OK, based on the gear ratios given by aaronng and the tyres sizes, I have calculated the following speeds:

Manual CU2 Standard with 225/50R17 tyres.
Gear - km/h per 1000rpm - theoretical speed at 7000rpm
1st - 8.0 - 55.7
2nd - 12.7 - 89.2
3rd - 18.2 - 127.3
4th - 24.3 - 170.1
5th - 29.9 - 209.2
6th - 37.7 - 263.8 (you wish)

Manual CU2 Luxury with 235/45R18 tyres.
Gear - km/h per 1000rpm - theoretical speed at 7000rpm
1st - 8.1 - 56.7
2nd - 13.0 - 90.8
3rd - 18.5 - 129.6
4th - 24.7 - 173.2
5th - 30.4 - 213.0
6th - 38.4 - 268.5 (yeah right)

Manual CL9 Standard with 205/55R16 tyres.
Gear - km/h per 1000rpm - theoretical speed at 7000rpm
1st - 7.7* - 53.8*
2nd - 14.4 - 101.0
3rd - 20.0 - 140.3
4th - 26.4 - 185.0
5th - 32.9 - 230.2
6th - 41.3 - 288.2 (Ha!)

Manual CL9 Luxury with 225/45R17 tyres.
Gear - km/h per 1000rpm - theoretical speed at 7000rpm
1st - 7.7* - 54.0*
2nd - 14.5 - 101.4
3rd - 20.1 - 140.8
4th - 26.5 - 185.7
5th - 33.0 - 231.1
6th - 41.3 - 289.4 (Ha!)

* caused by rounding to first decimal place.

Anyone got the auto gear ratios and final drive ratio?
