I don't know but Batman Begins is the best superhero movie ever made IMO..

Nathan Crowley (one of the production designers) and engineers Chris Culvert and Annie Smith: "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 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. 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."
