Based on the Prologue Avant concept wagon that made its debut at last month's Geneva show, the Allroad features subtle light brown wheel arch extensions, new front and rear bumpers, and a ride height that's been raised by 77mm over its forebear.

Under the skin, the Prologue Allroad is said to feature an all-wheel-drive, plug-in hybrid drivetrain. At its heart there's a 4.0-litre twin-turbocharged V8 paired to an eight-speed automatic transmission with an integrated electric motor.

Together the petrol engine and electric motor can deliver a maximum of 540kW of power and 900Nm of torque. Audi claims the Prologue Allroad can complete the 0-100km/h sprint in 3.5 seconds.

There's a 14.1kWh lithium-ion battery pack in the car's rear that can be recharged wirelessly. According to Audi, the Prologue Allroad is capable of an electric driving range of 54 kilometres and should return an official fuel economy figure of 2.4L/100km.

The Prologue Allroad rides on an adaptive air suspension system and 22-inch alloy wheels. Stopping power is provided by 20-inch carbonfibre ceramic disc brakes, while the steering system works on both the front and rear wheels.

Colour treatment aside, the interior doesn't seem to differ much from the ones seen in the initial Prologue coupe and the more recent Prologue Avant.

Again, OLED (organic light emitting diode) displays rule in the Allroad. For the two rear-seat passengers there are two Audi-branded OLED tablets mounted to the back of the front seats.

Up front, there's a curved OLED touchscreen at the head of the centre tunnel, while along the centre of the dashboard there are touchscreens for both the driver and front passenger.
