Ford has filed to trademark the name "EZ Air" in the US, as it applies to "land motor vehicle doors," and we have a suspicion that it refers to something Bronco-related.

Here's the deal: in trying to siphon away some of the Jeep Wrangler's outdoors-loving, overlanding customers, Ford planned a whole suite of hundreds of different official Ford accessories for the all-new 2021 Ford Bronco. Some of these - like a set of donut-like doors with wide open holes in their centers - were shown off in early press photos, giving us all a small glimpse of things to come.

We're going to go out on a limb and say that Ford's "EZ Air" door trademark probably refers to these open-center doors. That's significant because at the time of the Bronco's reveal, Ford said only that the doors were "among the possible factory-backed accessories" that might eventually be offered. That's the last we've officially heard on the subject.

Ford's trademark, which was filed July 8, 2020 - just days before the Bronco's official unveiling - suggests that Ford is leaning toward releasing the doors for public consumption. The doors in theory replicate much of the open-air doors-off freedom that comes with removing the doors on an off-road SUV like the Bronco or Wrangler, but with a bit more protection from hazards, the elements, and traffic accidents.

Of course, we might be off-base, and the "EZ Air" doors referred to in Ford's trademark application could be something completely different. But we rather doubt that's the case.

Aside from the open-air doors, should they materialize, the 2021 Ford Bronco will also give owners the option of easily removing the doors completely for off-road excursions, just like the Jeep Wrangler. Ford one-upped Jeep on its design, however, mounting the side mirrors to the Bronco's A-pillars so that they stay with the SUV even when the doors are off.
