Audi Unveils Bold Sidepod Evolution for 2026 Campaign During Bahrain Test
Audi has introduced a dramatically redesigned sidepod configuration on its R26 chassis for the Bahrain testing phase ahead of the 2026 season, marking a significant departure from the more traditional design philosophy displayed during the Barcelona shakedown. The German manufacturer's new approach signals an aggressive aerodynamic development strategy as it prepares for the year ahead.
The Audi R26 arrived at Bahrain's Formula 1 testing with a notably revised sidepod geometry, representing a substantial evolution from what the team had previously showcased during Barcelona's initial running ahead of the 2026 season.
During the Barcelona shakedown, Audi had implemented a more conservative design philosophy. The sidepods featured an inlet with a subtle overbite and adopted an inwashing approach, with the rear sections tucked inward to manage aerodynamic flow characteristics.
However, the Bahrain test revealed a complete rethinking of this strategy. The new sidepod configuration departs dramatically from Barcelona's conventional blueprint, suggesting Audi has identified significant development opportunities during the early testing phase.
This radical redesign underscores the team's commitment to pushing aerodynamic boundaries as the 2026 season approaches. The shift from Barcelona's more measured approach to Bahrain's aggressive new design indicates that Audi is actively pursuing performance gains through bold engineering solutions rather than incremental refinement.
Such substantial modifications between test sessions highlight the competitive nature of Formula 1 development, where teams continuously evaluate and evolve their technical packages in pursuit of performance advantages. Audi's willingness to embrace this dramatic sidepod revision demonstrates the team's adaptive approach heading into the new season.

Article B11
TRACK RUNNING OUTSIDE A COMPETITION
Chapter: B
In Simple Terms
When F1 teams want to test their cars outside of official races (like in practice sessions, tire tests, or driver evaluation sessions), they must tell the FIA and other teams at least a week ahead of time. This ensures everyone knows about the testing activity and maintains fairness across the sport.
- Teams must notify the FIA and competitors at least 7 days before any non-competition track running
- Covers various testing types including TCC (Tire Compliance Check), TPC (Tire Performance Check), DE (Driver Evaluation), PE (Performance Evaluation), TMC (Tire Monitoring Check), and substitute driver tests
- Applies to all track activity outside of official race competitions
- Advance notification ensures transparency and equal knowledge among all competitors
Official FIA Text
Provisions for track running outside official competitions including TCC, TPC, DE, PE, TMC and substitute driver tests. Competitors must inform FIA and other competitors of planned activities at least seven days in advance.
Article C3.8.3
Rear Bodywork Assembly
Chapter: C3
In Simple Terms
The rear bodywork of an F1 car (the sidepods and engine cover) must form one continuous, solid shape with no gaps, overlaps, or disconnected sections. Think of it like clay that's been molded into one unified piece rather than separate parts stuck together.
- The sidepods and engine cover combine to create the rear bodywork assembly
- Must be a single, simply connected volume with no separate or floating sections
- Cannot have overlapping regions - parts cannot occupy the same space
- Once fully defined, the shape must be valid and properly connected
Official FIA Text
Rear Bodywork Assembly results from the Trim and Combination of Sidepod and Engine Cover. Once fully defined, it must be a single, simply connected volume, with no overlapping regions.
Article B6.6.5
Test parts, Test Software, Component Changes & Set-up Changes
Chapter: B6
In Simple Terms
Teams can test new parts and software during official tyre tests, but the car's basic setup must stay the same throughout the test. They can only make changes to the car's mechanical setup, driver controls, or software if it's absolutely necessary to properly test the tyres or complete the test.
- Test parts and test software are allowed during tyre tests
- The car must maintain a fixed specification, configuration and setup
- Mechanical setup changes are only permitted if necessary for tyre evaluation
- Any component or software changes must be justified by tyre testing requirements
Official FIA Text
Test parts and test software are permitted. However, the Car must remain in a fixed specification, configuration and set-up. Mechanical set-up changes, driver control changes, software and component changes are only permitted if necessary for correct evaluation of tyres or to complete the tyre test.
