The term AUV is getting less and less usefull in my opinion. About the Toyota Tamaraw, the following is written in Wikipedia:
"It is relatively affordable in the markets where sold when compared to four-wheel drive vehicles (the Kijang is a rear-wheel drive) and features high seating capacity, high ground clearance and rugged suspension, popular features in an area with generally poor road conditions and large extended families."
This describes the AUV and its intended use pretty well in my opinion. But the problem is, that the wast majority of SUVs sold today also only have rear-wheel drive, although 4WD is usually offered on them as an option.
So from the describtion in Wikipedia, the only thing separating an AUV from an SUV today is actually the price. Since high seating capacity, high ground clearance and rugged suspension is also essentially, what define an SUV.
The question then becomes, what exactly is low price? A Isuzu Crosswind Sportivo is not much cheaper than entry level versions of the old Ford Everest or the old Mitsubishi Montero Sport. And since the latter dont have 4WD either, the Isuzu is at least as capable in rural areas with poor road conditions.
The Innova on the other hand has gotten so soft, refined and expensive, thats its intended use is hardly rural areas with poor road conditions any more. Rather it appeal to families living in cities, who just want something with large seating capacity. And that is in essence the definition of an MPV.
So do we really need the AUV term any more? Or could we not just use MPV or SUV instead for these vehicles?
