Turbo is a gadget available to Racer in Rivals. It gives players a high speed boost for a short period of time, albeit at the cost of making the car more difficult to handle and it restricting your vision.
Although it cannot be deactivated at will after it has been triggered, the Turbo boost will be cancelled if the player comes into contact with too many obstacles or crashes the car. On the other hand, if you manage to maintain full boost without taking damage you will receive bonus points.
