I have perused the resource threads compiled by S70 Driver, but have been unable to find some hard specs, eg transmission and differential ratios for our cars. Do any of you guys have such data?
Thanks - David.

Well that would be an M56H which has a final drive ratio of 4.00

1st 3.07
2nd 1.77
3rd 1.19
4th .87
5th .7

Hope that helps

Thank you for your response 300+. I assume the the axel ratio is 4:1 and fifth gear is .70 which gives the 850 five speed a final drive ratio of 2.80:1, right?
Thanks - David.

Yep, that's it.
