Mini sold 301,526 cars in 2012; BMW sold 1.54 million of its own models. According to a piece in Autocar, analysts say the coming UKL1 platform that will form the skeleton of the third-generation Mini Cooper and coming front-wheel drive BMW 1 Series could be responsible for "more than 900,000 cars per year" all by itself.
That sale fire is fueled by the UKL1 wearing up to twenty-three bodies in total between the two brands, 11 for Mini and 12 for BMW, rendering hatchbacks, sedans, coupes, convertibles, wagons, crossovers and people-haulers from about 12.5 feet to 14.5 feet. In April the VP of Mini USA said we might find some current models don't make it to a next generation, but a graphic accompanying the Autocar story has them all there. If it's correct, then those 23 models will only base model lines and don't account for different engines and four-wheel-drive options for each model.
The big changes that would perhaps mean big sales for the Mini line are a five-door hatch with two smaller rear doors for children, the sedan talked about last year for Asian markets and an MPV perhaps wearing the "Traveler" name that could send the Countryman in a more SUV-like direction.
