"Revolutionary 500cc 'One-Stroke' Engine Transforms Miata Performance"

Spanish company INNengine has developed a unique 500cc 'one-stroke' engine that defies traditional design, weighing just 85 pounds and producing 120 horsepower. The engine features opposed-pistons and lacks connecting rods, resulting in improved balance and reduced noise and vibration. It utilizes a single-stroke combustion cycle and can be used as a range extender in electric vehicles, offering a lightweight and cost-effective solution for extending their range. While it may not directly power cars, the INNengine has the potential to revolutionize the automotive industry.
