German Porsche tuner and manufacturer founded 1939. Famous for extreme Porsche 911 modifications including the iconic Yellowbird CTR and BTR.
Ruf Automobile (often spelled RUF) is a German Porsche-focused tuner and manufacturer founded in 1939, beginning as a service garage and evolving into a tuner and ultimately a registered manufacturer. The company is unusual in that Ruf-modified Porsches can be registered as Ruf vehicles (separate from Porsche), allowing the brand to claim its own identity rather than just being a tuner.
Ruf is most famous for the Yellowbird CTR (1987-1991), a heavily modified 911 producing 469 horsepower and reaching 211 mph in tests, making it briefly the fastest production car in the world. The Yellowbird competition with the Porsche 959 and the Ferrari F40 produced legendary motoring journalism. Other Ruf classics include the BTR (Bigger Twin Turbo), the BTR2, the CTR2, and the modern CTR Anniversary models.
The current Ruf lineup includes the CTR (modern reimagining of the Yellowbird), the Rt 12 (a longer-tail variant), and the SCR (a lightweight track-focused model). Production volumes are extremely small (typically dozens of cars per year). Pricing reflects the limited production: a new Ruf CTR can exceed $1 million. The brand is widely respected within the Porsche enthusiast community for engineering ambition and historical significance.
