All-Season Traction Control arrives standard on Cooper S convertibles, but is not available on base models. The system limits front wheelspin, which is particularly helpful given the higher power flowing through S models. However, all MINIs are available with Dynamic Stability Control, which uses sensors to modulate braking and throttle engagement, and help keep you on track. Handling is also aided by Sport Suspension - standard on Cooper S and optional on Cooper models - a package that includes larger front and rear anti-sway bars.

In addition to the hood scoop and center mounted exhaust, Cooper S convertibles gain sport styled bumpers, revised door sills, and a body-colored grille (base Coopers get a chrome grille). Larger 16-in. alloy wheels are stock on S models and can grow to 17 in. Base Coopers start at 15 in. and expand to 16. Standard features on both include a Flat Tire Monitor, heated rear window glass, an engine immobilizer, and speed-sensitive windshield wipers. Options include heated outside mirrors, heated windshield washer nozzles, auto leveling xenon headlamps, rain-sensing wipers, front fog lights, and racing stripes on S models.

Inside, dual-stage front airbags vary the level of deployment according the status of the front passengers. Side impact airbags mounted in the seats protect lateral integrity. Unlike coupes, however, convertibles do not include any type of curtain airbag.

Other interior features include power front windows, 6-way manual adjustable seats, a three-spoke leather steering wheel with tilt, an air-conditioned glove box, a 50/50 split rear seat, and a stereo volume control that responds to vehicle speed. Options include leather upholstery, heated front seats, Sport seats (standard on Cooper S), cruise control with steering wheel controls, an onboard computer, navigation, automatic air conditioning, an integrated garage door opener, Sirius satellite radio, and an upgraded Harmon Kardon stereo system.
