So a long term test, that is divided into different parts, in this one, we learn something about fuel economy, which we could have learned from a normal test drive of 100km of mixed driving , and a bit about the payload, and the load height vs a minivan. The load height of a crossover/suv are pretty similar, as are load heights of van, and sedans. Have to say I didn't learn much. It would be nice to learn things that are unique to this experience of the Explorer.
