Okay, but correct me if I'm wrong (doing this from memory...no research), the Cooper engine is built in a chrysler factory in Mexico. It is no secret that the quality control there is going to be less than that of the German/Japanese marques. And such a willing chassis should have more than 115 ponies to tug it around, without having to take the price step up to the supercharged S. I am thinking that a BMW engine would be more willing to rev, and could probably put out an additional 20-30 hp in NA form. My guess is that they just want to keep costs down, if the car is a hit, a few years down the line we will see a better engine.
