Only minor changes mark the Mini Cooper for 2004. Offered only as a 2-dr hatchback, the front-wheel-drive, 4-seat Mini is among the smallest cars sold in the U.S. The base Mini Cooper has 115 hp, the supercharged Cooper S 163, both from a 1.6-liter 4-cyl engine. Manual transmission is standard--a 5 speed for the Cooper, a 6 speed for the S. The base Cooper offers an optional continuously variable automatic transmission (CVT) with a manual mode providing six gear ratios. Antilock 4-wheel disc brakes are standard, as are front torso side airbags and front and rear head-protecting side airbags. The S gets a functional hood scoop and sport suspension with 16-inch run-flat tires vs. 15s.
