Ford sold 131k Mavericks in '24 vs 46k Rangers. The Ranger Raptors sat almost endlessly on dealer lots. American buyers don't want to pay up for a midsize truck. For that segment they want cheap and fuel efficient. Maybe the Ranger HD will have decent efficiency, but how is it priced?
Edit: appears to be $75-90k AUD which is $45-55k USD. I don't understand what market segment that would appeal to here. I don't think there's a lot of overlap between people who want that payload capacity and people who want a small truck. Americans looking for a small truck want to be able to haul flats of flowers, some 2x4s, their kids stuff from their dorm, etc.
