Dear All,
4 Wheel drive as the name explains is transfer of power to all the four wheels of an automobile. This is done for 2 purposes.
1. Additional traction for road-cars (All Wheel Drive) e.g - Audi Quattro
2. Off the road driving - In this feature, the SUVs have a selectable hi- low range in the transfercase which increases the torque at lower rpms so that these vehicles can climb or negotiate tough terrain at lower speeds.
Please let me know if you want any further information.
May the FOURs be with you - JEEP
