AC Schnitzer has released its new tuning program for the G22-generation of the BMW 4 Series Coupe. A slew of aerodynamic panels is part of the new tuning package. When installed, they make the 4 Series look sportier and more aggressive-looking than it already is. Engine upgrade programs are also available for the 420i, 430i, and M440i xDrive variants of the 4 Series. No word yet on pricing, but the cost will depend on the kind of upgrades that you get for your 4 Series Coupe.

The G22-generation BMW 4 Series Coupe gets a more aggressive look thanks to AC Schnitzer. A new front spoiler lip is one of the big aerodynamic additions to 4 Series models equipped with the German automaker’s M Performance package. More pronounced side skirts are also included in the package, and there’s a new roof spoiler at the back.

A slate of lightweight alloy wheel options is also available in various sizes. Sets of 19- and 20-inch wheels are available and prospective customers also have the choice to pair the wheels with tires from different well-known tire brands. Continental, Michelin, and Hankook are among the tire brands that customers can choose from. Interior upgrades, however, are limited to the usual pedal covers, aluminum shift paddles, footrests, and a key holder.

AC Schnitzer's engine upgrade program for the 4 Series is available for different variants of the 4 Series Coupe. The 2.0-liter turbocharged four-cylinder B48 engine in the 4 Series 420i produces 224 horsepower and 265 pound-feet of torque courtesy of AC Schnitzer’s engine software program. That’s a modest increase from the engine’s standard output of 184 horsepower and 221 pound-feet of torque.

AC Schnitzer also raised the power figures in the same B48 engine powering the 4 Series 430i. From the engine’s standard output of 258 horsepower and 295 pound-feet of torque, the German tuner’s program can coax 300 horsepower and 346 pound-feet of torque.

Then there’s the 3.0-liter turbocharged B58 inline-six-cylinder engine found under the hood of the BMW 4 Series M440i xDrive. Post AC Schnitzer’s tinkering, the engine now produces 400 horsepower and 442 pound-feet of torque, an increase of 18 horsepower and 73 pound-feet of torque from the engine’s standard output of 382 horsepower and 369 pound-feet of torque.

AC Schnitzer didn’t mention performance times, but with these modifications, the 420i, 430i, and M440i xDrive can accelerate to 60 mph faster than BMW’s claimed times of 7.5 seconds, 5.5 seconds, and 4.3 seconds, respectively. The top speed on all three versions of the 4 Series Coupe should, however, remain at the capped 155 mph.

Final Thoughts

There's a reason AC Schnitzer is regarded as one of the best BMW tuners in the aftermarket business. The tuner knows how to strike a balance between sections of a proper upgrade. Everything is meticulously prepared and developed so that no piece of the package is more important than the other. We see that in the tuner's new kit for the 4 Series Coupe.
