I have a 2006 C2/Tiptronic with the Sport Mode button. The manual says, "The Tiptronic S switches to a sporty gear-changing map and shortens the gear shifting periods. Gear changes take place faster." [My emphasis]

What do the boldfaced portions mean, exactly? I understand what changing the map means. But what periods are shortened? And does each gear change actually happen faster, as in fewer milliseconds to effect a change from, say, 3rd to 4th gear?

I've had this car for about six months, but tomorrow will be our first time on the track together (non-competitive).

A sportier basic map is selected for the
Tiptronic Stransmission in D mode.
Automatic upshiftswhen the maximum
rpm is reached are prevented in Manual
mode (other than with a kickdown) which
improves driveability, particularly when
breaking ahead of corners. This means
that the driver can decide whether and
when to shift up a gear. Shifting times
when shifting up and down are reduced
at the same time, which makes for no-
ticeably sharper gear changes.
Automatic downshifts when braking in
D position are executed with more
emphasis on sportiness and less
emphasis on smoothness and comfort,
thereby increasing vehicle agility when
braking.

brec, I drive a Tip at the track, have been for 2 years. I never drive in auto mode...it's horrible at the track. I drive on the street and at the track in manual mode.

Driving in manual mode with the sport button on the Tip will hold the gear with out automatically upshifting if you do not have the gas pedal press past the kcik down button. This can be very helpful in certain turns at the track other wise with out the sport button on the Tip will up shift at weird times like in a turn.

I too have been driving in manual on the street.

Porsche seems to say that Sport makes shifts faster, i.e., reduces the time to get from one gear to another. I wonder why, if this speedup is available, it's not always on. Is there something less comfortable in "city" driving about faster gear changes?Do we know yet what driver controls this will have? [Wandering slightly off my own topic...] I really liked the transmission controls in my previous car better than the Tip's. The Acura coupe's automatic had a manual mode controlled from the console, either via a paddle-like forward-back (up-downshift) motion or via direct selection along a front-to-back pattern. Having the steering wheel buttons seems quite awkward in comparison; do Tip drivers never want to shift while turning?

In sport mode and useing the Tip in auto mode it does shift a little faster. In manual mode no difference.

The sport mode helps with downshifting. Try
going into a first gear turn and you will notice the time it takes to downshift
when you are not in first gear. There are places on the track
that you can shift gears with a tip that you would loose time
shifting with a clutch.
