    What gear do should the S3 be in when run on the rolling road?

    Hi Barry,

    This is really strange, you were at the AMD rolling road day right? well all the other s3 i could tell were run in 4th gear like you say. But for some reason they ran my car in 5th gear. I do not know the reason why but i'm keen to find out. Also you may remember that my S3 had the lowest output in comparison to all the others.

    What do you think?

    The car ashould be run in the gear that gives closest to 1:1 ratio of wheel speed to engine speed - which is normally 4th.

    I have a S3 road test here from Autocar and they list the gear ratios of the S3 box like this.

    1st - 3.42
    2nd - 2.11
    3rd - 1.43
    4th - 1.09 (final drive of 4.2 for 1st to 4th)
    5th - 1.10
    6th - 0.91 (final drive of 3.32 for 5th and 6th)

    Anyone know why the 5th and 6th has a different final drive than 1st to 4th, all the other road tests ive looked at all gears have the same final drive. e.g. Impreza WRX 3.9, Clio 172 4.19, civic type r 4.76 etc etc

    Mark, I got this from audiworld: At least it shows the ratios you posted are possible. I'm not a mechanic so I dont know if higher final drive gives economy or performance. /ubbthreads/images/graemlins/confused.gif I'd guess economy.

    The 6-speed gearbox fitted as standard to the Audi S3 allows the driver to make optimum use of its turbocharged engine's power. Gear lever travel is short and precise: a positive invitation to make fast gear changes. The gearbox uses the three-shaft design familiar from the Audi TT quattro. The third shaft is used for 5th and 6th gear and reverse and has a higher final drive ratio. The gearbox is compact, has an ultra-light magnesium casing and can transmit high torques at low engine speeds. The gears are selected by cable to prevent troublesome vibration from being transmitted to the gear lever or the car's interior.
