BMW evolves electric car with new concept (pictures)

The i3 Coupe concept, and the production car, will be rear-wheel drive. BMW positioned the drive motor, which makes 170 horsepower and 182 pound-feet of torque, at the rear of the chassis. The lithium ion battery packs, made up of individual cells similar to those found in laptops, integrate with the chassis floor. BMW is aiming for about 100 miles of range with the i3 production car, and expects it to take 4 to 5 hours to charge from a 240-volt source.
