In Christopher Nolan's Trilogy, The Batmobile is no longer a street demon with little use off-road. Nicknamed "The Tumbler," Batman's vehicle of choice appears to be influenced by a Stryker armored combat vehicle. However, Strykers can only travel 62 MPH, so they have a way to go to match The Tumbler. There have also been cars with jet engines attached to them - for better or worse. The Tumbler also featured rear-facing cameras (found in family cars today) and dozens of weapons (not found in today's cars).
The Batpod made a splashy debut in The Dark Knight by making a 90 degree turn by simply swinging to the side and letting its wheels flip over. Surprisingly, this is entirely plausible. Several prototypes have existed for years where an electric vehicle has its engine based the wheel, allowing the whell to make such a spectacular movement without cutting its connection to the engine. However, the Batpod would need some sort of electric steering setup, as the tumbling wheels would not allow for conventional steering. The bike is actually steered with shoulder sleeves and would take some time to get used to - so Catwoman probably wouldn't be able to pick it up so easily like she did in The Dark Knight Rises.
The Bat was the new vehicle featured in The Dark Knight Rises. Several VTOL (vertical takeoff and landing) aircraft exist in the military, one of the most famous being the Harrier Jump Jet. So while similar aircraft can be found in the world, there are none quite like The Bat, which has its main rotor on the bottom of the center of the aircraft - and that is the key issue where physics are involved. "Think of the problem of balancing a broomstick on your palm," a project manager from U.S. military told InnovationNewsDaily. The other issue is that such power will definitely flatten anyone around or below the vehicle as it went by. So while The Bat looks cool, don't expect a real version anytime in the near future.
