To be honest, I dont get why there's so much hate towards m2 CS.
The fact is, Stock m2 cs is lighter, more powerful than stock m2c. And stock cs has more heat resistant brakes, lighter wheels, and more grippy tires than m2c. Yes, no doubt someone can use aftermarket and make a M2C close, or even better than m2 CS. And Yes, no doubt M2CS price tag is idiotic. But people who like CS will buy a CS. People who like m2C will buy m2C, (or already bought one). If m2c owner want to spend money and make it better than m2cs, go for it. i just don't see the reason to shit on either car. |

An interesting thingy is, in gear accelleration 4th/5th/6th/6th M2C is a bit faster than M2CS because of different mapping. Just like OG M2 N55 was way more powerful below or around 2000rpm daily driving than S55 M2C. FWIW.
I'm guessing M2CS will be irl 10s faster than M2Comp on Nordschleife(not taking into account any favourable situations/temperatures) But as already stated by Sportauto in the end it's about the more powerful engine tune and the Cup tyres which make the CS seriously faster than M2C. Weight savings are nice offcourse(!) but don't do anything in this case on an already heavy platform to begin with. And I want a carbon roof for the fun of it and I want a tune and a Remus exhaust M2CS price in the Netherlands will be about 130-140k EUROS. I don't see the fun and benefit for me of it in that, so I keep on driving my M2Comp..... And I keep on dreaming about a GT4 PDK.... Cheers Robin |

Worth noting that CS tune should be the same on WOT as the competition everywhere below 5k2 (2200-5200 torque plateau of 550NM), and be programmed to hold much better to fuel cutoff. Because in the end, remember all of turbocharged BMWs have a torque to load based DME.
Partial throttle could be a bit different though, and I'm sure CS would be tuned for more drama. Like M4 base vs. ZCP, anyone thinking ZCP is weaker low down just don't know what they're talking about, or probably didn't ever sit behind the wheels of them at all.

I think what happened here is that, at some point during the S55 life cycle, BMW reduced the low end torque of the engine on all S55 tune variants. When the M3/4 were first launched, the official BMW rating for torque was 406lb-ft @ 1850-5500rpm, it has since been revised to @2300-5500rpm. Folks that switched from an early base M3/4 to a competition pack felt that reduced low RPM torque, which gave the perception that the Comp Pack was weaker in the low RPM. I certainly felt the difference switching from my 2015 M4 to my 2019 M4cs. However, this becomes a moot point for lap times since the RPM never go that low when a car is properly driven around a track.

Both cars have the same low-mid power and should therefore be very similar in in-gear acceleration, if anything the M2cs should have a slight advantage due to its lower weight. I think the results are mostly related to the different test conditions. The M2cs being tested on a hot day will have more lag and will not show as strong in in-gear acceleration tests.

I get where you are coming from, however, the weight loss going 763>788 is about 16-17lbs total. I have the 763s and absolutely love them AND can feel the difference.

Cornering speed differences beginning to end of lap in kph: 5, 0, 2, 3, 5, 0
Cornering g equal in 4 of 6 corners. (Differential in the other 2 = 0.05 g.) 0-40 kph acceleration time equal -- 1.5 seconds. Slalom kph differential = 0.5 kph. 1.7 meter difference in braking from 100 kph. Stop claiming the PSS weren't working. Again, when summer tires go "off" due to temp, testing is not possible.

Will anyone post a translation of the article? Any driving impressions within? This is the first car in years that has piqued my interest enough to get rid of my F80 for.

M2Comp is less powerful and differently mapped than M2CS. Just like you mentioned how your M4 '15 felt more powerful in lower revs than your M4 CS. Same engines different mapping. It off course can be the outside temps and test conditions. Weight in theory should do something but it does not in practice. It can be anything in theory. But in practice we see bigger differences the higher the gears are getting. On the other hand in practice we see a 16kmh higher topspeed for the CS which is a lot also for 'just 40HP' more on such a non aerodynamic car like M2. Anyway those are the numbers we have now.

CCB are only offered on the M2cs, they are not available on the M2C

Can you expand on this a little? What does Torque to Load mean exactly?

IMO the M2cs higher top speed on the track is a combination of better traction coming out of corners and the added power, it is not the power alone.

The last sentence, I was already thinking about that yesterday, but someone said a couple of times PSS should be ok in 1 degrees Celsius circumstances..... So again M2Comp had more favourable conditions etc but had less traction coming out of the last corner before the long straight. And cornerspeed of that last corner we do not know.... At the end it's about only two things: More power and more tyregrip. As stated by Sportauto. Cheers Robin |

Corner exit traction is a combination of tire compound, suspension tuning, aero downforce and e-diff calibration. And that is where the M2cs has an edge over the M2C. IMO the M2cs still had a traction advantage over the M2C despite the different conditions, but that advantage would have been greater if both cars would have been tested in the same conditions.

And IMO, the M2cs' better mechanical grip comes from a combination of tire tread compound, suspension/chassis tuning and aero.

IRL my M2C on PSS has a lot of tractionproblems. Which I generally like(sideways fun) , no worries, but on track for faster laptimes it's not the ideal setup, stock.
Suspension is too hard, just make it a tad softer on both ends and you're getting even less understeer and more traction. Take a look at the M2Comp Sportauto video on Nordschleife. Driver Gebhardt is experiencing more and more understeer. Thanks overheated PSS! Unfortunately Sportauto didn't mention any in depth suspension setup differences between Comp and CS. Does M2CS sit lower than M2 Comp? Cheers Robin |
