In 1929, Packard revamped its Sixth Series by introducing a new 320ci engine for the Standard Eight, while reserving the larger, more potent 384.8ci eight for the prestigious Custom Eight and Deluxe Eight models. The 7th Series, unveiled in August of that year, brought incremental improvements, including a fresh Detroit Lubricator carburetor. Although the power output remained the same, the new carburetor enhanced flexibility.
Additionally, a dual-belt water pump was introduced, necessitating a one-inch increase in both wheelbase and hood length. A four-speed manual transmission became standard, featuring a special extra-low gear designed for navigating through deep mud or snow. Moreover, a convenient one-shot Bijur chassis lubrication system was incorporated, ensuring a smooth and refined ride.
As customary, a wide array of body styles were available, ranging from sporty roadsters and convertibles to luxurious formal limousines. Notable coachbuilders such as Lebaron, Deitrich, Rollston, and Brewster offered semi-custom coachwork options, while Packard’s in-house body shop crafted bodies renowned for their exceptional quality and style, befitting the prestige of their underlying engineering.
