The BMW i3 and BMW i8 Concepts.

BMW just unveiled two concepts - the fully electric BMW i3 was formerly known as the MegaCity Vehicle, and the BMW i8, a plug-in hybrid vehicle. One of the major problems with electric vehicles are the huge and heavy batteries. Well both cars use the innovative architecture and CFRP (Carbon Fibre Reinforced Plastic) to cancel out all of the extra weight added by the batteries.

Both cars will be manufactured at the BMW plant in Leipzig.
