Ruf’s New Flat-Eight Engine Is Completely Insane, and That’s Exactly the Point
Ruf just dropped one of the most bonkers engine reveals in recent memory at the Goodwood Festival of Speed, and it’s not what anyone expected. The German tuning house—famous for building absurd Porsche-based hypercars—has engineered an entirely new twin-turbocharged 4.8-liter flat-eight boxer engine that produces over 1000 horsepower and 737 pound-feet of torque. This isn’t some rebadged motor or a frankenstein mashup. It’s a completely in-house design, and it’s sitting in a modified CTR3 that’s about to assault the Goodwood Hillclimb.
Let that sink in for a second. A flat-eight. In 2024, when the automotive industry is obsessed with turbocharging four-cylinders and stuffing V6s into crossovers, one of the world’s most uncompromising performance shops decided to hand-build a horizontally opposed eight-cylinder engine from scratch. That’s the kind of move that makes you question a company’s sanity in the best possible way.
Why a Flat-Eight Matters (Even If It Seems Insane)
Boxer engines are dying. Horizontally opposed powerplants have been steadily phased out of production vehicles for decades. The Porsche 911 still carries flat-sixes, and Subaru’s BRZ and Ascent rock flat-fours, but that’s basically it. Most automakers abandoned the configuration because it’s expensive to manufacture, demands a longer chassis, and doesn’t fit easily into crossovers—which is where the money is.
Ruf doesn’t care about money in the way normal companies do. The company has built its entire reputation on building cars that are unapologetically difficult to justify on a spreadsheet. This is the same outfit that created the legendary CTR Yellowbird, which hit 211 mph back in 1987 in a famous Road & Track comparison test—a record that stood for years and established Ruf as the unhinged performance house that wasn’t afraid to chase outright speed when nobody else would.
So the flat-eight makes sense through a Ruf lens. It’s not the sensible choice. It’s the obsessive choice. It’s what happens when you have access to Porsche tooling, a crew of engineers who live to complicate things, and zero pressure to appeal to normal human beings.
The CTR3 Gets the Full Treatment
The test car is a modified Ruf CTR3—the company’s mid-engine sports car that looks like someone gave a Porsche Cayman an extra shot of espresso and hit it with a steel mallet. To make room for the flat-eight, Ruf stretched the CTR3 by 3.9 inches, and the whole thing is wrapped in special livery inspired by the famous Blossom Yellow of the original Yellowbird. There’s even graphic work on the bodywork that symbolizes the eight-cylinder layout because subtlety is apparently not in Ruf’s vocabulary.
The B8 engine—internally called “Erprober,” or “Tester”—is currently mated to a six-speed manual transmission. Yes, you read that right. A thousand-horsepower flat-eight with a stick shift. This isn’t a prototype with an automatic gearbox waiting for production refinement; this is Ruf saying, “We’re going full analog with this thing.” That decision alone tells you everything you need to know about the company’s priorities.
Rally and drift driver Tanner Foust will be piloting the CTR3 up the Goodwood Hillclimb twice daily from July 10-12 during the Supercar Run. If you can’t make it in person, Goodwood’s YouTube livestream will cover the action, so you’ll actually get to hear this engine scream in anger for the first time.
This Isn’t Production—Yet
Ruf is being careful with language here. The company explicitly states that the B8 is “not yet ready for production,” but serves as “a dedicated testbed for technologies that will shape a future RUF model.” Translation: this engine absolutely shows up in a production car eventually. Ruf doesn’t build test mules just for Instagram. The company builds them because it’s working toward something real.
The question isn’t whether the flat-eight will make it to production. The question is what car it ends up in, and how much horsepower Ruf actually unleashes when it stops pretending to play it safe. Will it land in a next-generation CTR3? A completely new model? A hypercar that makes the current lineup look like entry-level sports cars? At this point, Ruf has proven it can do whatever the hell it wants, and nobody should be surprised by anything.
The Bigger Picture: What This Says About the Industry
In an era where most performance car builders are either going full electric or turbocharging four-cylinder engines to oblivion, Ruf just announced a hand-built flat-eight with a manual gearbox. That’s not just a contrarian move—it’s a statement. It’s Ruf saying that there’s still room in the world for cars that prioritize mechanical purity and driver engagement over practicality and efficiency.
Will this engine compete with faster hypercars? Probably not in any meaningful way. Will it sell in volume? Of course not—Ruf’s entire business model depends on extreme exclusivity. But what it does do is keep the possibility alive that you can still build something insanely, beautifully impractical in the modern automotive world. In a landscape of increasingly homogenized performance cars, that matters more than horsepower numbers.
The flat-eight is a flex, pure and simple. It’s Ruf reminding the world that some companies still have the resources, the guts, and the engineering chops to build engines that serve no purpose other than to exist and sound incredible. That’s worth celebrating.
- Ruf revealed a new twin-turbo flat-eight engine producing over 1000 HP and 737 lb-ft of torque at Goodwood Festival of Speed.
- The 4.8-liter B8 engine is completely in-house engineered and still in prototype form, housed in a lengthened CTR3 with a six-speed manual transmission.
- Ruf says the B8 isn’t ready for production yet, but will serve as a testbed for future production models—meaning expect this engine in a real car eventually.
