- The HW Prototype 12's body appears to be heavily inspired by the 1993 McLaren F1.
- HW Prototype 12 is the Prototype car Dr. Peter Justice had designed in Hot Wheels: Velocity X. The car's speed was capable of bending the light around it to make it look invisible, and could also be used for time travel. Otto Von Diesel, however, stole the car and Dr. Justice had his son Max disable and retrieve it.
- Its color in this game follows a similar color to the 2002 First Editions variant.
- It is also the fastest car in the game, with a regular top speed of 184 mph (296 km/h).
- The car was seen multiple times in Hot Wheels: World Race; it's first appearance is after Kurt Wylde's cover was blown and prior to the last leg of the World Race.
