• Castagna Milano, a small Italian coachbuilder, is proposing a stylish convertible based on the Alfa Romeo Giulia Quadrifoglio.
• The styling is drastically different, with sharp creases and fang-like LED headlights.
• The convertible is only a rendering for now, but Castagna Milano will build it as a one-off if a customer is willing to put up the cash.

The Alfa Romeo Giulia is still among the most beautiful cars available. Despite being on the market mostly unchanged since the 2016 model year, the Italian sports sedan’s styling has aged remarkably well, its smooth curves and piercing headlights creating a timeless elegance. But Italian coachbuilder Castagna Milano thinks it can improve on the Alfa Romeo’s look, whipping up a design for a new two-door convertible based on the Giulia Quadrifoglio.

The assertively styled convertible is only a render for now, but Castagna Milano says that it wants to turn it into a one-off creation if it can find an Alfa Romeo enthusiast who is willing to pay. And while the hard edges and crisp lines are quite a departure from the typical Alfa Romeo finesse, the two-door is striking enough that we think someone will raise their hand.

The car shares essentially nothing with the regular Giulia sedan, the only visual connection being the classic triangular Alfa Romeo grille, although it appears to be narrower here, and is attached to a carbon-fiber panel that stretches up and over the hood. The grille is flanked by dramatic headlights, consisting of a series of horizontal LED lines and a trio of LED fangs that shoot downward. The lights sit within a recessed section covered in vents to help cool the engine and front brakes.

The convertible has wider front and rear tracks, resulting in its confident stance, which is accentuated by the pronounced fenders. The beltline has been carved into the bodywork, with the cutout curving around to the rear end and housing the thin taillights. At the rear, stacked exhaust pipes sit on either side of the diffuser, and there’s an active spoiler above.

Castagna Milano says the bodywork would be fashioned completely from carbon fiber, and the cabin would be decked out with wood trim and two different types of leather. The seats have been shifted rearward by 13 inches to create more eye-catching proportions. The coupe would keep the Quadrifoglio’s twin-turbo 2.9-liter V-6 that produces 505 horsepower, but Castagna Milano claims the car would weigh 3130 pounds, around 700 pounds less than the regular Quadrifoglio.

This isn’t the first time we’ve seen a Giulia Quadrifoglio transformed into a sleek sports car. In 2022, Zagato built its own two-door Alfa Romeo, but the Giulia SWB Zagato wore more traditionally curvaceous styling, versus the jagged aggressiveness of Castagna Milano’s creation. For now, however, the Castagna Milano Giulia convertible remains a fantasy.
