A central driver assistance control unit combines data from all these inputs to build up a 3D view of the world around the car.
The German luxury brand hasn't elaborated on the R8 Piloted Driving concept's self-driving abilities, but for this year's main CES (Consumer Electronics Show) in January, a working A7 Piloted Driving development vehicle was able to steer itself most of the way from Stanford, California to Las Vegas, Nevada.
As Daniel Lapinski, project leader for Audi’s automated driving programme, explained to us in Vegas, the autonomous A7 was only capable of driving itself in regular highway conditions. That said, the self-driving software and hardware completed around 97 percent of that 885 kilometre journey.
As far as the drivetrain goes, the R8 Piloting Driving concept uses the same all-electric layout found under the skin of the human-piloted second-generation R8 e-tron.
A total 340kW of power and 920Nm of torque is delivered to the rear wheels via two electric motors. That's good enough for a 0-100km/h time of 3.9 seconds, and an electronically governed top speed of either 210km/h or 250km/h, depending on the tyres fitted.
A 92kWh T-shaped lithium-ion battery pack is said to provide a driving range of around 450km. Using a fast charger, the electric R8 can be recharged in under two hours.
