In Several Game Modes
(including Time Trials, some Public Events and some races in team events), it is possible to perform a Perfect Start. This will allow you to gain a small acceleration boost at the beginning of a race. Additionally, if you have the “START BOOST” tuning part equipped, performing a perfect start will trigger the start boost’s rocket power and allow you to pull ahead of the competition. To perform a perfect start, you must rev your engine during the countdown by holding the accelerator pedal. The goal is to raise the RPM gauge so that the needle is sitting within the green section (the green display should glow up in a brighter green) on the gauge as the countdown ends and the announcer declares “Go!“.
Note: The Tuning Part Start Boost can not be activated in Adventure Mode!
