Codemasters will offer a post-release demo of FUEL for PC, PS3 and Xbox 360 today.
The PC version will be available from the FUEL website at 2pm BST (UK time). The console versions may not pop up until later.
The demo opens Ocean Rush career event and Blitz Challenge. The former is a race for seven people and the latter is a race for one person and their clock.
Console versions will also have online play for two weeks from launch, either on the Tsunami Reef course with up to 15 others or on the Ocean Rush career event.
FUEL is set in a post-apocalyptic future where racers risk life and limb to win fuel, ironically. The game came out in early June but unfortunately we weren't massive fans.
