The Batmobile is Batman's personal automobile and primary mode of land transportation. It has been redesigned several times. It also has a passenger seat for an accomplice, usually his sidekick Robin. It is housed inside the Batcave alongside all of Batman's other selection of vehicles.
Little is known about the first Batmobile. Because of mechanical difficulties, Batman was forced to abandon it and had a more robust vehicle designed and built by Earl Cooper, an out-of-work automobile designer with a reputation as a troublemaker in the industry.
Earl Cooper designed and built a new Batmobile (inspired by a vehicle of similar design Bruce saw at the Gotham's World's Fair during a date with Andrea Beaumont) that included such items as a turbine jet, grappling hook, ejection seats, on-board navigation and computer with video uplink, oil slick and caltrops. The next was destroyed by The Penguin. The second was built after Penguin's defeat with several upgrades. This was used until it was destroyed bare handed by Bane. Another was built after this.
Among the features were: smoke and oil dispensers, wheel slasher hubs, a missile rack, tear gas dispensers, ejection seats, titanium alloy wheels and body panels, and reversable jet exhausts. It also had a "shield" mode to prevent people from tampering when the car when it was left unattended, though it was not as overt as the "cocoon" used on Tim Burton's 1989 Batmobile. Despite the obvious presence of the jet exhaust, the show frequently used sound effects from a reciprocating engine for the Batmobile's driving scenes. This, plus direct views of the engine, suggest that the car uses a large piston engine for primary power, and an auxillary jet for high-speed acceleration.
