On May 18, the 15th Gumball 3000 rally will set off from Copenhagen, Denmark, with over 100 supercars crisscrossing Europe, taking in thirteen countries in six days. For most people, driving an Aventador or SLS Roadster would be an incredible experience, but the guys that run Gumball aren't most people. They have money. And time. Take Team Galag from Saudi Arabia, for instance. Having successfully crossed the line in LA last year in said supercars, it was felt that for 2013 something extraordinary was needed. The result: a custom-built, street-legal Tumbler.

Built from the ground up with the help of Parker Brothers Concepts, the 2.5-ton scale replica of the Batman Tumbler is no Hollywood prop. This thing is ready to complete the epic rally. Dubbed the TG1, the one-off creation boasts a full carbon-fiber body and at 5.3 meters in length, will take up as much road space as a Rolls-Royce Ghost. Powering the beast is a 3.8-liter twin-turbo V6 rated at 750 horsepower. That should be enough to propel it from 0-60 mph in 2.7 seconds, 0-100 mph in 5.65 seconds and give it a top speed of 200 mph. Ceramic brakes will have the duty of keeping the Tumbler within the speed limit.

Team Galag will accompany its Tumbler with another custom-built car, both of which will be revealed prior to the rally. Joining the Saudi Arabian team on the 3,000-mile run will be David Hasselhoff, Tony Hawk, Xzibit and Kimi Raikkonen, who will be hoping to make it to the crossing line in Monte Carlo on May 24, just in time for the Monaco Grand Prix. Kimi holds the fastest qualifying time on the street circuit at 1:13.532 and won the race for McLaren in 2005.
