Pretty good race. The M5 is very impressive against the RS4. They both have the same amount of power 420BHP and still the M5 gets ahead....

M5 had inside advantage on an oval course...

No no no

This is the old M5 type number E39. Standard it has 400 HP and in this version 420 HP.

You´re correct about the new M5 type E60 has standard 507 HP. Infact the push-botton-effect changes the engines powerrange from 400 HP to 507 HP and sharpens the enginerepons among several other things also.

But the car in this video is the old M5 E39.
