2021 BMW M550i xDrive

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 M550i xDrive.

Transmission Automatic (S8)

The 2021 BMW M550i xDrive routes its power through an eight-speed automatic (S8) and is specified with a substantial 11.09-quart engine oil capacity using 0W-30 viscosity, while delivering EPA fuel economy of 17 city, 25 highway, and 20 combined mpg. In the model's reliability history this year is notable for a very low single owner complaint, though that complaint centers on the power train and the year carries two recalls. For researchers, that combination points to a largely quiet owner-feedback record but enough recall activity—particularly around power train concerns—to merit careful review of campaign data when assessing this model year.

Reliability & federal safety record

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

Owner complaints about the 2021 BMW M550i xDrive dominate in one area — the power train, 1 of 1 reports (100%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the power train, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the power train pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
