Ruf Debuts New Flat-Eight Engine at Goodwood
The boxer-eight makes 1,000 horsepower and 738 pound-feet of torque, and Ruf pairs it with a six-speed manual transmission.
- At the Goodwood Festival of Speed, German automaker Ruf unveiled a new twin-turbocharged 4.8-liter flat-eight engine producing over 1,000 horsepower and 737 pound-feet of torque, paired with a six-speed manual transmission.
- Internally referred to as 'Erprober,' or 'Tester,' the prototype engine serves as a dedicated testbed for technologies that will shape a future RUF model within a modified Ruf CTR3 chassis.
- Rally and drift driver Tanner Foust will pilot the B8-equipped CTR3 test mule up the Goodwood Hillclimb twice daily from Friday, July 10, to Sunday, July 12, during the 'Supercar Run.'
- Designed entirely in-house, the engine marks a departure from Ruf's historical reliance on Porsche components, with the company noting that no other manufacturer has deployed such an engine 'in this form.'
- Work on a production-ready vehicle is well advanced, with Ruf noting all its cars begin life 'long before the world sees them,' with future models potentially carrying the CTR4 nameplate.
