Ruf CTR [SEP] manufacturer
Ruf CTR
The Ruf CTR (Group C, Turbo Ruf) also known as the CTR Yellowbird or simply Yellowbird, was a limited-production, high performance sports car manufactured by German automobile manufacturer Ruf Automobile.
Introduced for the 1987 model year and based on the Porsche 911, the CTR featured an enlarged and highly tuned version of Porsche's 3.2 litre flat-six cylinder engine, lightened body panels, an integrated roll cage (adding chassis stiffness in addition to occupant safety), upgraded suspension and braking systems,
and serial numbers, and are recognized as production models, rather than modified Porsches. Ruf is historically known for its record breaking 211 mph CTR, and is the largest, most renowned company to make Porsche performance enhancements. Though primarily a manufacturer, Ruf has also made a name for itself operating as a car tuner, a specialist in customer-requested Porsche-to-Ruf conversions (e.g. Turbo R conversions), and a restorer of classic Porsche and Ruf models. Ruf carries out service and crash repair, as
