AC Schnitzer Turns G80 BMW M3 Into Their Most Powerful 3-Series Ever

AC Schnitzer has revealed a suite of upgrades it has developed for the G80 BMW M3 Competition. Its improvements add power, aero elements, suspension components and should get you moving in a hurry – both to the nearest distribution center and away from it.

First and foremost, the tuner has passed its magic wand over the M3 Competition’s straight-six engine to raise power from 503 hp (510 PS/375 kW) and 479 lb-ft (650 Nm) of torque all the way up to 582 hp (590 PS/434 kW) and 553 lb-ft (750 Nm) of torque. All of which also comes with a warranty of up to four years.

To hint at the extra power, AC Schnitzer has also added a sport exhaust system with two carbon “Sport” tailpipes on either side of the rear. Together they bring improved flow and better sound qualities at the same time.

The M3 Competition can also be lowered 15-20mm (0.5-078 inches) at the front. The suspension spring kit with RS coilovers makes both compression and rebound adjustable.

AC Schnitzer has been careful not to create a needlessly stiff suspension and says its motto has been “better fast than hard,” which is quite the mantra. It has led to a suspension that the company says has “good-natured load change reactions and gentle understeer at the limits.”

A front-splitter (which can be installed with no need for painting) increases downforce by as much as 40 kg (88 lbs) at 200 km/h (124 mph). Aero continues down the sides of the M3 with a four-piece deflector set for the front fenders, which are complemented by design elements on the hood.

At the back, meanwhile, a roof spoiler adds another 20 kg (44 lbs) of downforce. The combination of a rear diffusor, a new Carbon “Racing” rear wing that has a gurney flap makes another 70 kg (154 lbs) of downforce to keep you good and planted through the corners.

Keeping unsprung weight low, meanwhile, are the AC3 Lightweight Forged Wheels that are available in Silver/Anthracite or Anthracite/Silver and measure 10.0 J x 20 inches. The wheels can be fitted with 285/30 R 20 tires at the front and 295/30 R 20 tires at the back.

Inside, AC Schnitzer has designed its own steering wheel made of fine black Nappa leather and black Alcantara. Recessed grips offer a more comfortable place for the driver to rest their thumbs.

The tuner also offers bigger paddle shifters to make them easier to find. Aluminum pedals and footrests are joined by an aluminum keyholder and cover for the iDrive Controller to make the interior look sportier.
