As an automotive engineer and racing fan this is exactly the type of videos i wanna see, i love it. Very interesting in depth view of the systems. Would be great if you could also provide values in metric units for fans outside of the us.

[@joest23]

I absolutely LOVE the specificity in this video, down to showing model numbers of spec parts. 10/10 video

[@shredofmalarchi]

Awesome video! Nicely done, Pruett.

[@RussellAutosport]

This is phenomenal! Thank you for putting this out there

[@HeyItsAJOmega]

Love this video!! Going into such detail while being so easy to understand. Great work!

[@IvanPandev-rv4bv]

Love seeing the guts of my fav machines like this. Great work MP, and thank you

[@MaunoKoivistoOfficial]

Thank you for going the extra mile, MP! Great video!

[@esc351m]

The content we needed but didn't deserve - this is EXCELLENT

[@DJDouglasWarden]

Absolutely awesome! Very informative. Thank you!!!!!

[@M_IkeLeBlanc]

GREAT video Marshall. 👍👍👍 Thank you!

[@codileger4876]

Thank you sir for the behind the scenes explanation on these. Definitely helps fans understand better these new systems. I’m a little worried as to how much the overall running of the car depends on the hybrid working but it’s part of the process

[@cvillalobos27]

And according to Hinch and Rossi, it will be used in Qualy, but sparsely during the race

[@acft1234]

As usual , Marshall thank you for the incredible analysis !

[@joebarrera334]

Top level content, thanks Marshall!

[@camrsr5463]

is the next chassis going to be Multimatic or Dallara?

[@user-ul7zu6xp5c]

Thanks, MP. Great information.

[@Wafflefrieslmdh]

Common Marshall pruett W😊

[@daviddrewel2719]

Thank you Marshall, the two aspects of racing I love most, engineering and race craft.

[@nickporter574]

Cant wait to see these hybrids in IRL.

[@kevinrafisugiharto5380]

Thank you for the explanation

[@trevormyrus7981]

Excellent video.

[@pablohabibefigueiredo7142]

Are the cars getting any longer? Didi the fuel tank get any smaller?

[@jamesriley9800]

I like that indycar is going this way but when they get a new chassis i hope they go to the GTP engine formula too

[@Tuckpana]

Well Done!!!

[@chrisclodfelter6930]

It will be interesting to see who masters the new hybrid technology the best.

[@shawness93]

Would like to see a new Indy car....been a long time.

[@AdamHinckley]

with GTP hybrids, they were build with hybrids in mind

[@MiguelGLD]

I have no idea what all those pounds and inches are. Otherwise a very interesting look at both systems, clear up a lot!

[@TheOz91]

By the time Indycar commissions a new chassis, axial flux electric motors should be more commonplace. This enables better integration with whatever engine they use, perhaps even replacing the flywheel. There is also a lot of research currently on "zero mass batteries." This does not mean batteries that don't weight anything but rather batteries that form part of the vehicle's structure. The next Indycar can have a battery pack that is a stressed member much like how the engine and drivetrain already are.

[@janremongalura5713]

That's what supposed solid State batteries research articles say. "Very nearly here." Fusion is closer to fruition with the Tokamak reactor being built.

[@danielraymond2409]

Really good loving harry the hybrid 😂

[@djsbadger]

I thought I read the ImSA hybrid is only putting out about 60 hp like the Indy hybrid. Is that actually true.

[@TheRacerChannel]

67hp for IMSA's ERS.

Indycar system (supercap vs battery) is lot lighter and lot more suited for race/sports-car. Battery is for a daily driver

[@charleshulsey3103]

Without new chassis design, they are beating a dead horse 😢

[@cosmostrek2001]

the engine in the acura 2.4 liter was supposed to be the honda engine in indycar but chevy could not build one that worked. how was it going to fit in the indycar.

[@Angelbonilla1982]

Jesus!! There is too much weight for just 60hp!!

[@veloso98]

video is great, indy already with a renewable fuel going hidrid is stupid.

[@alvarohelguero4232]

wtf is an inche!!

[@nitsudocsicnarf347]

Use conversion and the internet to answer your question.

[@jeffreygortz6146]

There is going to be more engine failures due to this hybrid b.s. .......

[@truegret7778]

Well, guess I am reduced to watching NASCAR that still (for now) has raw, brute, ICE horsepower. I think this (hybrid) is the wrong path for IndyCar, and will not be watching or going to the track any longer. Didn't think you could do it, ruin the series, but you did. This looks like nothing more than being a follower (by following F1), rather than a leader. You've lost this long time (since before the days of The Mears Gang) fan.

[@izzdin6228]

Lol NASCAR is also entertaining adding hybrids into the cars to increase power without fiddling with the ICE side of things. Enjoy it while it lasts man.

[@AlistairMaxwell77]

its only 60hp , not going to make any difference . more for show than anything ..... not worth getting upset over . next versions probably not for you though

[@ryanro24]

SOFT

[@truegret7778]

@@AlistairMaxwell77 You've missed my point (and I am not upset, extremely disappointed maybe). I want the raw American muscle car HP, not some slot car e-motor. However, if they used the Koenisegg Quark e-motor I might watch.
