Proof that CLS/E 55 perform above spec.
See this...

So they say there is a 5% drivetrain power loss and a 8% drivetrain torque loss... This efficiency of the drivetrain is unheard of ... the engine is producing more power than what the manufacturer states. Period.
By example the C55 has this chart
http://www.rri.se/popup/performanceg...p?ChartsID=607
and has 10% and 11% loss respectively - even this is quite good.
The M5 comes in as follows ....
http://www.rri.se/popup/performanceg...p?ChartsID=153
7% and 9% respectively ... so maybe even that motor is underrated...?
Any thoughts ??? - great database on this website....
EDIT : Think I misread this ... the data is the rated output adjusted for drivetrain loss ... I think....!!!?????

by their dyno, it looks like most cars are overrated by the facotry.... even the 2006 Z06, which they say is only making 475HP..... even though Chevrolet stated the Z06 is "certified" at 505HP by the new standardized SAE testing standards that the manufacturers must comply with......

Maybe drive train assumptions are out - the Golf GTI is the only one I have found that is very close to advertised spec....
Its good to note though that the CLS55 is one of the better results.
I like the standardised system they are trying to adopt ... makes good sense.

According to Page 7 of Part 2 below - the reported HP is WHP unadjusted for driveline loss....
Perhaps someone can verify this ????

The peak HP numbers for the CLS/E are at 6100 RPM, so they're probably using third gear for the measurement to avoid the speed limiter. I suspect that their inflated wheel HP & torque numbers contain a gear ratio adjustment factor.
