The Machine: Our Hybrid-Electric Stemme S10e

Bridging Continents. Redefining Flight. Leaving No Footprint.

To conquer the Atlantic Ocean without relying on traditional, heavy-polluting fossil fuel systems, you cannot just build a slightly better airplane. You have to change the paradigm of flight.

Our answer to the ultimate challenge of sustainable aviation is a meticulously re-engineered, hybrid-electric Stemme S10e. By combining the aircraft’s legendary aerodynamic DNA with a custom, cutting-edge hybrid-propulsion powertrain, this unique machine is built to achieve what the industry giants still claim is decades away: clean, ultra-long-range endurance flight.

The Architecture of Efficiency: Aerodynamics Meets Next-Gen Tech

At its core, the Stemme S10e is a masterpiece of aerodynamic efficiency. With its massive wing span and unparalleled glide ratio, it is fundamentally designed to slice through the air with minimal resistance. In traditional aviation, massive amounts of energy are wasted just keeping a heavy aircraft airborne. Our platform flips the script: it utilizes the natural forces of the atmosphere, allowing the aircraft to soar efficiently over vast distances.

However, crossing the Atlantic requires more than just world-class soaring capabilities. It demands a propulsion system that is both incredibly reliable and fundamentally clean.

By replacing the conventional engine with a highly advanced hybrid-electric drive, we have created a dual-energy powerhouse. This system optimizes power delivery in real-time—utilizing electric efficiency where it counts, and smart energy management to guarantee the range required to cross the open ocean safely. It is the perfect synergy of proven aerospace engineering and tomorrow’s green technology.

The Mission Profile: The Ultimate Proving Ground

This modified Stemme is not a concept car kept under wraps in a showroom; it is an active, record-setting platform designed for the harshest environments. Every component—from the high-capacity battery management systems to the retractable propeller assembly—is being rigorously optimized and flight-tested across Europe.

In May 2027, this exact aircraft will face the ultimate test. It will fly the historic route of Charles Lindbergh, tracing a 100-year-old myth while completely rewriting the technological rules of the next century.

When Klaus Ohlmann lines up on the runway for the transatlantic crossing, this hybrid-electric Stemme will carry more than just a pilot; it will carry the definitive proof that sustainable, low-emission aviation is not a distant corporate promise for 2050. It is a reality, it is engineered by a dedicated elite team, and it is happening now.
