Ford sold 522,087 F-series trucks in the USA from January to July 2018. If that figure doesn’t stun you, consider that full-line sales of Subaru and Volkswagen were just 382,286 and 365,799 in the same period. Hyundai-Kia’s full line sales were 733,474 — less than Ford F-series plus Ram pickup/chassis cab sales.
Then there are different cab sizes. Automakers usually sell big and small variants of the same basic design under different labels, but with trucks, they’re just options — regular cab, club cab, quad cab, Megacab (a Ram label). There are also different bed sizes, different lifts, and off-road variants. But they’re all reported on the same line.
There are historical and present reasons for doing that. The historical reason is likely that pickups used to have remarkably low sales, so there wasn’t much desire to list them all separately. The present reason is to have a good placement in the sales wars, especially for Ford, which can always have the best selling “vehicle” in America; but GM and FCA can claim #2 and #3, which would disappear if they started breaking up the sales lines. There are also competitive reasons for not disclosing which versions are selling better, in the hotly contested segment.
In any case, just remember, comparing pickup to car or SUV sales is a bit tough, because there are massive numbers of truck variants, and usually cars and SUVs get different names even for very closely related vehicles.
