Honda has acknowledged that its return to Formula 1 as a full power unit supplier may come with early challenges, as the Japanese manufacturer prepares to enter a new partnership with Aston Martin under radically different engine regulations.
From 2026, Formula 1 introduces a new power unit formula built around a near equal split between combustion and electric power. The regulations place far greater emphasis on energy management and electrical deployment, creating a steep learning curve for every manufacturer involved. Honda joins Audi, Ferrari, Mercedes and Red Bull Ford in developing an engine for the new era.
With rivals believed to have found advantages in specific areas of the rules, Honda has chosen to keep expectations realistic ahead of its on track debut.
“Of course, if we are going to compete, we are committed to winning,” said Koji Watanabe, president of Honda Racing Corporation, as the company revealed its new Formula 1 power unit. “However, the 2026 regulations are technically extremely challenging, and perhaps we will struggle.
“At this stage, before any on track testing, we don’t know the gap to our rivals, so we’ll have to wait and see once testing begins. In the long term, we aim to fight for championships.”
Focus on Areas of Concern
Honda has been open about where its concerns currently lie. While progress on the electrical side of the power unit appears steady, the internal combustion engine presents a tougher challenge.
“The electrification side is progressing as planned,” said Tetsushi Kakuda, Honda’s Formula 1 project leader. “However, that is not necessarily the case for the internal combustion engine.
“Ultimately, a lot depends on the amount of development time available. Taking that into account, we believe we have done everything we can to the fullest extent.”
Those comments underline how compressed development timelines have become under the cost cap and power unit freeze rules. Even with maximum effort, gains are harder to unlock quickly.
Aston Martin Factor
There is also uncertainty surrounding Aston Martin itself. Despite significant investment from owner Lawrence Stroll, the team has yet to establish itself as a consistent front runner since its origins as Jordan Grand Prix in 1991.
The upcoming AMR26 will be the first Aston Martin car to fully benefit from the team’s expanded Silverstone facilities. It will also be the first to incorporate the influence of Adrian Newey in a leadership role, adding intrigue to the project’s long term potential.
Looking Beyond the First Season
Honda’s comments point to a long view rather than immediate results. The manufacturer is clear about its ambition, but also realistic about the difficulty of matching established benchmarks straight away.
With new regulations, a new works partnership and major structural changes at Aston Martin, 2026 appears set to be a foundational year. For Honda, success may not be measured immediately by wins, but by progress, stability and the ability to build toward genuine title contention in the seasons that follow.
