F1 Abu Dhabi Post-Season Test 2025: Inside Pirelli’s First Real Run With the 2026 Tyres

10 December 2025 · 17:11 GMT

The season didn’t end on Sunday. Not really. One more day in the desert. Fresh tyres. Mule cars. A grid divided between established names and the next wave waiting for their chance. Even newly crowned World Champion Lando Norris stayed on for one last run, sampling the 2026 compounds as the sport pivoted toward its next era. The F1 Abu Dhabi Pirelli 2026 Tyres programme took centre stage as Pirelli closed out 2025 with the first full public run of its new range on the Yas Marina surface. It wasn’t about lap time. It was about understanding the architecture of the season ahead. Smaller tyres. Wider compound gaps. Aero that changes state. And the final outing for the 2025 cars before they disappear for good.

  • Paul Aron, Kick Sauber
  • Kush Maini, Alpine

All ten teams ran cars. All drivers listed above appeared in Pirelli’s official test release.


What This Test Actually Was

Two test groups.
Two different purposes.

Official drivers, including new champion Lando Norris, sampled Pirelli’s finalised 2026 compounds on adapted mule cars. Most cars were capped at 300 km/h to emulate next year’s reduced-downforce window. A few ran unrestricted using early straight-line mode.

Straight-line mode is the foundation of 2026 active aero.
Front-wing drag is shed on the straights.
Downforce returns for the braking zones.
Pirelli needed data across both aero states.

Young drivers stayed in 2025 chassis without restrictions, giving teams a final clean reference before the regulations retire.

Across nine hours, the grid logged 2,648 laps and nearly fourteen thousand kilometres.

What’s New for 2026

Sidewall Identity

Updated design featuring a chequered-flag motif.
Compound colours unchanged.

Reduced Dimensions

• Front width −25 mm
• Rear width −30 mm
• Diameter reduced by 15 mm (front) and 10 mm (rear)
• 18-inch wheel retained

A smaller footprint tightens the operating window and increases thermal sensitivity.

Compound Structure

C1 to C5 return, spaced wider for more strategic variation.
Homologation arrives December 15.

Headline Times and Who Did What

Kimi Antonelli topped the mule-car group with a 1:25.170 on C5. Piastri and Hamilton followed. Norris completed a structured run plan focussed on compound comparison and long-run behaviour rather than single-lap pace.

Sainz, Lawson, Gasly and Bortoleto delivered the bulk of the mileage beneath the front-runners. Fred Vesti put 145 laps on the 2025 car, the heaviest load in the outgoing spec.

Jak Crawford set the outright fastest time of the day with a 1:23.766 in the 2025 car before stopping early.


Pirelli’s Technical Read

Mario Isola described the day as a confirmation exercise.

All year, teams sampled isolated prototype components. Construction changes. Tread variations. Heat-flow tweaks. Abu Dhabi was the first time the full 2026 range ran together in a consistent environment.

Pirelli focussed on:
• Compound spacing performance
• Long-run degradation mapping
• Graining exposure linked to a reduced footprint
• Overheating tendencies in straight-line mode
• Load-transition characteristics as aero states change

The smaller contact patch is the most significant variable. Higher load density increases the risk of graining and temperature spikes. Today’s work tested whether the new casings prevent that.

Isola said the numbers align with modelling and will feed into homologation. Barcelona, not Abu Dhabi, will show the final truth once the 2026 cars run.

Team Voices and Early Readings

Teams spoke quietly. The engineering patterns were louder.


Mercedes

Antonelli’s 156 laps targeted tyre-load mapping.
Vesti’s 145 laps built the simulator–track correlation loop.
Andrew Shovlin outlined the logic: reduced-downforce configurations, setup sweeps to provoke tyre response, and nearly 1,600 km of data.

Mercedes leave with the most complete tyre model heading into winter.


McLaren

McLaren kept the messaging minimal.
Norris and Piastri focussed on compound comparison and validating transitions rather than chasing times. Internally, the team treated the day as a correlation benchmark for 2026 development.

McLaren leave with matched tyre references for both drivers ahead of winter.


VCARB

Lawson’s 141 mule-car laps produced one of the test’s most useful degradation curves. His “very different feeling” comment hints at significant mechanical changes tied to the reduced footprint.

Lindblad’s 139 laps in the 2025 car centred on procedural fluency, not performance. His early stop didn’t affect the programme.

VCARB exit with early clarity on tyre behaviour and integration processes.


Alpine

Gasly’s 144 laps gave Alpine a complete compound map in a single environment.
Maini’s 128 laps produced consistent, structured feedback on his first full official day.

Dave Greenwood merged both into one engineering picture.

Alpine leave with stable tyre data and confidence in their driver feedback loop.


Kick Sauber

Bortoleto worked on the C5.
Hülkenberg worked on the C4.

Two compounds. Two data points. One early baseline for their 2026 aero model.

Kick Sauber leave with a reliable soft-to-mid reference for winter simulation.




Coffee Corner Take

This was the first time the 2026 ecosystem ran in the open.
Smaller tyres. Aero that switches character down the straights. Load patterns that change how drivers build temperature and how engineers build stints. Abu Dhabi didn’t give us a spectacle. It gave us a preview.

Mercedes and Alpine left with the cleanest tyre profiles.
Two teams that structured the day around data integrity rather than pace, and ended up with compound maps that will matter when the 2026 cars fire up in January.

McLaren’s value came from continuity.
Norris and Piastri ran controlled, methodical programmes aimed at correlation, not benchmarks. Nothing dramatic. Nothing wasted. Just a calm confirmation of direction heading into a title-defence winter.

VCARB and Kick Sauber treated the day as foundation work.
Lawson’s long runs, Lindblad’s procedural build, Sauber’s split C4/C5 approach. All sensible early steps for teams that need stable baselines more than headline numbers.

And the young drivers closed the ground-effect era with one final set of clean reference laps. These cars won’t run again. Their numbers now exist only for comparison when 2026 begins.

Barcelona will show the truth.
Today showed the outline.
