From Destinypedia, the Destiny wiki
The Sparrow is a single-occupant vehicle used by Guardians, primarily for fast travel across long distances within a playable zone. Each Guardian is issued such a vehicle, which is stored aboard their jumpship and can be summoned for use as needed. Its stats can be improved within the game.
New Sparrows can be acquired from a few places; sometimes they appear as Loot (for example, finding all five Gold Chests in Old Russia will yield an uncommon sparrow), or purchased from a vendor, such as the Shipwright, Crucible Quartermaster, or Vanguard Quartermaster.
Sparrows can be summoned at every Patrol destination while in a public space, except for the Dreadnaught, and any Crucible map that allows vehicles. Sparrows are required for the Sparrow Racing League, which is the only dedicated racing activity in the game.
Sparrows all have a booster, used as their primary method of propulsion. The boost button is mapped to the aim button, while brake is mapped to the shoot button. Guardians can also give directions while on the sparrow using the D-pad: Forward (up), left, right, and stop (down).
Some sparrows have additional abilities. Sparrows with the evade ability can boost slightly to the side using the left and right shoulder buttons. This consumes boost energy.
Trick Sparrows: The EV-30 can use the evade ability while airborne to perform barrel rolls, which can regenerate boost energy upon a successful roll.
Overdrive Sparrows: The raid Sparrows come with an afterburner for extra speed. However, engaging the afterburner for too long will cause the sparrow to explode.
Standard & Custom Drives: Some Sparrows have various drives types of NLS Drive attached to them.
