INDIANAPOLIS (Reuters) - The heartbreak of Niki Lauda's death has washed over the Indianapolis 500 paddock this week but there are no formal tributes planned to honor the three-times Formula One world champion, IndyCar said on Friday.

Although Lauda never raced IndyCar, the Austrian touched many lives across the North American racing scene, from team owner Roger Penske to the polesitter of Sunday's Indianapolis 500, Frenchman Simon Pagenaud.
