It's hilarious that C&D titled their test like that. I assume they're laughing at threads like these where nobody bothered to fact check their own numbers.

From their own published test data for the M2 vs the M2C:

0-100mph 10.2, 9.1 seconds
0-130mph 19.1, 15.9 seconds
60-130mph 15.0, 11.9 seconds

Of course it's not the least bit surprising the 0-60 times are very close as that is so much dependent on hooking up the tires, and the M2C has a ton of torque and it's pretty hard to hook the tires cleanly (from personal experience) as it comes on so hard.

So their own test data show the M2C to be significantly faster. The M2C will open up an ever increasing gap that becomes huge.

Do you have a source that confirms there will be a new M2?

Even if they come out with another M2 in 2022, it will have to bring more to the table than extra power. The M2C is so easily tuneable with a flash tune that the potential power output is already more than the stock chassis would handle. A new model will probably also be either 6MT or ZF8. I'm not fond of the new dashboard in the 3 series, which is probably what a new M2 will have. Get the old school classic M2/M2C while you can 😉. Of course being an M2C owner I have a completely unbiased opinion 😁.

I don't post here often to have any weight on my opinion, but thread after thread I see M2 and M2C owners bicker. I don't understand why there's all these arguments on whose cars are better.

Both the original M2 and the M2C are great cars in their own way and both have their pros and cons. I'll concede the M2C is objectively the better car, no denying that. Just sick of seeing owners trying to detract each others' cars when both are fine cars.

And there will always be better cars than both the M2 and M2C, so just enjoy what we have.

^^^ My thoughts exactly.

I suspect that most folks hereabouts don't track their cars on a regular basis so arguing about the superior performance of the M2C at the margin is silly IMHO.

A lot of it is just unresolved developmental stuff. On the playground, some people were absolutely certain their dad could beat up some other kid's dad. And maybe they could have, but the fights never happened. Fast forward 20-30 years, and all those unresolved questions come back up on forums like this. And this one is tame. Stick around long enough and you'll see stuff like this...

M2C Owner: I have no doubt my M2C could beat an M2 around the Djibouti International Raceway.

M2 Owner: Maybe, but I don't track my car, it's just a daily driver.

M2C Owner: Good luck with that. I used to have an M2 and I once tried to bring a dozen donuts home, and realized I forgot the cheese danish, and the car went into limp mode. The M2 just wasn't up to the task.

M2 Owner: You know there is no International Raceway in Djibouti, right?

M2C Owner: You use Comfort Mode on the highway, you're a witch!

I don't care what anyone claims, that S55 is a torque-monster; it was so powerful that they had to originally detune the power so it could keep traction on the original M4. Quite the opposite with the N55 and that's saying a lot.

I get that the M2 guys doesn't want to accept this, as it's human nature to claim what you own is better than the Jones but logic will dictate that M2C won this race before it even started..

1/4 mile data from C&D for M2 and M2C:

12.7@110mph, 12.4@116mph

That 6mph difference in trap speed is indicative of the substantial increase in power/weight ratio as is the 3/10ths quicker ET. Of course ET is far more dependent on the 60' time (how well you can launch the car and hook the tires in that first 1.8 seconds or so...unfortunately, they don't provide 60' times, so we can't evaluate their launch).

There is no doubt the M2C is faster. That article even said it was. There is always going to be something better and faster available. Be happy with your car! Stop lusting for something bigger and better. Learn to enjoy what you have because it is already unique in its own way!

The M2C is definitely a faster car (1/4 mile trapspeeds don't lie) and I commend BMW for tuning the S55 in the M2C to deliver power is a more linear and tractable fashion. I firmly believe that if you tune the M2C, you're going to negate what BMW sought to accomplish with the power delivery and TRACTION. All tunes increase low and midrange power and that simply overwhelms the tires as the torque surge is so strong. A tuned M2C will likely be slower in the 1/4 mile and one the road course because it will be roasting the tires and hard to handle.

I think the N55 and S55 M2s are great. I could have either, but it's really hard for me to not like the simplicity of the N55 and lightly used M2. In a 1/4 mile race, the M2 is not going to be much slower than the M2C and just a downpipe would make it pretty dang close. A conservative flash tune on the N55 would make it even better.

The N55 in the M2 is very tractable. My M235 makes similar power to an M2 and I love the flexibility of the motor. You can push the car hard on the street without the sense of it trying to kill you. The N55 is far easier to work on and MUCH cheaper to service. The N55 in the M2/M235 is mildly modded by BMW for reliability and hard use.

While the S55 is stellar, I do worry about the long-term running costs and potential issues. One very big and concerning issue in older, 50K+ mile S55s (being reported on the M3/M4 forums now) is the "intercooler" heat exchanger leaking coolant directly into the combustion chamber. While this type of intercooling is more efficient vs the N55's more standard air to air intercooling, the S55's intercooling requires a lot of moving parts, a pump, and fluid-filled heat exchanger. BMW's history with the long-term reliability of cooling parts sucks. We're now seeing this in the S55s. If the leak was really bad, it could hydrolock the motor or impact the oil so that it loses it's viscosity and results in a spun rod bearing. Either one will result in a $10-20K+ repair bill as the S55 repair costs are so astronomical and amusing.

If you want all out power, less power reducing heat soak, and the latest and greatest, the M2C is the winner. If you want better long-term reliability, simplicity, reduced running costs, and a car you can drive harder on the street, the M2 is the winner.

I changed to M2C because of one thing: the S55. I had some issues with the N55 in my OG M2 when driving hard so I see the N55 only acoustically as the better engine but for the rest it's not an exciting engine for trackdays imo. Heatsoak is only one point, it does not rev freely and is out of breath beyond 6500 or even 6000rpm to be honest. It doesn't have much headroom for tuning or you're willing to spend thousands without any warranty.

Nice engine but I expected more of it..
So if you want a more reliable engine and be faster on track and street M2C is winner. No contest. But you have to pay to play...I do understand that.

Enjoy your M2s great car

Cheers
Robin

BM3 allows tunes to reduce torque in whatever gear you want so you can have less traction issues. SO you could reduce target boost by 20% across gears 1-3 for example but have the full power of the tune in higher gears.

I think their DCT test was a 12.5 at 113. That's what they were comparing it too. That being said, I think that test was an anomaly as many other road tests show the 1/4 mile trap of the OG around 110.

As a counterpoint, I will say that I have an F80 6MT and no way I was running a 12.5 or 12.4 in the 1/4 mile. 13.0 at 116 was what I kept running. Traction on the F80/S55 is difficult to manage, at least with a manual. That's why I take all these arguments over tenths with a grain of salt. The trap speed does show the ultimate power of the S55 though.

No, the data I quoted from C&D was with the DCT for both...I included the links to their tests for each.

This is so pointless. The tests are not valid unless they take both cars out on the same day.
Both cars are awesome and each has its own pros and cons.

No surprise here. Sure, the M2C has marginally better performances than the M2's (source: http://www.zeperfs.com/en/duel5975-7280.htm and, for more details, http://www.zeperfs.com/en/match5975-7280.htm), nice (optional) seats, and cooler mirrors. But the price to pay is huge: a significant regression in terms of aesthetic (subjective) and sound (not so subjective) combined to a castrated engine delivering its maximum power at 5250 rpm (M2: 6500 rpm). Yes, the M2C's engine can rotate up to 7500rpm, but what the point if the power remains constant from 5250rpm? At low rpm, the M2 is even more torquey than the M2C. From a financial perspective, the M2C is more expensive and depreciates as fast as the M2, at least here in Europe. And if, with the M2C, the goal of BMW was to put back the M2 well ahead of its main competitor, the TT RS, they clearly failed: http://www.zeperfs.com/en/duel6234-7280.htm.
At the end, both M2s are still pretty awesome and fun to drive, but for a possible real improvement of the M2 concept, my 2 cents is that it's better to wait for the M2CS (if not too extreme nor expensive), or for the M2 2.0 and its promising S58 engine.
Now, for folks wealthy enough to buy an M2 only to track it from time to time, and who don't care at all about losing its warranty or about its residual value, it makes sense to upgrade to the M2C and its S55 easily tunable to >500HP and with excellent cooling performances.

I almost thought you were joking here. Yes the M2C is rated at 405hp @ 5230–7000rpms (USA spec), and the point is completely about the "area under the hp vs rpm curve"...it's massive throughout the 5200-7000 range and results in the car pulling like a wild beast well past 7000rpms. Peak hp quotes are actually not all that important since what really matters is the area under the hp vs rpm curve and of course proper gearing. Case in point my E90 M3 is rated at 414hp at 8300rpms...the M3 screams like a banshee from 6000-8400 and hits a peak at 8300, but it has a lot less area under that hp versus rpm curve vs the M2C even though it technically reaches a higher peak hp.

TLDR -- one would much rather have a large area under the curve with constant HP output from 5200-7000rpms than some motor that reaches a similar but spiked peak HP value -- the former will always be significantly faster.
