The BMW M5 is a high-performance variant of the BMW 5 Series marketed under the BMW M sub-brand. It is considered an iconic vehicle in the sports saloon category. The first M5 model was hand-built beginning in late 1984 on the E28 535i chassis with a modified engine from the M1 that made it the fastest production saloon at the time. M5 models have been produced for every generation of the 5 Series since 1984, with occasional gaps in production (1995 to 1998, 2023 to 2024). Official website: BMW M

I guess the obvious question now is how does it compare to its peers/competitors ?
I think you accidentally wrote V10 instead of F10
Freudian slip.
13hp over stock..i guess they are playing the Nissan GT-R game
Nah, all bmw's have that a bit more power at the crank. Their claims are always very conservative

721 NM would be 41 NM more than claimed. That's quite a lot. But it would explain the good acceleration times on par with the on paper much torquier E63 PP. Although 444hp at the wheels is not 574 hp in my mind. Even if you use a quite high drive train loss ratio of 18% it's still nowhere close to 574 hp.
With 18% it would be 524 hp. With 20% it would be 533hp. Given the fact that those cars are naturally dyno unfriendly (electronics, trans, etc. ) like the old E63, I say they're exactly at 560 hp, plus minus a little. I remember running an E63 with the old 6.2L at the shop and man it didn't put out good numbers at all (424 rwhp), yet still ran 12.54 so all the horses were there

Without any other information about this car, how would you know it's "exactly at 560 hp" vs 574? These kinds of dynos almost always seem to record low numbers compared to Dynojet dynos (which, as far as I know, won't give you an estimated drivetrain loss figure as the Maha dyno does).721 NM would be 41 NM more than claimed.

On the one hand, I'm a bit wary of dynos that correct for ambient conditions as this one does, but on the other hand, the oil temp is curiously low at 25 degrees C (2deg less than ambient). Maybe there's a correction there for the intake temp which seems high (51 deg C), but for it to hit 553 hp uncorrected, with low miles and what appears to be low oil temps indicates a pretty strong engine.

Just see this, as confirmation, that the car is probably giving what BMW is promising as these dynos are quite far from an exact science. Everything plays into the result you see. Had they done 5 runs and posted the results, we would have gotten 5 different numbers. Only thing that matters in reality is when the M5 is placed next to it's competitors and the loud pedal gets floored. So far the car has seem very capable in these situations.
Peak dyno numbers are just for bragging rights.

Putting a gauge on how much crank HP the RWD HP from a dyno provides is a guessing game. 444 RWHP is quite underwhelming in this case and in my opinion would render a RWD Auto car with actually LESS than the M5's 560 crank HP claims.
However, this is why Dyno's are usually just for fun. If you told me that the M5 weighs over 4,500 lbs and puts out 444 RWHP, I'd think that it's fast, but nothing extraordinary. The M5 defies these statistics by putting out much more impressive actual track performance than any of these stats added together suggest. That's what really matters.

According to the guy that chipped the Cayenne that is exactly what dynoing is, he uses it solely for the improvements before and after to see that what he's doing is beneficial instead of how much the car is actually putting down.

BMW M GmbH, formerly known as BMW Motorsport GmbH, is a subsidiary of
BMW AG that manufactures high-performance luxury cars. BMW M ("M" for "motorsport")
was initially created to facilitate BMW's racing program, which was very successful
in the 1960s and 1970s. As time passed, BMW M began to supplement BMW's vehicle
portfolio with specially modified higher trim models, for which they are now most
known by the general public. These M-badged cars traditionally include modified engines,
transmissions, suspensions, interior trims, aerodynamics, and exterior modifications
to set them apart from their counterparts. All M models are tested and tuned at BMW's
private facility at the Nürburgring racing circuit in Germany.
