Mach Speed ( is a move used by ブーストダッシュ Būsutodasshu , lit. "Boost Dash") ? Sonic the Hedgehog that has only appeared in as one of Sonic's custom moves. It is a move that gives Sonic a short boost of speed. It can only be used after Sonic obtains the Sonic the Hedgehog (2006) Blue Gem.
In order to use Mach Speed, Sonic has to possess the
Blue Gem upgrade. When Sonic is in possession of it, the player has to select the Blue Gem with the directional pad and can use it by pressing / .
When using this move, Sonic can perform a "Super Sonic Boost Dash" that makes Sonic perform a fast, but very brief dash that increases his speed to its maximum. If Sonic runs into an obstacle while dashing however, he will fall down on the ground for a second.
The mechanics of the Mach Speed is similar to the Mach Speed Sections found in certain levels of Sonic the Hedgehog (2006), though it is not specifically the same as Sonic does not lose any Rings when he collides with objects.
