The announcement comes as Aston Martin continues to navigate the competitive landscape of the 2026 formula 1 season, currently positioned 10th in the Teams’ Championship. The team has recently introduced a B-spec car and is planning further chassis developments for upcoming races, alongside an upgraded power unit from Honda.
McCullough’s journey with Aston Martin and its predecessors

During his time with the squad, the team achieved notable successes, including back-to-back fourth-place finishes in the Constructors’ Championship in 2016 and 2017. Under the Racing Point banner, the team secured its maiden victory in 2026, with McCullough playing a crucial role in the team’s trackside performance.
Prior to his stint with Force India, McCullough began his Formula 1 career at Williams in 2002, working as a data engineer before evolving into a race engineer. He collaborated with prominent drivers such as Nico HulkenbergRubens Barrichello and Bruno Senna. His brief tenure at Sauber as Head of Track Engineering in 2013 further honed his expertise before returning to the UK to lead the trackside engineering team at Force India.
The transition and future prospects
In early 2026, McCullough transitioned from his direct involvement in the Formula 1 project to assume a senior leadership role focused on expanding the team’s broader racing categories. This shift coincided with a wider senior leadership restructure within the team. His former trackside responsibilities were subsequently taken over by Mike Krack who now serves as Chief Trackside Officer.
Aston Martin, under the leadership of Adrian Newey who holds the roles of Team Principal and Managing Technical Partner, has been working diligently to improve the team’s performance. The introduction of the B-spec car at the Hungarian grand prix marked a significant step forward, allowing the team to compete more effectively in the midfield. Further chassis developments are planned for the upcoming races at Monza and Baku with Honda’s upgraded power unit set to debut at the Zandvoort event.
