Based on the all-new A6 Avant that opens for UK ordering this week, the new concept car features Audi adaptive air suspension and a new V8 TDI engine.
The new SUV will be powered by a new 4.0-litre V8 TDI engine, boosted by two turbo chargers, incorporating common rail fuel injection.
The lightest diesel in the world complies with EU4 emissions standards, has an electronically limited top speed of 155mph and reaches 0-62mph in 6.4 seconds.
When driving in muddy conditions, or even just on salt and water-soaked winter roads, the allroad quattro concept windows are coated in molecules which repels water and dirt.
Features that could eventually filter through to other Audi models include the Audi road vision system, an optical sensor able to recognize the condition of the road and its surface. The system informs the driver of potential hazards such as loose gravel or black ice.
The Audi lane assist system produces vibrations through the steering wheel to tell the driver if they stray across to the wrong lane.
Audi Side Assist, in turn, incorporates radar sensors monitoring the area behind and next to the car to detect vehicles approaching the allroad quattro, or driving in its blind spots. A light mounted in the exterior mirror on the appropriate side of the car warns the driver.
There are, however, no definite plans to put the car into production.
