The Ford F-150 is new from the ground up for 2015. Starting from its redesigned steel ladder-frame chassis, every aspect of the truck is new, including a shift to aluminium body construction and a general push towards "EcoBoost" turbocharged engines. In 2018, it got a facelift, engine upgrades and new transmission. Available in single cab, "SuperCab" quad-cab and "SuperCrew" double-cab body styles, engines on offer in the 2019 Ford F-150 include a 3.5-litre turbo V6 and a 5.0-litre V8, both with 10-speed automatics and power upgrades. Further configurations include a choice of rear-wheel-drive or four-wheel-drive with low-range, while an "FX4" package can add offroad suspension, rear locking diff and skidplates to any model except the base one. Aside from the usual basic features such as power windows, keyless entry and electric mirrors, other features, depending on trim level, include remote tailgate locking and release, unique "BoxLink" tailgate attachment points that accept standard attachments used in moving trucks and trailers, stowable loading ramps that attach to the BoxLink points, optional LED headlights, optional all-around LED lighting including side-mirror "flashlights" and in-bed lighting, 170-degree opening half-doors on SuperCab models, flat rear load floor in SuperCab and SuperCrew cabins, 360-degree camera view, adaptive cruise control, lane-keeping assist, blind-spot warning and even a panoramic sunroof. And it still has that built-in step in its tailgate to climb onto the bed, aside from new pop-out steps on the sides of the bed. Standard safety features in the 2019 Ford F-150 include ABS, ESP, front and side-airbags, and optional rear inflatable belts.
