BMW rolled into the 2012 LA Auto Show to unveil another concept for its coming 'i' eco-car brand.

This three-door model is another hint at what the brand could produce when it becomes a reality in late 2013 or early 2014. We already know the fully-electric i3 and plug-in hybrid i8 will be built.

The i3 Concept Coupe wears a carbon-fibre body, carbon fibre-reinforced plastic passenger cell, two individual rear seats and is dubbed by BMW as the "world's first fully networked electric vehicle." The Germans aren't specific about what the latter means, only that its BMW ConnectedDrive system ties in info from the car's onboard systems, your smart phone and "the outside world."

Power here comes from an electric motor developed by BMW making 170 hp and 184 lb-ft of torque. It drives the rear wheels via a single-speed transmission. The electric motor draws energy from a lithium-ion battery under the i's floor.
