The n55 is in it final years which makes it a solid engine, the B58 is brand new and will no doubt have issues early days... I would like it but not in the next couple of years

I agree.... More than that, I think the N55B30T0 is a great engine, is currently better than the B58B30M0 in terms of performance and is well proven. To say otherwise you need to speculate on what the B58 might become.

That being said, the B58 is a great platform to start building on. Let's see where it goes before we put it on the throne.

I've got an M2. I've never owned an S55 or any other M engine from BMW, but I have driven the F80 M3 and E90 M3 several times. The engine in the M2 is excellent. I don't get all the S55 vs. B58 vs. N55 thing. I guess some are a little better than others, but not by enough that I care. I like the M2 engine a lot. I'm coming from 991S (3.8L NA F6 - 400hp), B8.5 S4 (3.0L SC V6 - 329hp), and then a 991 GT3 (3.8L NA F6 - 475hp).

Honestly, I don't think the S55, N55, or B58 engines really stack up. Hell, aside from the sound, I'd take the 2.5L turbo 4 in the new 718S over any of the BMW options. I guess what I am saying is, be happy with what you've got. None of these options is all that great when compared to the engine competition (718S, C63S, TT-RS, Vette GS, ATS-V), but they are also still very, very good engines. These BMWs are fantastic *despite* having boring engines.

Would you go back to the 991s or stay with M2?

That's not a fair comparison. Apples and oranges. Even the 718S with similar options is 25-30k more. I love the M2 for what it is.

I think the majority who are playing the "waiting game" will always be playing the "waiting game" and never really buy anything.

I somewhat agree. I had to put myself on a waiting list with a deposit to try and force myself to buy. I generally find an excuse to continue driving my beater Xterra. I envy my brother. He just goes out and buys a new vehicle when the mood strikes.

Don't hate the " waiting game playa", hate the " waiting game playa" 's game.

BMW has to lower the co2 values even more. I am not certain bmw puts an engine in new car with a higher co2.

I think they are better off using the B58 with much lower co2.

we will see.

The CO2 values are based on the fleet. BMW can have cars over the CO2 limits and under it. As long as the average across the fleet is under the limit, we should be good.

It's good that BMW is making a green 5 series and more hybrids. It should help compensate for some of the M cars.

Yes. Buy they want to produce as many as they can of the cars that help get UNDER the limit. And as few as they can for the cars whose CO2 limits may push them OVER.

This is exactly part of the equation why production of the M2 is limited and why X1 production is absolutely not !

If the N55 isn't as efficient as the S55 this could be the reason for a change, because removing some of the vehicles that drag down the average by making them more efficient with a different powerplant does allow you to produce more of them ..

So in other words.....

If it comes down to a choice between Michelin Pilot SS tires and the Continental sport contact ... that you would rather have what's behind door #3... a set of brand new Michelin pilot 4S..

I like your style ...

Exactly how is the B58 better? Maybe you can tune it easier but for less than $2k I can get 420 hp without any hardware changes from the N55. It's more than enough for how I use the car. Straight line performance isn't really why I want an M2 in the first place and I certainly wouldn't buy a less special and uglier car only for a more "modern" engine.

"What BMW has done to the N55 for M2 duty is make it sturdier, more durable and more stable, as well as more powerful, to insure that it can take the sort of beating M2 owners will likely give it."

As you can see there are a lot of things done to the N55 before they put it in the M2.

[RPM2-85]

I put a Dinantronics sport,(Not a full stage 1), as well as a fabspeed sportcat. I rock my buddies F30 M3 at highway speed now. Needs more rubber back there.

Turbo gives every last breath to redline. Smooth gobs of power everywhere. Cost me $1700 total including the install of DP.

IMHO cant beat this combo, and its a serious difference. Not some oh my butt dyno tells me its faster. It hauls ass now.

I would say my interest in a highly turbocharged engine like the S55 has further diminished. I can hardly hear the turbo over the great sounding engine with the Sport cat, and there is literally no lag up in the rev range. It hits really really hard.

we will see.

European norm (gram of CO2 per kilometer):
M240i: 163 g/km
M2: 185 g/km
M4: 194 g/km

Yes, it is a bit lower. 11.9% lower. I guess it's a factor but BMW sell over 2 million cars worldwide and how many M2's have been built? Do you really think they would take an expensive reconfig of the B58 just to make a very marginal impact?

As you can see the S55 isn't an improvement over the N55 in this respect. The M2 and the M4 almost have the same weight and to restrict max power won't change these numbers by much as they don't use max power in the tests anyway. These numbers have in fact very little to do with reality. An M2 should be taking 7.9 liter/100 km but mine took 11 liter/100 km in reality. 39% more than official numbers...

This is why I'm hoping for the ability to run wider tires on the speculated CS model. It sounds like you've really hit a sweet spot with your tune. Nice cost/benefit.

We can run wider tires on M2's now. Ill prob go with 255/275. maybe go to 285's rear.

Hi everybody,

I've just ordered my M2 LCI with an ETA in July-August (first one that comes to Poland is going to be mine).
The dealer confirmed with the importer responsible for M cars over the phone that LCI is going to have minor changes (headlights/taillights mainly) and that the engine stays the same as in the current model.
He also said that in 2 weeks time he'd call me with more details as the importer is visiting Munich and should have more details about the LCI when he gets back.

I'll let you know when he calls me with some more info as I'm also very interested about the possible engine change and told him to ask around when he gets there.

The B58 is better in a number of ways that I won't waste my time explaining to you because I'm not trying to change your mind. I don't want an M2 for straight line performance either but I also don't want an engine that is being phased out and was designed almost 10 years ago.

One could be tempted to say that you obviously have no clue.
