What happened: Changes The revised car debuted during Friday practice at the Hungaroring.
Why it matters: Aston Martin entered the weekend at the back of the 2026 field after delaying development work for one concentrated push. The changes are designed to strengthen airflow beneath the car and support higher rear ride heights.
By the numbers: The FIA filing contains 16 updated areas. The revised AMR26 placed 13th in opening practice, 2.4 seconds off the fastest lap.
What to watch: Qualifying will provide the first low-fuel measure of the overhaul. Race pace and tire behavior will offer the broader test Sunday.
