BMW i3 images and information leaked ahead of its official unveiling

It's not the first time an automotive manufacturer has had its party spoilt by naughty web users uploading top-secret images to the web, but the latest pictures of the upcoming BMW i3 not only reveal the styling but also say a lot about its innovative design.

The stylish all-electric car was due to be officially unveiled in three major cities, including London, New York and Beijing next week but images of the production ready version are currently circulating the Internet.
