If I'm doing a dig or a 1/4 mile, I usually just let S do the work...I shift it in S-manual, select the gear and let it shift by itself.

..but when I am driving around a track or a twisty road, I feel Manual mode is more responsive. Sometimes I even feel it shifts faster but I am not sure if it's my head playing games...

That being said, there is not such thing as a fast auto on these cars...

Do you think Manual mode is just as fast as S-manual mode?

It has been discussed in some other threads about the responsiveness of M mode vs S or S+. Drag/dig/ 1/4 mile runs S (S+) is best due to it's extremely hard not to shift just right from 1st to 2nd, even 2nd to 3rd. I have also heard about gear shift knob shifting faster than paddles and vice versa, but no stats to actually back up any of it.

"there is no such thing as a fast auto" ..not sure what you meant by this but why do you think all performance cars are no longer purely manual, cause no one (except the flash) could shift that fast.

Overall S and M are equally fast in their own way for different occasions.

Thank you.

I meant that, on these cars -- the C63s, the auto (MCT) isn't as fast as a PDK, DCT or even a DSG...wasn't referring to Automatics vs Manuals.

The science is settled, there's no question that even the slowest MCT/DSG/PDK is far and away faster than manual. The only question is how much faster. When you look at the list below, our 100ms shifts are not at all considered 'slow'.

As for our cars, I doubt you can choose the correct shift points consistently better than the ECU/TCU. Pulling the paddle also adds lag, but as for the actual shifting action, I believe the speed is no different than in S+ mode.

FYI:
http://en.wikipedia.org/wiki/Shift_time
Shift times
A long shift time is considered anything over 625 ms
The average manual car driver: 500 ms - 1 s (vertical gear changes e.g. 1st-2nd, 3rd-4th, 5th-6th): 1s - 2s horizontal gear changes (2nd - 3rd, 4th - 5th, 6th - 7th). As well shift times can change depending on gear throws (distance between gears), its easement of movement, ergonomics of lever and age of gearbox.

Gearbox shift times (Fastest to slowest)
Bugatti Veyron (DSG): 8 ms
AUDI (DSG)(Also S-TRONIC): 8 ms
Volkswagen (DSG): 8 ms
Alfa Romeo Mito & Alfa Romeo Giulietta (2010) Dual Dry Clutch Transmission TCT: 8 ms
Ferrari 430 Scuderia: 60 ms
BMW M3 E92 with M-DCT: 80 ms
Ferrari FXX: Under 100 ms

Thanks for that list, BLKROKT.

Could have swore the GT-Rs shifted at least 60-80ms

It's Wikipedia. Take it with a grain of salt.

Is PDK and VW DSG the same just different name?

mthis

came across this . fastest gearbox out and 50ms shift time? http://blog.caranddriver.com/techy-g...-isr-gearbox/#.

for my 2.2 cdi 7DCT Manual mode is faster as it auto shifts at 4700 rpm whereas in sports mode it shifts at 4000-4500 rpm. Claims of 0-100 by company is 9sec which is prolly in sports mode. I got a 7.9s in Manual mode (auto shift). slight gravel and wet. tyres slightly under pressure.
