GFG Style Peralta D Is a Copper One-Off Built for a Collector’s Daughters

The GFG Style Peralta D is a hand-hammered copper one-off built for collector Carlos Peralta's daughters, based on the Maserati GranTurismo.

GFG Style just unveiled its second one-off for Mexican collector Carlos Peralta. It might be the most striking car of the year. The Peralta D debuted October 24 at the Pasteje Automotive Invitational in Mexico. Like the Peralta S before it, it is a car built around a family story rather than a spec sheet.

The D is for Peralta’s daughters. Donne, in Italian. The S, revealed in 2025, honored his sons. Both cars come from GFG Style, the Turin studio Giorgetto and Fabrizio Giugiaro founded in 2015. Both start from a Maserati.

Built for his daughters

The Peralta S, shown in 2025, used the Maserati MC20 as its base. GFG Style dedicated it to Peralta’s sons. Its body used mirror-polished aluminum. The D moves to the Maserati GranTurismo as its base. It honors his daughters. Copper is its signature material. A second commission from the same patron is the strongest endorsement a design studio can get. The D reads as a deliberate counterpart to the S rather than a sequel. It offers the same idea, a different metal, and a different branch of the family.

Copper body, glass canopy, no doors

Every lower body panel on the Peralta D is hand-hammered from pure copper. GFG Style laid the copper over a carbon-fiber structure on an aluminum chassis. Above the beltline, the car is almost entirely copper-tinted mirrored glass. Its greenhouse reflects its surroundings the way the copper body catches light.

There are no doors, and no door handles. The entire front canopy, windshield, roof, and side glass together, tilts forward for front-seat access. That idea echoes the 1963 Corvair Testudo and the Peralta S itself. Rear passengers get in through gullwing panels that open along the car’s spine. That detail nods to Giorgetto’s 1967 De Tomaso Mangusta. The wheels are anthracite-black and geometric. Their 1970s-inspired design suits the car’s retro-futurist stance.

Copper is a strange choice for a car body, and that is why it works. It is heavy. It is soft. It demands handwork no stamping press can fake. Craftsmen shaped every panel on the D by hand. No two could ever be identical, even if GFG Style wanted to build a second one. It will not.

An interior with its own champagne service

Inside, the cabin is asymmetric. GFG Style trimmed it in metallic leather and Alcantara with copper-thread stitching. The passenger gets a makeup station with an illuminated mirror. Also, the rear console hides a retractable fridge. It holds exactly one champagne bottle and four copper glasses. It is the kind of detail that only makes sense on a car built for one person and his family. That detail tells you everything about who this car is for. It is not for a collector chasing lap times. It is for a father building something his daughters will remember.

What GFG Style is not saying

GFG Style has published no power figure, no weight, and no price for the Peralta D. The donor GranTurismo’s twin-turbo 3.0-liter V6 makes up to 543 horsepower in production form. However, the studio makes no output claim for this one-off. That is the point. The D is not a production car. It is not a concept for a show stand. It is not a design study shopping for a manufacturer. It is a completed commission, one of one, already in Carlos Peralta’s collection.

Coachbuilding used to mean exactly this. A designer, a patron, and a car that exists because one person asked for it. The Peralta D is copper and glass and champagne service. It is also a reminder. The wildest cars at any show are still the ones built for a single garage.
