Listen, I get to enjoy my CF driveshaft. I'm pro CF driveshaft. But that doesn't make the steel driveshaft car distinctly inferior.

I didn't read through all 300+ posts but wanted to point out that the steel driveshaft is a 2-piece design because it cannot be made small enough (diameter wise) if they made it as a single piece. There is a critical speed frequency requirement for any driveshafts to be outside of the driving speed range of the vehicle. In this case above at least 180mph or whatever the ungoverned VMax for this car is.
For a 1-piece steel driveshaft to meet the CS frequency requirement, it would end up being a lot larger in diameter than the CFRP driveshaft and there is just not enough packaging space. However, two short steel shafts, no problem in making them a lot smaller in diameter, thus gaining some space for the required new emissions filters in the exhaust system. As far as whether one can feel the difference, I think if you are a seasoned evaluator of driveline NVH, you would potentially be able to feel the center bearing wobble as it tries to straighten out under high torque. The 2nd order u-joint disturbance forces are proportional to the angle of the joint. More angle = more Force. All this is wasted energy that is not being transmitted to the rear wheels, however small the amount is. It is what makes this car feel so damn connected from your right foot to the rear wheels. Plus, there is so much more weight in the 2-piece steel design due to having to carry a center bearing, extra u-joint, and just being steel is heavier than CFRP. I totally agree with the above comment of Quote:

As I cruise to work today, truly rolling, I can't help consider:
My 2015 (build date 4/15) has that CF Driveshaft (fuck me, I can feel the difference), has the original Sakhir Orange with the original gold flecks from some Japanese plant (not this bullshit Sakhir Orange II with different flecks of gold, whatever and wherever the eff that is), has the magnesium oil pan, hockey stick tail-lights, euro-coded adaptive led's (screw the moose), and 58.3 system software (you know, the one that totally changed the suspension but still before they began to suck the balls out of the throttle response) and it feels good. I'm 150% sure that everyone on the road beside me here knows all the above as well. Yeah, they know it. Haters. And i'm 200% sure that when I trade it in and mention all the above BALLER features my car has, i'm totally going to make my nut. I'm going to make BANK bro. Damn it feels good to be a gangsta........ *edited 'cause I forgot my hockey stick tail lights. Can't forget them.

The magnesium pan is smaller in capacity and limited to 1.2g peak lateral load. The Aluminum pan has more available capacity and is baffled internally for 1.6g lateral load. |

I couldn't *possibly* have been any more tongue-in-cheek with my post above and took a bunch of bullshit liberties with my statements....many of which were based on stupid arguments that people had way back in the day. But hey, good info.......I need to put winky emoji's in my posts more. Incidentally, i'm about due for my noon 1.6g lateral load.

Emailed my salesman who is in Germany and is going to get some new updated information for us concerning orders from this point forward up to November. Meaning, when is the NLT date to order and still receive the CF DS versus the steel one. Hopefully I will have some new information for you all here shortly.
