Before the 2021 Bronco ever reached a dealer lot, Ford built two very different visions of what a revived Bronco could be, one of them got wheeled into the design studio and rejected, the other one raced the Baja 1000 and became the production truck's blueprint.

The 2004 Concept: What Ford Almost Built
Ford debuted a Bronco concept at the 2004 North American International Auto Show, seventeen years before the production truck arrived. It looked the part on the outside: a boxy, upright roofline, round headlamps, a short wheelbase, and "BRONCO" milled directly into a three-bar grille. Exposed door hinges, cowl vents, flared wheel wells, and even an integrated winch with guide rollers in the front fascia all nodded hard at the original 1966 truck.
Under the skin, it was a completely different animal. The 2004 concept was built on a heavily modified Ford Escape platform, a unibody crossover chassis, not the body-on-frame construction the classic Bronco and the eventual production truck both use. Power came from a 2.0L Duratorq TDCi turbodiesel making a modest 128 horsepower and 244 lb-ft of torque, paired with an experimental six-speed PowerShift dual-clutch transmission and an "Intelligent" all-wheel-drive system rather than a true 4WD setup with low-range gearing. It looked like a Bronco. Mechanically, it drove closer to a car-based crossover.
Why the 2004 Concept Got Rejected
Here's the part most people don't know: Ford pulled the 2004 concept out of storage during the early design phase of the production Bronco. Paul Wraith, the head of the Bronco's design team, has said the team wheeled the old concept into the studio and lived with it for roughly six months while figuring out what the new truck needed to be.
The conclusion, in Wraith's own words, was that the 2004 concept simply "was not it." A crossover-based unibody Bronco with car-like all-wheel drive didn't match what the brand needed to deliver: genuine body-on-frame off-road capability with true 4WD low range, not just Bronco styling wrapped around a soft-roader platform. The 2004 concept's design language survived. Its entire mechanical identity did not.
The Bronco R: The Genuine Preview
The genuine blueprint for the production truck showed up in a very different way, at the 2019 Baja 1000. Ford entered a prototype called the Bronco R in the race, months ahead of the truck's planned spring 2020 reveal, and its styling was unmistakably close to what would become the final production Bronco: the same peaked front fenders, the same wheel opening shape, and "BRONCO" lettering across the grille instead of the Ford oval.
Unlike the 2004 concept, the Bronco R wasn't a styling exercise sitting on a repurposed crossover chassis. It was built and raced to validate genuine body-on-frame construction and off-road hardware under desert racing conditions before a single retail unit existed. Where the 2004 concept got shelved after six months of internal debate, the Bronco R went straight from the Baja 1000 into the production truck's DNA.
What Made It to Production
Design language carried over cleanly from both concepts: round headlights, a boxy stance, peaked fenders, and the general silhouette that ties the modern Bronco back to 1966. What didn't carry over from the 2004 concept specifically was almost everything mechanical, the unibody platform, the diesel engine, the dual-clutch transmission, and the all-wheel-drive system were all abandoned in favor of the body-on-frame, true 4WD approach the Bronco R had already proven out in the desert.
The lesson buried in this history: Ford tried the easier path first, a Bronco-styled crossover built on parts it already had, and walked away from it once the team realized styling alone wasn't enough to earn the name.

FAQ
Was the 2004 Bronco concept ever going to be built?
No. It debuted at the 2004 Detroit Auto Show as a design study and never had a production plan. Ford did briefly reconsider its design during the 2021 Bronco's early development before deciding against it.
What platform was the 2004 Bronco concept built on?
A heavily modified Ford Escape platform, a unibody crossover chassis rather than the body-on-frame construction used by both the classic Bronco and the production 2021 truck.
What was the Bronco R?
A prototype Ford entered in the 2019 Baja 1000 ahead of the production Bronco's reveal. Its styling closely previewed the production truck and it was built to validate genuine off-road hardware rather than just showcase design.
Does the production Bronco share anything mechanical with the 2004 concept?
No. The platform, engine, transmission, and drivetrain system were all different. Only the design language, round headlights, boxy proportions, peaked fenders, carried through in any meaningful sense.
