MINI's third-generation Convertible has been spotted for the first time with its top folded back into position giving us a revealing look at the upcoming model. Previously the car was thought to have been heading to the Geneva Motor Show for its world premiere, but that didn't happen. Nevertheless, it will join MINI's lineup before the end of this year. As with its predecessors, the Convertible is based on the body and mechanicals of the three-door Hatch adding a conventional retractable canvas top that eats up some boot space while offering seating for four passengers. The powertrain lineup will largely mirror that of the 3- and 5-door hatchbacks with 1.5-liter three-cylinder and 2.0-liter four-cylinder gasoline units alongside a 1.5-liter diesel for certain regions, topped out by the John Cooper Works edition featuring a 228hp (231PS) 2.0L turbo four.
