Wouldn’t a people carrier have been adequate? I don’t think people have an issue with the desire for interior space for families, it’s more an issue with the unnecessary extra size and weight brought on by the offroadesque styling
If so, many minivans are ~similar in size, weight, and capacity to modern SUVs (not all SUVs are a Chevy Suburban :-)). For example, you can compare the Honda Odyssey to the Mazda CX9 and the specs are actually not too different:
Mazda CX9: weight: 4,409lbs, 199″ L x 78″ W x 68″ H
Honda Odyssey: 4,482lbs, 205″ L x 79″ W x 70″ H
Edit: formatting
An MPV such as the ford cmax will have as much practicality than a much bigger SUV
Also, wheel base and weight are not the best way to compare overall utility of a vehicle.
