The Archie Sonic? Yes. Definitley. Game Sonic as we've seen so far? Could be.

After that you're left exclusivley to opinion and personal contemplation. I've always just held that Sonic typically/"his thing"/cruise-wise moves faster than the speed of sound, though if he called for, it he could surpass light as well. Super Sonic moves faster than the speed of light, and any incarnation  beyond has no limit on speed. For his individual body parts I don't doubt that he can move them much faster, or by using different innovative techniques he can move his entire body faster with even less effort per se than running.
