* 4x4 (AWD): All-Wheel Drive. This is a more sophisticated system designed for improved traction in various conditions, primarily focusing on on-road handling and stability. Power is distributed to all four wheels, usually with a bias towards the rear wheels in normal driving. It automatically adjusts power distribution based on wheel slip and other factors sensed by the system. It's generally better for snow and slippery conditions, but not intended for serious off-road use. Think of it as enhancing everyday driving safety and control.
* 4x4 (4-Lock): Four-Wheel Drive with Low Range. This is a more robust, off-road-capable system. In addition to distributing power to all four wheels, it features a low-range gear setting. Low range drastically reduces speed but significantly increases torque, making it ideal for tackling challenging terrain like mud, rocks, and steep inclines. It often (but not always) has a selectable 4WD mode so you can engage 4WD when needed instead of it being always active like AWD.
In short:
* AWD (All-Wheel Drive): Primarily for on-road traction and improved stability. Better for snowy or icy roads, but less capable off-road.
* 4-Lock (4WD with Low Range): For both on and off-road use. Designed for significantly more challenging terrains due to the low-range gearing.
Choosing between them depends on your driving needs. If you mostly drive on paved roads but want added security in winter weather, AWD is likely sufficient. If you frequently venture off-road or need maximum traction in extreme conditions, the 4-Lock system is the better choice.
