The fifth concept of this initiative was tuned by BMW tuner specialist AC Schnitzer. The base car was a BMW 123d coupe provided by the German automaker. Most of the aftermarket parts the car got were supplied by Aachen-based BMW tuning specialist AC Schnitzer.
The project was named “ACS1 2.3d“ and it is meant to show that safe tuning is far from boring. AC Schnitzer has upgraded the 2.3 D engine to 241 HP (177 kW) and 480 Nm. The project car, which was turned into a police car, has a 6-speed automatic transmission. With the recent modifications, the car can accelerate from 0 to 100 km/h in 6.7 seconds, so running away from the cops just got a little more complicated.
ACS1 2.3d is equipped with the latest AC Schnitzer wheels Type IV BiColor, fitted with tires from TUNE IT! SAFE! main sponsor Hankook. The car’s handling was improved with the help of a sport suspension which lowers the BMW by 30 mm.
The exterior did not remain untouched either. The car got a two-piece front spoiler, rear skirt insert, rear wing and rear roof spoiler, some "LEDayFlex“ modern daytime running lights from Hella, and optimum rearward vision with the use of AC Schnitzer "New Generation" sports mirrors.
The concept car will not be brought into use. However it will make an important contribution into combating illegal, unsafe tuning and counterfeiting. The AC Schnitzer "ACS1 2.3d Coupe“ will be on display for the first time at the Essen Motor Show.
