At CES 2025, amidst the digital gadgets, two innovative engines captured everyone’s attention: a 1.5-liter Australian model and a 2.0-liter Chinese variant, proving that high-tech isn’t just for software alone.
a technology-dominated show marked by mechanical innovation
The CES 2025, traditionally a playground for the latest digital and software advancements, witnessed two standout hardware innovations in the automotive hall. A German company unveiled a four-cylinder flat turbo engine, the Sytech S415 TC, poised to become an autonomy extender in China. Nearby, another horizontal engine made waves: Great Wall Motor’s 2.0-liter eight-cylinder designed for the new SOUO S2000 motorcycle.
the s415 tc: a revolutionary design
This engine stands out thanks to its crosshead mechanism, known as “Scotch Yoke,” which transforms the pistons’ linear motion into rotation. This design significantly reduces lateral forces on the pistons, lowering wear and increasing efficiency. The result? An 8% increase in combustion time, a 26% reduction in NOx emissions, and an overall improvement in energy efficiency.
towards a range of versatile engines
The showcased Sytech S415 is part of an engine family that includes configurations with two, four, or eight cylinders, capable of being naturally aspirated with indirect injection or turbocharged with direct injection. They can run on gasoline, hydrogen, or natural gas—either liquid or gaseous—offering unprecedented flexibility in fuel choice.
performance tailored to various applications
- Hydrogen at low pressure: Power ranges from 67 hp
- Hydrogen at high pressure (turbo-injected): Up to 162 hp
- Gasoline: Power varies from 80 to 148 hp
This demonstrates the engine’s ability to adapt to diverse energy needs and environmental regulations.
a compact design for easy integration
Thanks to its compact design, the S415 can be installed in various vehicle configurations, offering increased flexibility for automakers to optimize space and enhance overall vehicle performance.
the world’s first flat-8 motorcycle with eight speeds
From Great Wall Motors comes the GW8M20 flat-8 engine designed to surpass Honda Gold Wing in every metric. With higher torque and peak power of 152 hp, this engine is ideal for touring missions, delivering superior driving experiences without sacrificing performance.
market comparison and competitiveness
Despite starting at a higher price than Honda Gold Wing, the GWM Souo offers a better power-to-weight ratio, making this motorcycle more attractive for those seeking optimal performance coupled with exceptional luxury and comfort.
This article explores how technological advancements in engine design presented at CES 2025 could transform the automotive and motorcycle industries. By combining mechanical innovations with fuel flexibility and improved environmental performance, these engines aren’t just following trends—they’re setting them.
