During an Indy 500 practice run back in May, James Hinchcliffe suffered an injury that bled so bad he was, literally, drained and re-filled.  The first time I can think of anything other than the racing car itself getting a full on oil change.

Hinchliffe was given 14 pints of blood, and even more during surgery, while the human body only holds around 12. Hinchcliffe credited the rescue crew with saving his life for seeing the heavy bleeding and bypassing the on site medical facility to take him straight to the hospital for surgery.

"The suspension struck an artery and even before getting me out of the car, I had lost a tremendous amount of blood. From what I hear they skipped the infield medical center. They got me straight in the ambulance and straight to Methodist [Hospital] because they knew it was bigger than that.

Ryan Briscoe replaced Hinchcliffe in the Indy 500 but, Juan Pablo Montoya won. The Hinchcliffe wreck was the fourth involving drivers actually catching air during practices for the 2015 Indy 500.
