Post M2 Competition: Questions for the Beijing Auto Show

Wanted to start a thread where everyone could post serious technical questions on the M2c that can be asked at the upcoming reveal in Beijing. Hoping that any member/s that will be attending the reveal would be so kind as to get in the ear of BMW on our behalf.
***Looking at SCOTT26

Please check the Q&A first before submitting any question/s.

Please keep all subjective comments regarding the aesthetics of the M2c to yourself.

Here are a few to start...
  • Are the turbos the same ones that are found on the S55 for the M3/4?
  • A picture from the EVO magazine article appears to show the M2c has a different looking muffler than what's on the current M2 or M3/4. Is it a bespoke muffler for the M2c?
  • Is the exhaust a single cat back as found on the current M2 or a dual cat back as found on the M3/4?
  • Was any engineering done to further tune the exhaust note of the S55 for the M2c?
  • Is the engine oil cooler located underneath the engine as found on the M3/4?
  • The EVO article states that the M2c weighs 55kg more than the outgoing M2. What is the weight distribution for the M2c?
  • The EVO article states the following, "...while at the rear the M division has used ball joints in the suspension for greater stiffness and precision." Can you please expand on this?
  • Will 18" inch wheels be offered that will fit with upgraded brake option 2NH?

I can answer exhaust question. It has to be dual pipe like m3/4. Two gas flow coming from two turbo need to go thru 2 cats asap for maximum cat efficiency and quickest cat heat up. They can't merge into one prior to cat because efficiency will be lost. There is absolutely no reason to merge them post cats, at best there is a resonator somewhere in the middle pipe so it won't sound like two 3-cylinder.

That's why there are very few twin turbo use single pipe exhaust system.

Agreed. Also, folks need to understand that the S55 in the M2 is the same engine in the M4/M3, therefore same locations for oil cooler, intercooler, etc. Detuning is simply performed thru software change to reduce the horsepower. It will be simple to retune M2 engine for horsepower gains.

Are there any suspension geometry changes? Specifically - any additional negative camber front/rear?

I would not worry about the exhaust note of the coming S55.

The 1M, 2 Turbo`s, did sound bad ass, when firing her up early in the morning , the whole building shook

So I do have confidence it wil sound better than in the M3/4, FWIW

-This question isn’t necessarily serious, nor is it technical, but I really need to know, is my LCI M2 really going to be worthless when the M2C is released?

Not worthless, but surely the value will fall hard.
1. S55 engine
2. The chassis is stiffened with carbon strut brace spanning the engine bay.
3. Other small upgrades.
4. Literally the same price.

People say all good things about the N55. But look at C63, people also say good things about the 6.2L V8. However, the "bad sound", laggy 4,0L biturbo, still took over its place.

This was not mentioned in any shape or form. After looking at the car, I did not feel there was any difference on those points to the package, but that is of course hard to determine from just looking.

MR: Nope, only a brand new exhaust was developed, which I haven't heard properly.

- Is the engine oil cooler located underneath the engine as found on the M3/4?

MR: The set up is similar as the M3/4.

- The EVO article states that the M2c weighs 55kg more than the outgoing M2. What is the weight distribution for the M2c?

MR: This has not been communicated.

- The EVO article states the following, "...while at the rear the M division has used ball joints in the suspension for greater stiffness and precision." Can you please expand on this?

MR: There is less roll in the vehicle while steering. The base M2 had this quite a lot. The car stays more flat and is more compliant on the road without loosing comfort levels. The package is not as hard as the M2 with M Competition suspension. The suspension is further tuned to enhance the ride quality.

- Will 18" inch wheels be offered that will fit with upgraded brake option 2NH?

MR: Both wheel options fit the M Sport brake kit.

The current m2 doesn't share the nose with the standard 2 so i would think there's no reason to think that will change in the future.

Here's one more for the show:

- Is the 'crooked' seat position fixed in the comp?

For the new front brakes, do they have quick pad swap windows (versus having to remove the caliper to change brake pads)?

MT question...

Inside the transmission, the new carbon fibre friction lining in the baulk rings provides more comfortable gear shifts, and a dry sump lubrication system ensures a more efficient supply of oil."
So nothing changed.
Excerpt from the M2 Technical Training 2015 document provided by Artemis in his response here, confirming it had previously been mentioned.



Need further clarification if the MT has indeed been updated/revised or not.
