 It was introduced in 1998 after the discontinuation of the CTR2 (another 993 generation based car), however Ruf still wanted a supercar offering to be available and so the Turbo R became the supercar offering from Ruf for the 1998 model year and endured a very short production run of only one year.The Turbo R is powered by the twin-turbocharged 3.6L (3600 cc) flat-six engine from the Porsche 993 Turbo reworked by Ruf to produce at 5500 rpm and of torque at 4500 rpm.Computer-controlled all-wheel drive is standard and power is sent to the wheels through a 6-speed manual transmission.
