Honda Unveils RA626H Power Unit as Aston Martin Begins Works Era

Honda has officially launched its RA626H power unit in Tokyo, signaling a full-scale return to Formula 1 as an exclusive works partner for Aston Martin. This unveiling marks the start of a new era under the 2026 regulations, featuring a 50/50 split between combustion and electric power, with both parties aiming to leverage this integration to challenge for championships.

Why it matters:

This partnership transforms Aston Martin into a genuine works team, allowing for a fully integrated design between chassis and power unit. With high-profile signings like Adrian Newey and Andy Cowell, combined with Honda's new technology, the Silverstone squad is positioning itself as a leading contender to disrupt the current grid hierarchy.

The details:

• New Regulations: The RA626H is Honda's first engine under the 2026 rules, utilizing sustainable fuel and an equal split between internal combustion and electrical power.
• Exclusive Partnership: Aston Martin will be Honda's sole customer, effectively becoming a works team to facilitate closer collaboration.
• Leadership Vision: Honda CEO Toshihiro Mibe emphasized that the new regulations align with carbon neutrality goals, calling the effort a "battle with ingenuity."
• Integrated Approach: Lawrence Stroll highlighted designing the chassis and power unit as a single package, a strategy enabled by their works status and the technical leadership of Newey and Cowell.

What's next:

The AMR26 will hit the track for a private test at Circuit de Catalunya on January 26. The official car launch is set for February 9, followed by pre-season testing in Bahrain later that month, ahead of the season opener in Australia on March 8.
