Slipstream



The slipstream is an important gameplay mechanic that has appeared in Sonic Riders and Sonic Riders: Zero Gravity. It is a region of moving air created by Extreme Gear racing at high-speeds. This "moving air" can be surfed on like a track that accelerates other players riding on it.

Sonic Riders
The slipstream mechanic first appeared in Sonic Riders where it is under the name "Turbulence". Riding on the turbulence can help the player in overtaking leading opponents. The player is prompted to move the control stick left and right to accelerate. Sometimes, the player can perform Trick Actions while riding on the turbulence to gain Air.

Sonic Riders: Zero Gravity
The slipstream mechanic reappeared in Sonic Riders: Zero Gravity, but it only appears when leading players make a curve. Like in Sonic Riders, the player will accelerate while riding on the slipstream path and can launch themselves into the air to perform Air Tricks. This action can also be used to access shortcuts including "Wall-Routes" using Gravity Control and Air Ride sections.

In addition, riders racing on Yacht-type Extreme Gear uses slipstreams in order to accelerate while riding directly behind an opponent, otherwise known as "drafting".
