Going 240 mph 'greatest feeling': Indy 500 champ

Inside Indy's winning circle with Hunter-Reay

Fresh off his dramatic Indianapolis 500 win, Ryan Hunter-Reay came to CNBC on Wednesday and brought his car.

He talked with "Squawk Box" about what winning the race this past Sunday meant to him, but also addressed the question he said everyone asks: How do you fit into the car?

"I'm one of the taller guys. It's a tight fit," he explained. "You kind of lay down in it. Doing 240 miles an hour in that is the greatest feeling in the world."

Hunter-Reay was the first American to win the Indy 500 in eight years. He only won by 0.0600 of a second.

"That's the great thing about the finish of this year's Indy 500, which is the second-closest in history, was at the end there I was going wheel to wheel with Helio Castroneves at 230-plus miles per hour," he described.
