Rolling roads ... nice article
#1
If you can read German, go buy this months Sport Auto ... it features a test of 2 rolling roads.
If you can't ... they tested an Audi RS4 (their long termer, normaly 380 BHP).
They often get emails from readers asking why they never RR the cars in their famous Supertests ... (because manufactureres just might present them with, um, very happy cars). They used this article to explain why...
On one rolling road, the RS4 got 431 BHP, on the other 395 BHP.
The car is completely standard.
The engine was bench tested during QC at Audi when it was new, and made 376 BHP
OK, it may have opened up a little bit by running it in.
Apart from that, great info on why RR info can be so different/inconsistent, wy turbo cars are disadvantaged, etc..
PS: I could see, judging by the printout that the RR used in the 295 BHP test was probably the same as the one at Powerstation (using DIN70020 compensation).

Chins, I don't really understand why you feel you must use the mad smiley ... I was just giving some info about a good article about rolling roads, not trying to "prove a point" ... buy it, read it, draw your own conclusions.
I think it's interesting to read that the best RR fan can only produce the equivalent of 180 km/h runs, while the car is doing a (virtual) 250 km/h.
I think it's interesting to read about the different correction factors, and how they can influence the outcome.
I frankly don't give a rat's *** about who's rolling road is the most accurate ... I do see a pattern (it may be wrong) that the type of RR used by PS do seem to give lower numbers than other rolling roads.
I probably should have started a thread about my Cav whooping some ***.
FFS. Can we grow up on this bbs ?
Disgusted.
