The star of the hit show, Grey's Anatomy, is making a fast trip to Iowa this weekend. According to a spokesman, Patrick Dempsey and his team will compete at the Iowa Speedway in the Grand-Am Koni Challenge.

Last week, the 41-year-old "Grey's Anatomy" star competed in the timed 2.5-hour Grand-Am Koni Challenge GS sports car race on Sunday. Dempsey is a driver and part-owner in the pro-Am sports car series. Dempsey and co-driver Charles Espenlaub of Tampa finished sixth of 39 cars. It marked Dempsey's best finish in five Koni Challenge races. Maneuvering a sports car and going as fast as 170 mph give him more of a rush than filming dramatic scenes for his television show, Dempsey said.

There's only one possible hitch in the plans. Grey's Anatomy is trying to wrap up the season, and if they go into overtime, it could throw a wrench into this weekend's plans.

With cars that go straight from the showroom to the track, the Grand-Am Cup Series is racing in its most recognizable form - with everyday cars. The high-performance Sports Cars, Coupes and Sedans in the Series are modified for safety, so fans can see what a professional driver can do in a car they themselves might own.
