Alpine and Adrian Newey’s new Formula 1 team Aston Martin are the biggest winners from the aerodynamic testing restrictions reset that has kicked in ahead of a crucial 2026 development run
Alpine and Adrian Newey’s new Formula 1 team, Aston Martin, are the major winners following the reset of aerodynamic testing restrictions ahead of the crucial 2026 development run. The ATR system, introduced in 2021, now affects how teams prepare for a significant rules change for the second time. A development allowance based on championship position was included in the ATR, with the mid-season reset occurring between the Canadian and Austrian GPs. Teams had specific percentages of a baseline for windtunnel runs and CFD items post-reset before the Austrian GP.
Alpine’s drop from sixth to last triggered the largest ATR swing from 95% to 115%, giving them the biggest development allowance for the remainder of 2025. Aston Martin, despite a tough start, also benefited from the reset by going from eighth to having the challenge of improving their car’s competitive edge after a positive upgrade package at Imola. Williams, once a strong midfielder, experienced the most massive swing from 110% to 90% due to their stellar performance in 2025.
Mercedes, which came ahead through a strong one-three finish in Canada, experienced a shift from fourth in the championship last year to second during the 2025 reset. Despite these changes, teams like Williams adapted efficiently and did not see dramatic changes in windtunnel output, proving their ability to maximize resources effectively under the ATR limitations.
