What is the difference between a 2007, 2008 and 2009 lincoln Navigator?

Hi, just wondering what the differences were in the three different models of Lincoln navigators. It may be hard to understand, but basically are there any differences in the way the 2008 model looks from the 2009 model? In other words, how do the three models look different from each other? Thanks.|||Since the 2007 model redesign the Navigator no longer uses the same 2-Speed electronic transfer case as the Expedition. While the Expedition continues to use the heavy-duty transfer case with low range 4-wheel-drive gearing, the Navigator has been demoted to a 1-Speed transfer case, lacking low range gearing and the off road torque re-calibration program that accompanied the 4L (4-wheel-drive Low range) mode.





For 2008, packaging for the Navigator's luxury and convenience features was simplified, resulting in the elimination of the perennial Luxury and Ultimate trim levels and the standardization of a number of features that were previously optional. Some of these newly standard features included heated and cooled front seats, power-folding third row seats, a power liftgate, and a 600-Watt 14-speaker THX II-Certified audio system. Also newly standard was a 3.31:1 rear axle ratio, though a 3.73:1 ratio was still available as option for the Navigator and remained standard in the Navigator L. Newly available was a rearview camera to aid in backing up.





For 2009, the Navigator's 5.4 L V8 gained 10 hp (7.5 kW) as well as flex-fuel capability. The rearview camera that was new for 2008 was now standard, as were heated second row seats, Front Park Assist, a capless fuel filler, rain-sensing windshield wipers, and Lincoln SYNC.[12]|||Good info from (i'm lying) if he is not lying about it. But to really answer your question there is no appearance difference 2007 was the first year of the new design and I believe the front lower grill was changed for 2009 but that's it.
