The Cooper S Roadster is the mid-level version of MINI’s most sporting convertible model. Thanks to a turbocharger, the Cooper S Roadster provides a healthy boost in power compared to the base model while maintaining a focus on nimble handling dynamics and a unique look that blends traditional, quirky MINI styling cues with a newfound athleticism.
The two-seat Cooper S Roadster is heavily based on the Cooper S Coupe, which in turn borrows handling-enhancing components such as rigid, reinforced rocker sills from the four-seat Cooper S Convertible. This convoluted lineage essentially means that the Cooper S Roadster and Cooper S Convertible models share most of their major mechanical bits, yet MINI says the Cooper S Roadster is different thanks to an emphasis on performance and style over practicality.
Like all Roadsters, the Cooper S Roadster is distinguished from its drop-top kin by a more steeply raked windshield, a 0.9-inch lower roof and structural bracing (and storage space for the convertible top) where the rear seats would be in the normal Convertible. The top is a lightweight unit that can be raised or lowered manually, a task made easier by button-activated pneumatic springs that release the top from its stowage well and bring it into a more easily reachable position.
Unlike the multiple contrasting-color roof options for its Coupe sibling, the Cooper S Roadster’s top comes only in black. From the waist down, the car looks like a normal Cooper S Coupe model, but the steeply sloping convertible top and stubby trunk set it apart.
Truncated though it may be, the trunk is capable of holding a useful 8.5 cubic feet of cargo whether the top is up or down, and its usefulness is extended by a pass-through feature that allows the storage of long items such as skies. The passenger compartment utilizes the traditionally quirky Mini control and instrumentation layout, with an enormous speedometer in the center of the dash and a steering-column mounted tachometer. In keeping with the nature of the car, sport seats are fitted as standard.
Providing power in the Cooper S Roadster is a direct-fuel injected 1.6-liter inline-four cylinder. The little engine sports parent company BMW’s flexible VALVETRONIC variable valve timing technology and produces 181 horsepower and 177 lb-ft of torque at 1,600-5,000 revs (192 lb-ft in overboost mode).
While many sporty cars can only claim to have go-kart-like handling, the Cooper S Roadster delivers on the promise: the short wheelbase ensures extremely quick direction changes, the steering is quick and communicative and the chassis provides a good ride and handling compromise. Helping the car’s moves is a spoiler built into the tailgate that automatically raises above 50 mph to provide up to 88 pounds of extra downforce.
Standard and Optional Features
Befitting the brand’s quasi-premium intentions, the Cooper S Roadster features a healthy list of standard equipment including speed-sensitive power steering, electrically adjustable exterior mirrors, height-adjustable seats, air conditioning and an audio system with MP3-compatible CD player and AUX IN connection.
Options include park distance control, adaptive headlights, comfort access, automatic climate control, automatically dimming rear-view mirror and exterior mirrors, Harman Kardon hi-fi loudspeaker system, a navigation system, and MINI Connected, which has features like web radio, Google services, RSS news feeds, Mission Control, and in-car use of Facebook and Twitter.
Additionally, a wide variety of racing stripes, graphics and unique upholstery options are available for customers desirous of additional personalization.
Safety
In the event of a collision, the Cooper S Roadster comes equipped with dual front and head-thorax airbags, which are integrated into the sides of the seat backrests and protect the head, upper body and hip area from injury in the event of a side impact. In the event of a rollover, the car comes prepared with an extremely rigid windscreen frame and polished stainless steel roll-over bars that protect occupants’ heads.
Helping to prevent a crash in the first place are traction and stability control systems as well as ABS and a tire-pressure monitoring system.
Key Competitors
Drop top rivals close to the Cooper S Roadster in price include the similarly sized Mazda MX-5 Miata in addition to more powerful but much larger rides like the Ford Mustang Convertible and the Chevrolet Camaro Convertible.
