Dynamic driving, revolutionary design, and pricy efficiency are a complicated equation for BMW.

Change very little on any given car and things start to feel quite different. More than football, engineering is the true game of inches—or millimeters, if we’re being honest. Look at the i3, and all the usual suspects are still there: 4 wheels at the corners, steering up front, doors on the sides, and seats in the middle. What this car does differently from nearly every other vehicle on the road is just a small deviation from normal. But it’s enough of a change to make it a wholly new experience.
