Throughout the 1940s, the Batmobile was generally drawn as a late 1930s/early 1940s two door sedan with a bat mask over the front grille, and a large vertical bat fin on the roof of the car. Beyond that, there have been several variants of the car, including the presence (or absence) of front and rear bumpers, front and rear fender skirts, a horizontal stripe at the headlight level, exhaust headers, a roof-mounted spot light, and vertical grille openings on either side of the mask.
In addition, the shape of the car varied, and was shown with headlights both on the front of and on top of the fenders (1940 Ford/1940 Chevrolet styling, respectively). The car was also sometimes drawn as an earlier 1930s sedan with wider, more sweeping fenders, a boxier midsection, and a longer hood. A "standard" Batmobile design wouldn't be adopted by the majority of artists until 1944.
