Island Maser

Just curious if anyone has found the top end of this car with the speed limiter removed and stock- no tune. The car jumps to 155 really fast until big brother shuts down the fun. Pulling really hard to that point and it sure seems it had a lot more to go. I am thinking 185 ish is probably about right. I need to run some numbers though a speed calculator to see what it thinks it would be.

Many people don't realize that the right tires are needed as well for high speeds. My A6 came with H rated tires which matches the governed top speed of 130 MPH. V or Z or even W or Y tires need to be fitted on cars that are going to be driven without a governed speed - you should know what the top speed is to be sure that your tires can handle it. If you hit speeds in excess of what your tires are made for it can have a disasterous result.

I know that the guys at 5th Gear in the UK took an S7 that was "limited" to 155 to a measured 166 before they ran out of runway. That was with 4 people in the car!

Audi says that it will do "close to 190 mph" with the limiter removed.

I would believe it too

I think I read somewhere that the factory speed limiter is either 130 or 155 depending upon what tire/wheel package the car is delivered with... all weather tires get you a lower speed limit.

Somewhere on Youtube is a video of a superbike running 300KPH (180MPH) on the autobahn. After a couple of minutes he pulls over from the left lane and a few seconds later an S6 (RS6?) comes blowing past him.
