IndyCar penalizes and rescinds Chevy penalties

INDIANAPOLIS (AP) IndyCar has penalized Chevrolet for changing an engine too soon in Juan Pablo Montoya's car at last weekend's Detroit Grand Prix.

Chevy was docked 10 points Tuesday in the race for the engine manufacture championship. Chevy had previous penalties rescinded regarding torque and traction control. It will get 10 manufacture points back after that were taken away by IndyCar on May 12 because the changes were determined to be unintentional technical violations.
