997TT manual v tiptronic
Discussion
At the launch the press picked up on the fact that despite being 35kg heavier the tip accelerates faster 0 to 62 than the manual. Porsche themselves make reference to it in the brochure and price list. All down the the auto cog swapper being faster than a humble driver. Fair enough I guess.
What is a little odd though are the gear ratios. Generally speaking you would expect the intermediate ratios of a 5 speed tip box to be slightly taller gear for gear than a 6 speed manual. And on the 997TT they generally are except that second on the tiptronic is shorter than second on the manual. Anyone know why? Surely not to boost the 0 to 60 time for the tip??
Also at the top end both cars are claimed to do 193. However according to my calculations (assuming a combined wheel and tyre diameter of 0.655m) in the manual this comes up at about 6800rpm whilst in the tip it would be 7200. If the manual were to rev to 7200 it would be doing over 200mph.
Any thoughts?

In one of the Pork mags they said the main reason the tip was faster is because in a standing start you can rev the engine really highly whilst keeping the brakes on (due to the new electromagnetic clutch),which you couldn't do with the old system. When you let go, you accelerate much faster as a result.
Agree on why the Tip is currently faster - if you look at the other times (overtaking etc) the story is different. Other than the obvious problem with a Tip, the major one this time is that with a DSG box supposedly coming out for the 08MY car, a standard Tip box will suddenly be about as attractive as Jeremy Clarkson....
I understand the that the tip can achieve 65 or there about in first where the manual can only achieve in the 50's. I take it the different in 0-60 times in the moving of the gear from 1st to 2nd in a manual.
Darren did you recieve a letter from Porsche introducing the new sports exhaust on all the carrera models? Doesnt seem to bad on retro fits either.

Regretably this tread is founded on output from a faulty abacus and having put all the beads in the right place the figures suggest that the tip is taller gearer throughout the range, which is what one would expect of a five speed v six speed. Sorry for any confusion.
Whilst I wouldn't go for tiptronic personally, the DSG sounds more interesting. However, I thought I might wait for the teething troubles to be ironed out by the first batch of owners and go for one of the second generation in 2 or 3 years time. I have a manual for delivery this september so the timing could be about right.

I was very surprised that the new 997TT was launched with Tiptronic, as this is old torque convertor technology, and I was expecting DSG.
However, it was explained to me, by a source within Porsche, that DSG was still a long way off (probably 2009MY) and, in any event, the Tiptronic option remains very important and may continue for some time on the TT, especially in the US.
This is because the 997TT is expected to attract a slightly older customer, many coming from, or also owning, a Bentley, Aston, Mercedes etc. These customers like the more sporting and youthful look of the 911 Turbo, but also want all the toys, comforts and conveniences - and for this market an auto is essential.

[quote=wrn]I am putting both a manual and a Tip 997 TT around a track on Thursday... so I'll report back!
Is that the Driving Experience half day in their cars that comes (free??)with the car? It would be interesting to hear what you think as I have one booked for the beginning of September. When I bought the 996TT a whole day out with a Porsche driving consultant came as part of the deal. Hugely worthwhile except that the track section was at MIRA where the run off is a bit rough in places and as I was in my own car I was a bit more circumspect than I might otherwise have been in their motor.
