probably 3.42s in the rear, but you need to know tire size too.

If it's an auto and you turn 62 @2000 You should turn 2300 at 70, which is 3.73s.

tire size 245/50/16

i turn 100 km/h @ 2000 rpm

Your automatic will either be 2.73 or 3.23.

Look on your door panel for your list of codes.

GU3 = 2.73
GU5 = 3.23

Generally speaking the SS and WS6's had the better gear by default but the Formulas and Z28's could have it as an option.

With my car (3.23) I turn 1500 @ 50mph with a stock diameter tire.

Its 3.42s on a stock tire size.

Speed (in mph) at 2000 rpm for an A4 by rear gear, assuming stock tire size and no PWM slip:

2.73: 79
3.23: 67
3.42: 63
3.73: 58
4.10: 53

Throw in a little PWM slip and 62 mph at 2000 is dead on for 3.42s. Probably switched gears by the previous owner.

Again, it's 3.73s
