Go Mifune

Ready to take on the most treacherous courses, Speed faces the most ruthless villains as he competes in races around the world in such real-life destinations as Japan, Egypt, and Mount Rushmore, and other worldly places like Sandoland, Abalonia, and Flathill. Speed races blind or without brakes, he sets a new land speed record and races the car no one could drive. Although important, winning races isn’t Speed's primary goal. Sometimes, he will intentionally lose a race to aid a total stranger, but more often, he will win a race while aiding the likes of Inspector Detector in whatever mysterious situation he encounters.

In the original Japanese Mach GoGoGo, his name is Go Mifune, in the 1997 Remake, his name is changed to Go Hibiki.
