A prototype of the 2015 MINI Cooper Cabrio has been spied once again while undergoing testing.

Seeing camouflage on the upcoming MINI Cooper Cabrio is a bit pointless since the design will be virtually carried over from the regular version, with the obvious exception of the roof which will have a retractable canvas configuration on the open-top model. While in previous spy shots we saw the more powerful S version, this time we are dealing with the regular MINI Cooper Cabrio since it has only one exhaust pipe.

Engine options will likely mirror those of the fixed roof version so expect a 3-cylinder 1.5-liter gasoline unit rated at 134 bhp & 170 lb-ft along with a diesel of the same displacement but outputting 114 bhp & 199 lb-ft. The aforementioned S model will make use of a 4-cylinder, 2.0-liter turbo gasoline motor generating 189 bhp & 221 lb-ft. Later on during the car's lifespan, a JCW version with the 2.0 engine will likely be launched with around 230 bhp.

We won't be too surprised if MINI will decide to show the 2015 Cooper Cabrio a month from now at the Paris Motor Show.
