Utilising two power units – a 2.0 TFSI engine and an electric motor – the Audi A8 hybrid has a combined output of 245PS and 480Nm of torque, giving the car the same outstanding performance as a large-capacity conventional six-cylinder engine.
This systematic downsizing demonstrates significant fuel-consumption advantages, the average fuel consumption is only 45.6 mpg, equivalent to CO2 emissions of 144 g/km.
The Audi A8 hybrid uses the parallel hybrid configuration – a highly efficient principle that avoids unnecessary friction and power losses. The powerful electric motor integrated between the 211 PS four-cylinder petrol engine and the eight-speed tiptronic transmission can supply a further 45 PS to the driveline, as well as 211 Nm of torque.
The A8 design study is a full hybrid, that is to say the petrol engine or the electric motor can propel it either separately or together. In the pure electric drive mode the car can reach 40 mph and cover a distance of more than a mile.
