These are Manual gear ratios: 4.06/2.40/1.581.19/1.00/0.87 These are DCT gear ratios: 4.81/2.59/1.70/1.28/1.00/0.84/0.67 The only gear that is "too long "compare to DCT is the first gear and I want to say the first gear in DCT is "too short" and not suitable in stop and go situations unless you drive the car in softest (Efficient/D1) setting...

While this is slightly off topic, I think the manual gears make sense but I can't understand why the DCT has such a short first either. It isn't really possible to get grip in the dry in a straight line in first, so why not make it a bit longer?
I actually like how the DCT in the E9x M3 had much closer overall ratios and a 1:1 7th gear for optimum efficiency when cruising. Of course you'd need a much lower final drive with those ratios. 1-4.780 2-2.933 3-2.153 4-1.678 5-1.390 6-1.203 7-1.000 With a final drive of about 2.6 or so you would get a longer first, closer stacked 2nd to 7th and a similar cruising rpm. |

Just keep in mind the S63tu generates a lot more torque than S55. 576 vs 446 lb-ft (~30% more) measured by Dinan... These are the gear ratios of M3/M4 MT: 4.11/2.32/1.54/1.18/1.0/0.85 and 3.46 (FD) These are the gear ratios of M6 MT: 4.06/2.40/1.58/1.19/1.0/0.87 and 3.15 (FD) With respect to basic physic (F=ma), at any gear M3/M4 MT cannot accelerate (your feeling about torque) noticeable faster than M6 MT even if both cars can put the power down perfectly and that's why overall M6 is faster than M3/M4 from standstill or in rolling

Also, I have friends in Munich, so I'm thinking of European Delivery. I don't think they put manual transmissions in for the German market, so an M6GC MT would be like an exotic creature over there. If anybody's watching. Not a reason to do it, but I'm just saying....

Another endorsement from me for the MT. I just feel I have more control with the manual. Not that I've driven the DCT much, apart from on my initial test drive but I don't think I could have any more fun than I'm having now.

Which throttle setting do you manual guys use? I really like the response in Sport+ but miss the rev matching on the downshifts that is turned off when you put it on this mode.
To the poster complaining of the lack of torque in the manual - the torque curve is super broad on the M6 so I'm guessing you had it in too high a gear? |

I think the gentleman who's saying the torque isn't as potent/the gears are too long is unfortunately basing his opinion only on a(singular) test drive experience. I'm sure if he owned one like we do/drive it daily and you really understand how to maximize the transmissions potential, he'd feel much differently. To me, It sounds silly comparing the m3/m4 to the m6- because I have NO idea what he means by it feeling slow. Hahahaha one ride w/ me driving my m6- and everyone's

Wonder if installing a PedalBox to increase the responsiveness of Sport and Efficiency(why they call it this in an M is beyond me) would help, without losing the rev matching feature. Tried one out in the 750 with decent results.

I came to the same conclusion - the problem was with me, not with the car. I need to downshift to 3rd and either let it wind up until I pass, take the time to shift to 4th during the pass, or else ride the whole thing out in 4th. It does not help that some people try to play games with you. I have had to pass pickup trucks originally doing 45-50 and found myself doing 80+ by the time I got in front of them (assuming they don't pull into the other lane to block me). For that reason I tend to put it in 4th and ride it out. I just don't want to take my hands off of the wheel. The start may not be as fast I would like, but I win every time. However, it is for that reason that I do not fault those who prefer automatic transmissions because they want to go fast without the distractions and additional time needed, however small, to shift a manual. |
