Ruf RK


The Ruf RK Coupe and RK Spyder are mid-engine sports cars made by Ruf Automobile in collaboration with Italian design house Studiotorino. The RK Spyder was introduced in 2005 in Turin and the RK Coupe was introduced the following year in 2006 in California.

Development and production

The RK is a result of a collaboration between German automaker Ruf and Italian coachbuilder Studiotorino, the RK Coupe and Spyder are based on the Porsche 987 Cayman and Boxster. The RK takes design clues from the Ferrari Dino 246 GT, the Porsche 550, and the Porsche 904.
Both the Coupe and Spyder feature new bodywork from Studiotorino, with some notable changes including redesigned front and rear fascias, redesigned vents in front of the rear wheels, integrated door handles with electronic door latches, forged aluminum exhaust and filler cap, custom wheels specially designed for the RK, and on the Coupe, a redesigned roofline which removes the rear quarter windows and adds a new rear hatch which replaces the sloping rear glass with a smaller upright piece and adds flying buttresses made from the existing pillars.
The RK Coupe and Spyder are both limited production models, limited by Ruf to a total of 49 Coupes and 49 Spyders. However, Studiotorino's website states that between 2005 and 2007 they only built three RK Spyders and one R Spyder, a naturally aspirated version of the RK, as well as two RK Coupes. It is unknown if any further cars were built since then.
