BMW is well on its way to building buzz throughout the car world with this preview of their new electric i3 Coupe Concept ahead of its official unvieling at the L.A. Auto Show. This three-door electric is currently just a design exercise by the German automaker, but that hasn’t stopped them from using both innovative and throwback techniques. Representing the best of technology today, the car’s battery and electric motor is strong enough to take the car about 100 miles, which can be doubled by a supplemental gas engine. The shell itself, however, is made with an ultra light aluminum frame and carbon fiber body that is bolted directly to the frame to allow for rear-wheel-drive instead of the uni-bodies more common today; definitely a nod to an era of cars that is quickly dwindling. Inside, passengers sit in what BMW is calling a “Life Module” (think safety), whose floor is lined with the car’s lithium-ion storage cells and components are made with renewable materials, including leather, wood, and wool. On the outside, traditional BMW trademarks remain but with a slightly more compact and curvy design. Aside from the Auto Show, you can expect to see this car buzzing around the streets in late 2013.
