As many say, I too like I6 engines, but the I6 engine is a good engine only in specific uses. It is not bad in the M135i, but alot of the power is not really necessary. On track the FWD Renault Mégane RS does very well with "only" 265 PS. I am quite sure the new Audi S3 with 300 PS, will be as fast, and probably even faster than the M135i. Is the M2 going after laptime and sprint time records? Maybe, but that will be disappointing for me. Look at the BRZ/GT86, a wonderful car, which with the right tires only, gets instanly much faster on track and in acceleration, with only 200 PS and NA 205 Nm.

One thing most of you forget is that turbocharging is no magic. Turbocharging is "cheap" power, but may cost even more if the get it right.
I like the idea of a smaller displacement I6 (BMW 320i and Lexus IS200 with 2.0l I6) but I don't see BMW doing that. N55 is the same engine as N20 but with two cylinders more. BMW has the N16, if like for the N20, we could then get a 2.4l I6, but I doubt BMW would do that for the M2 only, for cost reasons, just as they didn't give the 3.3l V6 for the M3, again for cost reasons only.

Do not forget to take into consideration the weight that turbocharging adds.

N20: 146 kg (TC 2.0l I4)
N52: 161 kg (NA 3.0l I6)
N54: 195 kg (TC 3.0l I6)
S54: 217 kg (NA 3.2l I6)
S65: 202 kg (NA 4.0l V8)
S85: 240 kg (NA 5.0l V10)

The more torque of an I6 is not worth the added weight over an I4. Another question would be wether the added torque got by a turbocharged engine is worth the added weight. For performance yes, handling, I'm not sure.

By the way, does anybody know the weight of the N63 and S63? Well, BMW did not release the numbers, the added weight compared to the S85 is shocking. It would not be easy to justify turbocharging.
