The IndyCar series has decided to introduce the use of a 'push to pass' system like the one that was used in the Champ Car days.
That move follows the implementation of various aerodynamic options for teams to use from this weekend's Kentucky Speedway race. But it has now gone further and introduced a power boost system in conjunction with engine supplier Honda. Each driver will now be able to access increased engine speed and a power boost of 5 to 20 bhp for a limited time in each race with the amount of additional power depending on whether drivers are in fuel-conservation mode when they activate the system. The system is similar to the push to pass device employed in Champ Car during its final seasons, but IRL officials admitted that the effect would not be as dramatic.
