Tom McCullough to Depart Aston Martin at End of 2026 Season

Breaking: Tom McCullough to Depart Aston Martin at End of 2026

SILVERSTONE — In a move that signals the conclusion of a transformative era for the team, Performance Director Tom McCullough has confirmed he will leave Aston Martin at the conclusion of the 2026 Formula 1 season. The announcement marks the end of a 13-year tenure for one of the paddock’s most respected engineering figures, whose career at the Silverstone-based outfit predates the current Aston Martin identity, stretching back through the Racing Point and Force India eras.

A Decade of Evolution

McCullough’s departure is the latest in a series of significant structural shifts at Aston Martin. Having joined the organization in 2014, he was instrumental in the team's rise during the Force India years, where his trackside leadership was a cornerstone of back-to-back fourth-place finishes in the Constructors’ Championship in 2016 and 2017. He remained a constant during the team’s transition into Racing Point—including the squad's breakthrough 2020 victory—and subsequently into the Aston Martin nameplate in 2021.

As part of a comprehensive management restructuring in early 2025, McCullough transitioned away from direct Formula 1 trackside operations. At that time, he stepped into a broader leadership role within Aston Martin Performance Technologies, focused on the expansion of the team’s racing categories outside of the Grand Prix paddock. His former trackside responsibilities were subsequently assumed by Mike Krack, who moved into the role of Chief Trackside Officer.

Impact on the 2026 Season

While McCullough has spent the last 20 months focused on these broader motorsport programs, his exit leaves another void in the senior leadership structure at a critical juncture. Aston Martin is currently fighting to climb from its difficult position in the Constructors’ Championship, where it sits 10th after 11 rounds.

The team, now under the stewardship of Adrian Newey as Team Principal and Managing Technical Partner, has been aggressively seeking to reverse its fortunes. Following the introduction of a B-spec chassis at the Hungarian Grand Prix and continued collaboration with Honda on power unit optimizations, the organization is looking to stabilize its operations both on and off the track.

What Comes Next

The departure of such a long-standing veteran, who holds over two decades of F1 experience including prior stints at Williams and Sauber, leaves an immediate question regarding succession and the long-term consolidation of the team’s management. While there has been no official statement regarding a direct replacement for his Performance Technologies role, the team is clearly prioritizing a period of sustained stability as it attempts to climb back up the grid hierarchy.

For now, McCullough remains with the team through the remainder of the 2026 calendar, providing continuity as the squad targets further performance gains at upcoming races in Monza and Baku.
