The on-board laboratory was lost, leaving only a two-passenger compartment under the dome. The car has also lost many of the curves of the previous car, being essentially a very long, thin box with the dome, fin, and "bat nose" features added. It retains many of the features of the previous car, with the major exception being the now separate dome over the passenger compartment. Though very similar in design to the 1941 car, the progression of the 1950s saw the Batmobile change again for the sake artistic simplicity hence, the "bubble dome" Batmobile was created. It was also the last car used before the now famous Batmobiles with the bat-masks and roof fins. Several "Proto-Batmobiles" had appeared in comics by this point, though this was the first to use the name.

The bat mask did not exist yet, but the car did sport a small "bat" hood ornament. Most of the design was based on the 1936 Cord, though the nose of the car looked more like that of a Lincoln or similar car. Before the familiar bat-finned cars, the title "Batmobile" was first used on a red convertible in Detective Comics #48 in February 1941.
