Scott Dixon, Josef Newgarden, Alexander Rossi and Pato O’Ward had been in motion on the Indianapolis Motor Speedway, utilizing the push-to-pass system at 1.5-bar to simulate the burst of launched vitality from a KERS unit.
IndyCar will change the present 2.2-litre twin-turbo V6s with KERS-supplemented 2.Four-litre twin-turbo V6s in 2023, with the goal being a mixed output of 900hp by 2025.
Friday’s trial run, with the 2 Chevrolet- and two Honda-powered vehicles working at common 1.Three-bar however with the drivers making use of brief squirts of 1.5-bar increase to simulate the KERS impact, supplied extra questions than solutions.
“We got here into immediately considering this is able to precipitate extra questions than solutions, and that’s most likely what occurred. In order that’s wonderful. We’re taking a look at how this might work in 2023 with the brand new hybrid system coming in,” stated Frye.
“We did be taught rather a lot. But it surely did additionally create loads of different questions.
“If you concentrate on 2023, along with the brand new engine – the two.Four-litre twin-turbo V6 which may have one other 100hp – the brand new hybrid system, too, may have the flexibility to have an extra 100 extra horsepower.
“So how does that work? With the push-to-pass system now we have with the present engine components, we will simulate slightly bit the way it might presumably work, which is what we tried to do immediately.
“I feel [the drivers] had some moments… going right into a nook – as a substitute of at 230[mph] they had been getting into at 236. There have been some totally different reactions, but it surely was actually good – good studying.”

Presently on ovals, the vehicles run at 1.Three-bar turbo increase and there’s no push-to-pass facility. The horsepower is elevated to 1.5-bar just for Quick Friday and qualifying weekend on the Indianapolis 500. On street and road programs, the vehicles run 1.5-bar commonplace, after which have as much as 200 seconds of push-to-pass 1.65-bar increase per race, producing an additional 60hp roughly.
“We obtained loads of information off the vehicles to offer us some course about which strategy to go along with,” stated Frye.
“Take into consideration the way in which we presently have push-to-pass – with the hybrid system that will probably be out of date, it’ll be totally different. You’ll have a financial institution of vitality that you’ve till the hybrid system [is utilised] and also you’ll be capable of recharge it, it’ll be on on a regular basis. With the push-to-pass, there’s an period of time or an quantity of pushes; we’ve had it a few alternative ways.
“In order that’s what we checked out. We simply gave the drivers 200s – you go make a 20-lap run, use it as you wish to. I feel most used about half on the 20-lap run, so 100sec. It was fascinating to see the way it performed out.”
Frye estimated it might be “January/February subsequent yr” when the two.Four-litre hybrids will probably first hit, and that Friday’s check validated the aero adjustments made throughout testing final fall, as IndyCar seeks to enhance the racing on the Indianapolis 500.
