I'm new here, just got my 55-plate S4 auto last week. After a lot of searching, I chose it over an M3 E46, R32, and an older 911. Very happy indeed (apart from mpg!) but...
Peak power is 340bhp at 7,000rpm. Red line is 7,000. However, the car will not rev higher than 6,800. It changes up. In sport, kick-down or manual, it always changes up around 6,700-6,800 no matter what. Therefore I am not getting 340bhp at all. Never.
Put it another way, Audi might as well say it produces 400bhp at 8,000 but since it cannot rev that high, you won't be seeing it.
My question is, are other folks' S4 autos the same? What about manual cars? Do they rev to the red line, or even to the limiter which I would expect to be 7,200rpm or thereabouts.
This is all further confused by the handbook which has various illustrations with the red line at either 6,500, or 6,700 depending on which picture you look at. Yet the sales brochure produced when the car was new has a bhp/torque graph that clearly runs up to 7,200...
Can other owners shed any light on this?
