📖BMW M6 Gran Coupé F06M LCI (2014-2018): pinnacle four-door M elegance with up to 600 hp Competition firepower

BMW M6 Gran Coupé (F06M LCI, facelift 2014) (2014-2018)

The late-2014 LCI facelift of the BMW M6 Gran Coupé F06M brought refreshed adaptive LED headlights, revised front kidney grilles, updated cabin trim, and optional Competition Packages raising output to 575 hp and eventually 600 hp. It combined executive luxury with blistering straight-line performance. Maintaining this heavyweight four-door grand tourer requires proactive BMW M6 maintenance, centered around powertrain cooling and transmission servicing.

The twin-turbo S63TU engine demands regular inspections of its auxiliary cooling circuit, specifically the plastic coolant fittings and electric water pumps that cool the turbos after engine shutdown. Power is directed through the rapid-shifting seven-speed M DCT dual-clutch transmission and the electronically modulated M differential. Regular fluid changes are crucial to prevent transmission judder.

Chassis wear is influenced by the car’s two-tonne mass; suspension bushings, front ball joints, and brake rotors endure heavy loads. Vehicles optioned with M Carbon Ceramic Brakes require inspection for surface flaking and pad wear.
