Hudson introduced their 'step-down' unibody models in 1948, allowing the placement of the passenger compartment down inside the perimeter of the frame that was an integral part of the body. Passengers stepped down into a floor that was surrounded by the perimeter of the car's frame. This design made the car safer, gave more passenger comfort, and increased the handling of the car due to the lower center of gravity. The car was a foot lower than many of its contemporaries.
In 1954, the company was merged with Nash-Kelvinator to form American Motors Corporation.
This 1949 Hudson Commodore Six Convertible completed a 19 month restoration in April, 2009.
