To this day, Audi remains the only European manufacturer to have series-manufactured a hybrid vehicle, an honour it has held since 1997 when it brought out the Audi duo based on the A4 Avant. Drive power was provided by a 1.9-litre TDI engine developing 90 bhp assisted by an electric motor with a further 29 bhp. Both delivered their joint drive power to the front wheels, with a lead-gel battery at the rear of the vehicle providing the necessary electrical energy.
