Actually, yes. Tatsuo Yoshida created Mach Go Go Go which then became anime and then crossed the sea to become Speed Racer.
The manga has been reprinted a few times...by NOW Comics back in the 80s and by DC/Wildstorm in 2000.
Wildstorm also produced an original mini-series (collected as a tpb, but it's hard to find) called "Born to Race" which was a prequel to the series.
Seven Seas Entertainment has a new Speed Racer manga series scheduled for Summer 2007 (www.gomanga.com)
So, yeah, besides being a pop culture icon there's plenty of comics connection to Speed.
