Casa Cristo 5000

The Casa Cristo 5000 was a race that was held in the 2008 Speed Racer movie. Speed Racer and Racer X join the event with a modified Mach 5 to aid Taejo Togokahn in winning the race and breaking Royalton's fix. When word is spread about this, Cruncher Block bribes various drivers, including Snake Oiler, into taking out the three drivers and saving their money.

Background
A cross-country race, the Casa Cristo Road Rally spans two continents, three climate zones, and 5,000 km of the most winding and treacherous roads ever raced – from the arches and columns of the Muqranna through the Casa Cristo Cliffs, Zunubian Desert, and Maltese Ice Caves.

Though the WRL has made an effort to clean up rally racing, underhanded driving tricks including spearhooks, tire shanks and battery boosters make the Casa Cristo such a brutal test of endurance that it’s nicknamed the Crucible … but being first to cross the finish line automatically earns the winner an invitation to the prestigious Grand Prix.

Racer List
45 racers participated in the event. There's no list showing the driver names from Casa Cristo, but some can be noticed via analysis. Here's a list of the known ones, not counting members of the same team (besides the main characters):

Outcome
It was eventually revealed to the Racer family that Togokahn winning the race was not to expose Royalton's race-fixing to world, but to boost profits for their company. A furious Speed drives the Mach 5 to Thunderhead Raceway in the dark and accidentally wrecking Racer X.

Trivia

 * The title, Casa Cristo, is Spanish for "the house of Christ". The race may have gotten this infamous name for being the grave of various drivers in the past, seemingly including Speed Racer's brother.
 * A leg of the Casa Christo resembles the Stelvio Pass in Italy.
