Re-Volt 2 was the original name for Re-Volt's spin-off, RC Revenge.
When Acclaim announced RC Revenge in January 2000, they originally gave it the title of Re-Volt 2, and later on in the year for North America the game was re-titled to Re-Volt 2: RC Revenge with just Re-Volt 2 remaining for Europe.
By the time the game was released, Acclaim changed the name of the game to simply RC Revenge for all regions. However for the Memory Card icon the game was still refered to Re-Volt 2.
It was also called as Re-Volt 2: Pocket Rockets.
