Like most other large SUVs, the 2012 Lincoln Navigator has disappointing fuel economy.
As one of the heaviest, largest sport-utes on the market, the Navigator's low gas mileage numbers aren't too surprising. The EPA rates it at 14/20 mpg in rear-wheel-drive form, and at 13/18 mpg when four-wheel drive is specified.
Think of it from another point of view, though, and the Navigator nets out better. The biggest Lincoln seats up to eight passengers, which makes it superior on a per-person average than many mid-size, luxury crossovers that get higher numbers in the EPA cycle.All 2012 Navigator models are E85-compatible, but with that fuel its ratings drop to 9/13 mpg (4WD).
