QuoteDesigned to operate on hydrogen fuel, it offers 60% efficiency, far surpassing traditional internal combustion engines that operate at only 20–40%. Even more astonishingly, it does so while emitting mainly water vapor, a stark departure from the carbon-heavy byproducts of conventional gasoline engines.

Astron's H2 Starfire is compact, powerful, and low-maintenance. Built with fewer than 100 parts, it eliminates much of the friction that hampers traditional engines, requiring fewer repairs and boasting an operational lifespan exceeding 100,000 hours between overhauls. With nearly instantaneous throttle response, this engine promises a future where performance meets sustainability.
