BMW i3 Electric Idea Sedan – 2013

BMW has finally given us our first authorized, unconcealed look at its advanced, all-electric city car. For now the i3 is tranquil labeled an idea, but this car is greatly added complete than the Megacity concept that preceded it. The four-passenger i3 concept is possibly the most advanced take on electric cars yet, and draws on BMW's familiarity with a fleet of 600 Mini E and 1000 BMW Energetic electric cars.

The i3 is built around a new skeleton concept called Life Drive, which divides the vehicle into sections for Life, the passenger section, and Drive, the power train and battery. For the i3, the bottom half of the car is the Drive section, and is completed typically of lightweight aluminum; the Life passenger section sits on top and is built since Carbon-Fiber Reinforced Plastic (CFRP). Employing this lightweight equipment keeps the i3's weight along to just 2750 pounds.

BMW says that CFRP is as muscular as but 50 percent lighter than steel. Better yet, it never rusts and supposedly offers better security than steel in a crash. CFRP only forms the Life sections shell, however, as expendable plastic panels form the i3's true framework. The i3's electric motor was developed by BMW because the company required fixed control over the feel and performance of its power trains. It is rated at 170 hp and 184 lb-ft of torque, and has single-speed diffusion.
