Thank you for asking the Oval question, that is really going to be interesting to see in usage and hopefully on the broadcast we get some good telemetry information to show it's usage in real time.
This is interesting and solves a different issue than most road car hybrids. The super capacitor is in effect a very short time constant battery for rapid deployment and storage as compared to the LI-ion or NIMH car batteries which charge up to 600V. It is surprising that it operates to 60V. The race system is optimized around frequent hard braking followed by hard acceleration.
I wonder what the actual power output is of those super capacitors. They must be able to output very high current at 60V to generate the required power to operate the motor at around 60hp.
@@shajeezuhair6722Very curious indeed Using online calculations, 60hp would be 44kw. At 60v, that would be an eye popping 733 amps. That seems impossible to race with, would be nice if there was a little more detail on this
@@Rearmostbean I think in an ideal system maybe it's close to that but we would probably have to look into the time constants and discharge characteristics of the capacitor and also look into the actual motors power factor and efficiency if it's running off some inverter (if it's an AC motor). It might not be 60hp constantly, it might change depending on the time constant as well. So you might have a high peak current but then it goes down slowly. It would be cool to look at the actual system because it's quite interesting!
@@shajeezuhair6722 I can't add any real detail except that I believe 60 HP is where they're beginning, but the system is capable of over 100 HP in future.
@@davids9960 That's what I've read from all of the deep dives that Racer has reported on. I'm also wondering how they're going to pair this with the current P2P or if they're going to run the extra boost pressure full time on road courses.
Assuming the supercapacitors are empty, how long does it take to recharge them on track. Simply one hard braking zone? A couple corners? And how long will the ESS hold the charge? All I know is that supercapacitors don't hold charge quite like batteries.
More hand gestures and parts patting would help the explanation. Since most of the road course corners are at 60 to 70 mph they could just use the ICE on the straightaways. Having Auto Stop Start during the pitstops will save fuel. Since the main shaft to gearbox can spin at 12k rpm it will be interesting to how the MGU is meshed in.
Is the rear brake master cylinder now actuated electronically? How is the car compensating for effective brake bias changes mid braking zone because of the MGU?
I found this interesting, even though most of it was over my head. But, I kept wondering when they were going to explain why the super capacitors are covered with aluminum foil? 😆
I’m 68 and took basic electronics in junior college. It would be good to describe what a basic capacitor is as opposed to a chargeable battery. Many millennials would not know what a capacitor is. Then go on to what a super capacitor is.
Questions: is the Voltage Control Device like a wastegate in the past? What would you say is the biggest Innovation? The packaging in terms of size and weight? The supercapacitor?
Are you referring to the DC-DC converter he mentioned that converts 60VDC to 12VDC? If so, it's main purpose is to provide constant 12V to probably around 13.2V DC for all your control components. For example like the controller they mentioned that they program because those specific components only run on 12VDC
@shajeezuhair6722 that prompts another question. Could and should Indycar operate the systems on a 48 v platform like a lot of current street cars with active roll bars, for example. Food for thought, for the new chassis in 2060, maybe.
@@cvillalobos27 I think that might happen due to regulations that may demand a certain voltage for hybrid systems that generates a certain amount of power or something like that but I think the main driving factor for now would be the voltage of the control equipment. For example if they determine they need to run a certain controller or another control device that must run on 24VDC then they would need a 60-24 DC-DC converter. But to your point I can see certain voltage being standardized for certain applications or when you get to a point where your load demand is high I can see them probably switching to a 48V system.
Leave it to IndyCar to actually do hybrid in a sensible manner without changing the noise. That said I imagine Indy will also beat F1 when it comes to dropping hybrid systems in favor of pure synthetic fuels, etc when the time comes.
They're already on renewable fuel several years before F1. I'm also wondering how long until the Bridgestone/Firestone guayule rubber get onto the road.
@@danielhenderson8316 Yes, but that's an ethanol blend. We need 3rd gen full chooch synthetic, like get rid of the turbo and the hybrid, we got enough carbon neutral chaos juice to be loud again. (Although the current engines are also a demonstration on how to be the least vacuum cleaner like)
@@isocuda Can't get rid of the turbo. Turbos are to Indy what V10s should be to F1. The current turbos also gives them room to modify boost pressures for different tracks to avoid another Las Vegas 2011.
Can't afford a new chassis. Can't afford updated bodywork. Can't afford to differentiate cars by appearance or aerodynamics. But the series CAN afford this, that nobody can see? Oh, well.
Politics is everything. Manufacturers like Honda are all going hybrid. Honda basically threatened to leave if something doesn't change. Everyone wants an update on the chassis and aero kit but IndyCar also has to satisfy its engine supplier. Imagine if Honda leaves and only Chevy is left. They've been aiming for a 3rd manufacture for 10 years now it seems. Maybe with the new Fox deal something will change for the better
No one cares about a spec hybrid unit that cost more lap time per weight penalty than is grained on performance. Plus is completely useless on the ovals. WASTE of TIME to fool with it. Ppl talked about it for two races and then it was old hat. Bc newsflash hybrid racing has been around for ten years already… it’s so painfully obvious that it’s a gimmick I think it makes honda look bad as a manufacturer in the series
Utterly invisible to the racing fan. Utterly unnecessary. Unnecessarily costly. Heavier and more complex. Is this REALLY the image Honda wants to portray -- unnecessary cost and complexity for the automobile buyer? And the BEST thing it can do is to have no effect on the quality of the racing. What's next? CVT?
Well now that the rest of the season has gone by I think it’s time to admit how dumb hybrid was. Almost changed the outcome of the championship ruins a good Iowa weekend and now as predicted no one gives a crap.

Hope to see Honda Hybrids in Indycar for many many years to come
I second that. Go Dixon!

Pretty awesome and I really can't wait to see this new tool in the drivers hands and we will see drivers IQ's coming into play
Just looking at this and hearing the details is so exciting.
Great video. Thanks for the education!!
Super awesome

Great report and information, thanks, we appreciate it.

Very good
How long does the discharge last from a full charge?

Volvo has a KERS system that they've been using for at least 10 years, in their road cars...is this tech coming to Honda/Acura road cars?
Fully auto indycar now

It’s all apart of the “great reset” aka new world order.
Exactly, just put a fucking sticker on the car saying hybrid. The people who they’re doing this for won’t notice if it’s mechanically hybrid or not
How is this going to be unnoticed when a racer refires his own car instead of bringing out a full course yellow and a starter motor?
