Four-wheelers welcomed the introduction of automatic locking hubs on the 1989 Ford F-150. Buyers had their choice of a number of powerful fuel-injected engines: a 4.9 liter straight-six, a 5.0 liter Windsor V-8, and a romping 7.3 liter International Harvester diesel that churned out 180 horsepower. The 89 Ford F150 was offered in XL, XLT, and XLT Lariat trims. Cab configurations included an extended-cab supercab, as well as a 2-door setup; short-bed and long-bed models were also available. The powerhouse pickup was perfect for farm and ranch uses, and the 4-wheel reliability delighted the off-road set. You'll still find plenty of these reliable workhorses on the road; with plenty of muscle and iron, the 1989 Ford F150 remains a favorite with tuners and project truck junkies alike. The 89 Ford F-150 isn't likely to be a hit with Al Gore, though; without some aftermarket modification, you're looking at a thirsty 18 highway/16 city miles per gallon of gas.
