At the end of every lap the player is given one boost. This boost may be used at any time during a game (by pressing + or , depending on the selected control layout). A boost will dramatically increase a player's speed, but will decrease their ability to turn. A boost used before a jump will make the player jump farther, allowing the player to use a shortcut.
There are different ways to turn your vehicle without hitting the wall: or slide the vehicle in each direction and tapping the acceleration button ( or depending on the selected control layout) rapidly makes turning considerably easier. This is important because the courses in the game contain many sharp turns, sometimes 180 degrees.
