Honda Unveils RA626H Power Unit for Aston Martin's 2026 Works Return

Honda has officially pulled the covers off the RA626H, its new power unit set to propel Aston Martin’s AMR26 in the 2026 Formula 1 season. Unveiled at a high-profile launch in Tokyo, this engine marks the manufacturer's return as a full works partner, integrating chassis and power unit development for the first time since their championship-winning collaboration with Red Bull.

Why it matters:

This partnership signifies a massive technical reset for the sport and a strategic pivot for Honda as F1 enters a new era of sustainability. With regulations shifting heavily toward electrification, aligning with a factory team like Aston Martin allows Honda to pursue an integrated design philosophy—where the engine and chassis are developed as one—which is widely considered crucial for maximizing performance under the new 2026 rules.

The details:

• Technical Shift: The 2026 regulations feature a near 50/50 split between internal combustion and electrical power, a significant increase from the current setup. The RA626H is built to handle roughly three times the electrical output of current units while running on 100% advanced sustainable fuel.
• Integrated Approach: Aston Martin Executive Chairman Lawrence Stroll emphasized the "true works partnership," meaning the AMR26 chassis and RA626H engine are being developed simultaneously as a single, unified package rather than separate entities bolted together.
• New Branding: The power unit will sport a refreshed 'H' logo, symbolizing Honda's broader business transformation and commitment to motorsport. This branding will appear across Honda's global racing activities.
• Key Figures: The launch in Tokyo saw significant attendance from Honda Motor Co president Toshihiro Mibe, F1 CEO Stefano Domenicali, and Lawrence Stroll, underscoring the importance all parties place on this alliance.

What's next:

The on-track action is just around the corner. Aston Martin is scheduled to conduct a private test with the AMR26 at the Circuit de Catalunya on January 26, followed by the official car launch on February 9 ahead of pre-season testing in Bahrain.
