Robbie Maddison to Rally at X Games 17

This summer's X Games rally lineup is starting to look more like an action sports all-star challenge than a Rally America race. Wednesday afternoon, another action sports star not known for his skills on four wheels announced he plans to compete in this year's race. Freestyle motocross star Robbie Maddison, who is known for his distance-jumping records and innovative freestyle tricks -- and for launching his dirtbike atop the Arch de Triumph in Vegas on New Year's Eve 2009 -- is the latest action star jumping into the rally scene.

At the Chicago Auto Show Wednesday afternoon, Maddison unveiled his RMR Hyundai Veloster, a brand-new model from the Korean automaker, which he plans to race this July. Maddison's Red Bull teammate, Rhys Millen, will compete in the 2011 U.S. rallycross championship in a 500 horsepower AWD Veloster rally car and rally champ Marcus Dodd will also join the team, driving the same setup as Maddison.

But while this new challenge means logging heavy seat time in the upcoming months, Maddison says it will not affect his freestyle plans at summer X -- he's the 2010 Best Trick silver medalist -- or X Fighters. "Bringing the heat on 2 and 4 this yr!!" Maddison said via Twitter, a few moments after the announcement. "I'm stoked. Thanks to Rhys Millen and team Hyundai, it just got a whole lot more exciting."

At last month's Winter X Games, snow-and-skate star Shaun White also announced his plans to learn to drive a rally car and unveiled his No. 86 Subaru rally car, which he could potentially line up this summer alongside the likes of Brian Deegan, Travis Pastrana, Dave Mirra and Ken Block. And now add Maddison to that list.

Check back later today for an interview with Maddison.
