Asphalt 5, NFS: Undercover, the upcoming "Raging Thunder 2". I can't think of any more at the moment, but Asphalt 5 is probably the most similar to Burnout.
u chewbs dnt evn now whm ragin thondfer came ot! LOL jk anyways raging thunder was really impressive when it first came out (before the appstore). It was released in FW 1.1.3 believe and I thought it was THE SHIT! anyways whe the appstore came out (along with super monkey ball) we noticed all our 1.1.4 jailbreak apps sucked compared to the future of iPhone games.
Raging thunder 2 is gonna be the best thing that comes to what you want... unless you want Empty City
