I can't see the sense in making the M2 a 4-cylinder and I don't believe that is going to become reality. I think its probably a lie to increse sales of the current model 135i and 1M coupe. Actually I thinking of getting one, just in case I am wrong!!
* The market demands a 6-cylinder sports car.
* M2 is not a high volume model, and I doubt there is much difference in fuel consumption.
* The F20 series chassis can fit a 3.0 litre six.
* BMW tradition has been built on 6-cylinder engines, and they have always been wonderful engines.
How can it possibly make sense not to give the buyers what they want?!?
