carlos ,you say they are not in the same league ,is it that much better?better than ferrari's ,m3's and m5's???10 time faster means an upshift in 0.0008sec. this is impossible it would brake the gearbox in 2,do you have the real value?
yes, the trick is in the two clutches. When one gear is engaged the other clucth has the next gear ready to declutch and engage at the same time the outgoing gear is disengaed, so it occurs simultaneously yielding such shifting speeds and most importantly almost no power interruption during the shift. This lack of almost no power interruption makes the double-clutch system the first "auto" that even accelerates faster than a manual (I believe its 0.2 secs faster than the manual in the GolfR32 in just the 0-60). Its also smoother than a single clutch sequential.
I expect nothing less from Porsche than this system, the only problem is to figure out how to make it handle the torque of the more powerful 911 variants. But imagine a 997 with the Turbo engine and the 997's balance, handling and brakes, and this gearbox = "can't touch this!"
Upshift for the SMG-II is 80msecs (0,08secs) and for the DSG is 8msecs (0,008secs). BTW the Enzo's upshift speed is 150msecs
I'd still get a manual though, I can't live without the clucth no matter how fast it is, its an integral part of the driving pleasure and experience for me, though thats just me and a personal preference.
