- Tony Stewart (@TonyStewart) May 27, 2014Stewart broke his right leg in a crash in a sprint car race in Iowa in August that sidelined him until February preparations for NASCAR's season-opening Daytona 500.
He said on Twitter that driving the car again "was a huge day for me." In a reply to a fan, he acknowledged that he indeed had butterflies, "but it felt like an old pair of shoes."
Stewart also posted that the car had safety improvements to the torque tube to prevent an injury like the one he suffered.
