Destined for an international market debut sometime in 2012, the ultra-green A8 is powered by the Volkswagen group's 155kW and 350Nm turbocharged 2.0 litre four-cylinder petrol engine, paired with an electric motor producing 40kW and 210Nm of torque.
In all, Audi describes a "short-term system output" of 180kW and 480Nm of torque.
The parallel hybrid system sees a disc-shaped electric motor housed in front of the revised eight-speed automatic transmission, sending power to the front wheels only.
Power for the electric motor is drawn from a lithium-ion battery pack, and the A8 Hybrid's overall fuel consumption is listed at 6.4 l/100km - compared to 6.6 l/100km for the existing 3.0 TDI diesel engine. The 0-100km/h run is over in 7.7 seconds, Audi claims.
The A8 Hybrid also offers an electric-only driving range of up to three kilometres at 60km/h, although top speed in electric mode is listed at 100km/h.
In all, three driving modes are available: the above EV mode, along with Drive, which leaves control of the hybrid system to the car's computer, and a Sports mode for more spirited driving.
An Australian debut for the A8 Hybrid has not been confirmed. TMR has contacted Audi Australia for more details, watch this space.
