The filmmakers wanted to avoid computer-generated imagery as much as possible. So, the original conceptualization was done by mashing together parts from various plastic model toy kits to create a roughly 1:12 scale concepts. The resulting Lamborghini-meets-Hummer design was the result of six of the creations made over four months. From there, a giant block of styrofoam was hand-carved into a full-scale model that was used to create wooden molds for the 56 body panels. Then it was time to make the real deal.

Weighing in at about 5.000 pounds, the 9'4"-wide vehicle may actually not be as heavy as you'd expect. That's because the Tumbler you see driving around is merely a tube-frame chassis with carbon fiber body panels. Why use race car tech on a mere movie prop? The team wanted to ensure the Tumbler could reach a top speed of over 100 MPH and launch from 0-60 in five seconds. Of course, the car also had to consistently endure jumps of up to 30 feet without being damaged, so it had to be strong as well as fast. We're guessing they couldn't find a dyno big enough for the four 37-inch rear tires, but rest assured, the Wayne Enterprises-tuned Chevy V8 was churning out plenty of grunt. All said and done, the cars "only" cost about $250,000 each to build, so the studio ordered four constructed. Two were "race" versions for the action shots, one had an actual jet engine bolted in the back, and the other was for the elaborate flower petal-like cockpit. We wonder if they'd consider building a fifth, you know, for us to fight crime and hoon about in. [HowStuffWorks]

Responding to questions of plans to sell, Bob says:

No, not building this to sell. You wouldn't want to sell this if you had one, believe me. It's a once in a lifetime project.
I did this alone, no help. I have found with other things in the past that if you have help, the help often does not get it(parts) right, and you have to do it over 95% of the time, plus I like to work alone. All parts are scratch built, cept' tires, rims, brakes, engine, etc.. meaning all bodyparts, brackets, just about everything external on the car. Yes, I will do a batpod, and TDK suit for myself. I love building this stuff.

In addition to the exhibition lap, the Toyota cars will adopt special Dark Knight paint schemes, while the Jarno Trulli and Timo Glock's overalls will be made to look like Batsuits (no word on nipples). The Bat-Pod will also be in attendance, but possible due to its extremely un-motorcycle-like handling characteristics, it won't be ridden.

PRESS RELEASE

Panasonic Toyota Racing joins forces with The Dark Knight at Silverstone

Thanks to a partnership between Panasonic Toyota Racing and Warner Bros. Pictures, Hollywood is coming to Silverstone for the British Grand Prix weekend to celebrate the release of the event movie of the summer: The Dark Knight.

The much-anticipated film, which releases in cinemas across the UK on 25 July, is the follow up to the 2005 action hit Batman Begins. The Dark Knight reunites director Christopher Nolan and star Christian Bale, who again portrays the dual role of Bruce Wayne/Batman.

To mark the release of The Dark Knight, Panasonic Toyota Racing will adopt a new look at Silverstone this weekend. The Dark Knight artwork will feature on the TF108s and the overalls of Jarno Trulli and Timo Glock, as well as the team's motor home.

But The Dark Knight theme does not stop there. On show at Silverstone will be the iconic Batmobile and Bat-Pod vehicles, while some very special media events will bring the excitement of The Dark Knight to life.

The Batmobile will even take to the Silverstone track on Thursday evening for a demonstration run alongside the TF108, followed by some unique photo opportunities with the Bat-Pod and Jarno Trulli and Timo Glock.
