貴公司即將為新款汽車推出廣告活動，且想使用現有的 3D 汽車模型製作 3D 沉浸式廣告。 這時該使用哪種 Display & Video 360 廣告格式？

Swirl ads are the correct choice because they are designed for immersive 3D experiences, allowing users to interact with 3D models directly within the ad unit. This format is ideal for showcasing a new car model, as it enables viewers to rotate, zoom, and explore the vehicle from various angles. Parallax ads create a sense of depth but don't support interactive 3D models. Flipbook ads are for sequential image displays, not 3D interaction. Native ads match the look and feel of the surrounding content but don't inherently offer 3D immersive capabilities.
