So it looks like the AWD and 4WD are the same SUV.
I may be showing my ignorance here, but is there a difference other than semantics? Is 4WD different from AWD, and how (assuming the vehicle only has 4 wheels)?
Within the knowledgeable, experienced "community" 4WD is recognized as being strictly a "part-time" system that must be activated via driver action with cautions as to when, or not, it is appropriate to do so.
There are literally a myriad of AWD systems in the market today, more properly called "automatic" AWD, wherein the extra drive wheels are only coupled into the engine at specific times and/or conditions.
The most desirable by a wide margin, most "safe", would be the R/AWD systems.
At the top of the F/AWD "heap" by a wide margin would be the Honda/Acura SH-AWD system. Middle ground will be the system using the above described pre-emptive systems using an electromagnetic clutch to vary the torque coupling to the rear. At the bottom will be the VC systems which will have no time to "stiffen" before TC activates.
