A highlight of the 2013 Essen Motor Show->ke2128 is the TUNE IT! SAFE! car and this year, the Association of German Vehicle Tuners (VDAT) has introduced the BMW 4 Series-based ACS4 2.8i Coupe.

The Bimmer->ke178 coupe was worked on by AC Schnitzer->ke513, hence the familiar nomenclature, and comes with a steady diet of aftermarket upgrades that would make the the Police and the Federal Ministry for Transport, Construction and Road Development really proud.

It's an extensive project, just like previous TUNE IT! SAFE! models and appropriate for an event like Essen. The ACS4 2.8i Coupe comes with a number of new aero components from AC Schnitzer, including a front and rear spoiler, a rear roof spoiler, and a rear diffuser. Adding to those new items to the exterior are a new set of 21-inch alloy wheels wrapped in Hankook 245/30ZR21 Ventus S1 evo tires and an adjustable race-spec suspension that not only lowers the height of the coupe by 25 mm (0.98 inches) but also gives it improved stability in the event the police car is used for law-enforcing purposes.

For the interior, AC Schnitzer continued with its functional modifications on the 4 Series->ke3834 Coupe. None of the upgrades will blow your socks off, but for what they're worth, the new floor mats, key holder, and aluminum gear knob, foot rest, handbrake handle, and pedal set all represent upgrades in their own right.

Under the hood of this specially-prepared 4 Series Coupe, AC Schnitzer did a sizable performance bump, increasing the output of the sports car->ke506's 2.0-liter, four-cylinder turbo engine from 245 horsepower and 255 pound-feet of torque, all the way up to 294 horsepower and 310 pound-feet of torque. With these new numbers, the sports coupe can now hit 62 mph in 5.7 seconds, 50 to 112 mph in 12.7 seconds. Top speed is still limited to 155 mph, though, so that's a little disappointing.

You can just tell that these guys would love to take this 4 Series out for a spin.

Those wheels drown in all the livery, but they still look mighty fancy.

The stainless steel exhaust system will give this 4 Series that throaty growl.

The interior was redesigned for law-enforcement duties.

Not the kind of car you'd want to see on your rear-view mirror.
