Honda reveal F1 power unit in Aston Martin 'works' partnership celebration

Honda and Aston Martin have celebrated the start of its 'works' partnership in launch event in Tokyo, where the Japanese manufacturer's power unit was revealed. 

After several years with Red Bull, Honda has switched to Aston Martin for the start of Formula 1's new power unit regulations, which feature a 50/50 split between electrical power and internal combustion. 

It is a significant step for Aston Martin, who after only ever being a customer team now hold official 'works' status, due to the nature of its partnership with Honda. 

The event in the Japanese capital was attended by Aston Martin CEO Lawrence Stroll, Honda President Toshihiro Mibe and F1 President and CEO Stefano Domenicali.

"I am delighted to celebrate the start of our partnership with Honda here in Tokyo today," said Stroll. "Aston Martin Aramco Formula One Team and Honda share many values, and those values have brought us together for 2026 and beyond.

"The strong collaboration between the AMR Technology Centre at Silverstone and Honda Racing Corporation (HRC) in Sakura demonstrates the depth of our partnership. We are confident that we have all the elements required to fight for victory in the future and we have tremendous faith in Honda’s Power Unit and the engineers behind it. 

"Our journey won’t always be easy and challenges inevitably lie ahead, but winning is what drives both companies forward and together we look forward to many successful years of partnership."

As part of the event, Honda's newest F1 power unit – the RA626H – which will only be used by Aston Martin was unveiled. 

The brand has been working with Aston Martin and its key partners Aramco and Valvoline ahead of the new season, with key input from chief strategy officer Andy Cowell.

"Honda’s participation in F1, the pinnacle of automobile racing, has been the embodiment of the spirit of the company founder, Soichiro Honda, who inspired Honda engineers to commit to becoming No.1 in the world and to take on the most difficult challenges," said Mibe.

"In 2026, F1 will undergo a major change in regulations for both the chassis and power unit. Honda sees F1 as a symbol of challenge and innovation, and HRC, the global racing arm of Honda, has developed the RA626H, the new power unit for the 2026 season, to meet those challenges. Striving to become number One in the world, Honda will continue to take on challenges together with the Aston Martin Aramco Formula One Team.

"Today we also launch a new H mark with a refreshed design, which Honda has adopted as the new symbol representing its automobile business. This new H mark symbolizes the transformation of Honda ‘s automobile business so it is an important moment for us."
