IndyCar: Push-to-pass made secret

IndyCar will no longer display push-to-pass counts and usage on timing screens in an effort to encourage overtaking on road and street courses.

Previously, the series' standard timing screen had included both the amount of push-to-passes that each entrant had left, as well as indicating in real time when each driver was activating the system.

That information will be removed for Sunday's race race in Toronto, with the change to remain in effect until at least the end of the season.

"Unfortunately, the information given to the teams on the push-to-pass function has tended to be used as a defensive measure," said Derrick Walker, IndyCar president of competition and operations. "The driver being overtaken activates his or her own P2P [push-to-pass] to defend – which defeats the intention of P2P, obviously.

"We will limit the availability of that information, which will make things interesting, particularly late in the race."

The push-to-pass system adds an estimated 50 horsepower per use, with each engagement lasting 20 seconds. Drivers are allocated 10 push-to-passes for each street and road course race.

Series officials will continue to monitor each car's push-to-pass usage from race control.
