Car and Driver put together a new article that goes through all the information that's out so far about the Bronco. In the article they also created these renderings for what a 4-door version could look like.
It Will Look Like a Bronco
While it is based on Ranger/Everest underpinnings, its look will be a clean-sheet design with careful consideration (read: pandering) paid to all the things that make a Bronco a Bronco. It's no coincidence that Ford's carefully crafted modern-era Bronco will be similar in scope to the Jeep Wrangler, which has gained popularity in the years since the Bronco began its hibernation in 1996. Despite a few upstarts that briefly made waves, including the Nissan Xterra and the Toyota FJ Cruiser, Jeep has owned this off-road-SUV space for more than two decades. Remarkably, for two years now, FCA has sold more Wranglers than Nissan sold Altimas or Ford did Fusions. The Bronco, which will debut this spring as a 2021 model, will certainly look to make a dent in those numbers, although it isn't likely to be a volume seller like the Escape, the Explorer, or even the upcoming Escape-based Bronco Sport crossover.
Huge sales numbers are not the reason you roll out a niche model like this. The Bronco is mostly meant to get people excited about Ford SUVs again, so the styling will have to make an impact. As previewed by the Bronco R off-road race prototype, a squared-off hood and imposing Raptor-style grille that says "Bronco" in giant block letters will leave no doubt as to the identity and attitude of this model. We anticipate it'll have round headlights, lending a retro touch, and 35-inch all-terrain tires with plenty of wheel clearance for off-road capability. A chunky full-size spare tire will likely hang off the back.
Doors and Roof Come Off
As previously mentioned, both two- and four-door versions will have doors that can be taken off for open-air fun, complementing a removable hardtop. The Bronco's side mirrors will be mounted on the A-pillars, and the doors will be stowable in the cargo area. Patents for the door-removal system show a set of latches, a far simpler solution than the hinges on the Wrangler's doors, which require tools to take off. Expect extradurable interior parts that will stand up to the elements, as one engineer let slip to us that waterproofing sensitive components, such as the power seats, was a challenge.
In a departure from Jeep's approach, Ford is envisioning the Bronco as more of a high-speed desert runner than a low-speed rock crawler (though the Bronco R race truck failed to finish the Baja 1000 this past November). This means the Bronco won't adopt an old-school live axle up front like the Wrangler and will instead have a long-travel independent suspension. The rear will be a live-axle setup with leaf springs, and both axle designs will be supplied by Dana. We expect the most hardcore Bronco will offer electronic anti-roll-bar disconnects and borrow the locking rear differential from the Ranger Raptor (not sold in the U.S.) and possibly the Torsen limited-slip front diff from the F-150 Raptor.
