When it comes to making BMWs look better and go faster, few do it better than legendary tuning house AC Schnitzer. This company is responsible for building some of the coolest tuned BMWs out there, and these days it has its hands in everything from M cars to electric models. We already know what happens when AC Schnitzer gets its hands on M models, but what about the more accessible G26 4 Series Gran Coupe? It turns out that this family-friendly coupe can be transformed into a beast with the right selection of parts.

The 4 Series Gran Coupe shares its massive grille and planted stance with the rest of the 4 Series range, but this version benefits from slinky coupe styling with the added benefit of four doors. AC Schnitzer starts with an M440i xDrive Gran Coupe, which features a turbocharged six-cylinder engine producing 382 horsepower and 369 lb-ft of torque, along with M Sport suspension and improved brakes.

The company takes this capable cruiser and fits an ECU control unit that boosts power to an impressive 414 hp and 443 lb-ft of torque, and includes cold start control and overload/overheat controls for safe operation. AC Schnitzer also offers various performance exhaust systems for the G26 Gran Coupe, our favorite being the carbon-tipped version.

Everyone who knows AC Schnitzer cars from the 1980s and 1990s knows that this company likes the in-your-face approach to styling, but the company has kept the styling elements refreshingly simple on this 4 Series Gran Coupe. The front of the car features an AC Schnitzer front splitter that integrates perfectly with the M Aerodynamics package. Wheels can make or break a car, and this 4 Series features a set of 20-inch AC Schnitzer Type AC4 wheels that feature five multi-spokes and are finished off in a menacing black. The side profile also shows off some subtle wind deflector fins behind the front fender, and at the back, there's a more aggressive lip spoiler, roof spoiler, and diffuser setup. The entire car sits about 0.8 inches lower thanks to a set of lowering springs, completing the aggressive new look.

The interior also receives some much-needed love in the form of an alloy pedal set that brightens up the footwell, a new set of shifter paddles behind the steering wheel that feature the AC Schnitzer logo, and a special keyholder that slots into the cupholder. The overall look is menacing without being too shouty, and with the added performance, makes this 4 Series a serious street weapon.

As far as pricing goes, the most affordable AC4 wheelset costs €4,390 (about $4,249 at current rates). The performance upgrade kit goes for €4,308 ($4,170) and the priciest exhaust costs €3,888 ($3,763). That's already over $12k, but it's possible to spend even more with every available option.
