The F-150 is the half-ton version of Ford's best-selling F-Series pickup line. Like most pickups, it offers multiple configurations and powertrains. During our tests, the boxy pre-1997 F-150 rode well and quietly on most roads. Its ride and braking improved with a full load. We found the seats erect, but roomy. Ford completely redesigned the F-150 for 1998, improving comfort, handling, and refinement. An optional third door on extended-cab models became available in 1998, and a fourth door was offered in 1999. The supercharged SVT Lightning serves up sports-car-quality acceleration. A four-door crew-cab was introduced for 2001.
