Speed Racer (Gō Mifune) is the title of the Japanese anime "Mach Go Go Go," which explains why the hood of his car and his helment has the letter "M" designed on it. It was first created by anime pioneer Tatsuo Yoshida (1933–1977) as a manga series in the 1960s and made the jump to TV as an anime series in 1967.

I have looked at so many websites trying to find this answer and I have not found anything. I will keep trying, but it seems to me that the answer is nowhere to be found. Sorry.

The above answer is a great answer that got lost in limbo because the asker never chose it as best, and because it was the only answer, it never went to a vote. I'm forcing it to a vote and asking you to vote for it as the best answer. Let's reward those who take the time to give thoughtful answers!\n\nJennyinJamaica
