X3M

The X3M is a contragravity speeder used for transporting passengers from point A to point B. Powered by a mass effect field, this vehicle is highly maneuverable and fast. A speeder can comfortably seat three passengers. Several are seen at the Transport Depot in Omega, and one is used for transporting Shepard and their team on a rescue mission to save Garrus from the gangs.

Trivia
This is the first speeder known by its designation, and is the third variant of this type seen to date.
