BMW's electric Megacity revealed
Our computer image is based on the sketch and shows what BMW's first electric car could look like when it goes on sale in 2013.
The four-seater will be based on technology already being trialled in the battery-powered Mini E and 1 Series. It will also use a carbonfibre passenger cell to keep weight down.
The car is likely to be costly as a result, so BMW might lease it rather than sell it to customers.
The rear-engined, rear-wheel-drive car has a 100Kw motor beneath the floor and is anticipated to have a range of between 100 and 130 miles. It's bigger than a Mini, but smaller than the 1 Series.
The project is the first in a string of electric cars that the company says will eventually account for up to 12% of its sales by 2020.
