Ferrari's Innovative Rear Wing Leaves Hamilton Sidelined During Bahrain Test Session
Lewis Hamilton encountered significant downtime during the second day of testing at Bahrain after Ferrari introduced a novel rear wing modification to their 2026 challenger. The disruption prevented the seven-time world champion from completing a full day of running as the Scuderia worked through issues related to their latest aerodynamic innovation.

The opening stages of Bahrain's F1 testing program saw Lewis Hamilton's day derailed when Ferrari rolled out an experimental rear wing design during his second outing in the new machinery. The fresh aerodynamic concept proved problematic, with an extended stoppage forcing the team to pause running while they addressed complications that emerged from the debut of the modification.
Hamilton found his track time significantly curtailed as a result of the technical hiatus, limiting his opportunity to build familiarity with the Prancing Horse's 2026 specification car during what was intended to be a productive session. The unexpected pause highlighted the challenges that come with introducing new components mid-testing, as Ferrari prioritized understanding the new rear wing's behavior and resolving the issues it presented.
The timesheet implications of the disruption remained notable as teams continued their development evaluations throughout the day at the Sakhir circuit. For Hamilton and Ferrari, the session served as a reminder of the complexities involved in introducing cutting-edge aerodynamic solutions, even during controlled test environments where engineers can gather crucial performance data for future refinement.

Full Regulation Text
Article C3.11.1
Rear Wing Profiles
Chapter: C3
In Simple Terms
The rear wing must fit within a specific design area and can have up to three separate sections. It cannot have inward-curving surfaces visible from underneath, and any inward curves visible from above must have a minimum radius of 100mm to ensure safety and fair aerodynamic performance.
- Rear wing bodywork must stay within the defined RV-RW-PROFILES design box
- Maximum of three non-overlapping sections allowed in the rear wing structure
- No concave (inward-curving) surfaces allowed when viewed from below
- Any concave surfaces visible from above must have at least 100mm radius to prevent sharp curves
Official FIA Text
Rear Wing Profiles Bodywork must lie in its entirety within RV-RW-PROFILES, comprise of up to three non-intersecting simply connected volumes, and contain no concave radius of curvature visible from below and no concave radius less than 100mm visible from above.
Article 30
Rear Wing Profiles Reference Volume (RV-RW-PROFILES)
Chapter: C
In Simple Terms
This regulation defines the maximum allowable space (or 'reference volume') where a Formula 1 car's rear wing can be positioned and shaped. Think of it as an invisible 3D box that the rear wing must fit within, with one angled plane cutting through it to set the upper boundary. If a team's rear wing extends beyond this box, it violates the rules.
- The rear wing must fit within a defined rectangular box measuring 465mm long (X-axis), 575mm wide (Y-axis), and 155mm tall (Z-axis)
- An additional angled plane cuts through this box, removing the upper portion and creating a sloped upper limit for the wing profile
- This volumetric restriction ensures all cars have comparable rear wing dimensions and prevents unfair aerodynamic advantages
- Teams must design their rear wing profiles to stay entirely within this reference volume during technical scrutineering
Official FIA Text
RV-RW-PROFILES is an axis-aligned cuboid [XR=165, 0, 725] to [XR=630, 575, 880], trimmed with plane passing through three points with all material below discarded.
Article C3.18.14
Rear Wing Skins
Chapter: C3
In Simple Terms
F1 rear wings must be rigid enough that their outer surfaces don't bend more than 2mm when a suction cup applies a pulling force to them. This test ensures wings stay stable and maintain their aerodynamic shape during races, preventing teams from using flexible wings as an unfair advantage.
- Rear wing skins can deflect no more than 2mm under 60N of force applied perpendicular to the wing surface
- A 50mm diameter vacuum cup is used to apply the test force
- Deflection is measured at the outer edge of the cup and compared to the lower wing surface at the same position along the wing
- The measurement point must be at least 300mm away from other reference points to ensure accurate testing
Official FIA Text
Skins of Rear Wing Profiles may deflect no more than 2mm when 60N force applied normal to and away from element. Force applied using vacuum cup of 50mm diameter. Deflection measured at outer diameter of cup and relative to lower wing surface at same X-Station, at least 300mm away.
