BMW insider Scott26 has recently mentioned that the 1M coupe's replacement - the M2 will be powered by a turbo four cylinder (N20 based engine) and that it may have less power than the 1M currently has. Why a turbo four? Presumably, because the new M3/M4 will be powered by a twin or tri turbo reworked N55 engine (or its successor). So it wouldn't come as a surprise that the M2 (1M successor) will be powered by a turbo four.
I wonder then, what will become of the M135i F20? Perhaps this model will go away once the M2 is released for sale on the market. Surely, BMW would not sell a 320 HP six cylinder M135i alongside an M2 powered by a four cylinder with not much more power. This really is not new news. Scott reported this down sizing thinking before the 1M was even released for sale (see previous report). This is just the first time since then it has been mentioned again. Discuss!

"There is a lot of this car [1M] that will carry over for the next generation 1M in which that car will switch to four cylinders to which the M Division engineers are already working on the basics without time constraints or restrictions. E82 1M is showing what is possible in a small time-frame. F22 1M [M2] will show what is possible once you do not have restrictions."

tbh, 4 bangers suck.
not saying they don't perform, but they just sound weird, and vibrates too much

It makes sense. BMW is back to the whole each size up in the M line has two more cylinders thing.
M3 is back to six M5/6 back to eight so it makes sense that they'd slot the car under with a 4 banger. And hey I'm excited. It's not like BMW Motorsport doesn't have a great history with 4 cylinder engines |

I think the the technology has progressed to the point where a turbo-charged 4 could have a lot of potential. I drove the Mk1 and Mk2 Cooper S which is a great example of how well a super/turbocharged 4-cylinder can be applied into a small, fun car.
I will probably never sell my 1M but a small, quick, and agile M2 would really tempt me away from the Porsche that I want as my next ride in a couple years. These are some good times to be a car-geek, regardless! |

Wow an "extensively reworked and re-inforced N55 Six Cylinder"....
How do you think that will hold up to the N54? I could see that being a prime choice to put the Vishnu ST upgrade on if it really is that much stronger/powerful. Hopefully the real details of the engine come out at some point... |

"We had initially toyed with the idea of a 1M when we were conceiving the Coupe and did work with evaluation models then using the engine from the E46 and the upgraded E46 CSL engine but it proved to be too heavy for the car. [...] The initial engine proposal [for the 1M] was the N55 but they were having issues that cannot be solved within the time window. BMW greenlit this car in July 2009, now over a year later we see it as it [is] intended, although testing still commences until the launch. Valvetronic was the main cause of the time delay but BMW have spent some time on this and are using the N55 as a basis for the next M3." (http://www.1addicts.com/forums/showp...79&postcount=1)

You should find a STi with a catless downpipe and see if your opinion of 4 cylinder's exhaust note changes. The Subaru rumble is in my opinion an amazing exhaust note, rivaled only by the old big block v8s and the modern V12.

I am strongly considering a m2 as I want to step up in performance/driving enjoyment and I hope that an M tuned 4 cylinder can deliver that. |

The Subarus do sound good but do not sound like your typical 4 banger due to the boxer design

You can squeeze that type of performance out of a turbo charged 4 cylinder, it just requires bigger turbos which leads to more lag and running out of revs. Maybe BMW will do a dual stage turbo setup to deal with this and still allow for 350+ WHP. We'll have to see, either way I'll be holding on to my 1M for a while. |

The main reason for the unique Subaru exhaust rumble are the unequal length exhaust headers connected to the boxer block. When equal length headers are bolted up, it sounds more akin to a typical four cylinder.

i remember the auto bild writing about how the M1 (what they called the 1M back then) will have a four cylinder turbo engine with about 250hp and will be much lighter - that was about 3 years ago i think...

Interesting brief technical write-ups of 2009 (with designs) about the N55, thereby pointing out differences with the N54 (also check the comments):

YES. The N54 has forged everything. Pistons, rods, crankshaft, ect... Everything is stronger and costs BMW more to produce.
The N55 has all cast parts, which are not as strong as forged internals. This is the reason why almost every tuner only delivers (tunes) the N55 for 360 Hp vs 380 ~ 400+ Hp for the N54.
