Honda has officially launched its RA626H power unit set for the 2026 Formula 1 season. The engine will debut on Aston Martin's upcoming AMR26 chassis, marking a new technical partnership between the Japanese manufacturer and the British team.

The powertrain aligns with F1's updated electric-focused regulations, which aim to make engines more sustainable and road-relevant. Honda's return as a full power unit supplier expands its presence in the sport after previously exiting as a constructor in 2021.

Aston Martin revealed a plain green show car alongside the engine, signaling early development phase visuals. Team principal Mike Krack emphasized the importance of reliability and performance gains. Fans will watch closely for how the new Honda-Aston Martin combo challenges midfield competitors.
