Aston Martin and Honda's F1 Partnership: Challenges and Opportunities.

Aston Martin's decision to switch to Honda power units in 2026 was driven by the desire to be in charge of its own destiny in terms of power unit supply, according to Aston Martin Performance Technologies CEO Martin Whitmarsh. The move will allow the team to fully integrate its chassis and power unit packages, which is seen as crucial under the next set of regulations. The decision also takes away the necessity to share a power unit and other associated parts with a key rival, which creates an "incompatibility," according to Whitmarsh.
