Is there reduced power before break-in service?
I've searched the forums and I found many opinions which run the gamut on this question. Have we reached a conclusion?
I'm trying to understand whether the M5 has reduced power before the first break-in service is performed. Normally I would have scoffed if someone suggested this but I've spent a lot of time in a 2014 E63 AMG and now in an M5 with < 700 miles and the M5 feels substantially weaker than the E63 felt.
I haven't redlined the M5 or even taken it past 5000 rpm but I can say it feels substantially weaker than the E63 at high throttle openings. The acceleration in the E63 was, to put it mildly, brutal. The M5 seems merely brisk.
Given that all the magazines which test this car observe them trapping within a mph or so of each other, I don't understand why this car would feel slower than the E63 so I am wondering about a break-in service and whether that changes things.
Thoughts?
