Why it stands out

The 2021 Ford F-350 Super Duty stands out as a heavy-duty truck that combines serious capability with a surprisingly modern feature set. In the fourth-generation Super Duty line, Ford’s use of aluminium alloy in the body made the truck more than 300 kilograms lighter on average and more fuel efficient without sacrificing towing capacity. For 2021, the F-350 could be had with the 6.2-litre “Boss” V8, the 7.3-litre “Godzilla” gas V8, or the 6.7-litre Power Stroke diesel, and the diesel remained the torque-heavy choice for buyers who needed maximum towing confidence. Ford also gave this generation a broad range of driver-assistance and towing aids, including blind-spot monitoring, forward collision avoidance, adaptive cruise control, lane departure warnings, a surround-view camera system, and Pro Trailer Backup Assist.

Practicality is another major part of the appeal. The 2021 Ford F-350 Super Duty was offered with regular cab, SuperCab, and crew cab body styles, plus six-and-three-quarter- or eight-foot beds, and it retained the wide trim spread that runs from work-focused XL models to luxury-oriented Limited versions. Inside, even basic trucks came with an 8.0-inch infotainment screen, while higher trims could be fitted with a 12.0-inch display and a configurable 12.0-inch digital instrument cluster. That said, the truck’s strengths come with familiar heavy-duty trade-offs: it is pricey, and its ride can be rough when the bed is empty. Still, for buyers who want a truck that can do hard work while offering more comfort and technology than older heavy-duty pickups, the 2021 F-350 Super Duty is a compelling choice.
