2001 Mini COOPER - ONE Hardtop — R50

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 COOPER - ONE Hardtop R50.

Engine R50

The 2001 Mini Cooper One Hardtop sits at the head of the R50 line, running the R50 engine family and carrying the "One" designation that places it as the entry-level variant in the model's range. As the most accessible configuration, it represents the base offering that the broader R50 generation grew from, paired with the compact packaging that defined the modern Mini. Across the model year's reliability record, just six owner complaints have been filed—with the Power Train accounting for the dominant share—and no recalls have been issued against it. For researchers tracing dependability, that combination of minimal complaints and a recall-free history marks the 2001 model year as a clean starting point and a useful baseline for evaluating the R50's reliability trajectory.
