INDIANAPOLIS (AP) -- The IndyCar Series says it will no longer penalize teams for certain engine changes.
IndyCar said Monday it has added a rule that allows changes in cases of engine failure during on-track team, rookie, manufacturer and straight-line tests. The rule will not apply to engine failures during open tests at Pocono, Mid-Ohio or Sonoma.
Helio Castroneves had the pole for Sunday's race at Iowa Speedway, but started 11th after an unapproved engine change and finished eighth.
