Grey’s Anatomy star Patrick Dempsey showed off his handsomeness, er, atuo racing stills at the Rolex Grand-Am Series Brumos Porsche 250 at Daytona International Speedway at Daytona Beach, Florida on Thursday afternoon.

Patrick Dempsey, 42, has been racing in his No. 40 Hyper Sport Mazda RX-8 and loving it, saying, “It allows the athletic side of my nature to come out. It’s such a nice departure from Los Angeles and Hollywood."

“The situational awareness is basically the same,” Patrick Dempsey said.

“In acting, you have to be aware of the camera. You have to have a sense of situational awareness, of what’s going on in front of you, what’s going on in behind you. There’s aggression and you have to be in control.”
