RUF CTR Anniversary
At the 87th Geneva Motor Show, we presented the first member of a completely redesigned high-tech generation: the RUF CTR Anniversary. For the first time, the superior two-seater is based on a carbon fiber monocoque completely developed by RUF; its type abbreviation CTR is reminiscent of the legendary “Yellowbird”, the first RUF biturbo coupé, which thirty years ago astonished the world of super sports cars.
“The first automobile that was completely conceived and manufactured by us marks a very special chapter in our company's history. His 30th birthday presentation of the celebrated Yellowbird is exactly the right moment. " Alois Ruf
“I really thought about the concept for the CTR Anniversary for a long, long time,” recalls Alois Ruf.

The design of the CTR Anniversary follows the guidelines that the first Yellowbird once set:
Uncompromising aerodynamic efficiency thanks to the development of the shape in the wind tunnel. The aerodynamic silhouette, the narrow body, as if crouched under the wind, the rear air intakes and even the instrumentation are a grandiose reflection of the first draft. With one difference: the streamlined body of the CTR Anniversary is made of neither sheet steel nor aluminum, but the Formula 1 material carbon fiber. The footprint of the CTR Anniversary corresponds to the high-performance concept: Forged aluminum rims in 19-inch format have 245/35 ZR 19 tires on the front wheels and 305/30 ZR 19 tires on the drive axle.
Powerful, tried and tested, but completely up to date
The technical perfection of the CTR Anniversary can already be seen in the carbon fiber body. For the first time, the load-bearing chassis element underneath is a carbon fiber monocoque completely developed and manufactured by RUF. The axle carrier and crash structure of the front end are made of high-strength steel tubes, which, like the integrated safety cage of the CTR Anniversary, optimally protect the occupants thanks to their extremely stable structure.
A similar construction made of steel tubes and light metal beams milled from solid material accommodates the drive train in the rear. The high safety reserves of the super sports car do not go hand in hand with additional weight thanks to the know-how that has grown at RUF over decades: The CTR Anniversary weighs only 1250 kilograms dry.

New chapter in our story of David and Goliath
As with most of the noble RUF Coupés, the rear-engine concept is also used in the CTR Anniversary. The flat six-cylinder boxer engine with its 3.6 liter displacement corresponds to a direct further development of the power package in the rear of the Yellowbird. In the new CTR, RUF also uses a dry sump lubrication system from racing, which, thanks to its high throughput, optimally supplies all moving parts in the engine even under the brutal centrifugal forces in very fast, long bends. The rated output of this powerhouse is 6750 rpm at 522 kW (710 hp); the maximum torque already occurs at 2750 rpm and is no less than 880 Nm (649 lb-ft).
The range between peak torque and maximum output, which is exemplary for a sports engine, promises a new quality of drivability for this super engine, especially in normal road use. From a standstill, it takes less than 3.5 seconds to reach 100 km / h; the 200 km / h margin is reached in less than 9 seconds. The maximum speed is more than 360 km / h.
The role model function of the Yellowbird is also carried over to the transmission: It was completely redeveloped by RUF and has seven gears that are shifted by hand. For us at RUF, this results in the most harmonious way to enjoy the new CTR behind the wheel. The axle drive takes place via a locking differential.
"We started designing the breathtaking variant of a super sports car that could drive analogously five years ago," explains Estonia Ruf. “We reduced all otherwise digitally controlled functions and combined the fascinatingly original, unadulterated way of driving with an astonishingly low power-to-weight ratio, a manual gearbox and modern racing technology.”
In addition, the new CTR Anniversary has excellent handling. The basic layout of the chassis consists of independent wheel suspensions on double wishbones, combined with spring-damper units mounted lengthways on the chassis, which, as in Formula 1, are actuated by push rods. The dimensions of the internally ventilated, perforated ceramic brake discs correspond to the enormous forces that they have to tame: Six-piston brake calipers and discs with a diameter of 380 millimeters are used at the front, four-piston calipers and 350 mm discs at the rear. This braking system stands for maximum, low-fading deceleration forces.
Minimalism in the interior as an emblem of analog design
A pared-down interior in the new CTR Anniversary forms the opposite pole to the often cluttered instrument panels in the digital age. Two seats and selected high-quality, but super-light materials form the core of this almost unbelievable statement on analogue driving pleasure. The Alcantara covers promise not only aesthetic enjoyment, but also low weight. In combination with the cockpit materials leather and carbon fiber, they create a wonderful balance between contemporary technology and an emotional retro perspective. The seats are also made of a carbon fiber composite, the perforated pedals are made of light metal. The three-spoke steering wheel is another element that connects the new CTR with racing history, as are the analog dials of the instruments with their green shimmering numbers.
Series production of the new CTR will start in 2018 at RUF in Pfaffenhausen. A limited edition of 50 copies is planned, which does not include the prototype shown here in Geneva for the first time.
A nickname becomes legend
The first RUF CTR made its debut in 1987. Built for an unrivaled top speed, the 469 PS Coupé reached 339.8 km / h when measured on the record track at Ehra Lessien. This event was organized by the American car magazine Road & Track. The second fastest vehicle was the newly introduced Porsche 959 with a top speed of 317 km / h. In the light haze of the north German lowlands, the yellow of the RUF CTR shone unmistakably and the editors of Road & Track gave the narrow coupé the nickname “Yellowbird”. What happened after that stamped the name RUF as an unforgettable record in the history of sports cars. In the year of the record, RUF received U.S. approval from the U.S. National Highway Transportation Safety Administration and the Environmental Protection Agency to sell and register their own cars there.
