Because they made such a big deal out of it when it was released. Actual improvements aside, they should at the very least lower the price commensurately - especially when they just raised the price on the car.
The car will take a hit on responsiveness and acceleration. How much and if it will noticeable remains to be known, but it's physics. |

You will never notice the change.

Rotational inertia should be very small for a driveshaft. Especially the difference between a steel/alloy one vs. carbon, given that there is engine inertia, gears, flywheel, diff, axles, wheels and tires attached. Most of those with a higher radius than the shaft. IIRC, it goes like MR^2, so I'm not even sure why they bothered in the first place.

Like I said, I am not arguing that it will make much of a difference, just how they are handling it on the customer side. There are actually some benefits in going to steel. But the replacement cost of the CF shaft is something like $2500 vs. a few hundred for the one in steel. To do a swap without adjusting the cost is kinda crappy, again, considering what a big stinking deal they made of it at launch. |

Mkting for Fanbois for sure (what isn't and of course I'm one too). With morning freshness another physical property comes to mind. Perhaps the steel loads up/stores some undesirable twist while carbon's stress-strain tensor can be 3d designed to avoid whatever you want. Carbon bike frames have some cool properties (though they cannot be repaired).

My guess is the carbon driveshaft was implemented not for rotational inertia but to reduce total vehicle weight. Given the cost and the small amount of weight saved it's no wonder they're getting rid of it. |

it's hard to describe how wickedly fast (and reasonably soul-less) the current gen M3/M4 is.
the RS3 would just be a nose heavy overboosted pig, in comparison. *just my opinion. obviously the RS3 is a huge upgrade over the S3. but the S3 felt chintzy to me.
