Ford’s F-series was introduced in 1948, with the various classifications being based on vehicle weight ratings. The F-150, F-250, and F-350 are all full-size pickup trucks. The F-150 is the most popular version, owing to is usefulness as both a passenger vehicle and a work truck.
The current generation of the F-150 (2009-present) is available in nine different trim levels. Cab sizes include RegularCab, SuperCab, and SuperCrew, and bed sizes include 5½’, 6½’, and 8’ lengths.
Four-wheel drive is standard in the FX4 version of the F-150, although many other versions of the F-150 are available with either rear-wheel or four-wheel drive.
