Everest? Expedition Max? We've heard it called several things, but here is the first picture of Ford's extended Expedition.

Longer? You bet. The stretched Expedition is potentially as much as 16 inches longer than the standard model.

The Expedition will be redone for the 2007 model year, and it will once again be riding on a modified F-150 platform. In addition to the standard model, there will be this Suburban/Yukon XL-sized Expedition.

This test vehicle is likely powered by a V-6 diesel, but an optional 6.2-liter V-8 - referred to as the Hurricane - may follow for the 2008 or 2009 model year.

So basically instead of a Super Duty based Excursion, there will be a long-wheelbase version of the Expedition. I guess it's slightly less of a road mastadon?
