jason castriota reimagines the porsche carrera GT as the carbon fiber JC9 supercar

Jason Castriota unveils coach-built JC9, a carbon fiber supercar

At the Miller Motorcars 50th Anniversary celebration, Legends, Jason Castriota reveals the JC9, a one-off supercar that reinterprets the golden age of endurance racing through a contemporary lens. Built as a special commission in collaboration with Miller Motorcars, the vehicle is based on the iconic Porsche Carrera GT and preserves the donor car’s naturally aspirated V10 engine and manual transmission. Fully clothed in a new carbon fiber body, the project marks the ninth automotive design in Castriota’s career, lending the car its name.

Drawing inspiration from the sports prototypes that dominated endurance racing between the 1960s and 1980s, the JC9 channels the dramatic proportions and aerodynamic purity of historic Le Mans competitors. Its sculptural bodywork wraps tightly around the Carrera GT platform, creating a low-slung silhouette defined by flowing fenders, deep side intakes, and a prominent rear wing. Finished in a pale blue livery accented by a bold orange center stripe, the car further references classic racing colors while establishing its own identity.

At the front, vertically stacked LED lighting elements replace conventional headlamp graphics, giving the vehicle a distinctive contemporary signature. The elongated nose, teardrop cockpit, and sharply tapered rear volume emphasize speed even when stationary, while extensive carbon fiber construction keeps weight low and performance uncompromised.

reimagining the carrera GT

Rather than creating a vehicle from a blank sheet, automotive designer Jason Castriota uses the Porsche Carrera GT as a mechanical foundation and conceptual starting point. Widely regarded as one of the most celebrated analog supercars ever produced, the Carrera GT’s six-speed manual gearbox and naturally aspirated V10 remain intact beneath the redesigned bodywork. The result is a machine that combines the tactile driving experience of an early-2000s supercar with a visual language rooted in motorsport history.

The bespoke cabin continues the custom approach with blue Alcantara-trimmed bucket seats, plaid inserts, exposed carbon fiber surfaces, and lightweight detailing throughout. The cockpit balances racing-inspired functionality with handcrafted finishes, reflecting the coach-built nature of the project.

The global debut of the JC9 forms part of Miller Motorcars’ Legends event, where the vehicle is exhibited alongside a selection of Jason Castriota’s most influential automotive works. Throughout his career, the designer has shaped projects including the Ferrari P4/5, Ferrari 599 GTB Fiorano, Maserati GranTurismo, Maserati Birdcage 75th, SSC Tuatara, Ford Mustang Mach-E, and Bertone Mantide.
