The first F-Series, called the F-1 (half ton), F-2 (three-quarter ton), or F-3 (Heavy Duty), were introduced as 1948 models. A few "modern" improvements over Ford's previous pickups were smoother body contours, integrated headlights, a bigger cab and a one-piece windshield. Two engines were available: a 226-cubic-inch inline six rated at 95 horsepower and a 239-c.i. V8 that put out 100 horses.
1951 brought a new base engine, a 215-c.i. inline six with 101 horsepower.
The F-Series continued through 1952 with some cosmetic revisions (such as different grille inserts) as well as mechanical upgrades (such as a waterproof ignition) to improve performance and durability.
A somewhat sleeker look appeared for 1953, with the hood flowing into the grille and front fenders, as opposed to sitting on top of them. The consumer-oriented pickups were now called the F-100 and F-250. Heavy-duty versions were renamed F-350.
For 1954 the "Mileage Maker" inline six grew to 223 c.i. and put out 115 horsepower. The 239 "Power King" V8 kicked out 130 ponies. A "Driverized Cab" option provided such luxuries as armrests, a dome light, a cigar lighter and sun visors. Minor cosmetic updates, mainly in the grille area, continued through 1956. Horsepower also increased, with the six rated at 137 horsepower and the V8 (increased in size to 272 c.i.) pumping out 173 horsepower.
A modern restyle occurred for 1957 with a lower hood that was now flush with the front fenders. Two body styles were available, the traditional Flareside with its separate rear fenders and a new Styleside model with smooth sides that lended a more unified appearance.
A new grille debuted for 1958.
1959 saw a larger V8 (292 c.i., 186 horsepower), the availability of four-wheel drive and two-tone interior trim along with the traditional front-end freshening. The clean '59 grille gave way to a heavy, bug-eyed scheme for 1960.
