Ferrari is minimizing the weight penalty by installing a targa top made completely out of carbon fiber.
Aside from the obvious roof differences between the two models, the 812 Competizione A also has slightly lower flying buttresses compared to the coupe.Once the roof is up, Ferrari says the targa top creates a "sense of aesthetic continuity with the roll bars." Sticking with the coupe means you'll be getting a body-colored aluminum panel with carbon fiber elements at the back where it replaces the standard Superfast's elongated glass.
