AC Schnitzer unveils 510hp BMW M4 Coupe at 2015 Geneva show
AC Schnitzer’s upgraded BMW M4 Coupe makes its public debut at Geneva, featuring 510hp, a full coilover suspension kit and distinctive carbon aerodynamic parts.
AC Schnitzer presented its take on the BMW M4 Coupe at the 2015 Geneva Motor Show, revealing a package that lifts the coupé’s output to 510hp and introduces a suite of chassis and aerodynamic upgrades. The car was displayed on the show floor with a full set of Schnitzer’s signature carbon fibre parts and a lowered stance.
Power and performance upgrades
The biggest mechanical change comes under the bonnet. AC Schnitzer’s package includes an additional control unit for the M4’s turbocharged six-cylinder engine, increasing output from the standard 431hp to 510hp and torque from 550Nm to 645Nm. That puts the tuned M4 well clear of the regular car’s figures, and above the standard M3 and M4 Competition models of the same era.
The exhaust system is also reworked, with a race exhaust featuring a valve control system to let owners adjust the volume and tone. This gives the car a more aggressive soundtrack to match the performance increase.
Chassis and aerodynamic changes
AC Schnitzer’s coilover suspension kit is fully adjustable and can lower the M4’s front end by 30 to 40mm, and the rear by 30mm. For buyers wanting a less extreme drop, a spring kit will be available as standard, offering a reduction of 25 to 30mm at the front and 10 to 15mm at the rear. These changes are aimed at improving both the car’s stance and its handling on road or track.
- Carbon rear wing in two versions: road and racetrack
- Carbon fibre rear diffuser
- Roof spoiler with carbon mirror caps
The carbon rear wing is available in two versions, one for road use and a larger, more aggressive variant for track driving. Both are designed to increase downforce at speed. The rear diffuser and roof spoiler further add to the car’s aerodynamic profile, while carbon mirror caps round out the exterior changes.
Market positioning and availability
AC Schnitzer’s upgrades are aimed at BMW M4 buyers looking for more power and sharper dynamics without moving to a full race car. The Geneva show car demonstrates the company’s approach to both street and track performance, with the option for buyers to tailor the aerodynamic kit to their needs.
Pricing for the full package had not been announced at the time of the Geneva debut. The car’s public reveal drew attention from both BMW enthusiasts and tuning specialists, standing out among the performance-focused debuts at the 2015 Geneva Motor Show.
