The Audi A1 e-tron is a plug-in electric car powered by a lithium-ion battery pack which offers a range of 50km, but, it's also backed by a very small range-extending, petrol-powered rotary engine. Once this is engaged, the car is said to achieve a range of around 116km.
To accommodate the 20-vehicle project, 200 electric charging stations will be set up thanks to the Model Region Electromobility Munich initiative provided by the German Federal Ministry of Transport.
The car outputs around 78kW and has a top speed of 130km/h making it the ideal city runabout also capable of long between-city journeys.
Audi and German institutions hope to collect data in terms of the demands the vehicles place upon the infrastructure and also test the cars for convenience and workability.
The project is scheduled to be underway by the middle of 2011.
