SPD

SPD is a game mechanic that appears in the Sonic the Hedgehog series. It is a speed measurement used to rate Sonic the Hedgehog's velocity.

Overview

In the Xbox 360/PlayStation 3 of Sonic Unleashed, whenever Sonic passes a Star Post during daytime Action Stages, the checkpoint will clock how fast Sonic is going and measure his velocity in SPD.

Trivia

It is unknown if "SPD" is an abbreviation of the word "speed", a recurring measurement for velocity in the Sonic Riders series, or an acronym.
