The NTT IndyCar Collection’ midseason shift to hybrid electrical powertrains is its greatest technological change because it launched turbocharged V6 engines in 2012. There’s loads to try to perceive within the changeover that begins this weekend in Mid-Ohio, so I’ve tried to give you as many questions and solutions as doable to assist in the method.
With 65 complete Q&A matters to cowl, we’ve achieved Half 1 on the background fundamentals of the vitality restoration techniques (ERS), and right here, we’re working the remaining — on a variety of topics — in case you’re enthusiastic about IndyCar’s new hybrid route.
WILL THE FOUR TEAMS THAT DID MOST OF THE HYBRID TESTING HAVE AN ADVANTAGE?
They need to. Frankly, it might be a shock (unhealthy pun alert) if Andretti World, Arrow McLaren, Chip Ganassi Racing, and Workforce Penske don’t have a giant benefit over the opposite six groups who’ve achieved minimal hybrid working by comparability.
And to be honest, hybrid or not, these are additionally the 4 groups that win virtually each race, particularly Ganassi and Penske who did greater than anybody, which is why they have been chosen by their respective engine suppliers to deal with every producer’s ERS testing.
WHY DIDN’T THEY SPREAD THE MAJORITY OF TESTING EQUALLY ACROSS ALL 10 TEAMS?
As a result of that wouldn’t have gotten the collection to going hybrid this weekend. The opposite six groups have been introduced into testing as soon as the “closing spec” ERS unit was produced. It wasn’t nice, nevertheless it was by design.

IS THERE ANYTHING ON THE CARS THAT WILL INDICATE WHEN THE ERS UNITS ARE FUNCTIONING?
Nope. For those who’re acquainted with System 1 and its hybrid engines, that collection makes use of the lights on the again of the vehicles to inform drivers and followers when harvesting is being achieved. These lights are instructed to flash. In IndyCar, not less than for the half-season forward, the vehicles gained’t let you know when hybrid working is occurring.
SO HOW WILL WE KNOW WHEN DRIVERS ARE HARVESTING OR DEPLOYING?
Effectively, in case you’re on the monitor and watching the vehicles go by, there’s nothing to warn you to the ERS items being lively. However in case you look away from the vehicles and stare at your telephone or pill, there will probably be notifications out there on the TV broadcasts, and by way of the IndyCar app.
For those who’re watching from house, it needs to be simple to trace. For those who’re trackside, it can require trying away from what’s in entrance of you to know when hybridization is occurring.
And be able to see the utilization alerts on the app or on NBC/USA/Peacock pop up and disappear in a flash. Extra on the why, later.
ARE THE ERS UNITS RELIABLE?
There have been some ERS failures in testing with the final-spec items, however they’ve usually been right down to consumer error. There’s a brand new and extra advanced course of concerned with beginning the vehicles the place the ERS should be set to a sure state earlier than the MGU is supposed to be spun. If, for instance, a group needs to plug the exterior starter in and bump the ICE a couple of times with the ignition off to test one thing, they will’t neglect to undergo the method to get up and prepared the ERS as a result of rotating the MGU with out waking it up — it’s on the identical shaft that spins the ICE — will break the MGU.
And if that occurs, the automotive must be break up in the back of the ICE and the spec bellhousing/ERS unit must be modified. FWIW, it’s already occurred.
However exterior of that, the brand new ERS items have achieved greater than 20,000 laps and over 32,000 miles of testing, and most of it has been optimistic. Utilizing current historical past as a information, there’s a purpose to have optimism for what’s about to occur over 80 laps on Sunday.

CAN DRIVERS USE THE ENERGY RECOVERY SYSTEM TO START THEIR CARS?
Sure. Will they? Solely on uncommon events.
A driver’s capability to make use of the ERS to fireplace the inner combustion engines (ICE) is barely out there when one thing unhealthy has occurred out on the circuit, like spinning and stalling.
SO DRIVERS CAN START THEIR CARS, BUT IT’S LIMITED TO WHEN THEY’RE ON TRACK?
Appropriate. For those who’ve seen and beloved the sights and sounds of IMSA’s hybrid GTP vehicles pulling away from their pit packing containers on full EV energy for a number of seconds earlier than firing up the ICE to take them the remainder of the way in which out…that gained’t be occurring right here.
IndyCar has opted to introduce hybridization in a means that locations a decrease utilization of the system throughout the half-season forward. Particularly, the collection needs to put as little pressure on the MGUs as doable after they aren’t getting used on monitor, and as such, you’ll see mechanics proceed to plug in exterior starters and fireplace the engines on pit lane and on the beginning grid simply as they’ve for many years.
The daybreak of IndyCar’s hybrid period will certainly start with crew members manually beginning the vehicles Friday afternoon…which is attention-grabbing.
As properly, self-starting whereas practising, qualifying, or racing, is proscribed to highway and road programs. Self-starting will probably be disabled by the collection on the ovals.
IF THEY CAN’T LEAVE THE BOX ON EV POWER, WILL DRIVERS USE THE ERS UNITS ELSEWHERE ON PIT LANE?
No, they won’t.
Drivers gained’t be allowed to enter into pit lane on ERS energy, do an EV burnout and launch from their pit field, or use ERS energy after they’ve left the field, nor will drivers be allowed to reap vitality whereas on pit lane. In easy phrases, from pit-in to pit-out, IndyCar’s ERS items will probably be unavailable to be used.
The collection will handle this by sending alerts to the vehicles from race management, utilizing the identical MyLaps communications system that it makes use of to show push-to-pass on and off, that tells the identical McLaren-TAG 400i engine management unit (ECU) to disable the ERS unit when vehicles cross the pit-in timing loop, then to allow the ERS when vehicles cross the pit-out timing loop.
