Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 Cooper S Roadster.
Transmission Automatic (S6)
The 2011 Mini Cooper S Roadster, built on the R59 platform, uses 4.4 quarts of 5W-30 oil and pairs its engine with an automatic (S6) transmission, achieving EPA ratings of 25 city, 33 highway, and 28 combined mpg. In the model’s complaint history covering 2004 to 2025, the 2011 model year falls between the highest-complaint year of 2004 (529 complaints) and the lowest of 2022 (1 complaint), placing it in a middle range of reported issues for the line. This suggests that while the 2011 Roadster is not among the most problematic years, it also does not share the near-zero complaint record of later models.
