I doubt that the CF weave is any cheaper to produce. I think they are going a little bit down the Mini type of style with that roof

You're probably right

Still surprising to see it happening on such young vehicles

Sounds like BMW needs to do some more "extreme weather testing"

Apart from painting, I wonder what could be done to help prevent this?

I'm not sure if PPF or a wrap would help or make it worse

Perhaps a good ceramic coating?

[AlpsRider]

I think that ceramic coating would help but resin is going to deteriorate in the hot sun. Have a look at all of the milky headlight lenses on cars.

Agreed

The cheapest route would have probably been to just reuse the current MPP CF roof instead of designing and manufacturing another specifically for the CS

I did some digging and found that the larger weave is stronger than the small weave. The CS cfrp roof provides structural support wherin the other models the carbon roof is not a structural piece.

Why would it need to be more structurally stronger unless you plan to drive upside-down..

I much rather the weaker M4 carbon fiber weave..

I love the sugar cube weave of the roof, it's one of the things about the CS most compelling me to get one. Totally unexpected and pleasant surprise.

I suspect that any mitigation of twist/flex in the body or chassis allows for a more reliable control of vehicle trajectory. Arguably because the energy deposited through the components meant to control it aren't subjected to as much random fluctuation from structural components loading and unloading energy.

Body flex is like connected one end of the car to another with a spring. Over simplified, but imagine how much more complicated the suspension geometry would be if you added an extra damper that wasn't included in any calculation for controlling motion.

Edit: and as previously discussed....in case you want to stand on your roof, fist pumping, while proclaiming your superiority.

I'm in this camp. I like the large weave.

Great, they must of designed it with the Instagram generation in mind..

I'm already tired if listening to the 1M vs M2CS debate about where your money should go. Just listened to the latest bmwblog podcast.

I certainly understand we are at a point where cars are a bit too powerful for the street. Most modern performance cars are death traps without traction control. On the flip side the cars are getting safer. I'd rather have my kids in an m2 of any version over a 1M.

Now that I've trolled this thread I'm interested in the 1M commentary. Why not by a used Porsche over a 1M. Not because it's a step up, but because there might be more value in a used p-car vs a car that is work more now than it was when new. Or maybe that's the reason to buy so you can hopefully recoup some cost. The point is moot if you never sell, so where do you park your cash?

Park your cash in an index fund.

Buying a car that you will actually drive based on resale value is crazy, IMO. The only cars that should be treated as investments are cars that don't get driven.

I would not park my money in a depreciating asset like a modern street-driven car. You can get lucky and not lose your shirt (1M, so far...) but it's not what I would consider an investment.

Just like no one drinks those $20k+ rare whiskies, no one should drive investment grade cars. If you want to park money somewhere, do it in a real investment.

[medphysdave]

I should have used different words. Didn't mean to imply that it it was a savings strategy. Which do you blow your money on.

I thought one of the reasons that the M2C drives much better than the m240 is because they killed the adaptive suspension. Why would they add it back in the CS?

Your answer is the post from me that you just quoted

Is Adaptive Suspension something that can be easily turned On or Off by a button in the CS? Does it increase handling/performance?

Besides the adaptive suspension, the M240i has a beefed up normal 2 series suspension. The M2 has a shorter wheel base version of the M4 suspension. So they don't share the same parts at all.

I believe the M2 CS has an adaptive suspension button? Can someone confirm?

You can't turn off adaptive suspension.

I am curious . . . if there were a blinded study where drivers were placed in an M2C with and one without adaptive suspension, would the drivers even know one from the other?

If there was a convincing (significant) difference perceived, which would be preferred?

I get the fact that there are car buyers who want to ante up for the CS exclusivity - cool.

I do not, and will not buy into the notion that the CS offers anywhere near the extra $20-25K BMW is asking over the M2C. Adaptive suspension seems to be a major topic of 'justification' for a small chunk of the massive up-charge, yet, what is the advantage . . . if any at all?
