chunk: Speed Racer is an 18-year-old whose life and love has always been automobile racing. His parents Pops and Mom run the independent Racer Motors, in which his brother Spritle, mechanic Sparky, and girlfriend Trixie are also involved. As a child Speed idolized his record-setting older brother, Rex Racer, who was killed while racing in the Casa Cristo 5000, a deadly cross-country racing rally. Now embarking on his own career, Speed Racer is quickly sweeping the racing world with his skill behind the wheel of his brother's cars, the Mach 5 and his own Formula One car the Mach 6, but remains primarily interested in the art of the race and the well-being of his family.
