Honda Racing Corporation has issued a statement on its Formula 1 engine programme, committing to enhance ongoing development work, according to Motorsport Week. The update comes six races into the 2026 season, Honda’s first year supplying power units under the new technical regulations.
2026 Power Unit Landscape
Honda supplies engines to two teams in 2026: Aston Martin and Red Bull Racing. The manufacturer developed its new-generation power unit at the Sakura facility in Japan, working to the revised formula that splits power output approximately evenly between the internal combustion engine and the hybrid system. The new regulations eliminated the MGU-H and increased the MGU-K’s contribution, creating fresh engineering challenges for all manufacturers.
The competitive order among power unit suppliers through the opening six races of 2026 has shown variation. Mercedes, Ferrari, Renault, Audi, and Honda are all navigating the first season under rules that prioritise electrical energy deployment and fuel efficiency. Early performance gaps have appeared in both qualifying and race trim, though development trajectories remain fluid.
Honda’s Development Timeline
The Japanese manufacturer’s pledge to enhance progress suggests active development work on reliability, performance, or both. Power unit homologation rules permit specific updates during the season, particularly for reliability improvements. Performance development follows a stricter token system, limiting the scope and frequency of changes.
Honda Racing Corporation’s previous stint in Formula 1 ran through 2021, when it supplied Red Bull Racing and AlphaTauri. The manufacturer withdrew after the 2021 season to focus on carbon neutrality goals but maintained technical collaboration with Red Bull’s in-house powertrain division. Its return as a full works supplier in 2026 marked a renewed commitment to the sport.
Impact on Customer Teams
Any enhancements to Honda’s power unit will directly affect Aston Martin and Red Bull Racing. Aston Martin switched to Honda power for 2026 after years as a Mercedes customer, while Red Bull Racing’s use of Honda engines dates to 2019. The two teams’ different chassis philosophies may extract different performance profiles from the same engine package.
Honda’s update statement, as reported by Motorsport Week, did not specify a timeline for the enhancements or identify particular areas of focus. The next opportunity to assess any changes will come at the Emilia Romagna Grand Prix at Imola, scheduled for May 18-20.
