AC Schnitzer has also now revealed its full F90 M5 program. The main performance upgrade is their tuning kit that raises the F90's (non-Competition model) power to 690 HP / 627 LB-FT. That's a gain of 99 HP and 74 LB-FT over the factory M5. This helps the ACS F90 M5 achieve a Nurburgring lap time of 7:29.50, 9 seconds quicker than the standard F90.
Other performance upgrades include the exhaust system with valve control and KW V4 coilovers (or AC Schnitzer lower spring kit). The various aero parts available can be seen in the photos below.
