Microsoft has released a free pack featuring three new cars for Project Gotham Racing. The Cadillac V-Series Collection is clearly a marketing device for the automobile manufacturer, but we can't grumble at a free content download. "The three Cadillac V-Series cars include the 400 horsepower CTS-V, which in racing form won both the manufacturers' and drivers' championships in the 2005 SPEED World Challenge GT series against the likes of some of the most powerful vehicles in the world; the 443 horsepower XLR-V, which is the quickest and most agile Cadillac ever offered; and the 469 horsepower STS-V, the most powerful production Cadillac ever made. In short, horsepower is not an issue when it comes to these stylish and fast Cadillac cars." Says Microsoft in one hell of a long sentence. Players who place within the top 100 on the Nurburging F1 track in any of these cars will be given an exclusive gamer picture. Source: Microsoft
