That’s because you’re thinking of trucks used first and foremost for heavy duty “truck stuff.” That is not the only market for trucks, at least in the US: https://www.thedrive.com/news/26907/you-dont-need-a-full-size-pickup-truck-you-need-a-cowboy-costume

According to Edwards’ data, 75 percent of truck owners use their truck for towing one time a year or less (meaning, never). Nearly 70 percent of truck owners go off-road one time a year or less. And a full 35 percent of truck owners use their truck for hauling—putting something in the bed, its ostensible raison d’être—once a year or less.

Low towing capacity and an outrageously miserable bed size. Less than five feet? The powertrain of this should have been put in a station wagon, not a “truck.”

It can probably tow more, usually 500 kg is like the bare minimum for American cars. Also us towing standards are a bit more strict. A car in the EU is rated to tow more than a car in the US, even if it’s identical.
