BMW finally pulled the wraps off of the 2014 BMW i3 electric car, laying clear the last details surrounding this car for the cities of the future. It's safe to wager that BMW placed a high emphasis on driving dynamics with the i3, because its little EV's 125 kw, 170 horsepower motor is the most powerful in this roundup. Depending on how close its carbon fiber chassis gets to the estimated 2,700 pound curb weight, it could also end up being the lightest. High power and low weight are two of the main ingredients when baking a deliciously fun ride.
