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.
The photos show the lack of front radiator thanks to the omission of an internal combustion engine, which helps reduce drag and gives the front end a truly striking overall look.
BMW has also run with an idea Ford recently pioneered in its brilliant B-Max model, the removal of the B-pillar. This allows for better access to the rear seats when all four doors are opened.
Inside, a large colour screen provides all of the vehicle's information and an even bigger display acts as a media centre and satellite navigation system. This is all operated using BMW's iDrive system.
The fabrics used are said to be more environmentally-friendly than the standard plastics found in many modern cars, with the i3 decked out in natural fibres and a wood trim option sourced from sustainably managed forests of eucalyptus trees.
