Aston Martin loses McCullough as former F2 champion Pourchaire joins Formula E

Tom McCullough will leave Aston Martin at the end of the 2026 season, closing out a 13-year stint that began in the Force India era and continued through the Racing Point rebrand. His exit comes as the Silverstone team reshapes its leadership under Andy Cowell. Separately, 2023 Formula 2 champion Theo Pourchaire has joined the Opel GSE Formula E Team for the upcoming campaign, calling it the biggest single-seater opportunity of his career.

Why it matters:

McCullough's departure removes a veteran engineering presence just as Aston Martin tries to convert heavy investment into consistent front-running form. The reshuffle under Cowell has already redistributed many of his former duties, signaling an operational break from the past. For Pourchaire, the move marks a decisive pivot away from the F1 ladder, placing him at the heart of Opel's entry during the disruptive Gen4 era.

The details:

• McCullough served as performance director from 2018 through 2024 before shifting to Aston Martin Performance Technologies.
• The Briton previously worked as a race engineer at Williams for Rubens Barrichello and Nico Hülkenberg and spent a brief stint with Sauber in 2013.
• Pourchaire's deal places him in Opel's Formula E squad ahead of Gen4 regulations, which introduce permanent all-wheel drive, up to 600 kW in qualifying and Attack Mode, and top speeds exceeding 335 km/h.
• The Frenchman believes the package suits his driving style, citing the increased power, four-wheel-drive layout and rapid acceleration.

What's next:

Aston Martin must fill a significant institutional void as it develops its 2027 challenger. The team has already begun absorbing McCullough's former trackside responsibilities. In Formula E, Pourchaire faces the challenge of adapting to a new discipline while helping Opel establish credibility from the outset of a major technical reset.
