It seems Ford is busy developing new vehicles these days. We’ve seen spy shots of a refreshed Explorer, a new Focus hatchback, and this, which is a long-wheelbase SUV that is much larger than the Explorer yet smaller than the Expedition. Upon closer inspection, this test mule rides on reused Lincoln Navigator wheels, has a large vertical pillar in the center of its grille, and has taillights that somewhat recall the shape of the current Navigator’s rear lights. Could it be that Lincoln is preparing a second-generation Aviator? It seems to be happening.
