2006 Porsche 997 Turbo is faster as an automatic-tiptronic transmission than as a manual 5 speed transmission?

Dr Christian Troy asked:


How is it possible that a 2006 Porsche 997 Turbo is faster as an automatic-tiptronic transmission than as a manual 5 speed transmission?

this is what I read:

“According to official Porsche figures, it produces 480 hp, accelerates 0-100 km/h (62 mph) in 3.7 seconds with manual transmission and 0-100 km/h (62 mph) in just 3.4 seconds with Tiptronic S transmission, and has a top speed of 193 miles per hour.”

the manual ****** gets you 3.7 and the tiptronic which is an automatic gets you 3.4
everything i’ve read about automatics is that they are slightly slower than manual trannies. and tiptronic is an automatic..just with a different name. i’ve driven German tiptronics in BMW’s and Porsches before..i just didn’t know they were faster than manual trannies.
you know that all high end cars these days also use automatics like Maybachs, the new Audi S8 and RS6 turbo,..seems like automatics are faster than stick shift cars..but people say stick shift cars are more fun to drive around in.

tiptronic is an incredible revolution in the auto world created by the europeans. the japanese counterpart would be sportshift, in the latest hondas and acuras. when gauging the 0-100km/h, the car needs to be shifted once from first to second gear. the difference between MT and AT is the speed of the shifting. the tiptronic transmission is tuned so well that it shifts faster than a person would manually by depressing the clutch moving the lever and replacing the clutch.

normally the manual process is faster than your typical automatic transmission, but because the latest tiptronic technology is so great, its performance far exceeds the abilites of a person’s manual shifting.

I find it unlikely that a Tiptronic trans can equal or exceed the speed of the shifts capable in a manual (especially in the hands of experienced testers). Remember, we’re talking about a traditional automatic here, not a sequential manual gearbox.

It is more likely that because the torque converter acts as a torque-multiplying device, more power is making it to the drive wheels. This is the reason that drag racers in heavy muscle cars almost universally use automatics, as the torque multiplication helps get the car off of the line more quickly.

Bear in mind, this is just an educated guess, and also, when you are talking about high-powered cars, the conditions at the test venue, the condition of the car (greener motors with very few miles, make less power) as well as the skill of the driver can affect the test results by a few tenths or so, which is a huge difference when comparing sub-four second zero-to-sixty times.

Tiptronics are wonderful. The earlier models only had 4-speed — but that has been changed to a 5-speed…

And hey, if it’s good enough for Hurley Haywood as a daily drive — why not the rest of us?

I dont kno how an automatic would launch better than a manual but hey whatever is faster.
