Sixty years separate the 1966 Ford Bronco from the one in your driveway, and the numbers between them show exactly how far the truck has come. This isn't the full generation-by-generation history, that's covered in our complete Bronco history guide, this is a direct look at how the original stacks up against today's truck on size, power, price, and technology.

Size and Body Styles
The 1966 Bronco rode on a 92-inch wheelbase, a genuinely compact footprint by any era's standard, and it came in exactly one body configuration: 2-door. Ford offered it as a doorless Roadster, a half-cab Sport, and a fully enclosed Wagon, but every one of them was built on that same short, narrow chassis.
Today's Bronco spans two wheelbases, 100.4 inches for the 2-door and 116.1 inches for the 4-door, a length the original lineup never offered in any form. The modern Bronco's 4-door alone stretches to roughly 189 inches overall, nearly three feet longer than the 1966 original. The compact, tossable proportions that defined the first Bronco are gone from the current lineup entirely, replaced by a truck built around cabin space and cargo capacity the original was never designed to carry.
Engines and Power
The 1966 Bronco launched with a 170-cubic-inch inline-six making 105 horsepower and 158 lb-ft of torque, mated to a three-speed manual and nothing else. A 289-cubic-inch V8 arrived partway through the model year as an option, bumping output to 200 horsepower, a genuine jump but still modest against what followed decades later.
The current Bronco's base 2.3L EcoBoost four-cylinder alone outproduces that original V8, and the lineup tops out with the Raptor's twin-turbo 3.0L V6 at 418 horsepower, more than four times the original six-cylinder's output from a smaller-displacement engine. None of the classic Bronco's engines, six-cylinder or V8, would keep pace with even the base engine in today's lineup.
Price Then and Now
The 1966 Bronco carried a base price around $2,194. Adjusted for inflation, that lands somewhere in the neighborhood of $21,000 to $22,000 in today's dollars, a rough conversion since exact inflation math varies by method, but a useful ballpark.
The 2021 Bronco relaunched at $28,500 for the base 2-door, before destination charges. That's meaningfully more than the inflation-adjusted 1966 price, though the two trucks aren't really comparable on value alone: the modern base model ships with standard 4WD, a touchscreen infotainment system, multiple GOAT Modes, and safety equipment that didn't exist as a category in 1966, let alone as standard content on an entry-level off-roader.
Transmission and 4WD
The original Bronco offered exactly one transmission at launch, a column-shifted three-speed manual, paired with a two-speed transfer case that allowed shift-on-the-fly between two and four-wheel drive, a genuinely modern touch for 1966 even if the rest of the drivetrain was simple by necessity.
The current Bronco offers a 7-speed manual with a dedicated crawler gear on lower trims or a 10-speed automatic across the lineup, backed by an electronic transfer case and, depending on trim, front and rear locking differentials the 1966 truck had no equivalent for at all. Locking diffs weren't a Bronco option in any form until decades later in the classic run.
Off-Road Technology
The 1966 Bronco's off-road capability came entirely from mechanical simplicity and low weight, there was no electronic terrain management of any kind because the technology to build one didn't exist yet. Drivers read the terrain themselves and made every call on wheel placement and throttle input without any system helping in the background.
Today's Bronco runs GOAT Modes that adjust throttle mapping, traction control, and locking differential behavior for the terrain selected, along with Trail Control for low-speed crawling and, on select trims, a front sway bar disconnect for added articulation at the push of a button. The original Bronco's off-road reputation was earned through simple, rugged engineering. The modern truck earns a similar reputation through a mix of mechanical capability and software most 1966 engineers couldn't have imagined building into a production vehicle.
What Carried Over
Design language is the clearest link between the two trucks: round headlights, a boxy stance, and a general silhouette that today's Bronco deliberately references rather than coincidentally shares. The GOAT name itself traces back to a 1963 internal Ford memo, repurposed decades later into the modern terrain dial rather than invented fresh for the relaunch.
Almost everything else, size, power, price, and the underlying technology, changed completely across the 55-year gap between the two trucks. For the full generation-by-generation story of how the Bronco got from one to the other, read our complete Ford Bronco history guide.
FAQ
Did the original Ford Bronco ever come as a 4-door?
No. Every Bronco from 1966 through 1996 was a 2-door vehicle only. The 4-door configuration didn't exist until the sixth generation launched in 2021.
How much horsepower did the original 1966 Bronco have?
105 horsepower from the standard 170-cubic-inch inline-six. The optional 289-cubic-inch V8, added partway through the 1966 model year, made 200 horsepower.
What did the original Ford Bronco cost when new?
Around $2,194 for the base model in 1966, roughly $21,000 to $22,000 in today's dollars adjusted for inflation.
Does the modern Bronco share any parts with the original?
No. The two trucks don't share a platform, chassis, or drivetrain component of any kind. The connection is design language and naming, not shared hardware.
