Miller Motorcars is marking its 50th anniversary with a distinctive one-off supercar.
It is named the JC9 and draws from the Porsche Carrera GT.
The design emerged from work with Jason Castriota, an automotive designer recognized for the Ferrari P4/5 and other notable projects.

Luxury dealerships seldom choose to craft a bespoke supercar, yet Connecticut's Miller Motorcars has pursued this path. The firm worked with automotive designer Jason Castriota to create the JC9, which is based on the Porsche Carrera GT and evokes a machine that could have lined up against the 917K more than five decades ago.

Per the announcement shared on social media, the JC9 debuted officially last weekend as a coachbuilt V10 manual supercar constructed entirely from carbon fiber. Its exterior departs from the Carrera GT donor vehicle, though the interior tells a different story.

The cabin replicates the original exactly, with matching gauges, dashboard vents, and center console. The steering wheel appears unchanged except for fresh trim that omits the Porsche emblem. It remains unknown whether the GT's naturally aspirated V10 delivers extra output beyond its original 603 horsepower and 435 pound-feet of torque from two decades ago.

The vehicle premiered during the dealership's 50th anniversary event. The JC9 appeared alongside other Castriota designs including the Ferrari P4/5, the Ferrari 612 Kappa, the Maserati Birdcage 75th, the SSC Tuatara, the Ford Mustang Mach-E, and the Bertone Mantide.

Motor1's Take: Although rooted in the Carrera GT, the JC9 benefits from Castriota's striking redesign that stands as a genuine one-off worthy of Porsche itself.
