Honda reveals first sound of 2026 F1 engine in dyno clip

Honda has become the first manufacturer to publicly reveal the sound of a 2026 Formula 1 power unit, releasing a 20-second dyno test clip labeled "our soundtrack for 2026." The audio offers the first tangible hint of what the next-generation engines will sound like, marking a significant moment as teams prepare for the new technical era.

Why it matters:

The 2026 regulations represent the biggest power unit overhaul in a decade, with a major shift towards electrical energy and the removal of the complex MGU-H. The sound of an F1 car is a core part of its identity and fan experience. Honda's early reveal breaks the usual secrecy surrounding engine development and provides the first clue about how the acoustic character of the sport might change.

The Details:

• The clip, posted on Honda Racing F1's social media, features the engine running through seven gears, accelerating down a straight, and then downshifting as it slows for a corner.
• With on-track testing of the new power units forbidden, the sound originates from dyno testing of the engine that will power the Aston Martin team starting in 2026.
• Compared to the current turbo-hybrids, the audio suggests a slightly different, potentially more raw engine note, attributed primarily to the removal of the MGU-H (Motor Generator Unit – Heat).
  • The MGU-H, which recovers energy from turbo heat, also acted as a muffler. Its absence is expected to alter the exhaust sound.
• Mercedes F1 engine chief Hywel Thomas previously noted the sound change would result from competing factors: less back pressure from the removed MGU-H might increase noise, while using less fuel might decrease it. He predicted the final result would be "really, really similar" to today's engines.

The Big Picture:

Honda's reveal is also a statement of intent and confidence as it embarks on a new works partnership with Aston Martin. After achieving championship success with Red Bull and briefly exiting the sport, Honda was drawn back by the 2026 rules' emphasis on electrification. Honda Racing Corporation president Koji Watanabe expressed a long-term championship vision for the partnership, citing the combination of Aston Martin's new facilities and passion with Honda's development prowess. While the competitive order for 2026 remains a mystery, Honda's early transparency suggests a team eager to showcase its progress and build excitement for its new chapter.
