...highway passing and rolling acceleration?

I suppose I know that the Tiptronic is slower from 0-60 and the through 1/4 mile because of a combination of drivetrain loss, not being able to get as good of a jump, and slower shifts. Is this theory accurate in the 993 as it is in my Audi A6?

That said, I am basically wondering how the 993 Tip compares to the 993 6-speed when it comes to passing acceleration in say... a 35-80 mph acceleration situation? Would a 6-speed still be quite a bit faster in that situation only even though it's not from a dead stop?

Also, what is the % loss of power from the crank to the wheels in the 6-speed and the Tip? I wonder how much less power the Tiptronic puts to the ground.

I searched like a good noob, but couldn't find these things.

 

Tip is slower in straightline performance primarily because it only has a 4-speed box (I have one of each). For spirited mountain driving, a tip in the right hands can be faster than a 6-speed, esp if the driver has mastered left foot braking.

 

Thanks David. And all this time I thought the Tiptronic was 5-speed like my A6. Guess not! I suppose I don't know too much about the 993's Tip because I've never been interested in getting a 993 with it. I am just wondering how it affects overall performance. (If it's as much of a handicap for the 993 as it is for... say... an Audi S4)

Anyone have any Tip vs. 6-speed drivetrain loss numbers? 12%, 10%? Higher? Lower?

I've been trying to look up dyno graphs of a 993 Tip, but no luck so far.

 

Euromagination........I have a 993 with a tiptronic, an S4 (2002) with a tiptronic and a Boxster S with a stick. The 993 is a daily driver on the 101 Freeway and the tip saves my ankle and knee. I never use the auto mode and manually control the shifting. If I don't it'll keep my RPM's about 1800. If the car was not a daily driver in heavy traffic I would never have bought a tip. It detracts from the cars proformance. However, I have adapted well and can get the most from the car shifting manually. Fred (fbfisher) has a tip and takes the lead on our canyon runs. Only the best drivers can keep up with him; 6 speed or not. I too would like to know the numbers though. With any luck someone has them.

 

shameless bump in hopes of someone being able to supply drivetrain loss numbers.

 

Assume several % worse power inefficiency, but the biggest losses come from the wider spacing of the 4 ratios compared to the 6 speed. When it up-shifts gears, it will drop more revs going to the next ratio, so that the engine is in a worse part of the power curve - this hurts alot. The 6 speed is already pretty poorly matched to the engine, so it can ill-afford even wider ratios...

 

I would argue that if the driver of the 6-speed is similarly skilled, then the 6speed will always be faster...
