Media Releases

Freedom Motors (FM) is excited to announce the breakthrough development of its 6-Stroke Rotapower® engine that was achieved by compounding its successful 4-stroke version. Compounding involves using exhaust energy to supercharge the intake charge while concurrently extracting mechanical energy directly from the exhaust through a fifth stroke (second expansion stroke). Further research showed that adding a second intake stroke to supercharge the Rotapower engine could substantially increase its power output and thermal efficiency. This was accomplished by using the intake and compression stroke of the second rotor to supercharge the first power rotor and thereby create a six stroke Rotapower® engine. This additional supercharging stroke provided the following benefits:

• Volumetric efficiency substantially improved.
    This is a major contributor to its power increase of over 60%
• Stratified charge made possible.
    Improves thermal efficiency during partial throttle operations.
• Torque curve can be tailored to the application.
    Can operate on the Diesel cycle.

These benefits are in addition to the five stroke Rotapower® engine version benefits, which are

• Low Noise.
    The very extended expansion cycle reduces the exhausting gases to near atmospheric pressure eliminating 94% of the noise prior to muffling the remainder.
• Lower Exhaust Temperature.
    Reduced from 1,600°F to less than 1,000°F.
• Fuel consumption reduce.
    Up to 25% once the port timing and sizes are optimized through the use of gas dynamic modeling, computer aided design and dynamometer testing.

Rotapower® six stroke engine will revolutionize the industries such as VTOL aircraft, Range extenders for EVs, Generators, Biogas-to-power generation, 2 and 3-wheelers, and many more.

Jackson, Wisconsin – December 14, 2024 – Freedom Motors, a leader in adaptive mobility and cutting-edge engine technology, is pleased to announce that Ron Spoerl, President and CEO of Aambe Corporation, has joined the company as a strategic partner and advisor. With his extensive leadership experience and strong ties to Native American Tribal Nations, Spoerl’s collaboration with Freedom Motors will enhance the company’s ability to deliver innovative, cost-effective, and environmentally friendly solutions to diverse communities across the nation. Spoerl brings over two decades of experience in Tribal economic development, entrepreneurship, and business strategy, all of which will support Freedom Motors' growth. As a federally recognized Tribal member of the Little River Band of Ottawa Indians, he has a proven track record of leveraging his unique understanding of Native American communities and business needs. Through his leadership at Aambe Corporation and its division, NativeFirst Capital, Spoerl has empowered businesses within Indian Country, and his strategic guidance will now help Freedom Motors expand its impact in underserved communities, including Native American nations.

Revolutionary Engine Technology for a Sustainable Future

At the core of Freedom Motors’ vision is the groundbreaking Rotapower® engine, a unique and patented technology that combines the best features of rotary and piston engines. The Rotapower engine’s proven, inexpensive technology was originally developed by Outboard Marine Corporation (OMC), which invested $250 million in perfecting its rotary engine design. OMC produced over 35,000 rotary engines for snowmobiles, accumulating over 5 million operational hours, and demonstrated the rotary engine’s ability to compete cost-effectively with two-stroke piston engines. Freedom Motors has since acquired OMC’s core rotary engine technology, enhancing it with proprietary advancements to improve reliability, fuel efficiency, and dramatically lower emissions. The company’s new design, featuring patent-pending intake porting and rotor interface, has optimized the engine’s performance, achieving a leading power-to-weight ratio of 3:1. These advancements reduce fuel consumption and emissions by more than 85% compared to traditional industrial four-stroke piston engines and recreational two-stroke engines, making the Rotapower® engine one of the most environmentally friendly and cost-effective solutions on the market.

NASA-Backed Innovation

The development of Freedom Motors’ Rotapower engine has been further supported by cutting-edge research, including collaboration with NASA. Through NASA’s Small Business Innovation Research (SBIR) program, the company received funding to incorporate advanced coatings into the engine. These coatings, developed with NASA’s Glenn Research Center, significantly improve fuel efficiency, reduce emissions, and extend engine life by minimizing wear and friction. This technology has been praised for its ability to make engines cleaner, more efficient, and capable of running smoothly on a variety of fuels.

The Future of Mobility and Accessibility

By joining Freedom Motors, Ron Spoerl is combining his deep knowledge of Tribal business needs with the company’s commitment to innovative, accessible, and environmentally responsible technologies. Spoerl’s expertise will help Freedom Motors expand its reach, particularly within underserved communities, while delivering reliable mobility solutions that promote independence. “Freedom Motors represents an exciting opportunity to contribute to the economic empowerment of Native American communities while supporting a sustainable future,” said Ron Spoerl. “The Rotapower® engine is not only a breakthrough in efficiency and cost-effectiveness, but it also aligns with my commitment to developing environmentally responsible solutions that meet the needs of diverse communities.”

About Ron Spoerl and Aambe Corporation

Ron Spoerl is the President and CEO of Aambe Corporation, a company dedicated to economic development and capital access for Native American businesses. With deep roots in Tribal economic development, Spoerl has successfully leveraged his leadership to support Indigenous entrepreneurship through NativeFirst Capital, which provides critical capital and business solutions for Native American communities.”

Freedom Motors has leased 8,000 sq. ft. of manufacturing space that will be used initially to begin fulfilling its contract with OneH2. Over the last year our Chief Engineer has been leading a group at the OneH2 facility in North Carolina where they are testing our engine powering a genset on hydrogen. These gensets are to be installed in forklifts to be used by Amazon. FM now has firm orders, conditional orders, and letters of intent for over 3.5 million engines. The firm contract with OneH2 is for 26,200 engines. A large portion of the conditional orders are for two and three wheel motorcycle/motor scooters in Asia. It is difficult to competitively produce engines in the US for foreign orders, and therefore, we have an agreement in process to produce engines under license in Singapore for the ASEAN market (20 different countries).
