Start Line Boost

The Start Line Boost, also referred to as the Hi-Speed Start, is a move that appears in the Sonic the Hedgehog series and its spin-offs. It is a technique that gives the user a sudden speed burst at the start of a race.

Description
The Start Line Boost is a move that is performed with race cars. When performing this move, the user revs up their car just before a race starts. If done correctly, then the user's race car will take off at high speed when beginning the race. If done incorrectly however, the user will start off with a plodding disadvantage.

In gameplay, the Start Line Boost allows the playable character to charge up their race car with each count of the countdown time that appears at the beginning of each race. If the race car has been charged up properly, the playable character's race car will emit fire from its exhausts once the race begins, which automatically triggers an accelerating speed boost, thus giving the playable character a speed advantage early on in the race. The size of the Start Line Boost depends on how many times the player changes their car during the countdown, with three charges being the maximum. If the player mistimes their charge however, their Start Line Boost will reset. Also, if the player mistimes the charge on the final count of the countdown, their playable character will start off the race slowly momentarily, thereby putting them at a disadvantage.

Sonic & Sega All-Stars Racing
The Start Line Boost first appeared in Sonic & Sega All-Stars Racing. In this game, it is referred to as the Hi-Speed Start. Noticeably, on the console versions of Sonic & Sega All-Stars Racing, when revving up the race cars' Start Line Boost, their exhausts will spew out flames whose intensity depends on the number of times the race car has been charge up; with the first charge, the flames will be yellow; with the second charge, the flames will be blue; and with the third charge, the flames will be purple.

To perform the Start Line Boost in gameplay, the player has to press and release the Accelerate button with each count of the countdown timer.
