Anyone know what the gear ratio is on the Tip? Has those numbers even come out yet?
For example can you hit 60mph in 1st gear? Information like that....
Thanks in advance!

anyone know if you can hit 62mph in 1st gear with TIP?
Only if the car had an optional "low end TQ" OHV 7 Liter like a C6 Z06 , which hits 62 in first at the rev limiter!

997TT TIPTRONIC:
gear km/h (mph)
1. 75 (47)
2. 124 (77)
3. 192 (120)
4. 271 (169)
5. 326 (204)
there must be a mistake in the manual's data. because with an overall gear ratio of 3,44 and a sixth gear with 0,79 and 6600rpm redline, the manual car would reach its redline at 304,7 km/h or 190,4mph.

First of all thank you RC for posting this great info. But I never really understood 100% exactly what those numbers meant.
1. 3,59 1. 3,82
2. 2,19 2. 2,14
3. 1,41 3. 1,48
4. 1,00 4. 1,18
5. 0,83 5. 0,97
Manual 6. 0,79
Can someone give me a QUICK explanation so I can finally understand... Thanks in advance guys!!!

Basically, you need the gear ratio, one from the above, take the final drive ratio, the RPM and the tyre circumference in cm. Multiply them all. From that you will get x cm/min, which you can then convert into km/h or mph. Now I know there mist be an easier way, but I don't know it. Maybe if you made the tyre circumference in kilometers (0.002 km ) and multiplied the RPM by 60 at the beginning. So basically:
(Gear ratio) × (Final drive) × (RPM × 60) × (tyre circumference in kilometers) = speed in gear

I just took the available data from the technical description, it may be wrong but this is all I have.

Gear Ratios 997 Turbo:
TIPTRONIC S MANUAL
1. 3,59 1. 3,82
2. 2,19 2. 2,14
3. 1,41 3. 1,48
4. 1,00 4. 1,18
5. 0,83 5. 0,97
Manual 6. 0,79
Overall gear ratio:
Tiptronic: 3,06
Manual: 3,44
For comparison, 996 Turbo:
TIPTRONIC S MANUAL
1. 3,59 1. 3,82
2. 2,19 2. 2,05
3. 1,41 3. 1,41
4. 1,00 4. 1,12
5. 0,83 5. 0,92
Manual 6. 0,75
The 997 Turbo Manual gear ratio is in each gear (exception: first gear) shorter than on the previous 996 Turbo model. So here goes the conspiracy of a longer gear ratio to make the manual version accelerate slowlier than Tiptronic by purpose.

As you may have noticed, the 997 Turbo Tiptronic S gear ratio is the same as in the previous 996 Turbo model.

not exactly.
maximum rpm / 60 * tyre circumference in meters * 3,6 / [(Gear ratio) × (Final drive)] = km/h in gear at maximum rpm

Al - The 997 Turbo 6-speed and the 996 Turbo 6-speed have the same overall gear ratio in 1st gear.
