Are the torque levels exactly the same between the base M3/M4 and M2 at 406ft lbs? Even a little more torque can really show up in a butt dyno.

They're identical.

First, Tag was referring to a comparison between MY23/24 G87 and G80/82.

Second, how are we going to compare anything to a MY25 G87 dyno chart when we are still probably 6 month, give or take, untill the first one hits consumer's hands...

I was meaning comparing a 2023/2024 M2 to a 2025 M2 once the 2025's are out in a few months. That would help answer some questions on this thread. If I meet someone locally in the future who gets a 2025 I would be willing to coordinate a dyno day.

Bless my manual transmission. I’m running 530 ft-lb with a piggyback. Time will tell.

All BMWs are underrated in power. You're suggesting that the 2025 M2 will be the only car in BMW's lineup that isn't underrated while the rest remain? I'm almost positive the 2025 M2 will make more power than the previous models. BMW NEEDS to increase power (imo) esp to keep up with competition. It also falls in line with the new power increase on the M3's and M4's.

Dyno pls

IND compared it with their G82.

Again, different dates and times and temps. They're showing the M2 with more area under the curve than an older M4. Even if they are the same, there's no way BMW would want to see that. Hence my statement that until someone runs them back to back, with a post M2 production M3/4, I will not assume anything.

Believe whatever you want but the data is out there, I just gave you one example.

Highly doubt you will find any valid comparisons with all variables being equal and simultaneous. As long as we are talking apples to apples, you should accept some of what is shown from respectable sources.

stock manual M3's were showing Dyno numbers closer to 500 in some tests, so I think there is a difference between the 2 and this 2025 upgrade will probably just have the same map for both cars. I doubt anybody would be able to feel the difference unless immediately going from one car to the other, but it may help with some of the low end grunt the G87 seems to be missing.

Thank iND for this one!

G87 M2 RWD - (100% stock / pre break-in)
BMW's Ratings
453hp @ 6250rpm // 406tq @ 2650rpm

Our Best Run Pre Break-in - Dynojet 424:
IND G87 M2: 464.59hp at 6910rpm // 412.85tq at 3050rpm
IND G87 M2 Crank (assuming approximate 15% loss): 547hp // 486tq

Comparison:
G87 M2 — 464.59hp at 6910rpm // 412.85tq at 3050rpm

Well it doesn’t NEED to… whats the competition? I only cross shopped with a Mustang GT if comparing to a RWD Coupe, and RS3 if comparing a turbocharged compact-ish sports car. M2 makes more power than both already. But yes, i get your point. We’ll see in a few months

[Ronin76]

I so want the 2025 model and options to be posted already…so tired of waiting lol. I know I will still have to wait for an allocation but give me something…SOMETHING BMW!!


I feel like an addict lol.

[BroDoze]

Next month...

Tell me about it - I'm first in line with a deposit on a '25. Gonna be a LONG summer/fall.

Same here and no issues yet! Should be fine as long as I’m not driving the piss out of it everyday.

Same here. I try to be reasonable. Honestly, I can live with replacing clutch or transmission if it comes to it, but I doubt it.
The car is most fun I’ve had in a while. A year in and I still look forward to driving it back home after work. Still happy to take it for a random drive. Didn’t feel nearly as enthusiastic about my F80.
580hp, short shift kit, rwd. Yeah baby.

Yours is the best looking modified M2 out there!



LOVE the color.

And I agree with you 100%. This is the MOST fun BMW I've ever had (9 over the years).

Were the conditions the same when they tested both cars? I've said it before, but I seriously doubt BMW is just going to make an on-paper adjustment to the car. All of their cars have historically been conservative with the numbers they list and real world results. I'm sure the dyno results will be different when comparing a 24 and 25 M2, the real question will be if anybody will actually be able to notice it which is much less likely.

[BroDoze]

That HP increase is PEAK increase - how much more “under the curve?”
I bet it will absolutely be noticeable.

It is actually quite a small change “under the curve”. The way the extra power (on paper) is achieved between the 453bhp (338kW) M2 engine and 473bhp (353kW) M3/4 engine is by extending the same 550Nm torque plateau from 5,870 to 6,130RPM.

Power is 2 x Pi x RPS x torque

So 2 x 3.14159 x 5,870/60 x 550 = 338,087W (338kW)
And 2 x 3.14159 x 6,130/60 x 550 = 353,062W (353kW)

So you won’t notice any difference until you reach 5,870RPM.
