Hmm... here are a couple games off the top of my head. Full Auto is a superb combat racing game, one of my favorites on the system. Though I am not too sure on the online community, so if it is a big component to your racing experience, then I would rent it first. Then there is Burnout Revenge. I know you said you didn't quite like the series, but this is an arcadey and satisfying experience that is far removed from the open world Burnout Paradise. Another game by them that came out recently is Need for Speed: Hot Pursuit. I personally haven't picked up the game, but based on the gameplays and reviews, it looks to be an entry in the series that is actually good. The most recent racing game that I played (the demo, anyway) is Driver: San Francisco. It doesn't have vehicular mayhem by any means, but it is quite intriguing, as you can shift into other people's cars and take control using some sort of telekinesis, which makes for some interesting gameplay. Sorry I couldn't have been more help, but I am more knowledgeable on the PS3 racing scene, my 360 having a second RRoD after all.
