Ferrari Unveils Cutting-Edge Diffusor Winglet Design on SF-26
Ferrari's SF-26 has already generated significant buzz during pre-season testing, with the iconic Italian team rolling out an innovative diffusor winglet alongside its headline-grabbing rotating rear wing. The new aerodynamic component represents yet another technical advancement from the Scuderia as they prepare for the 2026 season.
The Ferrari SF-26 has quickly become one of the standout machines of pre-season testing, capturing attention for multiple reasons beyond its distinctive rotating rear wing design. Among the car's technical innovations is a sophisticated new winglet created specifically for the diffusor, which the Scuderia unveiled during testing.
This latest development underscores Ferrari's commitment to pushing aerodynamic boundaries as the team fine-tunes its challenger for the upcoming campaign. The diffusor winglet represents the kind of detailed engineering work that characterizes modern F1 development, where marginal gains in downforce and efficiency can prove decisive on track.
With both the rotating rear wing and this new diffusor component drawing scrutiny from competitors and technical observers alike, the SF-26 has already established itself as a car packed with innovative solutions heading into the season.

Full Regulation Text
Article C3.5.8
Floor Winglet
Chapter: C3
In Simple Terms
Teams can add small winglets to the floor of their car that stick out from the sides. These winglets can be slightly angled (up to 5 degrees) and moved a tiny bit side-to-side (up to 10mm) to help fine-tune how air flows around the car. They're a special exception to the normal floor rules and can have up to two different sections stacked vertically.
- Floor winglets are small aerodynamic devices exempt from standard floor regulations
- They can be rotated ±5 degrees around a vertical axis and moved ±10mm in height for adjustment
- Maximum of two sections allowed in any vertical plane
- Must comply with the RS-FLOOR-WINGLET specification and use a single hanger attachment
Official FIA Text
Floor Winglet exempt from Article C3.2.4, results from Trim and Combination of RS-FLOOR-WINGLET, Winglet Profile, and single Hanger. May be rotated ±5 degrees about Y-aligned axis and translated ±10mm in Z. Must have up to two sections in any Z-Plane below TRIM-SURFACE.
Article 3.5
Floor Regulations
Chapter: Chapter III - Bodywork
In Simple Terms
The floor is the key downforce producer in modern F1. Ground effect tunnels underneath the car create suction. Strict rules govern the shape and dimensions to ensure teams generate downforce in similar ways. This was the major change in the 2022 rules to help cars follow each other more closely.
- Ground effect is primary downforce source
- Venturi tunnels create low pressure
- Strict dimensional requirements
- No movable floor elements allowed
Official FIA Text
The floor must be designed to create downforce primarily through ground effect. Specific reference surfaces, Venturi tunnels, and diffuser dimensions are defined. The floor edges must conform to specified heights above the reference plane. No movable aerodynamic devices are permitted in the floor assembly.
Article C1.6
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.
