## Alfa Romeo Giulia Quadrifoglio Convertible
Italian coachbuilder Castagna Milano plans to transform Alfa Romeo Giulia Quadrifoglio into a two-seat convertible with carbon-fiber bodywork.
## Peugeot-Like Front End
The proposed front end features fang-like daytime running lights resembling Peugeot's styling with angular Y-shaped elements.
## Carbon Fiber Bodywork
Castagna Milano envisions extensive carbon-fiber bodywork with a dramatically elongated hood and lower position.
## Cabin and Luggage Space
The convertible would offer wood trim, leather, new glass, and 623 liters of luggage space with fabric top folded.
## Weight and Engine
The proposed convertible targets 1,420 kilograms weight with Alfa Romeo's 2.9-liter twin-turbo V6 engine.
## Cruising Efficiency
Castagna Milano promises a longer final-drive ratio for improved cruising efficiency without engine changes.
## Digital Design Only
The Giulia Quadrifoglio cabriolet exists only as a digital design proposal with no physical car built yet.
## Why Not Build It?
Castagna Milano needs a customer with deep pockets to commission the one-off project before it becomes reality.
## Key takeaway

Castagna Milano plans a carbon-fiber Alfa Romeo Giulia Quadrifoglio convertible with Peugeot-like styling, targeting 1,420kg weight and 623 liters of luggage space.
