2015 BMW M6
Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 M6.
Transmission Automatic (AM-S7)
The 2015 BMW M6 is a high-output grand tourer channeling power through a seven-speed M dual-clutch automatic (AM-S7), with a 9.0-quart engine oil capacity specified for 0W-30, 0W-40, or 5W-30 viscosities. EPA fuel economy ratings of 14 city / 20 highway / 16 combined mpg underscore the powertrain's performance focus, and the model's NHTSA footprint is modest at 9 owner complaints and 1 recall, with engine-related issues leading the list. Placed against the 2006–2019 M6 complaint history — which peaks at 7 in 2006 and bottoms out at 1 in 2017 — the 2015 lands in the quieter portion of the range, marking it as a relatively dependable year in a nameplate with a noticeably uneven reliability arc.
