Apparently someone found a good thing and decided to stick with it. It’s not quite a trifecta of Escapes as the one on the right is the Mercury Mariner sister model but all three hail from the 2008-2012 update era of the original Escape model. Obviously variety is the spice of life for this owner, it’d be boring if they were all exactly the same.
In fact, the Mariner is actually a Hybrid version. Ford was the first to stick a Hybrid powertrain in a CUV (2005 Escape, 2006 Mariner) and it seems to have paid off, these were extremely popular, the biggest curiosity is why they abandoned the idea for the next generation entirely only to return to it in the current one. Many of the Hybrids ended up in the taxicab market, either from new or purchased used. There isn’t much greater recognition of a vehicle being pretty robust and inexpensive to operate than seeing many of them in such as fleet.
The Escape at the top of the driveway is actually a Hybrid as well, with the now apparently not actually silver but a grayish color instead one behind it being an example of the V6 powered Escapes. Sticking a V6 into a compact CUV was also a somewhat novel concept when Ford did it upon the original Escape’s introduction for 2001. In any case, they seem to work for this owner, perhaps one day he or she will make the leap to adding a “foreign” vehicle to the fleet and pick up a Mazda Tribute.
