They call it the Erprober. Tester, in English. It sounds like a warning. A prototype sitting on the hallowed turf of Goodwood, waiting for you to look wrong at it.
This is a Ruf. The storied Porsche tuners aren’t hiding this thing in a garage anymore. They brought it out. Wild new supercar. Twin-turbo flat-eight. 1000-plus horsepower if you believe the claims, though they put the number at 986bhp specifically. Why shy away from round numbers? Mystery, maybe.
The engine sits in the rear. Horizontally opposed. Like every 911 you’ve ever owned. But bigger. Four liters and eight hundred liters of capacity later. 4.8 litres of displacement. That is two more cylinders than the standard setup. More chaos.
Torque figures? 737 lb-ft. It pulls the ground off your feet. Or would if you had brakes for it.
Ruf calls the B8 a testbed. Not production ready. Just yet. “It serves as a dedicated testbed,” they said. “Long before the world sees them.” That is how German engineers work. They build the thing in their heads. Then in the bay. Then they tell you about it at Goodwood. A new chapter. Or just a very loud paragraph.
The chassis looks like the CTR3. Because it is the CTR3. Just longer. By 100 millimeters. They stretched the tub to fit the block. No hiding spot here. The body is pure clue. It wears Blossom Yellow. Nodding to the Yellowbird. The CTR. The Nurbürgring killer from the past. It pays homage to its own lineage. Smart branding. Or maybe just vanity.
Transmission details are sparse. A six-speed manual sends that power to the rear axle. Will the final car keep it? Who knows. Manuals are dying elsewhere. But here? In Ruf? You bet your bottom dollar they want you shifting. Or not. Silence is also a strategy.
Porsche tried this before. You know this. They made the 904 concept. Meant to succeed the 918 Spyder. A 5.0-liter flat-eight. It never came. It sat there. Beautiful. Useless. Now Ruf picked up the sketchbook. And kept writing.
Why eight? Six is fine. Eight is obsession.
It makes a noise you probably haven’t heard from the rear of a street-legal car. A low howl. Distinctive. Unapologetic.
This is not the finished product. The finish line is miles away. But the engine is running. It’s here. It’s loud. And it’s waiting to see if the world cares about a horizontal engine that refuses to stay in a box of six.
They said it was a test.
It looks like a declaration of war on convention.
What happens next?
No one said.
