Ruf reengineers Yellowbird for 2017 with all-new fourth-gen Ruf CTR

Renowned Porsche tuner and bespoke car manufacturer Ruf Automobile has resurrected its fabled CTR nameplate for 2017 by coming up with a car of its own design and engineered by it that pays tribute to the supercar that put the Ruf brand on the automotive map:  the 1987 CTR “Yellowbird.”

“The concept for the 2017 CTR is one that I have had in my head for a very long time,” said Alois Ruf Jr., 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.”

Although the 2017 Ruf CTR looks like a faithful rendition of the Yellowbird, it's actually a different beast altogether since it has a carbon-fiber monocoque chassis, with the 3.6-liter twin-turbo flat-six engine putting out 700 hp and 880 Nm of torque through the rear wheels via a limited-slip differential and a newly-developed six-speed manual transmission. This gives the fourth-generation CTR a power-to-weight ratio of 1.57 kg per horsepower and makes it the first-ever supercar with a rear-engine, rear-wheel drive, carbon fiber monocoque chassis. Performance figures are 3.5 seconds for a zero to 100 kph sprint while zero to 200 kph is dispatched in less than nine seconds, with top speed attained at 360 kph.

To ensure that the 2017 CTR can take on corners, Ruf fitted it with a pushrod-configuration double wishbone suspension for both front and rear wheels. Keeping the car's power in check are internally vented and perforated carbon ceramic brake discs at 380 mm up front and 250 mm at the back clamped by six-piston fixed calipers (front) and four-piston calipers (rear).

Outside, the 2017 CTR looks every inch like the classic 1987 CTR, from the silhouette to the narrow body and the rear air inlets, except the entire body is now rendered in carbon fiber. 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.

A first for Ruf is the carbon fiber chassis which is a proprietary design while the front crash structure is built with lightweight steel, as is the integrated roll cage, "that are both designed to maximize occupant safety." With the extensive use of strong yet lightweight materials, the 2017 CTR has a dry weight of only 1,200 kg.

A very limited production run of the 2017 Ruf CTR will begin in 2018 at the company's Pfaffenhausen facility in Germany with only 30 units to be produced, excluding the prototype that was unveiled at the 2017 Geneva Motor Show.
