The MINI Cooper has already earned a reputation for being fun to drive and remarkably spacious considering its pint-sized interior. A new version introduced in 2007 features a new 1.6 liter engine derived by BMW, MINI's parent company. Thanks to the new engine, the base-model MINI Cooper is more powerful, more fuel efficient, and produces cleaner tailpipe emissions.
