Batmobile tumbler military camouflage
* Length: 15 feet (4.57 m)
* Width: 9 feet 4 inches (2.84 m)
* Weight: 2.5 short tons (2.3 t)
* Acceleration: 0-60 in 5.6 seconds. Under full acceleration, the car could actually rise up on its front "legs" while the front wheels stayed planted on the ground creating an effect like a giant spider.
* Engine: 5.0 liter Vauxhall/GM engine capable of 500 horsepower (370 kW). The jet engine and vector controls could jump up to 6 feet (1.8 m) vertically.
* Fuel: The "jet engine" on the back of the car was fed by propane tanks.
* Tires: Super swampers tires standing 44 inches (1,100 mm) tall (via titanium axles) in the rear and Hoosier dirt tires on the front.
 Production process
Nathan Crowley, one of the production designers for Batman Begins, started the process of designing the Tumbler for the film by model bashing. One of the parts that Crowley used to create the vehicle was the nose cone of a P-38 Lightning model to serve as the chassis for the Tumbler's jet engine. Six models of the Tumbler were built to 1:12 scale in the course of four months. Following the scale model creation, a crew of over 30 people, including Crowley and engineers Chris Culvert and Annie Smith, carved a full-size replica of the Tumbler out of a large block of Styrofoam, which was a process that lasted two months.
The Styrofoam model was used to create a steel "test frame", which had to stand up to several standards: have a speed of over 100 mph, go from 0 to 60 mph (97 km/h) in 5 seconds, possess a steering system to make sharp turns at city corners, and to withstand a self-propelled launch of up to 30 feet (9.1 m). On the very first jump test, the Tumbler's front end collapsed and had to be completely rebuilt. The basic configuration of the newly designed Tumbler included a 5.7-liter Chevy V8 engine, a truck axle for the rear axle, front racing tires by Hoosier, rear 4x4 mud tires by Interco., and the suspension system of Baja racing trucks. The design and development process took nine months and cost several million dollars.
With the design process completed, four street-ready race cars were constructed, with each vehicle possessing 65 carbon fiber panels and costing $250,000 to build. Two of the four cars were specialized versions. One version was the flap version, which had hydraulics and flaps to detail the close-up shots where the vehicle propelled itself through the air. The other version was the jet version, in which an actual jet engine was mounted onto the vehicle, fueled by six propane tanks. Due to the poor visibility inside the vehicle by the driver, monitors were connected to cameras on the vehicle body. The professional drivers for the Tumblers practiced driving the vehicles for six months before they drove on the streets of Chicago for the film's scenes.
The interior of the Tumbler was an immobile studio set and not actually the interior of a street-capable Tumbler. The cockpit was over-sized to fit cameras for scenes filmed in the Tumbler interior. In addition, another version of the Tumbler was a miniature model that was 1:5 scale of the actual Tumbler. This miniature model had an electric motor and was used to show the Tumbler flying across ravines and between buildings. However, the actual race car was used for the waterfall sequence.
