The CTR 2 Sport



astonish (a ston'ish), v.t. to strike with sudden and overpowering wonder; amaze to the utmost extent; astound.



In truth, no one word can even come close to describing the new Ruf CTR2 Sport. It is an automobile so amazing, so astonishing, that it is incomparable to any other car. Except possibly, another Ruf...





The new CTR2 Sport was introduced in June at the Virginia City Hillclimb. The accompanying images illustrate the only two Sport versions in the world. Keep in mind that the CTR2 Sport is a fully street legal car, and is not by any means a racecar. The decals on the two cars are purely for identification reasons, and were simply added on after the Canary yellow paintwork.

Last November, Ruf Automobile was proud to introduce the new CTR2 as the successor to original CTR (dubbed the Yellow Bird after it was declared the World's Fastest Production Car in high-speed shoot-outs in both America and France in the late 1980s). What was not announced was that Ruf has also developing a CTR2 Sport model, an extreme version designed for Ruf customers deprived of the unlimited speeds of the German autobahn. If a customer can not enjoy the 200 plus mph top speeds that the CTR2 offers, Alois Ruf wants to give them maximum performance in acceleration and cornering at more realistic speeds. With this goal of maximum performance, out go the air conditioning, power windows, the "tall" 215 mph+ 6 speed gearbox, etc., and on comes a lightweight wide-body to accommodate some serious rubber along with a sport suspension to match and a "short" Ruf 6 speed, geared for quick acceleration through 185 mph. The end result is the aggressive CTR2 Sport, extreme in both styling and performance.

Superior traction under acceleration, braking, and cornering were the primary design objectives, so it is no surprise that the most striking feature of the Sport is its wide-body. In fact the greatest challenge in designing the Sport was how to accommodate a wider track resulting from wider tires (11" in front and 13" rear) without destroying the sleek balance achieved with the original CTR2. Fender-flares were quickly ruled out in favor casting all new front fender molds which maintain the same lines but start 2 1/2" further out from the chassis and "shark gills" were implemented to handle the transition from where the fenders end to where the doors begin.

The CTR2 Sport retains the same 3.6 liter, air-cooled sohc, road-legal flat-6 as the standard CTR2, but to effectively put its astonishing 505 lb-ft of torque (520 PS) to the ground during "power-on ' cornering, all-wheel drive is standard on this Sport model (2wd is optional for those who want to tempt fate). Also retained is the unique carbon-carbon braking system from Carbone-Industrie with four piston calipers.
