I think that BMW added the carbon roof to the coupe only for marketing reasons. Performance benefit in terms of rigidity an weight are not significant between the steel roof and carbon roof with the rigidity of steel matching the performance gain of lighter carbon. The sedan does not have it since its the family option and most guys choosing it want more luxury features such as a sunroof.

improving the handling is a marketing tool for the M3. small things all add up, move the calipers inboard, aluminum subframes, CF roof. it all adds up - any small part on its own is not significant. but together they make the heavier e92 handles better.

a sheet of steel has the same structural rigidity from all angles. Carbon fiber however can be made to be more rigid when applying pressure from a certain angle based on the weaves of the carbon fiber. Its hard to crush a soda can vertically but its easy from the sides. Short of a crash in performance terms your never going to apply pressure on the roof from front to back, so they might've sacrificed some strength in that to make it more rigid from side to side ( its a bit more complicated than that the structure of a car tends to twist when going through a corner because when braking weight goes to the front so the fronts heavier and more planted, and of course the lsd is going to send more power to the outside wheel and probably a million other complicated things i dont understand.) That should be the basics of it, I'm no engineer, but no doubt the actual affect on the car is insignificant, but that's the point of these performance cars. Build every little part to the best of their abilities, 299 hp vs. 300, lets go for the 300. Save 2 lbs? sure. Shave the carpet in a gt3 rs to save a few ounces? why not. they all eventually add up as sayemthree said.

CF roof
Probably, but PLEASE don't go there. However, you can bet Vorsteiner will have a CF replacement roof panel for the sedan, with and without sunroof, like they do for the E46 coupe.

What do uoy mean by replacement? Do you mean that the original will be taken off so that there will be an actual weight saving?

As with the coupe, the CF itself will provide only slight weight savings. The real weight savings comes from the fact that you do not have the moonroof and its necessary hardware. |

"CAR" loves it - think they gave the E92 **** when it came out and E90 ***** (cheaper and does the job).

I don't think so... as suggested in BMW's website and previous posts... the there is no steel roof under the CF roof... the CF roof is glued to the car with steel supports in the middle...

I actually really like the E90 and E93 a lot and I also like the carbon fiber roof but I think it should be Coupe-only. The convertible is sporty but doesn't convey hard-core like a Coupe with a carbon fiber roof would. It might work on the sedan. Maybe.
