So, for a brief moment you had AWD.ДЄutomatic AWD is much less capable in off-road settings than full time AWD systems and inferior to full time 4WD. Once the primary driven axle regains traction and both axles rotate at the same speed again, the system reverts back to 2WD. This means you have to lose traction in 2WD on your driven axle first and then the other axle will be added and try to keep the car moving and stable. During traction loss at the driven axle (could be front or rear) a fully automatic system (hydraulic, mechanical or electronic) makes some of the torque to the axle with traction available. Here is how they work: Under normal conditions one axle gets 100% of the torque - meaning you are driving in 2WD. Since it is based on an existing 2WD steup, it is also referred to as a 'hang on' solution. Engineers refer to this system as an 'on demand system'. Since AWD is only engaged on rare occasions, sometimes automatic AWD is falsely called 'part time 4WD'. Only on rare occasions all 4 wheels will be powered very briefly.

Automatic AWD is NOT powering all 4 wheels all the time.

Time 4WD', 'intelligent AWD' or 'active AWD' are hiding the fact thatДЄutomatic AWD is essentially a sophisticated 2WD system. Due to the lack of 'low range', AWD vehicles are much less capable in off-road settings than full time 4WD vehicles, but work perfectly well on-road. Difference to full time 4WD is that a '4-low' setting is not available in AWD cars. It can be used full time on all surfaces including pavement like full time 4WD.

and for drivers who at one point orДЄnother may want to negotiate difficult off-road terrain, when moreДЄll wheel drive (AWD) is almost the same thing as full time 4WD - it is a system that powers all four wheels of a vehicle at all times as well. The low setting is an advantage for drivers who need to tow and Slipping tires are more likely in 'low' than in 'high'! On snowy, icy roads 'low' would be a bad choice - some really deep snow, however, puts up so much resistance that 'low' is needed to push forward. Important: '4-low' does not create more traction - it creates more torque at slower speeds and that can be detrimental when the ground is slippery. Same time the vehicle moves at substantially slower speeds (2.72 times (on a Grand Cherokee its 2.72 times more) than in '4-high' - at the When '4-low' is selected the wheels create substantially more torque

Driver has a choice of a '4-high' - 4H (that's your every day setting) and '4-low' - 4L.ДЇull time 4WD vehicles work very well on-road and are very capable off-road. Each tire creates about 25% of the available torque when the ground is level with a uniform surface. The additional feature of a differential incorporated into the transfer case makes it possible to use 4WD all the time.ДўWD is not available (only part time 4WD offers that option). Full time 4WD, also called permanent 4WD, (not to be confused with: part time 4WD ) is a system that powers all four wheels at all times and it can be used full time on all surfaces including pavement.
