Batman is shown driving a red car in his debut story in "Detective Comics" #27. The red car was never mentioned by name as the Batmobile. Although the Batplane was introduced in "Detective Comics" #31, the name "Batmobile" was not applied to Batman's automobile until "Detective Comics" #48 (February 1941). The car's design evolved in early Batman stories. It became a "specially built high-powered auto" by "Detective Comics" #30, and in "Batman" #5 (March 1941), it had a bat hood ornament and a darker exterior color. The predominant designs settled on a large, dark-colored body and bat-like accessories such as large tailfins scalloped to resemble a bat's wings.
