SwRI Introduces Medium-Duty Hydrogen Spark-Ignited Engine with Diesel-Like Torque

Most technical and performance claims align closely with recent Southwest Research Institute publications on its heavy-duty H2-ICE demonstrator and the new medium-duty hydrogen engine. Some statements, however, extrapolate or overstate results by implying fleet readiness, broad diesel drop-in status, and infrastructure impacts that are not yet demonstrated in real-world deployments. With minor rephrasing to clarify that several points are projections or lab/demo results, the article can be made factually robust.
