Microsoft Game Studios today announced the line-up of more than 50 American production cars that will be included in "Forza Motorsport 2," nearly half of which will be making their Forza debut when the game launches worldwide in May.

Whether it's new interpretations of muscle cars from the past like the 2007 Shelby GT 500 and old classics like the 1969 Camaro SS Coupe or today's hottest sports cars like the 2006 Chevy Corvette Z06, one of your favorite American sports cars is sure to be on the list. More world car lists to follow in the coming weeks.

We also wanted to elaborate on a very exciting new feature that will be included in "Forza Motorsport 2" - the Livery Editor. The livery editor adds a whole new level of customization to the game giving the Forza community the freedom to truly "build their dream vehicle" using any of the 300+ cars in the game. With the new and improved livery editor, gamers can put their own personal touch on every vehicle in their garage using unique paint schemes, personalized decals and logos, as well as their own art creations. Due to the Xbox Live Auction House, you will also be able to lock down the design on your masterpiece, put it up for virtual sale and share it with the world -- or at least the highest bidder. Who knows, maybe you'll be lucky enough to see that your next great creation helped some lucky member of the global Forza community make it to the top of the leaderboard!

For more details on the Livery Editor or the Auction House, cruise over to and have a look at this week's Pitpass Report. You will also be able to find updates on Turn 10's efforts at Game Developer's Conference this past week in San Francisco as well as screen shots of a few of the American production cars.
