GMC cars with highest engine torque

Torque is engine rotation force. The higher the torque, the more power engine makes at any given rotations per minute (RPM).

Torque is proportional to force pistons generate during the power stroke. This force depends on cylinder size and fuel mixture density - bigger cylinders or higher boost pressure will yield more torque.

Therefore this list is dominated by very large engines or engines with turbochargers or superchargers.

Electric motors in electric supercars also generate high torque output and maintain it throughout the RPM range.
