While the rest of the world is accelerating into electric silence, somebody just bolted together a naturally aspirated V10 and a manual gearbox. And it wasn’t a factory — just a dealership.
America’s Miller Motorcars, based in Connecticut, marked its 50th anniversary the way only true diehards do — with a supercar of its own. The machine is called the JC9, and it’s built on a Porsche Carrera GT. But you’d never guess what’s underneath just by looking at it.
The project is the work of Jason Castriota — a designer with the kind of résumé you frame on a wall. Ferrari P4/5, Maserati Birdcage 75th, SSC Tuatara, Bertone Mantide. JC9 is his ninth major automotive project, hence the name. The new bodywork is entirely carbon fiber, and the silhouette throws you back half a century — straight to vintage Porsche racers, especially the legendary 917K, the short-tail that won Le Mans twice, in 1970 and 1971. That’s why the JC9 doesn’t read like a Carrera GT tuning job. It reads like a forgotten factory prototype that could’ve rolled out of Stuttgart fifty years ago.
The real secret, though, is inside. Open the door and the Carrera GT is right there. The gauges, the vents, the center console, the overall architecture of the cabin — all of it intact. The steering wheel is also familiar, just minus the Porsche badge.
The mechanicals, according to the announcement, came straight from the donor too. The 5.7-liter naturally aspirated V10 and the 6-speed manual — the exact pairing that still makes the Carrera GT one of the last true analog supercars. The original engine made 603 horsepower. No power bump has been disclosed for the JC9, and frankly, none is needed.
The JC9 was shown as a single, one-off build at the Miller Motorcars anniversary event, alongside other Castriota designs. Porsche has nothing to do with it officially. And that’s exactly the point: somebody took an iconic Carrera GT and turned it into a car Stuttgart itself never built.
