Overview
- Ferrari ran the rotating rear wing only in Friday practice at Shanghai before reverting to its Melbourne‑spec rear wing for sprint qualifying and the rest of the weekend, with reporters citing reliability concerns.
- Autosport reported the team lacked guarantees to race the device and judged the expected gain insufficient to justify the risk, with further analysis scheduled back at Maranello ahead of the Japanese Grand Prix.
- Lewis Hamilton said the part was rushed forward from a later target, that only two examples were available, and that it would return once the team is confident it is ready.
- The concept flips the rear‑wing flap roughly 180 degrees to create a low‑drag profile and clean diffuser airflow to boost straight‑line speed.
- Separate from the rotating wing, Ferrari retained a new FIA‑filed halo‑pillar winglet that delivers a small load benefit, and Haas ran a milder version of the exhaust/rear‑wing idea enabled by Ferrari’s architecture.
