AC-Schnitzer Enhances the BMW M440i

The fresh new redesign of the BMW M4 has already seen a lot of controversies. The German company has received a mixed response concerning the front grille. Some like the large size, while others argue against it. BMW believes that the new design is the company’s first step into the future.


In such cases, enthusiasts look to the aftermarket, hoping that tuners and coachbuilders do something different to improve the appearance and performance of the car. AC-Schnitzer has done just that with the BMW M440i. The company has offered a few tweaks to enhance the car’s aesthetics.

Updates include the AC Schnitzer front spoiler, front splitter, side skirts, a rear roof spoiler, rear skirt protection foil, and the tuner’s badges spread throughout the vehicle. The brand also offers a set of new wheels for those who are interested in different designs.


Concerning performance, AC Schnitzer has tuned the BMW M4 engine to produce 420 hp and 442 lb-ft of torque. The regular powertrain is only good for 374 hp and 369 lb-ft of torque. In number terms, that is a 36 hp increase and a more than generous addition to the torque range. The German tuner can also tweak the BMW 430i and increase its power from 258 hp to 300 hp. 

AC Schnitzer also offers a new stainless steel exhaust system with various tip designs. Consumers can choose from carbon fiber or black chrome tips.

There are no reports with regards to the price, but it is natural for tuned vehicles to cost well above the top-of-the-line variant.
