Hirth Engines and ePropelled Announce Strategic Collaboration to Advance High‑Efficiency Propulsion Systems

Hirth Engines, a German manufacturer of two‑stroke engine technology, and ePropelled, an innovator in high‑efficiency, intelligent electric propulsion and power‑generation systems, announce a strategic collaboration aimed at delivering the next generation of hybrid propulsion solutions for the UAV, aerospace, defense, and specialized mobility markets.

Driven by increasing demand for reliable, lightweight, and energy‑efficient propulsion systems, the partnership brings together Hirth’s decades‑long expertise in advanced combustion engines with ePropelled’s pioneering electric propulsion and power‑management technologies. Together, the companies will develop integrated hybrid systems designed to offer unmatched performance, extended mission endurance, and greater operational flexibility.

Under this collaboration, Hirth Engines will complement its proven line of high‑performance two‑stroke engines with ePropelled’s intelligent power systems, starter‑generators, and electronic engine starters. The resulting hybrid solutions are expected to provide:

• Significant fuel‑efficiency gains
• Extended flight duration and payload capacity
• Lower lifecycle operating costs
• Enhanced reliability and redundancy for mission‑critical applications
• Improved sustainability that meets emerging regulatory and environmental standards.

By merging mechanical power with advanced electric power generation, the new hybrid systems will serve customers who require superior power‑to‑weight ratios, long operational endurance, and dependable performance in challenging environments.

Bruno‑Gerard König, CEO of Hirth Engines, says, “This partnership elevates what our engines can achieve and opens new opportunities in fast‑growing sectors such as UAVs and advanced air mobility. ePropelled’s technology perfectly complements Hirth’s heritage of engineering excellence.”

Nick Grewal, CEO and founder of ePropelled, says, "Combining our intelligent electric power‑generation systems with Hirth’s world‑class engines allows us to deliver hybrid solutions that set a new benchmark for performance and efficiency. This collaboration accelerates the future of hybrid propulsion.”

The partnership will focus on applications including:

• UAVs and uncrewed systems
• Advanced air-mobility (AAM) platforms
• Defense and surveillance missions
• Industrial and commercial aerial applications
• Lightweight hybrid ground vehicles.

Research, development and system‑integration work have already begun. Prototype demonstrations are expected in upcoming project cycles and will be available to view at UMEX in Abu Dhabi in January 2026.
