I would like to see a good blend of lightweight but solid power in the M2. They can totally redeem the value of M to BMW folks if they get this right.
It actually means quite a bit. The original M3 was designed to be used as a homologated race car, meaning the engine choice was dictated more by the race class than buyers needs/desires. The M2 is not being designed for such a purpose. I6 is is/will be.

That's bollocks......

Until BMW themselves make an official announcement of what the engine spec will be in the car, everything until then is just internet speculation.

Until there is an official announcement, no one knows, but it is still fun to speculate. There is, in my opinion, no way BMW is going to put the M3/4 S55 into an M2 and call it an S55. They might put in the S55 with enough differences (such as different turbo and intake cooling systems) in the M2 to call it a N55B30T0, though. After all, the S55 internals will all fit, the R&D has been done to verify safety margins to well above the planned HP rating of the M2, they already have a supply chain for the S55 internals and the base N55 internals are supposedly riding the ragged edge of reliability at the M2 power levels.

That is my prediction.

A screaming turbo 4 would be fun, though, and would help with weight.

The N55 internals are pretty good (N54 are better though). It's quite a stretch to say 375 hp is the ragged edge for N55 internals though. There are plenty of people running that much power (and more) for years and the internals have been holding up. It's the ancillaries of the N55 that need to be upgraded to run 375 hp reliably.

Where I expect the M2 motor to take advantage of the S55 is in cooling and pretensioning of turbos. Let's face it, that's where the N54/55 is weak, cooling.

I've said it before, where I'll be curious is if the M2 gets the air-to-water intercooler on the S55 or goes with a standard front-mount air intercooler.

uhh....not all sources are the same.

check the sources of the info----that's pulled directly from the BMW test schedule....so not sure why you can't believe it. but you're not the only one....seems plenty of people love to pretend it's fake. oh well...your loss and your waste of time!!

this source has been bang-on correct for every model in the past...

I am sure it will be a tuned version of the N55. For those who want a normally aspirated engine those days are gone I am afraid. The demands of the fuel efficiency standards (particularly in the USA) have made it very difficult to get 300 hp plus in a normally aspirated engine with acceptable levels of efficiency. Of course the big race is for weight reduction, if BMW can get big weight reductions from the use of carbon reinforced plastics and introduce them into mainstream models (they say they are) then we may see a return to normally aspirated models to offset the costs of the use of these materials. The next decade will be fascinating in the automotive industry.

OK, maybe the ragged edge is exaggeration, but there is a difference between a tuner car and a production car when it comes to long term reliability. How many 380HP N55s have 100,000 miles on them and how many will realistically make it to 200,000 miles which is what I would expect from a BMW. How many of them see track time and get flogged like more than a few M2s likely will?

Like I said, it's not the internals, it's the ancillaries. That's what needs to get beefed up to make 380 hp reliable.

Those tuned N55s aren't frying piston rings or blowing head gaskets.

I would like the N/A e90 M3 V8 in a M2 that weighs no more than 3000 lbs. now that would be epic!

I would love if BMW brought back the n54 for this. By far my favorite motor BMW has ever produced.
(Ive owned s50, s52, s54, n20, s85 s65 etc)

I am most interested in what this n55B30T0 includes.

would you care to elaborate on why you prefer the n54 to some of the other wonderful engines you have owned? (s54, s85, s65)

Call me crazy, but I'd like to see BMW transition the M2 to being the "king of the M cars". I think with a tuned up M3/M4 engine, the M2 has the potential to be BMWs "super car". Think about it, the m3 is faster round a track than the m5, so why can't the m2 be faster round the track than the m3?

The m2 would appeal to people like myself who want a more focused track car, the m3/4 would appeal to folks who want more of a GT car, and the m5 is for those who want the ultimate "baun burner".

I wish that too, but never going to happen. Affordability and overpricing is what kills good products.

It would be, but BMW is out of the "screaming" engine business; it's now truck engines for all. Lots of torque and WAY lower revs. No choice really, now that M-division just tunes engines rather than designs/builds them.

If they do throw the N55 in the M2 hopefully it gets the same top mount water cooler as the S55 engine.

I'll start, I would love to see an old school ///M motor. An N/A straight 6...

3.6 Liters
8500 RPM redline
Direct Injection
380 HP & 315 lb.ft
That would do it for me. Doubt it will happen, but that'd be a perfect setup.

Large displacement naturally aspirated inline 6 with high redline. Like you, 3.6 liters. If porsche can do it why not BMW

Because they're chasing audi rather than leading anyone.

It's either the S54 or S65. What else? Some crappy, laggy, low revving truck motor? NO !

Because Porsche gets to lump their fuel economy and CO2 emissions in with the rest of VAG (Volkswagen-Audi Group), and VAG sells eleventy billion fuel sipping Golfs and Polos each year. BMW is independent, so they don't have the huge numbers to pull their averages down. Hence, every model must be a bit more efficient.

Also, even the low-end P-cas are going turbo in the next round. Both the Boxster and Cayman are getting turbocharged flat-4 engines.
