Tuned BMW M5 Comp Drags and Rolls Modded E 63 S. It's Close But Not Close Enough. Published: 30 Jun 2023, 06:54 UTC • By: Aurel Niculescu. 20 photos. Photo: Sam CarLegion / YouTube.

So, even if it's stock, the M5 Comp sure has more than the official 617 horsepower and 553 lb-ft (750 Nm) advertised by BMW for the 4.4-liter S63 twin-turbo V8.

That’s all changed; the 2025 M5 sedan weighs in at 5390 pounds, which is about 1100 more than the outgoing M5 Comp. According to BMW’s numbers, the Touring will be an even heftier 5530 pounds.
