Haas Adopts Ferrari's Exhaust Wing Technology Ahead of Chinese Grand Prix

Haas has integrated an advanced exhaust wing design into its car package, mirroring a recent innovation introduced by Ferrari. The modification will make its competitive debut this weekend at the Chinese Grand Prix.

Formula 1

Following Ferrari's introduction of a cutting-edge exhaust wing concept, Haas has elected to implement its own version of the technology for this weekend's Chinese Grand Prix. The move represents the team's decision to adopt the aerodynamic innovation that has caught the attention of the F1 paddock, with the American outfit bringing the upgraded component to the circuit in pursuit of improved performance.

The integration of this Ferrari-inspired design demonstrates how quickly competitive solutions can proliferate through the grid when teams identify performance advantages. By introducing the exhaust wing modification at this stage of the season, Haas aims to enhance its competitiveness as the championship progresses through 2026.

New systems or technologies

Chapter: ARTICLE C1: GENERAL PRINCIPLES

In Simple Terms

If a team invents a clever new system or technology that isn't explicitly mentioned in the rulebook but the FIA approves it, they can only use it for the rest of that season. Once the season ends, that innovation is no longer allowed unless it becomes an official part of the regulations.

New technologies must be approved by the FIA before use
Approved innovations are only permitted until the end of the season in which they're introduced
Teams cannot carry over one-season innovations to the next season automatically
The regulation prevents any team from gaining a permanent advantage from a loophole

Official FIA Text

Any new system, procedure or technology not specifically covered by these Technical Regulations, but which is deemed permissible by the FIA, will only be admitted until the end of the Championship during which it is introduced.

EC Rocket Aperture

Chapter: C3

In Simple Terms

F1 teams can have small exhaust outlets (called 'rocket apertures') on the engine cover to help with aerodynamics. These holes must be no bigger than 100,000mm² total and positioned toward the rear of the car, with a maximum of two holes allowed on each side.

Maximum total area of 100,000mm² for all exhaust apertures combined
Apertures must be located rearward of position XR = −55 on the engine cover
Teams can have up to two separate apertures per side (up to four total)
These are exhaust-only outlets with specific dimensional constraints [10, 300, 350]

Official FIA Text

EC Rocket aperture within [10, 300, 350] RV on Engine Cover, maximum 100000mm² area, efflux only, must lie rearward of XR = −55, may consist of up to two apertures per side.
