The Associated Press reports General Motors has pulled all 11 Chevrolet IndyCar engines from testing after racer James Hinchcliffe blew one during testing at Sonoma. GM evidently was concerned enough about the 10 other engines having similar problems that it decided to swap them all and face the resulting sanctions.

Under IndyCar's current rules, Hinchcliffe, driver of the will be penalized for the failure despite the fact that it had nothing to do with the driver. IndyCar prohibits engine changes until the units have reached a minimum of 1,200 miles, a figure that is set to jump to 1,850 miles after this weekend. IndyCar CEO Randy Bernard, meanwhile, maintains that the rule is meant to reduce costs for teams. He also pointed out that both Honda and Lotus have received similar penalties this season. But that hasn't stopped some from grumbling about the rules.

Until this point, Chevrolet has done exceedingly well this season, nabbing the first two poles and taking a victory at the season-opening race. The company currently holds the lead in the manufacturer's title with 18 points – six points ahead of Honda.

Hinchcliffe, meanwhile, says he's excited about the challenge that the engine swap presents. He, along with a smattering of other racers, will now start at the back of the pack, and Indycar's rulemakers have themselves a new controversy to contend with.
