Chevy with 3 engine failures to start Indy 500 practice: 'Hopefully the bad luck's out of the way'

INDIANAPOLIS — After just two days of Indianapolis 500 practice, one of the race's engine manufacturers has experienced concerns. Chevrolet, which is responsible for 18 of the 33 engines in the race, has already replaced three engines through two practices at Indianapolis Motor Speedway . On Tuesday, the first day of practice, Ed Carpenter Racing's Ed Carpenter and Team Penske's Scott McLaughlin had their engines replaced, although a Chevrolet spokesperson said it was "not the same issue.

" Wednesday saw Carpenter's teammate, Alexander Rossi, also have his engine changed after practice, as Rossi's original engine was sent back to Detroit, the location of General Motors' headquarters. "I am concerned," Rossi said Thursday morning. "It's not only Ed and I, there's been two others as well.

We don't have the full information as to are they the same failures? Is it something that's a batch thing? All that I know is that Chevy is just as focused on making sure that we can have a strong month.

We know that, for the most part, we're the engine to beat, so hopefully the bad luck's out of the way. " Chevrolet declined to comment on the engine failures, as its leaders were in meetings Thursday morning to get to the root of the issue. "Those things tend to happen here and there," said Arrow McLaren's Ryan Hunter-Reay, driver of the No.
