The Model 1005 Packard shared eleven different body styles with the Super Eight which had the same length. For Customer’s wanting more, Packard prepared their custom Twelves on the longer Model 1006 chassis.

In January of 1933 Packard launched the 10th series Packards and with it the Twin Six from 1932 became the Twelve. The shorter Twelve of 1933 had a 142 inch wheelbase and was available with 11 different body styles.

Numerous design details were new for the 10th series Packards of 1933 including a new front grill which was uniform across the entire range. Bullet headlights and 17 inch wire wheels also standard.

Inside the 10th series cars had increased insulation. The closed cars had a more raked front windscreen and tilting door windows on closed models which were dropped one year later.

The 10th series chassis was redesigned to sit lower which let the Packard designers raise the beltline on the doors and have smaller windows. This gave the 1933 cars a sleek appearance.

Specific upgrades to the V12 engine included an automatic choke with fast idle, a 10 gallon radiator tank and a 12-inch single dry plate clutch with optional free-wheeling system.
