Hot Wheels: Velocity X (also known as Hot Wheels Velocity X: Maximum Justice in the PlayStation 2 version) is a vehicular combat video game released in 2002 by Beyond Games. There are versions for the GameCube, PlayStation 2, PC, and Game Boy Advance. The game is based on the Hot Wheels toy automobiles.

The story begins when The Hot Wheels car business, owned by Dr. Peter Justice, is robbed and bombed; the most vital items that were stolen being some computer disks on the formula Velocity X (a formula for a racing super fuel that allows cars to travel twice their normal speed) and a prototype Hot Wheels car (that runs on uranium and can turn invisible for short periods of time). In the GBA version, the story mode is simply races mixed with tasks given by the Professor such as destroying other vehicles and collecting items.

At the end of each, a boss is raced. In the GBA version the Challenges are Battle, where the player destroys opponents; and Tag, where the player rams opponents. The player begins with six vehicles, and three in the GBA version. The game has 27 additional vehicles that can be unlocked by successfully completing various challenges and missions. Each car is rated on its speed, grip, stunt, and armor.
