'Key Aston Martin figure is set for departure at the end of the season'

McCullough has been an important figure at the Silverstone-based team. He joined the outfit in 2014, when it was still known as Force India, and remained through its years as Racing Point and its transformation into Aston Martin. Before that, he worked at Williams as a race engineer for Rubens Barrichello and Nico Hulkenberg, before spending a brief spell at Sauber in 2013.

McCullough became the Formula 1 team's performance director in 2018 and served in the role until the end of 2024. He was a key figure within the team and was responsible for setting up the cars in the best possible way during race weekends.

Following Aston Martin's reorganization in 2024, in which Andy Cowell was promoted to team principal and replaced Mike Krack, the Luxembourger took over many of McCullough's responsibilities. Afterward, McCullough continued his work as performance director for Aston Martin Performance Technologies over the following months, overseeing various projects.

It is currently unclear who will succeed McCullough, or whether Aston Martin will appoint a direct replacement.

Fernando Alonso has confirmed that he will definitely not change teams at the Hungarian Grand Prix. However, he explained that he will continue in Formula 1 if the current cars and regulations can still give him the adrenaline he needs.

He said: "I feel fresh, I feel motivated, I feel fast, but I need to enjoy what I do as well. As I said in Spa, I think the Silverstone Grand Prix and Spa were not fun to drive. I think it’s not fun to watch, it’s not fun to drive, and we’ve been repeating the same thing every single Grand Prix.
