Brad Keselowski won’t commit to racing Indianapolis 500

Just days after taking his first laps behind the wheel of an Indy car, could Brad Keselowski became the next driver to compete in the Indianapolis 500 and NASCAR’s longest race on the same day?

He isn’t dismissing the idea.

“I wouldn’t say yes or no,” Keselowski told SB Nation and Motorsport.com Friday at Iowa Speedway. “I would just say, ‘I don’t know.’”

Kurt Busch became the sixth driver in 2014 to contest the IndyCar-NASCAR “double,” racing at Indianapolis Motor Speedway during the afternoon on the Sunday of Memorial Day weekend, then the NASCAR portion at Charlotte Motor Speedway later that night.

Keselowski acknowledges seeing Busch, a fulltime Sprint Cup driver, finish sixth in the Indianapolis 500, indicates a driver with primarily a stock car background can be competitive racing an Indy car. Busch had never raced an open-wheel car previously.

“Absolutely,” Keselowski said. “You cannot look at Kurt and what he did and say, ‘That’s not something very possible.’

Keselowski tested for two-hours during a private IndyCar Series session Wednesday at Road America in Elkhart Lake, Wisc. He drove a Team Penske Chevrolet-powered Dallara around the 4-mile road course.

“I thought it went really well,” Keselowski said. “It took a little while to get up to speed, but I felt like at the end I caught on. We were probably 2 to 2.5 seconds off, which on big track like that is terrible. I felt like if I tested all day, though, I could get there.

“I definitely used a few curbs up.”

The idea of driving an Indy car is something that’s long interested Keselowski, and when team owner Roger Penske -- who also fields Keselowski’s NASCAR team -- offered the chance a couple of months ago, the 2012 Sprint Cup champion readily accepted. He then went to work adding 20 pounds of muscle to handle the strain an Indy car driver feels on their neck and shoulders due to the increased G-forces and spent countless hours in a simulator to gain familiarity with an open-wheel car.

Keselowski and Penske spoke immediately following Wednesday’s test, with Penske naturally wondering what Keselowski wanted to do next. Presently there are no other tests scheduled.

“It’s a great opportunity that I don’t know where it’s going to go,” Keselowski said. “It’s one of those things where you open a door to see what’s on the other side and you don’t know if you’re going to walk through that door or just peeking -- that’s kinda where I’m at.”

And now that Keselowski has peered through that door?

“Of course, whenever you look through it you want to go further,” he said. “But the key thing for me is I have a great opportunity right now at the Cup level and I have no intentions of quitting my day job.”
