Fuel mpg: daily - 24-27; short trips (100-200 mi.) - 26-28; winter daily - 21-26 (lot of idling); and, long trips - 5000 mi in Mar. 08 was 27-32 depending on the leg. On the open country interstates the mpg eould start to drop if I exceeded 69 mph see full Ford Five Hundred review

Trip to Florida from WV 29.4 mpg. On the way back, 28.7mpg. I avg. about 24.5mpg back and forth to work, some in town driving (15%) mostly rural (85%). For an AWD and the size, this is fantastic. see full Ford Five Hundred review

The V-8 is thirsty for city driving. The extra power would be nice for highway & mountain driving, though. see full Mercury Grand Marquis review
