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 for this 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 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.

There's a lot of smack talk about Detroit automakers these days, and while some of it is spot on, other myths are no more credible than what's written in the men's john. General Motors is apparently tired of fielding questions surrounding this bathroom fodder and the embattled automaker is busting out its own Sharpie to dispel what it feels are untruths. GM has created a Web 1.0 site called GM Facts and Fiction on which are several statements often said in the media and around the water cooler that its feels are untrue. For example, much talk has come up concerning government bailouts, and GM Facts and Fiction counters that the federal money would not be a bailout but rather low-interest loans earmarked for developing fuel-efficient vehicles. Other topics of purported myth include fuel economy, product desirability and the Chevy Volt. Hit the link below to see GM's latest five fact-and-fiction posts, and let us know if you think the automaker is on the mark or just scribbling lavatory graffiti of its own.
