Most folks know [the brand]() for its Yellowbird: [a Porsche 911-based, twin-turbo sliding machine]() that hit 211 miles per hour in 1987. It certainly didn't stop there, though, as Ruf is still building wickedly powerful machines with P-Car influence. Its latest is actually an engine—a boosted, 4.8-liter flat-eight making more than 1,000 horsepower and 737 lb-feet of torque–and it's debuting at the Goodwood Festival of Speed. The horizontally opposed power plant finds its home for now in a CTR3 prototype body that's been stretched 3.9 inches. Ruf plans to stuff it in a production car later on, though it's unclear what shape said car will take. All I know is that this test mule looks sick, especially in that black-and-yellow livery. And it has a six-speed manual! ![Ruf 8 Zylinder prototype]() ![Ruf 8 Zylinder prototype]() ![Ruf 8 Zylinder prototype]() ![Ruf 8 Zylinder prototype]() ![Ruf 8 Zylinder prototype]() Ruf has yet to reveal many details about the B8 engine, as it's called, only divulging that it was designed and developed in-house. As far as I can tell, there's never been a production car with a flat-eight; only Porsche motorsport specials in the 1960s. That would make it pretty tough to copy anyone else's homework, I assume. There's a special event at the Goodwood Festival of Speed this week where bystanders can hear the engine fire for the first time. (We even got a save-the-date invite.) The B8 Prototype will run up the famed Goodwood hillclimb twice a day from Friday, July 10, through Sunday, July 12. And who better to drive it than beloved race pilot and *Top Gear* alum, Tanner Foust? ![Ruf 8 Zylinder prototype]() **Ruf** I'll be on the lookout for more deets, and you can bet I'll update this blog with the flat-eight's exhaust note when it gets posted online. ***(Update: It's here! Fast forward to 4:09 if it doesn't start there automatically.)*** https://youtu.be/oPBwGlWjVS0?t=249 *Got a tip or question for the author?
