The One-Twenty is an important car in Packard's history because it signified the first time that Packard entered into the highly competitive mid-priced eight cylinder car market. Packard enthusiasts view the One-Twenty and the Six/One-Ten models as the tipping points in which Packard began to cede its hold as the premier American luxury automotive brand.
The introduction of the One-Twenty (and later the Six/One-Ten models) was a necessary move to keep Packard in business during the final years of the Great Depression. The reason the company decided to forgo the development of a companion brand name to sell the less expensive models may have been linked to its single production line capability at its Grand Avenue manufacturing plant as much as to the expense of launching a new brand of automobile. By making the One-Twenty a Packard, the car could be brought to market quickly, and would afford buyers the cachet of owning a Packard.
This car introduced the independent front suspension to the Packard line. As could be expected from this prestige firm, the design had a special characteristic unique to Packard. The so-called "Safe-T-Flex" suspension was a unequal upper and lower A-arm type with the largest possible lower A-arm composed of two different arms bolted together at a ninety-degree angle.
The support arm was a heavy steel forging reaching a few degrees forward of lateral from the front wheel support to as close to the centerline of the car as is practicable. An integral pad socketed the helical spring, whose upper end reached a high frame cross-beam. A tubular, hence lighter, steel torque arm was bolted to the support arm somewhat inboard of the wheel to permit a sufficient steering arc. It reached the frame nearly at the dashboard with a spherical rubber bearing. The upper A-arm was conventionally welded and oriented parallel to the lower one. Between it and the frame was an old-fashioned horizontal shock absorber whose two cylinders were side by side.
The support arm carried all the load; the torque arm carried the accelerating and decelerating torque; the upper A-arm controlled the camber. Advantages claimed for the system included superior maintenance of wheel alignment from the wide spread of the lower A-arm, a permanent fixing of the caster angle, and an increased percentage of the braking force transmitted to the frame through the torque arm.
In its introduction year, the Packard One-Twenty was available in a broad array of body styles including two and four-door sedans, convertible and Club Coupe. The One-Twenty was powered by Packard's L-Head Eight cylinder engine producing at 3850 rpm. Prices for the car ranged from $980 for the three-passenger business coupe to $1,095 for the Touring Sedan. Introduced in January 1935, the car was an immediate success with consumers with Packard producing 24,995 One-Twenty's compared to 7,000 of all other type Packard’s for the year.
For 1936 Packard increased the displacement on the L-Head Eight, increasing its output to , making the car capable of clocking a top speed of . The One-Twenty added a convertible four door-sedan model which was the most expensive model in the range priced at $1,395. A total 55,042 units rolled off the line in 1936, the highest production that the One-Twenty would reach.
In 1937, the One-Twenty went up-market as company introduced the Packard Six, the first six cylinder Packard in ten years. For 1937 the One-Twenty broadened its model range and was now available in "C" and "CD" trim levels. The line also added a wood-bodied station wagon, Touring Sedan and limousine built on a 138" (inch) wheelbase and priced under $2,000. Introduced in September 1936, 50,100 units were produced during series production.
For 1938, the One-Twenty name was dropped and its model folded into the Packard Eight model range, and bringing the model name into parity with the Packard Six.
The series name of One-Twenty officially became hyphenated for model year 1940. Again, the One-Twenty came in a full array of body styles, including a semi-custom convertible Victoria by Howard "Dutch" Darrin. Introduced in August 1939, total model year output was 28,138 units.
In its final year as a model, the One-Twenty lost a number of body styles to the expanded One-Ten line of cars. The One-Twenty was available in Business coupe, Club coupe, two-door sedan, four-door sedan, convertible coupe, convertible sedan and two station wagon styles. Production sank to 17,100 units.
For 1942, the One-Ten and One-Twenty were dropped as model names and their models folded into the Packard Six and Packard Eight lines. In its seven years in the Packard line-up, the One-Twenty saw a total production of 175,027 units.
