From its hushed associations with Paul Walker to its ongoing Nürburgring lap efforts, the Porsche Carrera GT and its sonorous V10 are legends that still echo today.

Even more than 20 years after its debut, the model continues to command attention. Beyond making for an advanced display of Porsche engineering, it represents one of the last examples of the analog supercar era.

As a result, Carrera GTs are now typically the kinds of vehicles that are treasured, kept hidden away under lock and key so they’re safe in their appreciation. Not this one.

A reimagining of the Carrera GT

It’s called the JC9, and it’s a one-off effort that results from a collaboration between designer Jason Castriota and Connecticut-based Miller Motorcars.

If the design and livery look familiar, that’s because the dealership says the car takes inspiration from the 1960s prototype racers of old. In this instance, it’s especially evocative of Porsche’s own Le Mans-winning 917k.

As such, instead of the Carrera GT’s signature wide mouth and round lamps, the car now instead wears a low nose and a narrow grille. It also brings gull-wing doors, pronounced arches and exposed rear tires to cultivate the retro look.

When you consider it arrives with a full carbon fiber construction, it makes for a striking reinterpretation. It’s simultaneously fresh yet also old-school, a compromise that’s already drawn the ire of more than a few purists.

All the more because, though it’s unclear just how much Carrera GT remains throughout the car, you can nevertheless see some telltale signs of its influence.

Porsche DNA on proud display

Namely in the powertrain. At the rear of the JC9, you’ll find that Castriota and Miller Motorcars have left the legendary 5.7-liter V10 on full display.

Of course, that’s not without good reason. Porsche rated the engine for 605 horsepower, so even if completely stock, it was already packing plenty of giddyup from the factory.

Towards that end, it also looks as though the rear pushrod suspension shows itself from some angles. Why fix what isn’t broken, right?

Even the interior is very clearly of Carrera GT origin. From the center console and the seats to the signature gearshift, it’s proudly Porsche in its design.

When reimagined with eye-catching changes like royal blue sueded upholstery, orange stitching, vibrant seat belts and bright tartan, the result is something that’s bound to draw more than a few breaths from the Porsche faithful.

However, it’s precisely because it embraces some aspects of its DNA while also daring to be something new that the JC9 manages to be so striking. In spirit and design it transcends eras.

Availability and pricing

As a one-off design, the JC9 won’t be something you can buy anytime soon. Moreover, while Miller Motorcars didn’t publish a price, it must have cost a good chunk of change. For perspective, Carrera GTs typically trade for $2–3 million or more.
