1985 Porsche Batmobile

The vehicle that became the Batmobile was introduced in Detective Comics #27, the first Batman story. Originally, the vehicle was a simple red convertible with nothing special in its functions. Although the Batplane was introduced in Detective Comics No. 31, the name "Batmobile" was not applied to Batman and Robin's automobile until Detective Comics No. 48 (February 1941). Other bat-vehicles soon followed, including the Batcycle, Batboat and Robin's Redbird.
The car's design gradually evolved. It became a "specially built high-powered auto" by Detective Comics #30, and in Batman #5, it began featuring an ever-larger bat hood ornament and an ever-darker paint job. Eventually, the predominant designs included a large, dark-colored body and bat-like accessories, including large tailfins scalloped to resemble a bat's wings.
Batman No. 5 (Spring 1941) introduced a long, powerful, streamlined Batmobile with a tall scalloped fin and an intimidating bat head on the front. Three pages after it was introduced, it was forced off a cliff by the Joker to crash in the ravin. However, an identical Batmobile appeared in the next story in the same issue.
