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.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2015 BMW M6 sits at a low point in the generation’s complaint curve, registering zero complaints—the fewest of any year listed—while its recall count (2) is modestly above the 20092010 baseline but below the spike in 2013‑2014. Across the span, complaints dropped from a high of 7 in 2006‑2007 to near‑zero by 2015, then rose slightly to 4 in 2016, indicating a generally improving trend that temporarily plateaued. Technical Service Bulletins (TSBs) have been on a steady decline since the 2013 peak of 354, falling to 266 in 2015 and continuing downward, suggesting fewer recurring service issues. Although the data shows one crash‑related and one fire‑related complaint for 2015, the root causes are not specified. Overall, the 2015 model appears to be a relatively reliable year within the generation and can be considered a good year to buy, provided standard pre‑purchase inspections are performed.
