No low range gearbox in a CRV.
5 speed and lockers rare?

I was kidding about the CRV. Those pics are still of a 4WD vehicle - there's a transfer case shifter in the last pic. Please explain to me how AWD will go places that 4WD won't. By your theory, I guess I should remove my rear locker cuz slippage is better than traction right?

Hahahahahahaha. This argument is funny! But i have to side with brian on this one.
Where is the AWD part of the Rock Crawler i cant see it. That mofo is dual locked 4wd.

AWD isn't designed with ultimate traction in mind as much as it offers control on harder slick surfaces;when any wheel slips the computer pulls the power from those wheels and diverts it to the wheels with traction. AWD really isn't good on soft surfaces either when you need constant power to all the wheels.

He is running the stock AWD drive system, if you look at the little shifter it is H-N-L.

Your partly right but AWD doesnt have a 4lo. Settles that.
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 can be used full time on all surfaces including pavement. The additional feature of a differential incorporated into the transfer case makes it possible to use 4WD all the time.
2WD is not available (only part time 4WD offers that option). Each tire creates about 25% of the available torque when the ground is level with a consistant surface. Driver has a choice of a "4-high" (that's your every day setting) and "4-low".
Full time 4WD vehicles work very well on-road and are very capable off-road.
When "4-low" is selected the wheels create substantially more torque (on a Grand Cherokee its 2.72 times more) than in "4-high" - at the same time the vehicle moves at substantially slower speeds (2.72 times slower on a Jeep Grand Cherokee).
Important: "4-low" does not create more traction - it creates more torque and that can be detrimental when traction is marginal. Slipping tires are more likely in "low" than in "high"!
The low setting is an advantage for drivers who need to tow and maneuver a heavy trailer etc. and for drivers who at one point or another may want to negotiate difficult off-road terrain, when more torque and/or slower speed is needed.
All 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. Full time symmetric AWD would be the best term to be used. Difference to full time 4WD is that a "4-low" setting is not available in AWD cars. 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.
Automatic AWD system is the newest kid on the block. PR agency generated names like "Real Time 4WD", "intelligent AWD" or "active AWD" are hiding the fact that automatic AWD is essentially a sophisticated 2WD system. Automatic asymmetric AWD would be the best term for them.
Here is how they work: Under normal conditions one axle gets 100% of the torque - meaning you are driving in 2WD. During traction loss at the driven axle (could be front or rear) a fully automatic system (hydraulic, mechanical or electronic) makes up to 50% of the torque to the axle with traction available. 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. Once the primary driven axle regains traction and both axles rotate at the same speed again, the system reverts back to 2WD. So, for a moment you had AWD.
Automatic asymmetric AWD is much less capable in off-road settings than full time AWD systems and inferior to full time 4WD. However, automatic asymmetrical AWD is becoming more and more sophisticated and offers pretty much everything consumers expect for everyday (pavement) driving.
Examples: Honda CRV, (newer) Toyota RAV4, LandRover Freelander, Isuzu Trooper (TOD), Volvo V70, 1999 and later Jeep Grand Cherokee (in high range).
Recently some magazines have called the automatic AWD system "part time 4WD", since it offers AWD only part of the time. They have a point - however, the term "part time 4WD" has been used since WW II for cars like the Willys and Jeep Wrangler and their part time 4WD . A manual system where the driver had to select 2WD or 4WD. The name coming from the fact that 4WD was designed to be used only part of the time (when off-road), most of the time it had to operated in 2WD (on-road).

It is a confusing subject especially since the technology keeps changing too, but that's what these forums are for. I think the choice to unlock the center diff and have AWD would be very cool to have. I could have used that a lot this week. There's black ice all over the place where I live right now and driving around in 4WD sucks because 80% of the road is dry. I find myself driving slow in 2WD and watching the road really carefully. If I had AWD, it would definitely be a little safer.

i hate stupid manufacturing terminology, it should be simple like stated above part time has been used since the beginning of 4x4's, *uck stupid companies trying to confuse things by calling a cow a pig.....ggggggrrrrr
there should only be three then have categories below that.
instead you get all of this "select track automatic awd 4x4" bull hockey... wtf is that? you know
full time
part time
awd
