Lincoln Navigator - First Drive: The big news for the 2007 Lincoln Navigator is just that: Big. The biggest Navigator yet bows with the “L” model. The styling is bigger and brasher. In terms of physical size, the Navigator L’s 14.7 inches of additional length adds 25 cubic feet more cargo carrying volume behind the third row. The bigger attitude and style are all designed to keep the Navigator in the hunt against the king of bling, Cadillac’s Escalade. Judging just by the acres of chrome the ‘Gator has the Slade nailed. But when you lift the chrome-laden hood of the Navigator its primary weakness is laid bare: A V8 that is easily overpowered by most of its competition.
