Introduced in 2015, the five-door variant of the fun and fashionable MINI Cooper comes standard with a turbocharged 1.5-litre triple-cylinder engine that produces 134 horsepower. Meanwhile, the Cooper S features a turbocharged 2.0-litre four-cylinder delivering 189 horsepower. There is no John Cooper Works model, here. The company made a few changes last year including some styling revisions, a new adaptive suspension and an updated interior.
