Fastest you can feasibly peg Sonic at is maybe 10 times the SoL at best due to the SPD in Unleashed with his full boost being faster than the LSD but that's legit the only thing beyond statements he has going for him and it could be attributed to game mechanics but meh. It's not enough to blitz but you could reason he's a bit faster than RD.

Not Twilight, though. The Light Speed Dash isn't even all that fast really, in Unleashed it only goes like 300-400 SPD while Sonic can very easily go faster than that by almost 10 times really quickly with his boost.

He's also been faster than light since CD as the whole time travel thing revolved around Sonic going faster than light when using the sign things.
