Most companies would be content with a resume that includes the Yellowbird. RUF, the Pfaffenhausen outfit that sent a twin-turbo 911-shaped missile past 211 mph in 1987, has never been most companies.
And while the rest of the performance world busies itself with battery packs and electric torque fill, RUF just rolled into the Goodwood Festival of Speed with something nobody had on their bingo card. A brand-new engine, built from scratch.
Eight Cylinders, Zero Batteries
Now, let’s talk about what we came here for. The B8 is a 4.8-liter twin-turbocharged flat-eight producing over 1,000 horsepower and 737 lb-ft (1,000 Nm) of torque, which is an insane output for an engine with no hybrid system whatsoever. Just displacement, boost, and eight horizontally opposed pistons.
Better still, the whole thing was designed and developed in-house. And that includes the six-speed manual transmission bolted behind it, because apparently RUF didn’t get the memo that four-digit horsepower and three pedals aren’t supposed to mix anymore.
The Layout Racing Never Shared
Here’s the thing about flat-eights. They have real history, but virtually all of it lives on the track, where Porsche campaigned the layout in Formula 1 and sports prototypes throughout the 1960s. A production road car has never carried one.
That’s the gap RUF is aiming at. In the brand’s own words, this is “a new chapter in automotive history.”
A Test Mule in Yellowbird Clothing
For now, the B8 lives inside a CTR3 prototype that’s been stretched 3.9 inches to handle the wider engine. RUF has nicknamed it the Erprober, German for “tester.”
The matte black bodywork wears a Blossom Yellow livery that nods straight back to the Yellowbird, with flowing figure-eight graphics telling you exactly what’s out back. The engine itself is destined for a future production RUF, though the brand is keeping quiet on what that car will be.
