Lugging is defined as which operating condition?

Explanation:
Lugging happens when the engine is in too high a gear for its current speed, so the RPM is too low for the load. In that situation the engine can’t develop enough torque to keep and build speed, so it strains, runs roughly, and fuel efficiency drops. The fix is to downshift or increase the RPM so the engine operates in its effective torque range, which relieves the strain and restores smooth power. This isn’t about low RPM in neutral (there’s no load there) or about high RPM in high gear (that would be over-rev/underperformance isn’t the issue), and while heavy load can contribute, the defining feature of lugging is too-low RPM in a high gear.
