It's somewhat strange, the RS4 and RS6 both seem to underperform on the rollers, the S3 generally seems to overperform (results stock around 280-290bhp are seen frequently). Makes you wonder just how they work out the book BHP in the first place...
I suppose it'd need a few owners to dyno their engines to form any kind of proof.....but if it's true then they may have a case.
That said, there are a lot of variables that impact on power output. Perhaps Audi conducted their tests at optimum temp/air density etc, whereas those who drive in the real world can rarely replicate that.

I believe Audi's numbers 0-150 are better for the RS6 over the M5 so they feel the weight isnt an issue and from a Rolling start neither should the driver be.
As with any RR its a time and place thing, but when the car is running with other makes of cars on the same day, as mine did (BMW and PORK) and they are there or there abouts, even the 4WD cars it has some foundations I suggest. As I said its not something I get worried about, just find it interesting.
My car was 15bhp more powerful than the Fiat figure.
I can understand a small difference in claimed and what you get on a RR as it has to work out the flywheel figure from the wheel figure and every car has different transmission loss but for a car thats so expensive to be 100bhp is stunning. I'd be right back to Audi with some proper documented results and ask them sort it out.
I'd imagine the cars that are showing 100 (or more) bhp down on the claimed figure have some technical gremlins of their own. On a low mileage car, that's a lot to lose.
One things for sure, if a lawsuit is even remotely possible then the American owners are the most likely to have a punt at one.
Organising something like that is quite a challenge.
Interesting figures, a work colleague was given a 3L supercharged S4 when his RS4 went in for a service and he was convinced the S4 was quicker despite on paper being almost 100bhp down. Looks like the S4 assuming its up to spec might actually have had more power.
Well, the B6/7 S4 has the same engine as the RS4 - what are the figures like for it?
It must be quite insulting to think you paid all that extra money for an RS4 and it's only pumping out ~ 20bhp more than an S4 (providing the S4 figures are reliable).
Not the new one. The new S4 has a supercharged V6 IIRC.

The B6/7 S4 does not have the same engine. May share some elements but it's not the same.
