AC Schnitzer ACS4 Sport


The tuning experts at AC Schnitzer have given the BMW M4 with Motorsport power a further kick of energy. Once again, the Aachen-based tuning specialists have shown that there's no upper limit to power and sporting performance. By the time the company is done, the coupe gets renamed the ACS4 Sport.


The M4 is already a potent machine with its 431-horsepower, turbocharged inline-six, but for customers willing to spend the money, more performance is always possible. AC Schnitzer's engine upgrade takes power up to 510 hp and 476 pound-feet of torque, and buyers can also add a new exhaust with carbon-fiber-surrounded tail pipes barely protruding from the rear.

The company offers two suspension kits, as well. The first lowers the BMW by 1.0-1.2 inches in front and 0.4-0.6 inches in the rear. However, for drivers who really want to scrape the ground, an adjustable racing option drops the front by 1.2-1.6 inches and the back by 1.2 inches.


AC Schnitzer's buyers also want to show off their cars' added performance, and the company is ready with a host of carbon fiber pieces. Up front, there's a new front spoiler, splitter and side flicks, and the rear is available with a diffuser, roof spoiler and fixed rear wing. A wide variety of wheels finish off the sporty look, including the brand's AC1 BiColor twin-spoke design offered in forged or standard versions.

In addition, Type VIII forged alloys, racing forged alloys and alloy rims in BiColor black, silver or anthracite, Type V forged alloys in BiColor or anthracite, and Type IV rims in BiColor black are available up to size 21 inch with corresponding tyres.
