Porsche 991 Turbo: Which is Faster The Tiptronic or The Stick?
It is no surprise that Porsche’s Tiptronic electronically controlled automatic transmission is good, but it is a surprise to learn that it makes the 2007 911 Turbo quicker down the drag strip. Aside from special applications, the torque converter has always been considered a hindrance. In this case the Tiptronic even has one less gear, being a 5-speed. The 6-speed manual on the face of it should clearly out-drag the two-pedal car. Nay, it does not. Power-braking the Tiptronic loads the turbo and builds boost before the car leaves the line. To build boost in the manual-equipped car would require excessive slipping of the clutch. This delay in building boost gives the advantage to the torque-converter-equipped Tiptronic — the gain being a tenth of a second to 60 mph despite its taller first gear.

The ability of the Tiptronic system to quickly shift gears shaves time the whole length of the strip — pulling out two more tenths. This is because the turbo stays under load while the Tiptronic shifts — keeping the 480 bhp at work pushing the car. In contrast, the manual is given pause three times in the quarter- mile as the driver changes gears.

So after sequential and twin clutches, the manual looses
again.

I believe the Porsche Turbo has been faster with the automatic for the past couple generations.

Not having to play around with a gearshift frees your hand to actually wave good bye to people as you floor it.

Personally,

I could care less about a couple of tenths of a second. I would get much more satisfaction shifting my own gears (although both of my current cars have auto trannys). I understand that these new SMGs and DSGs allow anyone to drive faster, but there used to be a price of admission to high performance driving and there is nothing like having your passengers compliment you on not being able to feel you change gears in a manual. I have no doubt that these new gearboxes are better than manuals, but when I purchase my sports car, I will not consider anything other than a manual tranny. Maybe its my loss, but its my dollar.....

Your right stone what's a few tenths, buy a ZO6 corvette then and save yourself about $70,000.

Why do I need this to crap to go on grocery shopping, pickup dogfoods, drop off videos and watch idiots crashing their 911's to a back of a semi-truck. Why?

This is also true of the A3's dual clutch system. But I still like to shift! I guess I'm old fashioned.

Hello guys, dual clutches and sequentials do have MANUAL MODE.

They're not what you'd call real automatics.
