The window sticker on a 2008 Navigator shows a mighty low 12 mpg in the city, and only 18 on the highway, so Ford went back to the drawing board to improve on that number next year. The Blue Oval’s blinged-up luxury sled boasts a fuel friendlier average of 14/20 for 2009, a marginal improvement, but an improvement nonetheless. Ford says those numbers are good enough to put the Blue Oval at the head of the luxury SUV space that includes the Cadillac Escalade, Lexus LX570, and the Nissan QX56. Ford was able to increase fuel economy by almost 15% on the big SUV by implementing some of the same engineering tricks employed on the 2009 F-150, which itself gets up to 15/21 in SFE trim. Changes were made to the idle speed and the transmission, as well as some fancy software engineering that regulates gas consumption by using aggressive deceleration fuel shut-off.

Ford also made standard several items that were previously only available as options, including a Power lift gate, heated and cooled front seats, PowerFold third-row seats, cap-less fuel filler, Rear View Camera, flexible fuel-capable V-8 engine, SYNC and the stunning 14-speaker THX II-Certified audio system. The 2009 Navigator will also be available with Ford’s new and improved navigation system with Travel Link. Ford hasn’t announced any improvements for the Expedition, but we’d expect Ford’s blue collar version of the Navigator will receive similar fuel economy enhancements.
NAVIGATOR DELIVERS CLASS-LEADING FUEL ECONOMY
DEARBORN, Mich., Sept. 24, 2008 – The 2009 Lincoln Navigator offers more than impressive levels of luxury and functionality – it also boasts a significant improvement in fuel economy that puts it ahead of the other full-size luxury sport utility vehicles in the segment.
The Navigator, thanks to a combination of architectural changes and systems engineering enhancements, has increased its fuel efficiency to an EPA-estimated 14 mpg city and 20 mpg highway on 4X2 models.
Combined with overall setup changes that offer lower idling speeds and transmission enhancements, the additional fuel economy makes the Navigator an even more appealing choice in the full-size luxury-utility segment.
“You’ll notice the difference,” said John Rich, powertrain integration and program manager for Ford Trucks. “We’ve improved the attributes and performance significantly.”
