User blog comment:Narendra Modi/Sonic vs Flash/@comment-4803039-20140531020903

Okay....there are several videos on youtube that attempt to figure Sonic's speed, and each one tends to one-up each other. Most recently GNoggin pointed out that Sonic is capable of accelerating 2340.6 m/s.

It's important to note that Flash is capable of tapping into the Speed Force and has ran into several issues with speed and time in the past.
