2021 Mini Cooper

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

Transmission Automatic (AM-S7)

The 2021 Mini Cooper pairs a 7-speed automated manual transmission (AM-S7) with fuel economy rated at 28 mpg city, 37 mpg highway, and 31 mpg combined, its engine maintained with 4.5 quarts of 0W-20 oil. Within a complaint history spanning 2001 through 2026, this model year sits comfortably in the platform's mature era—far removed from the 2005 peak of 843 complaints and trending toward the single-digit territory that would characterize 2024's record low of one complaint. For researchers, that positions the 2021 as a product of accumulated refinement rather than the early-generation teething issues that defined the model's start, suggesting a comparatively settled point in the Cooper's reliability curve.
