What is the torque multiplication factor of the Grand Cherokee?
2 Answers
When in low-range four-wheel drive, the Grand Cherokee's torque is multiplied by 2.73 times. Engine maximum torque: The engine's maximum torque is related to the design of its intake system, fuel supply system, and ignition system. At a certain RPM, when these systems achieve optimal performance matching, the maximum torque can be reached. Impact of torque on vehicles: The magnitude of a vehicle's torque plays a decisive role in its acceleration and climbing ability. Generally, the greater the torque, the better. Higher torque means the engine can deliver more "power," resulting in faster changes in crankshaft speed, which enhances the vehicle's climbing ability, starting speed, and acceleration.
The Grand Cherokee can amplify torque by approximately 2.72 times in low-range 4WD mode, primarily achieved through the Quadra-Drive II system. When you switch to this mode, the engine's output power is enhanced, making it easier to tackle steep slopes or muddy terrain. I've taken it off-roading before – when encountering large rocks, the increased power prevents wheel slippage, delivering a more stable and confident driving experience. The latest models now integrate Selec-Terrain technology, which intelligently adjusts drive modes while maintaining the same torque multiplication ratio. Coupled with electronic limited-slip differentials, its overall off-road capability is further improved. Of course, this feature isn't needed during regular driving and should only be activated in specific conditions to avoid excessive fuel consumption. Beginners should practice using it before off-roading to prevent accidental component damage. In summary, this is a hardcore design that allows the Grand Cherokee to excel in complex terrains, completely unlike the mediocre performance of ordinary SUVs.
