it's a bit of a disappointment to see that there was much more that they were able to but couldn't because they were limited on time and money. What deadline were they limited by? The car doesn't even race! Why so few test miles? Why not extend the time of development by a few years? The engineers behind it were clearly very passionate and motivated. Imagine a v6 or v8 swap, larger turbos, or the larger tires! Maybe we will never get to see a truly unlimited race car. Maybe that's what the bolide is for.
@@enolopanr9820more time spent working on the car = more wages paid, more facilities being used, all in all, more money being spent. Time really is money, and money is a valid constraint
Seeing this car in action at Rennsport Reunion in 2018 was unbelievable. It clocked 188 mph at the Laguna Seca speedtrap. Anyone who has been there knows the speed trap isn't that far up the main straight. Rocketship does not describe the 919 Evo, and seeing it up close in the paddock was something I will never forget.
Taking a space ship of a race car to laguna seca and only taking 2 seconds off a track record set by an indycar with no power steering from the time of grainy tv footage is mental and a testament to how good some race cars were.
The front diffuser is in fact a nozzle, the opposite to a diffuser. A nozzle accelerates the air and reduces the pressure. (Think of the nozzle at the end of a garden hose, in the hose the water pressure is high and the velocity is slow, at the tip of the nozzle the pressure is atmospheric and the water velocity is much higher than in the hose.) A diffuser slows the air and increases the pressure. The nozzle at the front accelerates the air relative to the car from car velocity to a higher velocity producing high velocity air going under the car with the subsequent drop in pressure. High pressure converted to high velocity and low pressure. The diffuser at the back slows the high velocity air and increases the air pressure back towards atmospheric pressure. High velocity and low pressure converted to lower velocity and higher pressure. Both nozzle and diffuser work together to produce the higher velocity and lower pressure under the vehicle.
I forget what it's called (F-Duct?) but they had a similar concept in F1 for a bit. Sauber came up with it I think, hence they all ran the shark fin bodywork for a while.
7:30 Regarding tyre width, increasing it doesn't increase the grip from friction. The formula for friction forces do not even include information about the contact area. However, wider tires are better for race-cars for two main reasons. Firstly, tyres, especially soft racing tyres, don't get all of their grip from simple surface interaction friction, they get some of their grip by smooshing into the gaps and cracks in the road surface which is HIGHLY dependent on contact area. Secondly, larger tyres experience less pressure because the force from the ground is acting on a larger area. This means they wear more slowly (and there's more tyre to be worn away) which lets you get away with softer compounds that have higher coefficients of friction, while still having a working tyre after a lap.
I would have sworn I learned about that from this channel, in one of his videos on the history of F1 tyres. If so, it's an odd oversight. Maybe he meant more grip over the entirety of a lap - since a smaller patch would get too hot and wear too fast, given it's already a problem with the quite wide F1 22 regs tyres.
iirc the main reason, that applies to all cars, is that the physics equation is perfect world setting only. in reality as cars lose grip on a turn they lose material and for that the wider tyre means losing less % of total material
As a newly retired former Ad Man, and long time automotive fanatic, my life would be complete if I was to win this drive. Love this channel and this episode. ❤️👍🍷
I never used to be into cars, but racing sims got me deep down the rabbit hole. I still don't understand much of it, but I absolutely love the sport and have a huge amount of respect for those involved.
@@moiv8 I play Gran Turismo 7 as my main simulator, and honestly, I've really enjoyed doing oval races. I know they SEEM basic on the surface, but there is so much strategy that goes into those races.
Thanks to this video, I loved the 919 LMP so much that I am building a replica Sim 919LMP fully functional wheel. Insane beast of a car and a wheel with more functions than I will ever need.
The 919 EVO did not break the lap record around Laguna Seca. Earl Bamber said he did a 1:07, but the unofficial outright track record is held by Marc Gene at 1:05.786 in an F2003-GA.
I frigging love the 919 Evo, such a wild project even with the time and budget constraints. Managing to push the carbon tub and tires to their limit just from aero gains is just wild haha.
Like with everything on high performance vehicles, everything needs to work together. So sometimes wheel covers are great pieces of aero, especially when designed properly and in harmony with the rest of the cars aero. But other times they can restrict airflow to or from the breaking systems, which could mean red hot/combusting breaks. Its always something that's a pro vs. con on these cars. I like to assume the best engineers in the world tend to look at every avenue to make their cars faster, so Id bet they probably looked at em and decided to opt out.
@@Amm17ar indeed, it works best for top speed records, which need minimal braking, only when you end the run. For a track car it needs airflow like crazy for the brakes, so that wouldnt work.
Thanks Scott, exellent video. That's an answer for the guys who says "unrestricted car, blah blah". Yes it isn't commited to any rules, but the huge time and money constraints make 919 Evo even more impressive.
Top notch video, good explanation of all the features, although no mention of the driver, takes a top driver, to pilot a car like that, at those speeds👍
19:35- that’s gotta be the ultimate butt-pucker moment for a driver in a predominantly aero car- getting that light over a crest. I watched(YEARS ago), the BMW LMR go ass over tea kettle at road Atlanta on approach to the downhill chicane on the back straight. I can’t remember if it was lhetto or their other guy. We left that race with the front clip of that car. The guy with us that took it passed away a few years later and his wife sold it for pennies because she thought it was “just some broken plastic”. We all know it wasn’t plastic and DEFINITELY not junk. It was a piece of history that was sold in a garage sale for $10. If you’re reading this and have that front clip- shame on you for taking advantage of her. You know what you did
Imagine how much cheaper would F1 cars be if instead of making a 10 million dollar engine, you just evolved the suspension, aerodynamics and reduced weight.
Yes, a $10 million engine that is weaker than engines made decades ago. Modern racing stifles innovation and keeps fair competition from eating their lunch... see Koenigsegg. Lol, he smoked them all.
@@JoeGator23 weaker? define "weak", because right now F1 has the more reliable and efficient engines in the history of sport. Mechanical DNFs due to engine failures are very VERY rare. They may not have the biggest power output, but they compensate it greatly in other areas. Current F1 engines would smoke any of the previous F1 engines.
@@TheProkonoverThat's not true because power and weight are the only relevant engine characteristics. Longevity wouldn't be a concern if it wasn't for ridiculous regulations.
7:31 "tire width doesn't affect grip..." a quackademic says what?! 🤣 24:11 many years ago, the best engineer I studied with (former tire engineer) proposed an active geometry suspension which could give better control over the contact patch
This presentation provides a very condensed and on point picture of the why of engineering - Great subjects and lessons on how to balance competing requirements - Thank you for posting
The takeaway here should be how insanely fast F1 cars are if an LMP1 car needs its fuel flow limit removed, energy deployment limits removed, skirts added, weight reduced, special custom quali tyres fitted and movable aero added just to match F1.
Bingo. If they made a new one every year and raced it against other equally unrestricted cars every weekend all around the world then maybe it would be a more valuable comparison. But I've seen this clickbait title too often now, especially since it was immediately beaten again the very next time F1 went to Spa after this record even though they didn't give a shit about absolute lap records. Nobody is questioning the fact that regulations hold cars back. That's what's impressive with F1 is that it takes a purpose built unrestricted version of the second fastest race car in the world to go faster than they do every weekend.
the thing about wider tyres is that there's more area to dissipate the heat, so they can be a softer compound. Now there is also a little more traction given when there's less weight per square inch too, but that negligible. The crux is the wider the tyre, the softer it can be
@@drd1449 that is also dictated by how soft the tyre is. The narrower the tyre, the hotter it'll get, even overheating, and eventually the quicker it'll ware
@@drd1449 whilst technically true, not really. If you push hard and rub your desk you'll generate more grip, if you lightly touch it and rub your desk, you won't generate nearly as much grip. This is a crude example, but is the same principle. if you double the width, you halve the pressure applied
I wanna see a high-end series with the biggest performance restriction moved out of the car. The driver. Put them in a sim-rig at the track (lots of marketing potential there), the amount of weight saved from all the crash protection and need to have a huge hole in the middle, would allow for much faster cars on current tyre tech. Then mix in WEC Hypercar style rules governing amount of downforce and such, but mix in a limitation on aerodynamic wake in critical areas (so the engineers work to reinforcing that intent, rather than against it). Not having a life on the line when things get pushed too far, would help liberate the regulators as well, so that engineers can really have some fun. Slashing the weight limit from F1's level, would mean existing catch fencing should typically be sufficient to deal with the increased speeds as well. The drivers would still have to be at the track to keep network latency sufficiently low, and guard against DDOS, but they also wouldn't be exposed to the harsh environment inside the cockpit. Sure, it wouldn't be for some, but I'm sure there's a decent audience that could easily grow.
NASA develops state of the art race car with the most advanced technology in history. Conquers every lap record at every well known track. All except Brands Hatch. Record set by a UA-camr still stands.
I know that’s a wink with the last sentence (😉). That’s like saying “UA-camr Ward Carroll” when talking about the F-14 fighter pilot who 'catted’ and ‘trapped’ off of Aircraft Carriers long before he was on UA-cam. 😄
The wider the tire the less shear force the rubber has to deal with because of the larger surface area. Which means less wear and less heat which in turn means you can run much softer compounds without them falling apart. So more grip! If anyone wanted a more detailed explanation.
majority of the “suction” that diffusers produce is a product of lower pressure in the wake of the car. the bernoulli principle works to extract the most benefit from high pressure to low. not really related to airfoils
I would love to see an f1 team do this. Set up their car with no fuel flow limit and max engine power setting and rip it around a circuit to see how much they can obliterate a lap record.
diffusers don't accelerate air, it expands and slows down, but in the middle, where it is constricted it bennefits from a bigger difuser, thus creating more downforce. (*Edition*) Also, low pressure doesn't suck, it simply doesn't match the force of the highpressure when pushing the car up. That's why we call it a pressure difference.
When I watched the 919 lap of the ring, I was gobsmacked that despite the insane time, there were a few spots where the driver was leaving a lot of time on the table (plenty of places he wasn't too), it could go faster with someone who cared less about waking up tomorrow at the controls.
I don't think we can say with certainly where exactly he could've gone faster because we know very little about the car compared to the driver and the engineers.
Driving this car in the simulator with VR is an experience. It's crazy how far it can be pushed around turns that you'd normally crash on going 2/3rds the speed in any other car. I can only dream of actually driving something close to the real thing in real life one day.
FUN FACT: the W11's time around Spa is quicker. They did a side by side comparison and the Mercedes' W11 was quicker through the corners while it held its own on the straights, which is where it made up a lot of the time it lost to the W11 through the twisty bits. F1 cars, well the Mercedes' W11 specifically is still faster.
even SF-71H went faster with sebastian vettel in SPA Q2. Would have gone even faster in Q3 as in that time party mode for Q3 was a thing. Sadly it rained for the last part of qualy.
Id love to see an F1 team do this with a turbo hybrid powered car as they are all under run for longevity and without limits those engines could be monsters.
@@soleenzo893 It's such a thrill the first time you take this car and full send at Schwedenkreuz. Then full send again in Fuchsröhre and uphill braking for Adenauer Forst.
@BattleBro360 No, I play AC on PC and the mod I downloaded has three versions of the X2014 (500, 1700 and 2000+ HP). The first one is kind of like a normal F1 car, the second one is extremely fast, but the most powerful one is just silly haha. It's not even that hard to control and I use a controller. Thing is just planted to the ground.
If that Porsche V4 mill was available as a streetable crate engine for hot rods, kit cars, small trucks, boats, light aircraft, motorbikes and racing applications, I’d probably stick one in a Ford Pop, Corsair, MGTD, a 1927 Model T or Volkswagen Beetle. What would you put yours in?
Great success story of the Porsche 919. Just like with the 917, they rewrote the rules on how to build a car. Repeatedly. Focus on creativity, structural integrity and budget to build the fastest track car they could within a year. More power, more grip, more aerodynamic features, less weight and some other things helped.
One could argue that Thrust SSC was a race car faster than F1, a car with no rules... No regulations that state you must turn left or right to avoid impact with a wall, just drive straight 😂
"Add lightness" to the car. Of course. To make it less slow. And remove smaller grip from the tires by taking out less air. Much less air was taken out! 10 times less vacuum and 5 times less lack of grip. All that increased the off-track time variable of timed time. But since this was no rules racing, high quality, illegal "street" lightness was added, so no weight was removed!
QUESTION: why not a brush system of bristles as a skirt.. it flexes without losing contact and if thick enough will stop unwanted airflow... not an engineer but seems like something to explore for cost effective research .. idk

Excellent insights and video production. Thank you!
Excellent video team, it's great to see what goes on behind the insane Nurburgring lap!
The engineer is so laid back
He's an Aussie.
Will forever be my favourite car its abosluetely incredible
Absolutely love the Brands Hatch plug haha, love your channel and you and your team rock! Keep up the great work🙌⚡️🙌
NASA develops state of the art race car with the most advanced technology in history. Conquers every lap record at every well known track. All except Brands Hatch. Record set by a UA-camr still stands.
I know that’s a wink with the last sentence (😉). That’s like saying “UA-camr Ward Carroll” when talking about the F-14 fighter pilot who 'catted’ and ‘trapped’ off of Aircraft Carriers long before he was on UA-cam. 😄
Congrats to you gor holding brands record. I was at brands the day that porsche went around the track & even got up close to it in the pits
The wider the tire the less shear force the rubber has to deal with because of the larger surface area. Which means less wear and less heat which in turn means you can run much softer compounds without them falling apart. So more grip! If anyone wanted a more detailed explanation.
majority of the “suction” that diffusers produce is a product of lower pressure in the wake of the car. the bernoulli principle works to extract the most benefit from high pressure to low. not really related to airfoils
I would love to see an f1 team do this. Set up their car with no fuel flow limit and max engine power setting and rip it around a circuit to see how much they can obliterate a lap record.
Imagine if F1 technology had been kept secret for the last 30 years, these sports cars would be miles behind.
Love these videos dude. Would like to see your driving more too!
I love how every time he talks about what he did, he has a huge smile! 😁
diffusers don't accelerate air, it expands and slows down, but in the middle, where it is constricted it bennefits from a bigger difuser, thus creating more downforce. (*Edition*) Also, low pressure doesn't suck, it simply doesn't match the force of the highpressure when pushing the car up. That's why we call it a pressure difference.
When I watched the 919 lap of the ring, I was gobsmacked that despite the insane time, there were a few spots where the driver was leaving a lot of time on the table (plenty of places he wasn't too), it could go faster with someone who cared less about waking up tomorrow at the controls.
I don't think we can say with certainly where exactly he could've gone faster because we know very little about the car compared to the driver and the engineers.
True, but there are defo spots where he seems more cautious@@EarthIsFlat456
Driving this car in the simulator with VR is an experience. It's crazy how far it can be pushed around turns that you'd normally crash on going 2/3rds the speed in any other car. I can only dream of actually driving something close to the real thing in real life one day.
I wonder how long it's gonna be until Scott mentions his Brands Hatch lap record once more
What a flex to have a lap record
No rules put up against the 1 most restricted F1 cars in history, do the same test with the Benetton 186 in qualifying trim or a Ferrari 412t2 :D
Not sure oabout the Benetton 186 but in testing trim the 412t2 could hit 394km/h
23:09 ooooh that's what BBW means.
Great examination of the they did it and explanation of why...
FUN FACT: the W11's time around Spa is quicker. They did a side by side comparison and the Mercedes' W11 was quicker through the corners while it held its own on the straights, which is where it made up a lot of the time it lost to the W11 through the twisty bits.
F1 cars, well the Mercedes' W11 specifically is still faster.
even SF-71H went faster with sebastian vettel in SPA Q2. Would have gone even faster in Q3 as in that time party mode for Q3 was a thing. Sadly it rained for the last part of qualy.
Id love to see an F1 team do this with a turbo hybrid powered car as they are all under run for longevity and without limits those engines could be monsters.
This car is absolutely mental to drive in a sim. Especially on Nordschleife.
omg yes, i spent all of lockdown back in 2020+ doing exactly this on asseto corsa, what a blast. love this car
@@soleenzo893 It's such a thrill the first time you take this car and full send at Schwedenkreuz. Then full send again in Fuchsröhre and uphill braking for Adenauer Forst.
Unfortunately the versions used in AC and PC2 are not very accurate as they're only mods made by fans.
@BattleBro360 The 2000+ HP version is comically quick. It's so insane that I did like a 3:30 around Nordschleife and I made tons of mistakes.
@BattleBro360 No, I play AC on PC and the mod I downloaded has three versions of the X2014 (500, 1700 and 2000+ HP). The first one is kind of like a normal F1 car, the second one is extremely fast, but the most powerful one is just silly haha. It's not even that hard to control and I use a controller. Thing is just planted to the ground.
So sad mate that I can’t enter from Australia. Still love your channel. Cheers from Bundaberg.
F1 is the most regulated sport in history. Not hard to imagine something faster. Much, much faster.
great video by the way thank you for the amazing commentary!!!!
What an amazing feat of engineering. Porsche should be very proud of their accomplishments.
HAVE YOU THOUGHT ABOUT A TEACHING RACING BASICS PLAYLIST SERIES?
it would be a cheap easy way to make a video, and make money.. LOVE WHAT YOU DO
the lap set by Yours Trulli?! is he related to Jarno Trulli?
If that Porsche V4 mill was available as a streetable crate engine for hot rods, kit cars, small trucks, boats, light aircraft, motorbikes and racing applications, I’d probably stick one in a Ford Pop, Corsair, MGTD, a 1927 Model T or Volkswagen Beetle. What would you put yours in?
2:09 I regret to inform this but the W07 Hybrid is a 2016 car. The 2017 car is the W08 EQ Power+.
Oh wow, I mean I knew you were a driver and all but hot damn. That's a hot lap, congrats on still holding the lap
i mean, i'd really want to see f1 without any limitation... what kinda beast they could make with such opportunity
Could you imagine going around the green hell in a group c monster? Holy crap that would be insane
At this point it’s just a reverse airplane
That’s why I love them because it goes with the as above so below theory
Great success story of the Porsche 919. Just like with the 917, they rewrote the rules on how to build a car. Repeatedly. Focus on creativity, structural integrity and budget to build the fastest track car they could within a year. More power, more grip, more aerodynamic features, less weight and some other things helped.
The wide tire thing is technically true. As it's just a division of the normal force. However, a wider tire can divide the heat over a greater area.
One could argue that Thrust SSC was a race car faster than F1, a car with no rules... No regulations that state you must turn left or right to avoid impact with a wall, just drive straight 😂
This was very interesting, watched it several times
Awesome from Tasmania 🇦🇺✅
BBW, loads, vas deferens (vast difference), fat bottom Porsches, you make the rockin world go round.
Long live the genius of Jim Hall
I want to see them build a swamp buggy race car, Just think about that for a minute!
Mention it all you want - mad props!!!!
"Add lightness" to the car. Of course. To make it less slow. And remove smaller grip from the tires by taking out less air. Much less air was taken out! 10 times less vacuum and 5 times less lack of grip. All that increased the off-track time variable of timed time. But since this was no rules racing, high quality, illegal "street" lightness was added, so no weight was removed!
All those car to car shots of the 919 on the Nürburgring where filmed by me :)
QUESTION: why not a brush system of bristles as a skirt.. it flexes without losing contact and if thick enough will stop unwanted airflow...
not an engineer but seems like something to explore for cost effective research .. idk
This is one of the best videos you’ve done on a specific vehicle. Thank you. This is awesome.
Another great vid man
So you're telling me the fastest car in the world could have been even faster had time not been an issue??? Perfection is never meant to be, is it? 😳😲
