Stewart pays Indy a friendly visit

INDIANAPOLIS -- Tony Stewart hasn't lost his passion to win the Indy 500.

But he may never get that chance racing stock cars.

The two-time NASCAR champion returned to Indianapolis Motor Speedway on Wednesday to help Chevrolet unveil its new midget-car engine, an appearance that prompted another round of questions about Stewart's plans and whether they might include IndyCars.

"There's a part of me that thinks running at Indy and in IndyCar is a chapter of my life that is closed," he said. "Then there is the emotional part of me that says, 'Never say never.' I don't know if I'll ever get in an IndyCar again, but if that happens, it's going to be a long way down the road because I have a lot of commitments on the NASCAR side."

Many believe Stewart, who turns 37 on May 20, is looking to move from Joe Gibbs Racing, in part because he has long ties to Chevrolet, and JGR is now using Toyotas. Stewart remains winless this season after winning 32 times in his first nine years on the Cup circuit.
