M Performance accessories are developed by the engineers at BMW M and are held to the same standard as parts going on the division’s dedicated M cars. Importantly, these new M Performance accessories for the 4-Series hint at the styling we can expect on the high-performance M4, which is tipped to debut at the 2014 Detroit Auto Show next January.
For those looking to lift performance of the standard 4-Series, the M Performance catalog includes items such as a proper mechanical limited-slip differential, lowered suspension, uprated brakes and a sports exhaust systems. As the photos confirm, chunky 20-inch alloys and an aggressive body kit will also be offered.
Cosmetic items, for both the exterior and cabin, include black highlights for the kidney grille and new fender vents, M Performance decals, Alcantara and carbon fiber interior trim, stainless steel pedal covers and sporty bucket seats. We can also see that BMW will make its tech-laden M Performance sports steering wheel available on the latest 4-Series.
British outlet Autocar is reporting that M Performance power upgrades will also be offered, at least overseas. For the 428i, a kit is available that’s said to boosts output by 29 horsepower to a new peak of 269 horsepower, while for the 435i a similar kit lifts output by a claimed 36 horsepower to a new peak of 336 horsepower. The kits consist of exhaust tuning and ECU tweaks.
Pricing and availability in the U.S. should be announced shortly.
