The options in the leaked VINs thread did not list the Retractable/Adjustable front armrest (base M2 code 4AE). Is the armrest in the M2c no longer Retractable/Adjustable?

[M3_WC]

Wanted to know if M2C recieved electronic steering retuning, but Autocar just answered that question...Yes.

Dirk Hacker:
“We have altered the steering mapping, changed the spring and damper tuning and recalibrated the DSC system as well.”

You are speculating (hoping). There has been no hard data to support this, and hints (weight optimized twin turbo) that do not support your wish. Could be a throw away marketing statement I suppose.

People are reading that early statement wrong in the leaked Australia press release. When they were stating weight optimized “biturbo”, they were referring to the engine as a whole. It was a marketing fluff statement, nothing specific. I’d bet the bean counters didn’t let them touch the turbos for only one low volume car. Everyone was thinking the M2C won’t have air to water top mount, well it ends up being the exact same cooling setup.

Not speculating or hoping at all. If Frank van Meel lied, it's on him but @MR. mentioned that S55 in the M2C is exactly the same hardware-wise, it received a software tune based on his interview with him (FvM confirmed this). I probably couldn't tag @MR. properly here but I'm sure he can confirm it once again when he sees this.

According to FvM, the engine is the same as in the M3/M4 engine. It is only de-tuned to have less horsepower.

There was also some conflicting info regarding the suspension. This is what was stated in the EVO article.

Surprisingly spring and damper rates are unchanged – M chief Frank van Meel said he wanted to improve precision without sacrificing comfort. The dampers are passive items, because ‘the car doesn’t need adaptive dampers’, according to van Meel, although cost is also a factor.

I asked about the suspension in this thread to which MR stated the following.

Tag: 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.

And then there's this article from Autocar UK which falls in line with what MR said.

BMW M division’s head of development, Dirk Häcker, said the chassis revisions provide the new M2 with “significantly improved response and more progressive on-the-limit characteristics” than its predecessor. “We have altered the steering mapping, changed the spring and damper tuning and recalibrated the DSC [Dynamic Stability Control] systems as well.“ said Häcker. “it is still the benchmark in its class in terms of response and reactions, but it now slides with greater progressiveness and enthusiasm.”

I would like us to get further calcification on the suspension as well, but wouldn't go as far as saying FvM lied. At a minimum he either didn't understand or was not fully informed. The takeaway from this is trust the engineers that designed the car over management and/or marketing.

I noticed the conflicting info on suspension as well. For some reason I tend to believe the Autocar article and their source, being the actual head of development. Hacker would know every in and out of the M2C, more so than a figurehead like Frank Meel.

Autocar also mentioned electronic steering retuning. Evo only mentioned the DSC retuning. Both systems surely got retuning.

Maybe I am seeing things, but the ride height looks lower on the M2C. M2C wheel gaps look smaller.

It has a 5mm drop.

Well that would lead one to believe the Autocar article and their source on spring/damper tuning.

When comparing the specs data:

• M2 Competition weighs 55kg extra (1550kg instead of 1495kg);
• M2 Competition max width is 6mm longer (1990mm instead of 1984mm: different mirrors);
• M2 Competition got higher fuel consumption (but same ± 52 liter fuel tank) and higher CO2.

Yup.. could well be a marketing fluff statement.

It seems strange to me that they would just do a flash detune... leaving themselves open to looking truly stupid when masses of people retune it even just to M3/M4 levels (more likely beyond). But then, it would not be the first stupid thing BMW has done lately.

The new muffler for the M2c has two electronically controlled exhaust flaps. This is a completely different design when compared to the M3/4 exhaust with or without the Competition Package as they only have one exhaust flap.

Q: Can you explain why the new muffler for the M2c has two and what else if anything is different about its muffler compared to the M3/4?

Even these graphs are not a real representation of engine power curves but still good for reference. Look at the power band of the S55

Peak power of the S55 starts earlier than the N55 and continues all the way past 7k rpm. Even near redline at 7500 it makes more power than the N55 is making at peak power.

This M2C is going to be much faster. That 0.1 advantage on 0-62mph/0-100km/h really don't tell the full story of the S55's vigour

So we should be seeing pictures from Beijing tonight in the North American time zones, right?

Yes.

If this is been asked already my apologies...

BMWs press release for the new car states that there will be a particulate filter in order for the new European requirements for admissions to be met by the S 55. This issue led to the demise of the M3, and the M5 50 I production had to be paused in Europe in order for her to comply by adding the particulate filter.

It would be interesting to know if BMW is going to have particulate filters on all production cars. In other words will they be left off the cars produced for the US given the fact that they are not required for our emission standards?
