My biggest questions answered. Marshall you had mentioned initially that if a driver had exhausted the capacitors they wouldn't be able to start. Super happy to know they've gated in a reserve charge to still allow for it!
I want to know why capacitors are used over batteries Like a list of advantages to both and then the drawbacks, and then how it can be applied to the regular cars on the road
Well here we go Mid Ohio.... I really hope this thing does well, I'm a bit of a doubter but want to be wrong... 100lbs for 60hp I expect lap times to increase which isn't a good sell. The weight increase is very low so it will not upset the center of gravity might actually improve it. This being offset with the aeroscreen weight reduction is a positive. New strategies and more driver inputs to an already taxing car to drive might separate drivers a bit more. I'm excited but have low expectations. The ability to restart potentially reducing yellows can't be ignored either.
Roughly equivalent to push-to-pass power. 66 pounds more weight. We know the weight requires different tire construction. How badly does this change the power to weight ratio? Or more to the point, how badly will cornering and braking be slowed.
The energy store appears to be made up of 20 individual supercaps, each 5000 farad, that can be charged to 3 volts and drawn down to 1.5 volts. The theoretical total energy above 0 volts is 450 kJ, but that's reduced to the 320 kJ quoted by Salters due to the lower discharge limit of 1.5 volts. Skeleton notes that any of its supercaps should not be drawn down below 50% of rated voltage to ensure reliable operation. A direct conversion can be made from kJ to horsepower-seconds, and 320 kJ equals about 430 hp-sec at 100% efficiency, which is obviously not possible. If the actual capability is 60 hp for 4.5 seconds, the system would likely provide 100 hp for only 2.7 seconds. There's no free lunch--the energy store is the limiting factor. The system is like a big engine with a tiny gas tank that must be constantly refilled for the engine to work.
Dear US Honda Racing, please stay in Indycar. Puh-leeeeeeezzzzzz!😭😭😭
I’m loving this video series. Thanks Honda and Marshall for explaining things so that a simpleton like myself can understand.

Excellent deep dive into the specs. Pretty much all my technical questions have been answered!
Great questions, Marshall!
Perfect, this was always the data I wanted to hear. Very excited to watch these units in action
The car feels very complete now that it can restart
More HP is great, but the big news, they can restart after a stall!!!
Let’s bump those rpms of the engine up.

Great videos Marshall!!

David looks like he's 6'5!
Waiting HP numbers!
60hp now...
But what's the point? All of that Tech, money spent for what? 60 HP? Seriously. I really want to know.

Only 60hp?😮😮 the car will not reac 800hp supposedly?
Full deployment with P2P. So engine makes 700hp, plus P2P another 50hp, plus the hybrid 60hp, so that's a total 810hp full chat.
@@izzdin6228 but thay said that p2p will have less hp and time for use
@@Angelbonilla1982 who said? Because major motorsports news outlets report Indycar maintain P2P alongside hybrid.
They're also limiting there hybrid for reliability. It's been mentioned elsewhere that it can max out at 150hp without any changes.
@danielhenderson8316 OK, I would better increase the HP with the same engine to 900, but it need new chassis!,
And Hinchglieff said more than 820hp!! They would stay at 770hp no more than!! Plus, more weight!,
This will be in addition to the existing P2P system.
But they said the p2p will have less hp and time to use
60hp… weak. Turn it up to 100hp+.
Agreed! But let’s test 60 hp for now just to make sure it doesn’t blow up and holds an entire race…step by step.

It's been mentioned elsewhere the max would be 150hp but there starting at 60 for reliability.
They just want to make it work for now.... Supposedly 120hp down the line.
