AMS Performance presents its performance increase for the current BMW M5 F10 and inspires with 643PS and brute 821NM torque. The car was also equipped with 90mm downpipes as well as an Eisenmann sports exhaust system and a Group-M airbox system. It can go that fast and the BMW M5 is on par with the upcoming CTS-V (which can of course also be tuned).
