Standard car is rated at 560 PS at the crank. Comp package pushes that to 575.

This ~511 to the wheels. Which means about 600 at the crank.

I think it's about 585hp at the crank because the drivetrain losses are usually about 15% for a RWD car.

Anyway very good and more than the BMW factory claims

A lot of Torque / Nm by the way.

Drivetrain losses are not calculated in standard hp figures but in percentage.
And ofcourse AWD has a higher percentage of drivetrain losses.

The M5 of M-Bitious had also 15% losses. However some tuners tune up they're figures and fill in manualy 20% or maybe more. So you THINK you have more crank HP. That's why RWHP is so important.

I actually believe rear wheel drive loss to only be about 10% not more.

I would like to see someone (like Dinan) who has put their engine on a engine dyno to then dyno at the wheels at give us some better info as to drivetrain loss. Otherwise, we are just speculating.
