling at a more sensible speed, the R8 E-Tron has an electric range of just under 280 miles, more than double the 133.6 miles of its predecessor that had a 49 kWh capacity battery. And when it does run out of juice, the large battery can be charged "in significantly less than two hours" as a result of an onboard Combined Charging System (CCS) that allows for charging with direct and alternating currents.
The car's ability to drive itself is the result of several sensors, including a new type of laser scanner, ultrasonic sensors, radar sensors at the front and rear, an several video cameras. All of these communicate with a compact central computer to draw a comprehensive picture of the vehicle's surroundings.
It might be a while before you can buy one, as autonomous vehicles are still in the early stages of testing on public roads.
