The BMW Z4 AC Schnitzer ACS4 is a remarkable vehicle that combines the best of German engineering with the expertise of AC Schnitzer, a renowned tuning company. This model is based on the top model in the series, the BMW Z4 M40i, and it brings a new level of performance and style to the Z4 lineup.

The ACS4 is not just a regular Z4; it’s a car that has been meticulously tuned and modified to deliver superior performance. The power of the regular Z4 has been increased to a smooth 400 hp and 600 Nm, thanks to reworked engine electronics and a sports rear silencer with exhaust trims in the “Sport Carbon” or “Sport Black” versions. This gives the car a louder, more appealing voice and ensures that every last one of the claimed horses is there.

The ACS4 also features a new coilover suspension, which provides a more consistent weight and more realistic feel through the steering. There’s no shortage of grip, either, thanks to the Conti Force Contacts – Continental’s first trackday tyre. The ACS4 also features Schnitzer’s brake kit, with bigger discs front and rear and six- and four-pot calipers respectively.
