Scud Race Plus (スカッドレース プラス) is an expanded version of Scud Race, released in 1997 for Sega's Model 3 arcade hardware. This rare and unusual update was exclusive to Japan, though the game's region can be changed. When switched to the US region, it transforms into Sega Super GT Plus. On March 31, 2017, Sega Logistics Service officially ended support for Scud Race Plus machines.

Scud Race Plus is largely identical to the original Scud Race but includes a few additional features:

New track: Super Beginner
Mirror course: Hold the START button on the track select screen.
Time Lap mode: Hold the START button on the transmission select screen.
Extra cars: Available only in Super Beginner mode by holding the START button while selecting a car.
