CSR Racing offers an online Multiplayer Mode, where a player has to spend Cash to enter a room with six opponents.

Multiplayer mode is divided into 20 seasons and each season lasts for 20 days. After a season ends, players are rewarded on the basis of their position on the leaderboard.
Beating all 6 opponents wins the player a "win streak". Beating 4, 5 or 6 racers will earn you 1, 2 or 3 cards. Cards may contain fuel, free upgrades, Cash, Gold, or parts to certain Pro Cars. Pro Cars can be constructed out of parts collected throught the cards and raced with.
Multiplayer rating is through Respect Points or RP. Higher RP earns you a higher position in the Leaderboard.
