MotoringFile says MINI is developing a five door hatchback, something larger than the standard hatchback, for the North American market and it is code named the "F55." among the changes it claims are coming to the hatchback are these:
MINI will shorten the front doors and add two small, conventionally opening doors behind them. This will be much like the Countryman’s layout, but in a smaller package. Those rear doors will be on the small side, but still more usable then you might expect. Sources are telling us that the rear doors will extend from the trailing edge of the front doors all the way into the rear wheel arches and up to the gas cap on the right side of the car. The F55 will have four sets of standard door handles opening everything up.
