I'd guess around 2400.

The one that I test drove today ran just a hair shy of 2500 at 80 mph(by the way they are going to call me in the morning with the financing). :party:

What are you A4 Goats out there running for RPMs on the highway? (around 70-75 mph)

Just curious...
UltimateGTO.com had an online "Load Driveline Data into Top Speed Calculator" that I found exactly one year ago today. I couldn't find it today, but didn't try too hard, either. I was interested in learning the engine speeds in the A4 v. M6 in top gear at selected highway speeds. Here are some statistics I downloaded last year:

At 55 mph A4 rpm in 4th gear = 1,740
M6 rpm in 6th gear = 1,435

At 65 mph A4 rpm in 4th gear = 2,060
M6 rpm in 6th gear = 1,690

At 75 mph A4 rpm in 4th gear = 2,375
M6 rpm in 6th gear = 1,940

At 155 mph A4 rpm in 4th gear = 4,910
M6 rpm ub 6th gear = 4,000*
*This may be theoretical, I don't know if you can hit 155 in 6th.
:cheers
