BMW's quirky new i3

The side view of the new BMW i3 electric vehicle takes some getting used to, with no two windows the same size or shape. The i3 is high-waisted through the front door and then there's a notch for a taller rear-passenger window and the rear-hinged rear door and a narrow, tapering window at the rear quarter.

But through that time the engines – apart from in the R8 GT – have remained the same, as has the woeful R-Tronic gearbox.
