Tuesday 10th August 1965
The Ford Bronco, intended to compete against Jeep’s CJ-5 and International Harvester’s Scout, was introduced, feeding the burgeoning four-wheel-drive market. The first Broncos were very simple, without options such as power steering or automatic transmission. The idea behind the Bronco began with Ford product manager Donald N. Frey, who also conceived the Ford Mustang; and similarly, Lee Iacocca pushed the idea through into production. In many ways, the Bronco was a more original concept than the Mustang; whereas the Mustang was based upon the Ford Falcon, the Bronco had a frame, suspension, and a body that were not shared with any other vehicle.The Bronco was designed under engineer Paul G. Axelrad. Although the axles and brakes were used from the Ford F-100 four wheel drive pickup truck, the front axle was located by radius arms (from the frame near the rear of the transmission forward to the axle) and a lateral track bar, allowing the use of coil springs that gave the Bronco a 34-foot (10.4 m) turning circle, long wheel travel, and an anti-dive geometry which was useful for snowplowing. The rear suspension was more conventional, with leaf springs in a typical Hotchkiss design. A shift-on the-fly Dana Holding Corporation transfer case and locking hubs were standard, and heavy-duty suspension was an option.
The initial engine was the Ford 170 cu in (2.8 L) straight-6, modified with solid valve lifters, a 6-US-quart (6 l) oil pan, heavy-duty fuel pump, oil-bath air cleaner, and a carburetor with a float bowl compensated against tilting. Styling was subordinated to simplicity and economy, so all glass was flat, bumpers were straight C-sections, the frame was a simple box-section ladder, and the basic left and right door skins were identical except for mounting holes. The early Broncos were offered in wagon, halfcab, and a less popular roadster configuration. The roadster version was dropped and the sport package, which later became a model line, was added. The base price was US$2,194, but the long option list included front bucket seats, a rear bench seat, a tachometer, and a CB radio, as well as functional items such as a tow bar, an auxiliary gas tank, a power take-off, a snowplow, a winch, and a posthole digger. Aftermarket accessories included campers, overdrive units, and the usual array of wheels, tires, chassis, and engine parts for increased performance. The Bronco sold well in its first year (23,776 units produced) and then remained in second place after the CJ-5 until the advent of the full-sized Chevrolet Blazer in 1969. Lacking a dedicated small SUV platform, the Blazer was based on their existing full size pickup which was a larger and more powerful vehicle, offering greater luxury, comfort and space. The longer option list included an automatic transmission and power steering, and thus had broader appeal. Ford countered by enlarging the optional V8 engine from 289 cu in (4.7 L) and 200 hp (150 kW) to 302 cu in (4.9 L) and 205 hp (153 kW), but this still could not match the Blazer’s optional 350 cu in (5.7 L) and 255 hp (190 kW) (horsepower numbers are before horsepower ratings changed in the early to mid-1970s.)
In 1973, the 170 was replaced by a 200 cu in (3.3 L) straight six, power steering and automatic transmissions were made optional, and sales spiked to 26,300. By then, however, Blazer sales were double those of the Bronco, and International Harvester had seen the light and come out with the Scout II that was more in the Blazer class. By 1974, the larger and more comfortable vehicles such as the Jeep Cherokee (SJ) made more sense for the average driver than the more rustically oriented Bronco. The low sales of the Bronco (230,800 over twelve years) did not allow a large budget for upgrades, and it remained basically unchanged until the advent of the larger, more Blazer-like second generation-Bronco in 1978. Production of the original model fell (14,546 units) in its last year, 1977.
