SUMMARY
The discussion centers on the comparative capabilities of high RPM gas engines versus low RPM diesel engines in moving heavy loads. A 238 HP Mack Semi, producing 1100 ft-lbs of torque at approximately 1136 RPM, can effectively pull 60,000 pounds, while a gas engine with the same horsepower but only 208 ft-lbs of torque at 6000 RPM struggles to match this performance. Key insights reveal that torque is crucial for maintaining power under load, and that gearing can influence performance, but the inherent characteristics of the engines dictate their efficiency in heavy-duty applications.
