Hoo boy, RUF has built a 1,000bhp+ boxer engine with *eight* cylinders

Welcome to the ‘Boxer-Eight’: 4.8-litres of twin-turbo fury

Published: 09 Jul 2026

RUF Automobile has built an engine with eight cylinders and many horsepowers. It is called the ‘Boxer-Eight’ – or B8 for short – and it has been slotted into a modified RUF prototype ahead of a demonstration run at the Goodwood Festival of Speed.

Fitting, because this B8 churns out more than 1,000bhp and 738lb ft of torque and- oh, what’s that, the whole ‘boxer-eight’ thing? Yes, RUF has built an engine with eight horizontally-opposed cylinders. A flat-eight. Flat-eights aren’t usually bolted into road cars (except for Gary Oldman’s new favourite company, Runge, of course).

No, they’re normally associated with racing machinery, and of course it was Porsche who pioneered the flat-eight for Formula One and sportscar prototypes decades ago. “A boxer-eight has never been part of our story,” said boss Alois Ruf, “or anyone else’s in this form, so we decided to write a new chapter in automotive history.”

That new chapter is internally known as the ‘Erpober’ – ‘Tester’ – comprised of 4.8-litres and two turbochargers, slotted into a modified RUF CTR3 to showcase the fact it’s being designed for future road use.

Said CTR3 has been stretched by 100mm so that it can absorb those eight flat cylinders, and also features a six-speed manual gearbox. “The decision to use the CTR3 supercar was strategic,” said RUF, “allowing [us] to test the limits of the new engine’s performance while remaining under the radar.”

Not so much under it any more, not least with that new livery that depicts eight furious cylinders working furiously. "When designing the B8 livery, I wanted the graphics to tell the story of the car before anyone even heard the engine,” said Mr Ruf. “Every line represents movement, and the flowing form of the number eight became a natural symbol, not only for the new boxer-eight cylinder, but for the endless pursuit of improvement and refinement that has always been part of our family's philosophy.

“Combined with the unmistakable Blossom Yellow of the CTR Yellowbird, the design honours our heritage while looking confidently toward the future.”

We do not know when this future will materialise, but we do know Tanner Foust – may have heard of him – will be driving the prototype B8 at Goodwood throughout the weekend.
