...I did drive a AWD gmc safari for a time and I gotta say I was rather impressed...
True AWD is not the same as AWD
Assist. The transfer case or transmission of true AWD vehicles is evenly distributing power to both axles at all times. There ain't nothin' new or innovative about (true) AWD... 50 years ago it was called "Full-Time 4WD". A transfer case that could be shifted in and out of 4WD via user input (i.e., a shift lever or even a bush button) was called "On-Demand 4WD".
In 1990 Ford put an Electronic AWD
system in their rear drive Aerostar mini-van; when the
system detected rear wheel spin it automatically engaged the front axle... this was essentially a rear wheel drive with
front assist. The
system used a unique center differential transfer case controlled by electronics... meaning the system regulated power between the axles, power was not necessarily distributed equally to the front and rear. The system made it possible for soccer mom to drive up the inclined driveway in a snow storm... it was never intended to be 4WD. When cruising down an icy roadway it was still a rear drive vehicle, the fronts were not pulling... you could "lose" the front end on ice and snow just as easily as you would with the rear wheel drive only.
The original SUVs were either "Full-Time 4WD" or rear drive with (manually engaged) "On-Demand 4WD" and designed with off-road capability... such as the Bronco, Blazer, Suburban and the like. The next generation of SUVs, such as the Explorer, S-10 Blazer, and such, were still designed with at least some limited off-road capability in mind. But what we have now is not intended for any sort of off-road use... they are
front wheel drive vehicles with rear assist. They may be marketed as AWD, or even as "Electronically Controlled On-Demand AWD"... but they ain't really "On-Demand" 'cause the user cannot "demand" engagement, and they ain't 4WD either. Heck, most of 'em ain't really even a SUV, they're actually a CUV (Crossover Utility Vehicle)... the Tahoe and Expedition are SUVs. The CUV is not 4WD, they are not designed or intended for any sort of off-road use... they are designed for soccer mom to drive up the inclined driveway in a snow storm.
