Mini Cooper models feature twin-power turbo engines that deliver high torque at engine speeds as low as 1,250 revolutions per minute. A flat panel under the engine works to minimize resistance and reduce overall fuel consumption, while the electric-powered assisted steering system only activates when needed to modulate fuel consumption and operating efficiency. Minis also feature high-strength steel front and side panels, reducing body torque, vibrations and cabin noise, anti-lock brakes and a crash sensor system.
Comparing the two-door Cooper hardtop, the Cooper S two-door hardtop and the Cooper Roadster, these twin turbo engines are three-cylinder, four-cylinder and 16-valve, four-cylinder, respectively. The Cooper and Cooper S seat four adults and the Roadster, two, all with front and side airbags. All also come with performance suspension, dynamic stability and traction control, as well as hill assist. Wheel options for these models vary, ranging from 15 inches to 18 inches. All Mini Cooper models come with a four-year, 50,000 miles warranty and three years or 36,000 miles of no cost maintenance.
John Cooper Works models are built for high performance with 208-horsepower turbocharged engines. The John Cooper Countryman All4, an all-wheel drive model, seats five and its engine generates 292 foot-pounds of torque with an over-boost function that delivers 297 foot-pounds. It also features a reinforced clutch and six-speed manual gearbox.
Several Mini models feature a green mode that regulates fuel consumption, guides acceleration and provides cost-saving information to the driver via the car's connected screen. It is also possible to engage a coasting feature when in green mode, which disengages the automatic transmission to control deceleration.
