 The engines proved themselves to be quite durable — there had been no engine failures at Indy from 2006 to 2010, which also lowered the number of crashes.Most of the engines, including those used for the Indy 500, are used for multiple races and were intended to last 1,200  miles (1,931  kilometers) between rebuilds.The Honda engines were only available via lease arrangement from Honda, which, for the 2010 full season, cost $935,000 U.S. per season, per car.
