BMW will reveal what its new electric and environmental sub-brand will be called on February 21.

The German manufacturer has been developing the new sub-brand under the project i banner since 2007 and its electric Mega City Vehicle will be the first model to launch in 2013.

BMW will hold a press conference on Monday at 2pm which will reveal what new car will look like and the new sub-brand’s name.

While BMW has already revealed its Mini E and BMW ActiveE, BMW said the new Mega City was “innovative and distinctive” enough to warrant having its own brand.

It's rumoured there will be full electric versions and a petrol-electric range extender version of the new Mega City model when it goes on sale in 2013.
