2011 IZOD IndyCar World Championship
The 2011 IZOD IndyCar World Championship was the final race of the 2011 IZOD IndyCar series schedule. The event took place at Las Vegas Motor Speedway in Clark County, Nevada on October 16, 2011. The race was stopped following a major accident triggered by drivers trying to avoid light contact between Wade Cunningham and James Hinchcliffe. 15 cars were involved in the wreck, which resulted in the death of two-time Indianapolis 500 winner and 2005 series champion Dan Wheldon. After a delay of over two hours, IndyCar decided to abandon the remaining 188 laps after word of Wheldon's death was relayed to the drivers, though the drivers did complete a five-lap salute in honor of Wheldon.

For the first four runnings, the race was advertised as a 500 km race. Starting in 1997, the race was moved to a night race. In 2000, it was moved from the fall to the spring, and returned to a day race. After 2000, the race was removed from the IndyCar Series for a decade.
