The 2007 Navigator was unveiled at the Chicago Auto Show in February 2006. It is joined by a long wheelbase Navigator L based on the Expedition EL and shares the new Ford T1 platform with that vehicle. The L model is 14.7 in (373 mm) longer than the standard Navigator.

The new Navigator sports a large chromed grille and "power dome" hood to emphasize its size and power. An independent suspension debuted in the second generation Navigator. However, the 2007 model has a greatly improved design that will cause the new Navigator to ride even better than the vehicle it replaces. The 5.4 L 24-valve InTech engine remains unchanged, however, and is now surpassed in size by the 6.2 L unit in the competing Cadillac Escalade, but with the new "power dome" and the upcoming 6.2 L Ford Hurricane engine the displacement and power will be almost equal.

Although most other Lincolns will adopt a three-letter name for 2007, the Navigator name will remain unchanged.
