Dyno Run Suggests The BMW M5 Could Really Be Pushing 690bhp
Hold onto your hats, people, because the F90 BMW M5 seems to be making way, way more power than advertised.
BMW will tell you it’s good for 592bhp and 553lb ft at the crank, which is a lot. But YouTube channel IND Distribution has just put its own – standard – car on a dyno and reached figures of 625bhp and 608lb ft… at the wheels. In four-wheel drive.
If those numbers really are correct for this just-run-in F90 M5, allowing for a guesstimate drivetrain loss of 10 per cent, it would mean BMW is underestimating the M5’s figures by about 100bhp and well over 100lb ft. It would make it about as powerful as a Ferrari 488…
At 1855kg the M5 is a fair bit heavier than the 1544kg 488 GTB, but even with a 311kg deficit we have to admit we’re sceptical that the M5 can really be putting out quite that much of the good stuff…

That’s twice now BMW has made a M5 and claimed it had like 50 hp less than it actually has…
M5 vs 720 ’drag race’ incoming.
720 would win hands-down. More powerful and about 2/3rds of a ton lighter
Understating power and even speed/acceleration is something every luxury/performance car company does

Oow that’s gread 😁
How come it lost to the heavier E63 in that Carwow drag then? Either the Merc also makes far more power than advertised…or the dyno reading is wrong.
The E63 would probably make over 700 at the crank
or the E63 has a superior drivetrain
Look at the torque curve, it picks up at about 2000 and doesn’t taper off at all which is really impressive
Ahh well, you see the drag races say otherwise.
10% drivetrain loss for an AWD? What planet are you guys living on? That’s the most conservative side of drivetrain loss you can imagine. Drivetrain loss is not a rule of thumb by any means, and for an AWD car with a torque converter it should be hefty.
I love BMWs and I from what I’ve read in many places the common agreement is that German auto makers will state power figures based on how much power their engine will produce in not ideal conditions (ambient temperature, humidity, elevation).
Assuming these things is tricky and imprecise. The only way to know is removing the engine.
BMW has been advertising their cars with whp since a while so I don’t get why everyone’s so surprised about it. It’s nothing new.
Everyone talks about the underrated mercs and bmws….but have they serched for the AUDI RS6 C7 that advertised 560 and made around 600. then the newer plus model made even more than 600 advertised, it was like 600 on the wheels in 4wd
