What is Ruf?

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.

Frequently asked questions

What is the Ruf Yellowbird?
The Ruf Yellowbird CTR (1987-1991) is the company most famous product. Heavily modified 911 (specifically the 930 Turbo chassis), 469 horsepower, 211 mph top speed verified at the Volkswagen test track. Briefly held the production car top speed record. Around 29 Yellowbirds were built; clean examples now sell for $4-8 million at auction.
Is Ruf actually a manufacturer?
Yes. Ruf is registered as a manufacturer (not just a tuner) with German authorities. Ruf-modified Porsches can be VIN-stamped as Ruf vehicles (separate VIN from the original Porsche). This unusual status is shared with Alpina and a handful of other tuner houses; most tuners do not have manufacturer status.
How much does a new Ruf cost?
Current Ruf models (CTR, Rt 12, SCR) start at around $750,000 and can exceed $1.5 million depending on customization. Production is extremely limited (typically dozens of cars per year). The pricing reflects the small production volumes and bespoke nature; comparable performance from a Porsche GT3 RS costs significantly less but lacks the brand uniqueness.
Are Ruf cars purely Porsche-based?
Yes, primarily. Modern Ruf models start with Porsche 911 chassis and powertrain, then heavily modify. Some early Ruf vehicles started with chassis-only and used non-Porsche engines, but the company core identity has been Porsche-based for decades. Recent Ruf cars including the CTR have used carbon fiber chassis with Porsche-derived powertrains.
What was so special about the Yellowbird?
The Yellowbird showcased what was possible with extensive 911 modification: the 930 Turbo chassis pushed to 469 horsepower with sophisticated engine work, twin turbochargers, and exhaustive engineering refinement. The 211 mph top speed, achieved at a time when most production cars were limited to 155-180 mph, was extraordinary. The car beat the 959 and was the production car top speed champion briefly.
