The German tuning team modified the car’s aerodynamics, styling, suspension, and engine.

AC Schnitzer toyed with the Mini Cooper S Cabrio’s engine which normally gives out 175 horsepower and boosted it to an exciting 208 hp. The R57 also gets a limited-slip differential putting it in the same line with the variant from John Cooper Works and the Cooper S. The car is also enhanced with a chrome tailpipe sports silencer custom made by AC Schnitzer

The R57 Cooper Cabrio gets a suspension treatment with a spring kt and a suspension set-up that is height adjustable. The suspension set up makes the mini more agile in addition to the added aluminum strut brace.

The design house also added front spoilers and installed rear skirts to improve the looks and aerodynamics of the car. Custom alloy wheel also make the Mini a flashier ride.

The interior was made sleeker with AC Schnitzer foot rest, pedals, handbrakes, and gear knobs.

The soft top Cabrio is the second generation of the model and was unveiled during the Detroit motor show last January. The soft top of this car can open in about 15 seconds even when the car is on a slow pace of 30km/hr.
