Codemasters is working with the FIA World Rallycross Championship on a future update for DiRT Rally.
While further details on the upcoming expansion won't be revealed until this weekend, the World RX update looks set to introduce a new Rallycross mode and Höljes Rallycross circuit, and will be available at no additional cost to all existing players.
You can see the first screenshots through here.
DiRT Rally received its second major update earlier this week with the new Tarmac Terrors pack, which introduced a brand new German rally and 5 new cars.
Besides Rallycross, future updates are set to introduce PvP multiplayer and - if you ask really nicely - monster trucks.
