In November 2007, Porsche announced a commemorative RS60 Spyder edition of the Boxster to celebrate Porsche's 1960 win in the 12 Hours of Sebring in Florida. Only 1,960 units were produced worldwide, with approximately 800 slated for the U.S. with each model bearing a numbered production badge on the dash. The RS60 Spyder came only in GT Silver Metallic exterior colour while the standard interior is Carrera Red leather, with dark gray leather as an option. The RS60 came standard with 19 inch Sport Design alloy wheels, Porsche's Active Suspension Management System, and a sports exhaust that increased the engine output to 223 kW (299 bhp).
