Audi has confirmed it will put the Audi A1 e-tron electric car into production in 2012.
The concept car, which has been unveiled at the Geneva motor show, has an all-electric range of more than 31 miles in city traffic, which can be extended to 124 miles.
It has a peak power output of 101bhp, and when the battery runs flat it is charged by a compact "range extender" consisting of a single-rotor Wankel engine and an electrical generator with a charge rating of up to 15 kW. Emissions are rated at 45g/km and average economy at 149mpg.
The Audi A1 e-tron electric car is being displayed to highlight Audi's growing plans to introduce electric cars "where it is appropriate for specific model lines and markets".
Rupert Stadler, Audi chairman, said: "In future our customers will be able to choose from an increasingly broad range of driveline technologies. To accompany our high-efficiency TDI and FSI engines, we shall offer electric power in the best possible forms for a wide range of mobility needs. The hybrid driveline will be followed by all-electric vehicles.
