The Cooper is now available with four doors. Engine choices include three- and four-cylinder turbocharged engines, with either a six-speed manual or automatic. We measured 31 mpg overall in the base automatic and 30 mpg from the S with its stick shift. Handling remains very nimble and sporty but not as agile as previous generations. The ride is markedly better, though, and the cabin is quieter. Controls take some getting used to, and the backseat is still tiny. You can spend hours online configuring your ideal Mini, but options can push the price past $30,000. A hot-rod John Cooper Works bumps the power to 228 hp and gets firmer suspension. Reliability has been average.
