My Sat Nav has recorded 168mph as the top speed when the limiter cut in which equates to about 175mph on the speedo. In Germany of course. Not that there's much chance on those autobahns - too much traffic, too many road works, trucks in fast lane, people pull out first and then indicate, lane hoggers don't move over. Gets worse every year.

Just returned from Frankfurt myself, my speedo was indicating something around 280/290kmh on a clear section of autobahn. Very nice.

... speed limits become more and more popular!
Hope we get better road conditions soon, but you know: Germany is poor!

What is the Vmax of the RS4 if you would take the 250KMH limiter off?

Unmodified: 283km/h, I think!

The absolute max speed is limited to the final gear ratio in conjunction with the rev limiter (not speed limiter).

The latest Audi Driver mag has the stats on the final drive ratio and speed to revs. In theory if you had enough power and from memory I think it works out at 187mph at 7000rpm. But I'd need to check that.

1km/hr = 0.621miles/hr - 283km/hr only converts to 175.8miles/hr. I shouldn't say ONLY!!

When originally tested by the motoring hacks, I think they claimed to have got 177 mph with aid of sat nav. They were surprised because they had been told that car was limited to 155 mph, I know my speedo reads 165 when on limiter, theres was reading nearer 190 from memory.................

181 is where im at offically with sat nav, showing well into the 190s on the clock, but thats witha unmapped 520 MTM conversion, now its been re-mappped by Peter Link at MTM, so who know what i might see, in three weeks time

My car is limeted to 279 kph or 173.36 mph thats when the limeter kicks in.

But, I forgot to tell you guys that I´m running 255/40 R18 thats 4% more in diameter than the stock 255/35 R18, so I was actually going 290 kph.
