It is common knowledge that air con reduces mpg but what about the power ?

Afaik, it's around 10-15 horsepower, which will cost you 0.1 to 0.15 in the 1/4...
...but the 10-15 figure was something I read years ago, so maybe they're more efficient these days.
Also, I recall reading somewhere that Mercedes automatically shut off the compressor when you apply full throttle, so this might not be a factor. Still, no harm in switching to econ mode when you want to haul ***!!

definately puts a drain on power
I can feel it in my w202, of course :p But with bigger engines, as our ML430 and S500 when I have the A/C on, I can barely tell the difference cuz the power is still up there, lol.
No prob on the 55 but yeah, it does loose a few ponies
