2026 Starts Here: The Complete Guide to the Abu Dhabi F1 Post‑Season Test

This session provides the first collective on‑track trial of Pirelli’s new 2026 tyres. Far from being a routine end‑of‑year run, this Abu Dhabi test is a key milestone in the transition to F1’s next technical era.

Why the Abu Dhabi 2025 Test Matters

The 2026 regulations will bring a profound shift to Formula 1: revised chassis concepts, active aerodynamics, a rebalanced power unit formula, and increased use of sustainable fuels. Pirelli’s new range is being developed to match the different loads, speeds and aerodynamic characteristics expected from the 2026 cars.

The test is a rare opportunity for teams to begin correlating their simulations and wind‑tunnel work with real‑world behaviour on tyres designed for the upcoming ruleset.

Test Format: Mule Cars and Rookie Running

The 2025 Abu Dhabi test is structured around two distinct programmes that run in parallel:

• Pirelli 2026 tyre test with mule cars: Each team will field a modified version of its current chassis adapted to run the new 2026‑spec tyres. These cars are adjusted to better approximate the loads expected under future regulations.
• Rookie and young driver mileage: Teams are encouraged to run rookie or young drivers in a separate programme, using the test as a talent evaluation platform.

The New 2026 Tyres

Pirelli has outlined several key characteristics of the 2026 tyre range being evaluated:

• Reduced dimensions: Tyres are slightly smaller and narrower than the current 18‑inch specification to reduce drag and weight.
• Updated sidewall graphics: New designs signal the start of a new era.
• Compound range: Each team receives a controlled allocation (C2–C5) to evaluate behaviour across a wide performance window.

Technical Objectives: What Pirelli Wants to Learn

Pirelli’s priorities include mapping load and deformation, studying temperature management, and analyzing degradation profiles. The data will be combined with previous private tests to finalise construction choices for the new regulations.

What Teams Are Looking For

While officially a Pirelli programme, teams will focus on simulation correlation, set‑up sensitivity, and gathering qualitative driver feedback. Operational learning regarding out‑laps and safety‑car conditions will also be crucial.

Conclusion: The First Step into F1’s Next Era

The data gathered in Abu Dhabi will feed directly into the final development phase of the 2026 tyres. The Abu Dhabi post‑season test is more than a simple extension of the 2025 campaign; it is the first collective, tangible step into Formula 1’s next era.
