In production since 1948, the F-Series includes full-size pickup trucks, chassis cab trucks, and commercial vehicles. As of 2019 production, the Ford F-Series includes the F-150 pickup, Class 3-5 Super Duty trucks (F-250 through F-550), and the Class 6-8 Super Duty trucks (F-600, F-650, F-750). The most popular version of the F-Series is the F-150, now in its thirteenth generation.
The F-Series has been the best-selling pickup truck in the United States since 1977 and the best-selling vehicle since 1986; it is also the best selling vehicle in Canada. As of the 2018 model year, the F-Series generates $41 billion in annual revenue for Ford, making the brand more valuable than Coca-Cola and Nike.
In 1999, to bridge the gap between its pickup line and its medium-duty trucks, Ford introduced the F-250 and F-350 as Super Duty trucks. Considered an expansion of the F-Series, the Super Duty line is built on a distinct chassis architecture with heavier-duty components. In 2000, the Super Duty range was expanded to include Ford medium-duty trucks.
At various times, Ford has marketed the F-Series across all three of its divisions in North America. Mercury sold the F-Series as the M-Series from 1948 to 1968 in its Canadian sales network (alongside the Econoline and medium-duty trucks); during the 2000s, Lincoln sold the Blackwood and later the Mark LT.
For the 2004 model year, the F-150 was redesigned on an all-new platform. Internally, a 3-valve version of the 5.4 Liter V8 was introduced and replaced the previous 2-valve version. Externally, the eleventh-generation model was different from its predecessor, with sharper-edged styling; a major change was the adoption of the stepped driver's window from the Super Duty trucks. Regardless of cab type, all F-150s were given four doors, with the rear doors on the regular cab providing access to behind-the-seat storage. Ford also introduced additional variants of the F-150. The FX4 Off-Road package available since the 2002 model year became its own trim level. A sportier version of the F-150 became available as STX, replaced by FX2 Sport in 2007.
From 2005 to 2008, Lincoln-Mercury dealers sold this version of the F-150 as the Lincoln Mark LT, replacing the Blackwood.
In late 2007 for the 2008 model year, the Super Duty trucks were given an all-new platform. While using the same bed and cabin as before, these are distinguished from their predecessors by an all-new interior and a much larger grille and head lamps. Previously available only as a chassis-cab model, the F-450 now was available as a pickup directly from Ford.
