One of its interesting creations is the police package the company made for the 1-Series. It debuted at the Essen Motor Show in Germany as part of the “TUNE IT! SAFE!” initiative. The latest is its tuning package for the new 5-Series.

The changes to the body are subtle – this is a tuning package for those who don’t want to mess with the BMW formula too much.

However, there are new wheels and a there’s a body package that includes with a new front fascia, a chromed grille, side skirts, roof and trunk spoilers, and a rear apron with diffuser.

Changes to the suspension consist of a lowering by 25 mm via stiffer springs and up front there is a new 8-piston caliper brake system.

AC Schnitzer has also bumped up the power, and it is choosing to focus on the diesel range. The boost in power is currently available for the 530d and its straight-six turbo diesel.

AC’s modifications take the engine from 245 horsepower to 286 hp. The company says power boosts the rest of the diesel 5-Series lineup is coming as well.

The interior has the option of black carbon fiber with silver accents, as well as an aluminum foot rest, pedals, iDrive controller and gear shift knob in leather and aluminum.

The package is available immediately. An interesting fact about AC Schnitzer is that Aachen, Germany, where it is headquartered, has a license plate code of AC . Hence the double “AC” designations in their license plates.

Here in the United States, the Crown Victoria is the most prevalent model, with a smattering of Dodge Chargers thrown in for good measure.

Chevrolet has taken aim at the market with a police-only Chevrolet Caprice model. In Germany, high-performance models have to be used, especially when patrolling high-speed corridors like the Autobahn.

The Essen Motor Show in Germany displays a specially-outfitted police car model each year, as part of the “TUNE IT! SAFE!” initiative. This years model used is a BMW 123d donated by BMW and modified by AC Schnitzer.

This car has a lot of performance-oriented changes that include boosting power from the standard car’s 204 horsepower by output to 241 horsepower and 354 pound-feet of torque. The 123d has also been lowered by 30 millimeters, and there is a raft of other, more visible changes, like a front splitter, rear spoiler, and a bigger wheel and tire package.

When you’re chasing the bad guys, you’ve got to be firmly in your seat, right? AC also fitted the car with two racing seats and included changes like carbon fiber trim, along with a new iDrive controller knob that matches the wheel design.

The AC Schnitzer 123d is just a concept (where’s the area to throw criminals at in cars like this?) and is the fifth concept car under the Association of German Car Tuners (VDAT) ”TUNE IT! SAFE!” initiative.
