Last year, BMW unveiled the 4 Series Coupe which provoked various comments. German company AC Schnitzer, which specializes in BMW cars, has tuned two models, the 430i and M440i.

In the M440i, AC Schnitzer has installed a new stainless steel exhaust system, a sports suspension with a set of springs that lower the car by 30 mm. The BMW M440i has a 3.0-liter six-cylinder engine with 420 hp and 443 lb-ft of torque.

The 430i has a turbocharged 2.0-liter four-cylinder engine with 296 hp and 347 lb-ft (470 Nm) of torque.

Both models feature a new set of 19 or 20-inch wheels in diamond cut, gray or black.

The price of the upgrade is not known, but the five-year warranty gives some peace of mind.
