RUF presents 2017 CTR during Geneva Motor Show

Article by Christian A., on March 7, 2017

RUF Automobile GmbH officially unveiled during the 2017 Geneva Motor Show its latest CTR halo model. This model is distinct for two reasons. First is that it comes in a body that honors the 1987 CTR “Yellow Bird.” The second reason is that it utilizes a chassis based on the company’s very own design.

Already in the fourth generation, the 2017 RUF CTR is indeed similar to the model that it pays tribute to not only in form but even in function. Making it a true masterpiece is the new engine with a weight-to-power ratio of 3.5 pounds for every horsepower. Further, it is the first rear-wheel drive with a customized carbon fiber monocoque chassis.

Indeed, the main defining characteristic of the 2017 CTR is the chassis though one can argue that the technological superiority of this model begins at the skin, which is made up completely of carbon fiber. This is the same material the chassis is composed of and comes in the patented RUF design. In addition, both crash structures in the front and the rear are composed of lightweight steel much like the roll cage that was integrated to it.

This is important given that these two were made with the goal of maximizing occupant safety. It is this use of more modern materials that resulted in the 2017 CTR having dry weight measured at 2,640 lbs. (1,200 kg.).

According to Estonia Ruf, the development of this new model started five years ago with the aim of releasing a model that would offer an exciting analog driving experience but have manual transmission, the latest in racing technology, an excellent power-to-to-weight ratio.

Company owner and President Alois Ruf meanwhile said that he has long had a vision for the concept for this model. The company has been waiting for the right time to create its own car and what better way to do it than during the Yellow Bird’s 30th anniversary, he added.

In terms of the interior, RUF revealed that a minimalist principle was followed but the use of lightweight materials was ensured as a tribute to the analog philosophy.

The 2017 CTR will be manufactured at the company’s facility located in Pfaffenhausen, Germany, with actual series production slated to start by 2018. A total of 30 units will be made for the limited run. RUF though has yet to announce how much this model is priced.

Powertrain

Similar to many other models that the company has released, the 2017 CTR also makes use of the rear-engine powertrain configuration. The engine that powers this model, inspired by that the Yellow Bird, is the flat-six twin-turbo 3.6-liter engine.

It is capable of delivering 710 PS (522 kW) which is available at 6,750 rpm with peak torque of 649 lb.-ft. (880 Nm).

This allows for a maximum speed of 225 mph (360 km/h) with acceleration from 0 to 62 mph (0 to 100 km/h) in shorter than 3.5 seconds. From standstill to 200 km/h meanwhile, the 2017 CTR only needs less than 9 seconds.

2017 RUF CTR Unveiled in Geneva

Revered sports car manufacturer RUF Automobile GmbH unveiled the latest generation of its famed CTR halo car today during the 87th Geneva Motor Show. This is the first RUF sports car to be based on a chassis completely of the firm’s own design with a body that pays tribute to the 1987 CTR “Yellow Bird.” “The concept for the 2017 CTR is one that I have had in my head for a very long time,” said Alois Ruf, President and owner of RUF Automobile GmbH.

“We have been waiting for the right point in our history to build our own car and the 30th anniversary of the CTR ‘Yellow Bird’ is that moment.”

New Chapter in a David and Goliath Story Entering its fourth generation, the latest high-performance RUF supercar pays homage to the 1987 CTR Yellow Bird in both form and function. A weight-to-power ratio of only 3.5 lbs per horsepower, a first-ever rear-wheel drive bespoke carbon fiber monocoque chassis and an incredibly powerful engine are only some of the ingredients that make the latest CTR such a compelling work of automotive art.

Design inspiration comes directly from the 1987 Yellow Bird’s focus on aerodynamic efficiency. The silhouette, narrow body, rear air inlets and fascias are all direct nods to the company heritage. The body, now formed in carbon, calls back to the original car’s flushed look. Center-locking 19-inch forged alloy wheels complete the design wrapped in tires measuring 245/35ZR19 in the front and 305/30ZR19 in the rear.

Powerful, Traditional and Thoroughly Modern Technological sophistication starts with the skin, which is made completely of carbon fiber. For the first time, the chassis beneath that surface – also made of carbon fiber - is a bespoke monocoque, a proprietary RUF design. The front and rear crash structures are built with lightweight, steel as is the integrated roll cage that are both designed to maximize occupant safety. In total, the extensive use of modern materials allows for an extremely light dry weight of 1,200 kg (2,640 lbs).

Like most RUF works, the 2017 CTR uses a rear-engine powertrain layout. The 3.6-liter twin-turbo flat-six is built by RUF and inspired by the design of the engine in the original Yellow Bird. To that end, it uses a dry-sump lubrication system to provide constant oil supply and pressure during extreme cornering. Total output is 522 kw (710 PS) at 6,750 RPM and 880 Nm (649 lb-ft) at 2,750 RPM, allowing acceleration from 0-100 km/h (62 mph) under 3.5 seconds and 0-200 km/h (125 mph) under nine seconds.

Top speed is 360 km/h (225 mph). In order to truly pay tribute to the Yellow Bird, the latest CTR will be available exclusively with a newly-developed six-speed manual transmission that sends power to the rear wheels through a limited-slip differential.

“We began development on the new CTR five years ago with the goal of creating a thrilling, analog driving experience that combines an amazing power-to-weight ratio, manual transmission and modern racing technology,” said Estonia Ruf. Ensuring excellent handling characteristics, the 2017 CTR uses double-wishbone suspension arms in a pushrod configuration for both the front and rear axles.

Internally vented and perforated carbon ceramic brake discs (380 mm front, 250 mm rear) clamped by six-piston fixed calipers (front) and four-piston calipers (rear) offer maximum stopping power and enduring fade resistance. Minimalist Interior as a Mark of Analog Design A minimalist two-seat interior designed with lightweight materials is a further acknowledgement of the 2017 CTR’s analog philosophy.

Alcantara is the upholstery of choice both for its aesthetics and weight saving properties that, in combination with leather and carbon fiber, give the cockpit a balance between modern and retro design. The seats are made of carbon fiber, and the pedals from aluminum. A three-spoke steering wheel is a further nod to the car’s racing pedigree, as are the analog dial-type gauges in a green typeface.

Series production is scheduled to begin by 2018 at RUF’s Pfaffenhausen, Germany, facility. The limited run will include 30 units not including the prototype unveiled during the 2017 Geneva Motor Show. Pricing to be announced. A Nickname Turned Legend The RUF CTR debuted in 1987. Capable of incredible speed, the 469-bhp twin-turbo CTR reached 342 km/h (213 mph) during testing on the Nardo Ring, a shocking speed for its time that is still impressive to this day.

It was in the same year that RUF gained approval from the U.S. National Highway Transportation Safety Administration and Environmental Protection Agency to sell its cars in America. Shortly thereafter, Alois Ruf brought the car to Road & Track’s “World’s Fastest Car” competition at Volkswagen’s Ehra-Lessien test track in Germany. The CTR was one of nine cars in attendance including a Ferrari Testarossa, a Lamborghini Countach 5000S and a Porsche 959.

The photographers from Road & Track noticed how the CTR’s bright paintwork stood out against the coincidentally dull weather and gave it the nickname “Yellow Bird.” What happened next would contribute to making that name stick forever. About RUF Automobile Gmbh: In 1939, Alois Ruf Sr. first formed his company, AUTO RUF, as a general service garage.

Despite a challenging economy, the company grew and in 1949 he added a gas station to the company complex. By 1955, Ruf Sr. recognized a need in Germany for a full-size tourist bus and challenged himself to build his own tour bus to run this as a separate business. In 1963, the company began specializing in Porsche vehicles, a direction that Alois Ruf Jr. vowed to continue when he assumed directorship of the company in 1974. In the following year, the first RUF-enhanced Porsche model made its debut. Now it is still family run by Alois and Estonia Ruf.
