The Ruf RK Coupe and RK Spyder are mid-engine sports cars made by Ruf Automobile in collaboration with Italian design house Studiotorino.

[2] The RK is a result of a collaboration between German automaker Ruf and Italian carozzeria Studiotorino,[3] the RK Coupe and Spyder are based on the Porsche 987 Cayman and Boxster.

Both the Coupe and Spyder feature revised bodywork by Studiotorino, including redesigned front and rear fascias, redesigned vents afront the rear wheels, integrated door handles with electronic door latches, forged aluminum exhaust and filler cap, custom wheels.

[5][1] Power comes from a 3.8 litre flat-6 engine from the Porsche 997 911 which has been supercharged in both models (the RK stands for Ruf Kompressor), with the RK Spyder rated at 313 kW (420 hp) and 450 N⋅m (332 lbf⋅ft) of torque and the RK Coupe rated at 324 kW (434 hp) at 7,000 rpm and 470 N⋅m (347 lb⋅ft) of torque at 5,500 rpm.

Ruf also produced a naturally aspirated version of the RK Spyder, called the R Spyder, whose engine is rated at 350 hp (261 kW) at 6,600 rpm and 400 N⋅m (295 lb⋅ft) of torque at 4,600 rpm, propelling the car from 0-100 km/h (62 mph) in 4.7 seconds and on to a top speed of 280 km/h (174 mph).
