This Ruf Is Powered by a New Flat-Eight EngineRUFRuf has developed a new flat-eight engine, it at the Goodwood Festival of Speed.The B8 is a twin-turbocharged 4.8-liter eight-cylinder boxer engine producing over 1000 horsepower and 737 pound-feet of torque.The CTR3 prototype that carries the new engine will blast up the Goodwood Hillclimb with Tanner Foust behind the wheel several times over the next few days.Boxer engines are rare in the current automotive landscape. The Porsche 911, of course, still employs an array of flat-six engines, and Subaru's entire gas-powered lineup packs flat-fours, from the BRZ sports car to the three-row Ascent SUV. But now a new horizontally opposed powerplant has arrived, with German automaker Ruf today revealing a new flat-eight engine at the Goodwood Festival of Speed.The B8 engine with chief engineer Marc Brunner and founder Alois Ruf.RUFRuf is known for ultra-high-performance cars that may look like Porsches but feature unique chassis and bodywork, such as the legendary CTR Yellowbird that hit 211 mph back in 1987 in a famous Road & Track comparison test. Given Ruf's connection to Porsche, it's no surprise that the company is working on a new boxer engine, but the number of cylinders represents a significant departure from the company's storied history of flat-sixes.AdvertisementAdvertisementDesignated the B8 and internally referred to as "Erprober" or "Tester," the engine is still currently in prototype form, making its debut at Goodwood in a modified Ruf CTR3. The eight-cylinder boxer is twin-turbocharged and displaces 4.8 liters, with Ruf claiming that it produces over 1000 horsepower and 737 pound-feet of torque. No other specific details about the engine were provided.RUFThe engine was designed and developed entirely in-house, Ruf says, and it's housed inside a lengthened CTR3, Ruf's mid-engined sports car that looks like a stretched Porsche Cayman on steroids. The CTR3 prototype's body is 3.9 inches longer to accommodate the engine, and the B8 is hooked up to a six-speed manual transmission. The test car's special livery is inspired by the Blossom Yellow hue that gave the 1987 CTR its Yellowbird nickname, and it includes graphics that symbolize the eight-cylinder setup.Ruf says the B8 is not yet ready for production, but "serves as a dedicated testbed for technologies that will shape a future RUF model." We imagine it won't be terribly long before this engine appears in a production-spec Ruf.The B8-equipped CTR3 test mule will run up the Goodwood Hillclimb twice a day from Friday, July 10, to Sunday, July 12, during the "Supercar Run," and will be piloted by rally, stunt, and drift driver Tanner Foust. If you aren't lucky enough to attend this year's Festival of Speed in person, you can tune into the event's YouTube livestream for a chance to hear this unique engine roar for the first time.➡️ Skip the lot.
