The A1 e-tron comes with an electric motor producing 75 kW (102 PS) of power (45 kW / 61 PS continuous) and 240 Nm (177 lb-ft) of torque (150 Nm / 111 lb-ft continuous) juiced by a 12 kWh lithium-ion battery pack. The range on the A1 e-tron solely in electric mode is 50 km (31 miles). A range-extending engine helps improve that number to 250 km (155 miles).

That range-extender is a 15 kW single-piston rotary engine used to charge the batteries as the car is running.

The emissions and fuel-economy numbers look good but they're not zero given the range-extender. Consumption on the European cycle is 1.9 liters/100 km and CO2 emissions are very low 45 g/km.

Top speed is 130 km/h and the 0 to 100 km/h sprint takes 10.2 seconds.

By the middle of 2011 the first vehicles should be hitting the road, while at the same time 200 new charging stations will become operational.
