In 2002, Renna signed with Kelley Racing to be its test driver in the IRL, and was the driving coach and spotter to actor and Infiniti Pro Series participant Jason Priestley. Renna competed in seven races for Kelley Racing before signing a contract to drive for Chip Ganassi Racing in the 2004 IndyCar Series. During an October 2003 tire test at Indianapolis Motor Speedway, Renna was killed instantly in a collision with a retaining fence. He was the first driver to be killed in an accident in the IRL since Scott Brayton died at the 1996 Indianapolis 500. As a consequence of Renna's death, car speeds and horsepower were reduced through a reduction in engine sizes and aerodynamics were altered in a bid to prevent cars becoming airborne. A memorial fund and IRL award were named after him.
