The tuning program is available for both the Cooper S and the Cooper D, as well as the Clubman S. Offering to increase output of the diesel-powered Mini Cooper D, which isn't yet available in the U.S., from 175hp (130kW) to 204hp (150kW), with 260lb-ft (350Nm) of torque available across the range from 1,600rpm to 5,000rpm, Hamann claims the resulting performance figures shave about a half second from the 0-100km/h (62mph) time and add 3mph (5km/h) to the top speed. The sportier Cooper S gets upgraded to 230hp (172kW) and 244lb-ft (330Nm) of torque, with a rise in top speed to 148mph (238km/h).
Both cars also get appearance tuning, with a fully functional aerodynamics kit reshaping the front, sides and rear of the car for better airflow and increased downforce. Eighteen-inch diameter, 7.5-inch wide HM EVO wheels are the standard, though customers can choose from a number of options. Hankook S1 EVO tires in 225/35Z sizing provide the grip. The chassis is lowered by 30mm, thanks to an all-new coilover suspension system. The ride height is also adjustable, allowing up to 50mm of lowering for times when clearance isn't a priority.
Inside, Hamann tweaks some of the appearance elements for a custom look, including the handbrake, pedals and a set of carbon fiber trim.
