Mazda RX-8

Rear doors

Praised for its excellent handling and interesting if thirsty rotary engine, the RX-8 did have a design flaw – and it had nothing to do with that engine. The RX-8 had four doors, the front ones being hinged at the front and the rears at the rear. The rears couldn’t be opened unless the fronts were already open, and there were circumstances in which it would have been impossible to leave the car if you were sitting in the back.
