The One-Twenty signified the first time that Packard had entered into the highly competitive mid-priced eight-cylinder car market.

The One-Twenty, weighing in at 3,688 lb (1,673 kg),[4] was powered by an all-new Packard aluminum-head[4] L-head inline eight producing 110 bhp (82 kW) at 3850 rpm.

The line also added a wood-bodied station wagon, Touring Sedan and limousine built on a 138 in (3,500 mm) wheelbase[7] and priced under $2,000.

Again, the One-Twenty came in a full array of body styles, including a semi-custom Convertible Victoria by Howard "Dutch" Darrin.

In its final year as a model, the One-Twenty lost a number of body styles to the expanded One-Ten line of cars.
