Default Axle Ratios

I just bought a 2000 auto.
How can I tell the axel ratio?
It doesnt seem as quick as my m6 TA.
Is there somewhere I can check on the vin?

Assuming it's stock:

Look inside your glovebox at the list of codes. If you see G90 then you have 2.73; if you see G92 then you have the 3.15.

If you can't find the code then put the car in 3rd gear on the highway at 75 mph. Take the tach reading and divide by 1000:

3150 rpm = 3.15
2730 rpm = 2.73

Crash...

And let me be the first to welcome you the the Forum. You'll love it here, but be forewarned: mod fever is rampant around here and it's highly contagious. :cheers:

Thanks for the reply and welcome!
I think Ill try the highway method first, its more fun while the car is still new to me.

As far as modding Ill leave that for the TA, Ok maybe a nitrous kit!

On A4 cars in drive, with the 2.73, 2000 RPM's is 80 mph. On 3.15 cars, 2000 RPM's is 70 mph.
