Rockstar has announced the latest batch of rewards and bonuses for Grand Theft Auto V. This week, players can earn extra cash and RP from GTA Online's new Motor Wars mode, as well as snag discounts on some powerful cars and vehicle armor.

From today until September 11, players can earn double GTA$ and RP by playing Motor Wars, a new Adversary mode that was introduced in last week's free Smuggler's Run expansion. Motor Wars drops four teams of up to 28 players into a warzone and has them vying for control of a weaponized vehicle while the battleground shrinks around them.
