I'm in the camp of not liking the idea of a four cylinder in a hi-line car. What makes it even more irritating to me is that BMW has offered a DI six cylinder in Europe that would likely come close to the fuel economy of the turbo four, while offering more peak power (not sure about torque, but I think hp was around 270 or so). I think it would have been a better option for the base car, then bump the hp of the 535 to around 330.
