Audi has taken the wraps off the new Prologue piloted driving concept.

Audi has unveiled the Prologue piloted driving concept at the Consumers Electronics Show in Las Vegas.

Essentially an updated version of the original Prologue concept, the piloted driving concept has an autonomous driving system which uses a laser scanner, several video cameras, radar sensors and ultrasound sensors that are mounted out of sight.  The information gathered by the various cameras and sensors are feed into a central controller known as zFAS (zentrales Fahrerassistenzsteuergerät or central driver assistance controller) which enables the model to drive itself.

Additional changes are limited but the concept adopts a hybridized powertrain that consists of a twin-turbo 4.0-liter TFSI V8 engine, an eight-speed e-tiptronic transmission (with an integrated electric motor) and a 2.6 kWh lithium-ion battery.  This set enables the car to produce a combined maximum output of 677 PS (505 kW) and 950 Nm (701 lb-ft) of torque. 

Thanks to the extra oomph, the Prologue piloted driving concept accelerates from 0-100 km/h in just 3.5 seconds. In terms of efficiency, the concept consumes 7.9 L/100 km (29.8 US mpg / 35.7 mpg UK) and has CO2 emissions of 185 g/km.
