My friends S8 Plus is advertised as 3.3s, I clocked it using Dragy at 3.4s. (The best time was 3.2 secs!)
Now for my M550 its advertised as 3.6s, I clocked it at 4.2 secs and the best at 4.1 secs.
I'd say dragy is pretty damn accurate!

Hmm, so it's official - N63B44T3 version installed in 20/21 M550 has either software bug or some kind of minor hardware issue that momentarily reduces power. What's confusing is that the same engine is installed in V8 versions
of X5/X6/X7/850 and none have issues. I'm at loss, seriously. Good luck to owners - I would be very pissed if my 18 M550 was doing 0-60 in 4.5s.
