The NTT IndyCar Collection’ midseason shift to hybrid electrical powertrains is its largest technological change because it launched turbocharged V6 engines in 2012. There’s rather a lot to attempt to perceive within the changeover, so I’ve tried to give you as many questions and solutions as potential to assist in the method.
With upwards of fifty Q&A matters to cowl, we’ll break them right into a multi-part function beginning with a few of the background and fundamentals and comply with with a number of installments that simply is likely to be of use in the event you’re considering IndyCar’s new hybrid route.
WHAT’S THE HISTORY? HOW LONG DID IT TAKE TO GET HERE WITH INDYCAR GOING HYBRID?
The abridged model of the story begins with the announcement about going hybrid being made on Aug. 1, 2019. COVID delivered some big setbacks in 2020 and 2021, and once more in 2022 — usually of the availability chain selection — however the sequence’ unique vendor for the mission additionally dropped the ball, which introduced the initiative again to zero and compelled an entire reboot.
Late in 2022, longstanding IndyCar engine suppliers Chevy and Honda took over the mission to maintain it from failing. To take action, they made huge monetary and personnel investments by rerouting their new 2.4-liter IndyCar engine improvement budgets to fund the mission. And in doing so, they saved the hybridization initiative and received the mission to a spot the place a closely revised vitality restoration system (ERS) idea was testing late in the summertime of 2023.
Some new ERS points emerged in direction of the tip of the 12 months, so the plan to go hybrid at first of the 2024 season was pushed again. Extra testing adopted with a “closing spec” model of the know-how that might enable IndyCar to turn out to be hybrid, and with newfound confidence that all the pieces was heading in the right direction, the sequence declared in Might that it could cross the hybrid threshold in competitors at this weekend’s July 5-7 race at Mid-Ohio.
It should find yourself being an extended gestation interval — 4 years, 11 months, and 6 days — from the mission receiving the general public inexperienced mild to seeing the inexperienced flag wave over the sphere of hybrids on Sunday on the Honda Indy 200, however it’s lastly taking place by way of the resilience, expenditures, and sacrifice of some nice folks and corporations.
SO, WHAT’S THE THING CALLED? DOES IT HAVE A NAME?
IndyCar’s new ERS doesn’t have a customized title. However whereas we have been chatting on the Speedway in Might, IndyCar communications VP Dave Furst nicknamed it “Harry the Hybrid,” which I cherished, in order that’s what I’m going with: Harry the Hybrid.
IT’S ALSO BEING CALLED A “HYBRID SYSTEM” AND A “HYBRID UNIT”?
Sure. There’s the ICE and the ERS, and collectively, they turn out to be a hybrid powertrain, however there’s no such factor as a “hybrid system” or “hybrid unit.” Right here, hybrid simply means two several types of motors working collectively.
Even so, plenty of folks in racing simply check with the entire thing as a “hybrid system” or no matter as a result of it’s simpler than saying “vitality restoration system” or “ERS,” I assume.
So…simply go together with hybrid system or hybrid unit. (And forgive me within the coming days once I surrender and go together with it as effectively.)
THE ERS IS NEW. WHAT ABOUT THE ICE?
Nope. The ERS is certainly brand-new, however the ICE is similar 2.2-liter twin-turbo V6 components IndyCar has saved since 2012.
The ICEs Chevy and Honda simply used within the automobiles on the June 23 race at Laguna Seca are the identical for this weekend in Mid-Ohio and for years to return. Solely the ERS facet is new and being added to the automobiles.
WHO MAKES IT?
If we keep on with the primary objects of curiosity within the package deal, it’s Chevrolet and Ilmor Engineering and Empel chargeable for one half, Honda and Honda Racing Company US and Skeleton and BrightLoop for the opposite, plus Dallara, with IndyCar’s technical staff overseeing all elements of the ERS and setting the hybrid laws.
WHAT ARE THE MAIN COMPONENTS IN THE ERS PACKAGE?
There’s an electrical motor, the motor generator unit — the MGU — that connects to the ICE and the transmission and spins as much as 13,000 rpm. The MGU each costs an vitality financial institution and takes the vitality again and helps to speed up the automobile. It’s made by Empel beneath the route of Chevy and Ilmor.
Its ERS companion is the vitality storage system — the ESS — which receives, holds and returns {the electrical} vitality the MGU makes. HRC US assembles the ESS utilizing 20 supercapacitors provided in every unit by Skeleton.
As a part of the ESS package deal, BrightLoop makes the DC-DC converter, which is a small system that regulates voltage.
The DW12’s pre-existing engine management unit (ECU), the McLaren-TAG 400i that runs the turbo V6s, has additionally been tasked with controlling all elements of how the ERS models operate and carry out.
The final important merchandise within the loop is the steering wheel, which is customized to every driver, and has levers and buttons the drivers use to instruct the ERS to seize vitality or flip that vitality into horsepower and torque.
The MGU is about to present drivers an additional 60 hp and 33.2 lb-ft of torque to go together with the 700-plus hp the ICEs provide. The ESS can maintain a most of 320 kilojoules, which is a measurement of vitality. The ESS is about to have a most output of 60 volts and 2000 amps.

The abridged model of the story begins with the announcement about going hybrid being made on Aug. 1, 2019. COVID delivered some big setbacks in 2020 and 2021, and once more in 2022 — usually of the availability chain selection — however the sequence’ unique vendor for the mission additionally dropped the ball, which introduced the initiative again to zero and compelled an entire reboot.
Late in 2022, longstanding IndyCar engine suppliers Chevy and Honda took over the mission to maintain it from failing. To take action, they made huge monetary and personnel investments by rerouting their new 2.4-liter IndyCar engine improvement budgets to fund the mission. And in doing so, they saved the hybridization initiative and received the mission to a spot the place a closely revised vitality restoration system (ERS) idea was testing late in the summertime of 2023.
Some new ERS points emerged in direction of the tip of the 12 months, so the plan to go hybrid at first of the 2024 season was pushed again. Extra testing adopted with a “closing spec” model of the know-how that might enable IndyCar to turn out to be hybrid, and with newfound confidence that all the pieces was heading in the right direction, the sequence declared in Might that it could cross the hybrid threshold in competitors at this weekend’s July 5-7 race at Mid-Ohio.
It should find yourself being an extended gestation interval — 4 years, 11 months, and 6 days — from the mission receiving the general public inexperienced mild to seeing the inexperienced flag wave over the sphere of hybrids on Sunday on the Honda Indy 200, however it’s lastly taking place by way of the resilience, expenditures, and sacrifice of some nice folks and corporations.
SO, WHAT’S THE THING CALLED? DOES IT HAVE A NAME?
IndyCar’s new ERS doesn’t have a customized title. However whereas we have been chatting on the Speedway in Might, IndyCar communications VP Dave Furst nicknamed it “Harry the Hybrid,” which I cherished, in order that’s what I’m going with: Harry the Hybrid.
IT’S ALSO BEING CALLED A “HYBRID SYSTEM” AND A “HYBRID UNIT”?
Sure. There’s the ICE and the ERS, and collectively, they turn out to be a hybrid powertrain, however there’s no such factor as a “hybrid system” or “hybrid unit.” Right here, hybrid simply means two several types of motors working collectively.
Even so, plenty of folks in racing simply check with the entire thing as a “hybrid system” or no matter as a result of it’s simpler than saying “vitality restoration system” or “ERS,” I assume.
So…simply go together with hybrid system or hybrid unit. (And forgive me within the coming days once I surrender and go together with it as effectively.)
THE ERS IS NEW. WHAT ABOUT THE ICE?
Nope. The ERS is certainly brand-new, however the ICE is similar 2.2-liter twin-turbo V6 components IndyCar has saved since 2012.
The ICEs Chevy and Honda simply used within the automobiles on the June 23 race at Laguna Seca are the identical for this weekend in Mid-Ohio and for years to return. Solely the ERS facet is new and being added to the automobiles.
WHO MAKES IT?
If we keep on with the primary objects of curiosity within the package deal, it’s Chevrolet and Ilmor Engineering and Empel chargeable for one half, Honda and Honda Racing Company US and Skeleton and BrightLoop for the opposite, plus Dallara, with IndyCar’s technical staff overseeing all elements of the ERS and setting the hybrid laws.
WHAT ARE THE MAIN COMPONENTS IN THE ERS PACKAGE?
There’s an electrical motor, the motor generator unit — the MGU — that connects to the ICE and the transmission and spins as much as 13,000 rpm. The MGU each costs an vitality financial institution and takes the vitality again and helps to speed up the automobile. It’s made by Empel beneath the route of Chevy and Ilmor.
Its ERS companion is the vitality storage system — the ESS — which receives, holds and returns {the electrical} vitality the MGU makes. HRC US assembles the ESS utilizing 20 supercapacitors provided in every unit by Skeleton.
As a part of the ESS package deal, BrightLoop makes the DC-DC converter, which is a small system that regulates voltage.
The DW12’s pre-existing engine management unit (ECU), the McLaren-TAG 400i that runs the turbo V6s, has additionally been tasked with controlling all elements of how the ERS models operate and carry out.
The final important merchandise within the loop is the steering wheel, which is customized to every driver, and has levers and buttons the drivers use to instruct the ERS to seize vitality or flip that vitality into horsepower and torque.
The MGU is about to present drivers an additional 60 hp and 33.2 lb-ft of torque to go together with the 700-plus hp the ICEs provide. The ESS can maintain a most of 320 kilojoules, which is a measurement of vitality. The ESS is about to have a most output of 60 volts and 2000 amps.
The NTT IndyCar Collection’ midseason shift to hybrid electrical powertrains is its largest technological change because it launched turbocharged V6 engines in 2012. There’s rather a lot to attempt to perceive within the changeover, so I’ve tried to give you as many questions and solutions as potential to assist in the method.
With upwards of fifty Q&A matters to cowl, we’ll break them right into a multi-part function beginning with a few of the background and fundamentals and comply with with a number of installments that simply is likely to be of use in the event you’re considering IndyCar’s new hybrid route.
