The Ferrari 12Cilindri's exterior design is inspired by the classic 365 GTB Daytona, with a long nose giving a retro feel but overall very clean and futuristic lines. The most iconic feature is the Delta Wing rear window, with small flaps on each side offering both low-drag and high-downforce modes – raising them increases downforce for greater stability.
Ferrari 12Cilindri 嘅外形設計靈感源自經典嘅 365 GTB Daytona，車頭較長帶有復古味，但整體線條非常簡潔科幻。車尾最標誌性嘅設計係 Delta Wing 三角窗，兩側細襟翼提供低風阻同高下壓力兩種模式，升起時可增加下壓力提升穩定性。
