FIA Outlaws Ferrari Exhaust Wing in 2027 Technical Clampdown

The FIA has updated its 2027 technical regulations to ban aerodynamic bodywork around the exhaust tailpipe, shutting down a development path first exploited by Ferrari on the SF-26. Though legal throughout the 2026 season, a new exclusion zone and tighter tailpipe support rules will prevent teams from gaining rear airflow advantages through this area next year.

Why it matters:

The ban targets a concept Ferrari engineered into its car architecture from the start, making it difficult for rivals to replicate. By packaging the rear crash structure and differential to accommodate a small exhaust winglet, Ferrari created a unique aerodynamic tool at the rear of the car. The FIA's intervention prevents the idea from becoming a grid-wide development focus, especially after Mercedes, McLaren, and Red Bull found their own versions using support structure loopholes.

The details:

• Ferrari's innovation: The small winglet debuted during 2026 pre-season testing in Bahrain, improving the rear airflow structure on the SF-26.
• Integrated design: The solution required specific rear-end packaging to create the necessary space, meaning it was never a simple bolt-on item for competitors.
• 2027 rule change: Article C2.3.7 introduces a strict exclusion zone around the exhaust, while revised tailpipe support wording closes a second development avenue.
• Rival adaptations: Mercedes, McLaren, and Red Bull developed their own interpretations during the season using exhaust support allowances to create smaller aerodynamic devices.

What's next:

Ferrari now faces a strategic decision over whether to continue running the device for the remainder of the 2026 campaign. During Austrian Grand Prix practice, Lewis Hamilton ran the exhaust wing while reserve driver Dino Beganovic trialed a configuration without it as the team gathered comparative data. The clampdown forms part of a broader 2027 regulation clean-up that also includes tighter controls on floor body stays, sidepod bodywork interactions, and suspension behavior.
