Here is a BMW 428i from the “tune it safe” program with AC Schnitzer parts on display at the BMW Welt museum. Under the hood, AC Schnitzer has modified the standard BMW 428i Coupe to now deliver 294 hp and 420 Nm of torque. Consequently, the AC Schnitzer ACS4 2.8i Coupe can reach 100 km/h from a standstill in just 5.7 seconds. The ACS4 2.8i Coupe then includes a new stainless steel sports exhaust system with chromed tailpipes.
