Ladies and gentlemen, start your engines! No, not you, Silver-level Xbox Live subscribers. You leave your engines firmly in the off position. We'll get to you in a second. Everyone else: Engine's on! The demo for Forza Motorsport 4 is now live for paid Gold subscribers, and can be grabbed from the Spotlight reel on the dashboard. If you need inspiration for the big race, we suggest checking out this debut UK trailer, which just happens to be narrated by Top Gear's Jeremy Clarkson. (Rad!)

Okay, Silverlings: You'll get your chance to play the demo this Friday. We suggest you spend the next four days thinking about your pathetic lot in life, and how you can improve it.
