A day talking M2, M2C and M2 CS...

Good evening everyone, I had a full day with BMW M today featuring a close up look at the M2 CS and more which I can't say much about right now. No drive unfortunately, because this didn't fit in the total day schedule but I will pick up a CS over the coming weeks for a few weeks to give a proper look at living with it.

I met up with the project lead of the BMW M2 series, and I had the chance to ask him everything. Of course, he could not answer all, but shared a lot of information about the M2 CS that many of you guys might not know yet. (Or maybe do...)

While looking at his pre-production M2 CS and my M2C, we discussed his private M2C as well, which he upgraded with a few nice options as a KW Clubsport suspension kit and an Akrapovic slip-on exhaust. He truly enjoyed his own car on track and in the mountains. True driving enthusiast.

Let me share a few interesting details for you guys.

1. The Michelin Cup 2 tire on the M2 CS was specifically designed for the new CS, and is now available for us all to buy. The tire is major improvement over the standard one, which we all have been using the past years. It comes with the tire connect app sensors installed and has the velvet tire walls. I will get more info from Michelin on the tire early next week. First information has told me that the side walls are a lot harder to deal with heavier cars.

2. The roof on the M2 CS is a structural part of the bodywork! This is different from the way for instance I put a carbon roof on my car or a stock roof is fitted in a M2 or M2C. The bar that connects both top side arches of the roof is absent on the CS. The roof is made of two layers of carbon fiber pressed together with in the middle a honeycomb structure (check the attached photos). Never seen that before!

3. Weight saving! The carbon roof saves about 10-10,5 kg. The carbon center tunnel saves 2.5 kgs. The carbon ceramic brake option for the front brakes saves 22 kg over the M Sport kit with the red caliper.

4. The exhaust on the CS has two changes from the M2C. It has a new mid damper and larger CS style tailipes for an enhanced sound volume. I heard the car and the sound is not that different from the M2C. It is a notch louder.

5. The air ducts on the carbon bonnet are functional and push air into the engine compartment. The bonnet is surprisingly flat in comparison to the CS and GTS bonnets on the F8x M3 and M4. There is no real bulge.

6. The front splitter and rear spoiler were developed to be fitted in combo. They offer a considerable amount of additional downforce and also stability at high speed. The project lead suggested us to fit it only in a combination and not to mix the M Performance parts with the CS parts.

7. The story behind the color Misano Blue was an interesting one. Like normal many colors are tried, but they never found a Red or Orange they really liked and which fitted the shape of the car. Like HS doesn't work on the M8 GC, red didn't work on the M2C, I was told. They then looked at Blue again and found out they were limited to the colors the factory had available in their pallet. In the end, Misano Blue was chosen as a color that fitted their liking.

8. The new wheel arch stripes we all have seen are there because of homologation guidelines. New rules have been set across the world and they are installed because else the cars are illegal in many countries. The arches cover all the new guidelines across all the countries.

9. On the software side of things, the ECU tune has only 40 hp more and no other changes. The gearbox software is like the M2C, the differential has new software to cope with the new adaptive suspension and the steering software was also altered in relationship to the M2C. Let's see if we can get that stuff in our cars with aftermarket coilover kits.

10. The brake air cooling ducts in the M2 CS Racing (which I saw as well) fit on our M2 and M2C cars. Like the carbon door cards, the front bumper can be ordered via the Motorsport parts list and fitted accordingly. There was also someone who mentioned that there was a template somewhere to drill the hole in your stock bumper.

11. We discussed our common issues with our cars and BMW is aware internally what issues are common and which we ask warranty for, such as the rear lights and the crank hub. Surprisingly, the stone-between-barrel-and-caliper issue wasn't really a thing they had a solution for.

I have shared some photos of the CS that was on site which had some damage. We discussed a smaller disc and brake kit, but that is not a cheap solution. Choose the normal stock brake kit on a M2C seems to be a smart move, but I think CS owners will have to deal with a lot of scratched wheels. The caliper is damn freaking close to the barrel of the wheels.

12. Interestingly, the CS racing had a Alcon 6-pots front brake kit and stock 4-pots M sport rear brake kit.

13. Production numbers of the CS are unknown at this stage. It could be 2200, but also a whole bunch more. They will make as many as they can. Cars are in production now and the EOL (end-of-life) is October. European cars are build first so that they have a CoC before end of August since the S55 engine is not compliant anymore from September onwards.

14. The reason the M2C and M4C with OPF don't have the fart noise on shifting like the older F8x M3 and M4 is because of noise regulations. Cars have to become more quiet and therefore they had to remove this. It has nothing to do with the OPF addition to those cars.

15. Everyone that did drive the car stepped out with a big smile and enjoyed it a lot. M-smiles galore from anyone on this event. A few people who had experience from the M2C, said the M2 CS was a great step forward on handling.

If you have any questions, then please let me know below.

I know you're being sarcastic, that's obvious, since Adaptive Suspension works in tandem with the vehicle's logic.

It would of been nice to get some technical feedback on its benefits, in comparison to the static dampers or MP Coilovers but I guess this is a beggar/choosers situation, so I'll take what I can get..


Noob question, the functioning air ducts on the hood, does the engine or components get wet in the rain?

Curious if there is any commentary on handling characteristics between CCB and standard due to lighter weight.

Thank you sir! I would ask for M2C development

Why did they remove all the sound deadening, particularly above the rear arches?

Why did they use a front calliper with a fixed bridge in the US? It's difficult to change pads for track work

Why did they fit a solid back seat with no adjustable headrest? This means we can't run a Schroth Quick Fit Pro for the track.

Why is rev matching not an option in M drive or a button? The time I actually really want rev match is full DSC off on track.

Why did they use progressive rear springs?

Why didn't they make the cloth seats an option?

The M2C could of been an absolute slam dunk with a few non costly changes. Still love it though!

Regulations in some countries reguire that no part of the wheel be further out that than the bodywork. The add on flanges cover the wider tires / offset on M2s

Thanks MR. for the first hand, exclusive and great information!

1. I'm very surprised new carbon roof saves a significant 10+kg. Thought it's some 10lbs.

2. Question: are they saying the CS exhaust only differ in mid pipe and tailpipe with no difference in muffler?

BTW, Is it just me or from the picture with no direct sun cast, standing next to each other, the gold 763M works better than the black?

Interesting info.

Is the suspension geometry changed at all for CS spec cars ?

Is the smart tire connected via app and also integrated into the idrive on the CS ?

I saw the car irl yesterday. The air ducts have a kind of filter layer inside with above a thin layer of plexiglass.
That in contrast with the ducts of the M4 CS which are completely let open. Engine components can get wet here.
As a result I expect the air ducts of the M2 CS less functional.

wtf that would render the air duct completely useless despite of looking nice....can you provide some closeup pictures?

p.s.: not trying to hate or make the cs bad in any way....mine is arriving next month. just wondering about the deviation between marketing promises and the production car

Handling improved and they liked it more than the M2C, but be aware that was driven normally on PSS tires, not Cup 2's! We need to compare apples with apples and not apples with pears. I will put my M2C when it is done on the same tires and compare it with the CS, then we have a decent comparison between a M2C with aftermarket upgrades and a CS.

I feel a massive difference between the stock wheels and my FI R's over 210 kmh on the highway the lower unsprung massive makes a massive impact.

I still need to take my car on track to feel the cornering difference.

Question 1: No clue they did... That is not different between M2C and M2 CS I believe.

Question 2: They used what they had available from the M3 and M4 I think. Not sure why they opted for if it is different with the M3/M4. It could be a thing of cost level.

Question 3: Cost! Same seats as in BMW M3 / M4. CS models never come with seats that offer holes for harnesses. Only GTS will! CSL models won't either, because there is no cage.

Question 4: Old discussion, cleared years ago with the M2. It was an internal choice that was made. Porsche solution is better, but they simply choose differently. God knows why.

Question 5: No idea! I could ask when I see them again.

Question 6: Cost level! Existing seats are fine as it is. Want it do differently, get them reupholstered. BMW never offers two types of material for the seats. Nothing new.

No costly changes don't exist in a full production and homologation cycle. Any chance costs money and loads of it. It requires time to be discussed, implemented, produced, support bulletins written, parts system updated, etc, etc, etc, etc.

Homologation! Wheels need to be within the arches completely. About 70 countries are enforcing new rules on tire noise and fitment. Many are different from each other but this fix covers them all.

Sean, the stock roof is 14,4 kg. Edison Composites and Alpha-N's roof is 4,5 KG. This M2 CS roof is a touch lighter at roughly 4,0 kg.

Yes, that is what they were saying!

Unknown! I asked it and I did not hard yes or no. I looked the same with a touch more camber, but was impossible to determine. I think it is more close to being the same than being different.

Nope, it is not included. you need your phone for it. It is a Michelin thing, not a BMW thing and since brands keep offering closed OS's on their internal car media systems we can't easily install apps there. Else it could have been an easy integration via your BT in the car.

Also there is hardly any bulge on the bonnet. The Edison Composites bonnet must be a lot more efficient, since it uses the M4 GTS shape for the vents.
