Audi A8 Hybrid Concept Car

Audi presents the Audi A8 hybrid as a technology concept at the Geneva Motor Show. Its two engines - a 2.0 TFSI and an electric power unit - develop a combined total of 245PS and deliver 480 Nm (354.03 lb-ft) of torque, enabling them to provide the confident driving performance of a large six-cylinder engine. And combined with the advantages of electric power, the consistent downsizing also pays substantial benefits in fuel economy - up to 45.6mpg is possible, corresponding to a CO2 value of 144 grams per km.

The Audi A8 hybrid utilizes a parallel hybrid system - a highly efficient principle that avoids any unnecessary friction and power losses. Interposed between the four-cylinder petrol engine, which delivers 211PS, and the eight-speed tiptronic is a powerful electric motor. It develops 45PS of power and a very ample 211 Nm (155.63 lb-ft) of torque. The two power units together develop a system power of 180 kW and 480 Nm (354.03 lb-ft). This enables the Audi A8 hybrid to accelerate in 7.6 seconds from zero to 62mph and to achieve a top speed of 146mph.

The Audi A8 concept car is a full hybrid. This means that it can be propelled by either the gasoline engine or the electric motor alone - or by the combined power of both. During coasting or braking, the electric motor acts as a generator that converts kinetic into electric energy and recharges the battery. The hybrid drive can propel the car on electric power alone at up to 40mph with a range of over two kilometers - enough for urban stop-and-go traffic.
