In Formula 1, a struggling car leaves nowhere to hide from the stopwatch. Adrian Newey has now put a plain explanation on the Aston Martin F1 delay that left the team chasing from the start of the AMR26 project, saying Melbourne exposed how much ground had already been lost.
Newey joined Aston Martin from Red Bull in spring 2025 as managing technical partner, arriving with a reputation that immediately raised expectations. The AMR26 is the first car designed under his leadership for the team, but so far it has not matched the billing. Aston Martin has often sat near the bottom of the timing screens, which is a quick way for optimism to run into reality.
Why Aston Martin started behind its rivals
Newey said the team was compromised on both sides of the car: chassis and power unit. The bigger problem, he said, was a late start that left Aston Martin months behind rivals already working under the new 2026 regulations.
Rivals were able to put their designs into the wind tunnel from January 1, 2025. Aston Martin, by Newey’s account, did not begin serious work on the 2026 car until mid-March 2025 and did not get a model into the wind tunnel until mid-April.
"On both the chassis side and the power unit side, we've been on the back foot from the start," Newey told Aston Martin’s official team site. "In hindsight, we probably put too much expectation on ourselves, and of course, you must never forget the quality of the opposition you're up against across the grid."
He added that the late schedule created "a huge gap to close." In Formula 1, that is not a scheduling inconvenience. It is the difference between refining an idea and finding out in public that the idea needs refining.
What went wrong with the AMR26 build
The AMR26 has had problems with the Honda power unit, vibration, weight, and gearbox behaviour. Newey said the chassis is "quite a long way overweight," with some of that linked to integrating the power unit and managing the vibration issues that emerged with Honda.
He also accepted that Aston Martin had fallen short on its own work to reduce mass.
"When you design in a rush, weight is the first thing that suffers because you don't have the time to thoroughly optimise everything," he said.
That matters because extra weight hurts lap time everywhere: acceleration, braking, tire wear, and the way engineers can balance the car. In a field this tight, carrying too much mass is not a small accounting problem. It is a recurring bill paid every lap.
Fernando Alonso has also pointed to problems with Aston Martin’s new in-house gearbox, particularly in Miami and Monaco, where the car was losing gear synchronization at low speed. Those circuits demand drivability and slow-speed precision, so the timing could hardly have been worse.
Why Newey’s bold aero call carried risk
Newey also said Aston Martin chose an ambitious aerodynamic direction for the AMR26, and he made clear that he was a major force behind that choice.
"Aerodynamically, we also took a bold direction, which was largely pushed by me, without the luxury of exploring multiple concepts in depth because time was against us," he said.
He didn’t call the concept wrong, but said it created problems the team didn’t expect. That distinction matters. A flawed concept can sometimes be developed into competitiveness, while a fundamentally incorrect one can trap a team for far longer.
The problem for Aston Martin is that exploration time is valuable. Teams usually test competing ideas before committing to one design path. Aston Martin, by Newey’s telling, had to choose quickly, build quickly, and then learn from the consequences while everyone else was already moving.
The car has not received an upgrade since the start of the season. A major package is planned before the summer break, giving Aston Martin a chance to correct some of the AMR26’s weaknesses, though not to recover the time already spent firefighting.
Why Melbourne became the wake-up call
Newey said the Australian Grand Prix in Melbourne was the moment Aston Martin fully understood the scale of the problem. Because of power unit difficulties, the team’s first meaningful running came only in Free Practice Three.
Before that, testing had been heavily disrupted. In Barcelona and across the two Bahrain tests, Aston Martin spent too much time in the garage trying to make the Honda power unit work properly with the chassis and gearbox.
"Melbourne was the wake-up call," Newey said. "Because of various power unit challenges, our first proper running was actually Free Practice Three at the Australian Grand Prix."
That is late by any reasonable standard. It is especially late when the car is new, the power unit integration is complex, and the team is trying to validate a bold aerodynamic package. Aston Martin arrived needing data and instead spent crucial early mileage solving basic operational problems.
Newey summed it up bluntly: everything that could go wrong did go wrong. Put simply, Aston Martin’s 2026 project started late, got bogged down technically, and ran into rivals who never slowed down.
The major upgrade before the summer break now carries obvious weight, both literal and competitive. For Alonso, the engineers, and a team that hired Newey to raise its ceiling, the next step is less about reputation and more about making the AMR26 behave like a race car with a plan.
