ABOUT THE 2015 BMW M6 CONVERTIBLE
The 2015 BMW M6 Convertible is the soft-top version of the third-generation M6 (F13), built on the 6 Series convertible. It is powered by the S63 twin-turbocharged 4.4-litre V8 with 560 hp and 500 lb-ft (680 Nm), driving the rear wheels. This entry covers the version with the seven-speed M dual-clutch transmission; a six-speed manual was also available in the US.
Where 2015 sits
This generation of M6 arrived for 2012, and 2015 was the last model year before the 6 Series range was facelifted. For 2015 BMW offered a Competition Package that raised output to 575 hp and firmed up the suspension and steering.
Grand tourer with open-air appeal
The M6 Convertible is a heavy, high-speed luxury car rather than a lightweight sports car. Its fabric roof folds electrically, and a separate glass rear window can be raised to cut buffeting. There are four seats, though rear legroom suits children or short trips best, and the boot shrinks when the roof is stowed.
Buying one today
The S63 V8 is complex and costly to maintain. Commonly reported issues include oil consumption, coolant and oil leaks around the turbochargers in the engine’s central “hot vee”, and a need for frequent oil changes. Check the roof mechanism and drainage, and budget for expensive brakes and tyres.
Rivals
Alternatives included the Mercedes-Benz SL63 AMG, Bentley Continental GT V8 S Convertible and Maserati GranTurismo Convertible.
