Bonus Fact! The pistons have a ceramic coating on the top to prevent hot spots from accumulating and causing detonation at full power.

Pronunciation is not what this video is about.
I was wondering if having the cylinder head intake angle flat would that help make the air tumble more or would it decrease the amount of resistance and make more power?
Running on E85? Wouldn't octane be more important than ethanol content? I know plenty of places that sell 95 RON E85, in fact it's the only E85 I've seen on sale... Isn't the higher horsepower number rather for 98 or even 100 RON regardless of ethanol content?
koenigsegg is like the only car manufacturer that does whatever the hell they wanna do and be very good at executing or producing them. AND still pass emissions at that.
Welcome to an company that only exists to create the very finest of engineering. No marketing crap. No market survying. No profit margin maximization. Barely any comprimise to anything else. Just a bunch of people that want to put the most advanced tech they can come up with inside a car.
@@mycosys which is smart on their part. They can buy Honda engines and spec them out how they want for the car for way less than it'd take to engineer their own. Koenigsegg started with ford base engines in their early cars
bUt ThE dEvEl SiXtEeN HaS fIvE tHoUsAnD hOrSePoWeR Hats off to Koenigsegg for actually creating an amazing engine first with pioneering technology and then bragging about it instead of doing the opposite
@@AnarchistMetalhead From my understanding, three clutches engage any of the 3 gearsets on the first gearshaft, leading to three more on the second one which also has three clutches. 3×3 = 9 different choices of pathing and so you have 9 forward gears. The last clutch is for bypassing the second gearshaft altogether making a reverse gear. There are videos explaining this, and they used the patent for reference. Edit: Embarrassing math corrected.
@@AnarchistMetalhead The reason why you want all those clutches is for the "racing" mode of the gear box where the car shifts itself depending on your current speed, torque, rpm and other factors. The Jesko is the first Koenigsegg car that has been equiped with a gear lever for a few years. You can only shift up or down one gear at a time with it, but it also comes with a second functionality where you push the lever forward twice to engage that "racing" mode. In a traditional dual clutch gearbox, the car can only efficiently shift from 1 -> 2; 2 -> 3; and so forth and verce visa. The 7 clutches allow the car to nearly instantanously shift from any gear into any gear. An example for this would be crusing on a highway. To save fuel, you will want to be at a high gear and run the engine on low rpm. Now imagine you want to take over a truck or any other vehicle in front of you. In that case you want high rpm and torgue so you shift down. If you were cruising at 100 km/h in lets say 7th gear, the car would have to shift down from 7 to 6, then from 6 to 5, from 5 to 4 and so on until you reach whatever gear suits your accelleration-needs the most. With the additional clutches, the car can (almost) instantly shift from 7th into 4th gear. TL;DR The addtional clutches are for faster downshifting
This is quintessential EE. It's the reason I subscribed way back when, and the reason I keep coming back. You continue to be the epitome of high-level engineering explained clearly. Keep it up!
@@darryldixon788 I understand it's a double wishbone setup but I'd love to hear his explanation on how it's more beneficial than a more conventional setup.
I don't know why people dislike these videos. This guy clearly knows his stuff and has invested his time and money into making these wicked videos. Keep making these awesome videos man! Really helps people out👌
Since folks are concerned about pronunciation, here's the reveal of Jesko. "The new megacar will be named... the Koenigsegg "Jess-Ko" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Fq2YRCmUuWo.html Language changes, pronunciation changes, it ain't no big deal. :)
What's great about koenigsegg unlike some other hypercar manufacurers is that they don't just focus on top speed but they bring new innovations with every new model.
Yeah I like it, because it has an objective meaning. Production car with more than 1MW (~1341HP) of power. Supercar and hypercar are subjective terms and it mostly tells you how elitist the car was at the time of its release. Because hypercars specs 40 years ago would barely be supercars today. I don't see a natural step up from mega though. Perhaps 2:1 power to weight ratio could be called something.
Opel, VAG and BMW are using cylinder pressure sensors for years now in high volume production. First generation was an integrated design ob glow plug and CPS. New BMW B57 engines uses a separate CPS with an extra channel in the cylinder head for the sensor.
It's great to see someone else completely geek out about this car as much as I have. Nice of Koenigsegg to do so much research that everyone else is going to borrow eventually.
pumping fresh air into the exhaust for better emissions on cold starts...the secondary air system on my 2002 Buick did that! funny how old technology still makes its way into these hyper cars.
Hello Jason, great video as usual. I have a great question, why the Koenigsegg's camless engine hasn't been released yet in a production vehicle? Do you think that it'll be as revolutionary for ICEs as they claim? Thanks!
@@neilmcmahonWhoops.. corrected it In Dutch, my native language, the plural for video is video's (yes, we use the same word) so it is all a bit confusing sometimes
I get so excited when Koenigsegg release a new car, because I know it means a video of you getting all excited about the insane new technology. Keep em coming!
So this is probably the eighth video of yours I've watched in a row and somehow just now realized I was not subscribed to the channel. That problem is now fixed.
There is beauty in function lol. I like how they mounted it so far back but the point it meets the chassis is way forward and has the leverage from the arm its mounted on
This video is AWESOME!! I’m seriously goober illiterate when it comes to engineering, but I was able to follow everything that you said (except for flat plane crank) and it was super cool. I liked and subscribed. Thanks for this really fun video and the education. Great job. 😎🤘🏼👏🏼
Yep, currently battery technology is the main limiting factor in how "good" current EV/Hybrid vehicles are. Once Hydrogen fuel cell becomes a fully realized technology, EVs will be unstoppable. Of course there are all kinds of factors before we get there (since we are not even close, just scratching the surface of the tech).
What? Where have you been for two years.....the 720s and gt2rs and now the Senna have proved hyprid tech is still not needed or ready! The P1s instant torque is useless when it has no traction to deploy it, the 918 weighed 1700kg and the laferraris hybrid made zero difference to an instant response high revving n/a engine.
Can you make a vids about which part of an Engine can be made of CarbonFiber and which couldn't and why? For example why we cannot made a Crankshaft or Pistons out of CB?
Imo, Free valve is only good for optimal efficiency/torque along the whole rev range, doesn't really increase peak power. For performance engines, a simple vvt optimised for high peak power would suffice. Not to mention the risk of destroying the engine if a solenoid jammed due to computer lag.
Because DI sucks. Theyre not reliable in the long term and the typical reason for its design is to cool the combustion chamber as fuel vaporizes to allow for higher compression. Since E85 allowz for higher compression without needing to cool the air more, they dont need it. Plus the third plenum injector cools the intake air as well so theres plenty of cool enough air. DI is great in theory but terrible in reality. Just not practical. Plus the use of DI injection pumps requires them to run off of the crankshafts rotation and with such high horsepower aim you need a lot of fuel. All that extra fuel needs plenty of time to atomize and if you dump a massive amount in the cylinder directly, it wont be able to atomize properly, in addtion to the pumps needing more power to operate pressures in exdess of 3000 psi and such high flow DI injectors would take up a lot of space in the cylinder. A bigger hole compromises the integrity of the head so with 1600hp, you need one hell of a solid engine.
I really hope big automakers are paying attention to Koenigsegg. These crazy Swedes aren't just sitting there listening to black metal, drinking mead out of horns, and making caveman style supercars. The ideas and technologies these guys come up with are absolutely brilliant, and with Koenigsegg still being a rather small company, their R&D time is light years ahead of the likes of GM, VW,and Ford. These are the people the big guys need to be paying attention to, not the eco mentalists crying for electric everything and the death of all things that anger Green Peace.
Great vid, with good explanations! Don't forget to breathe every now and then though ;) :D I really like the level of explanation, perfectly balanced in between technical and pedagogical. Thats a subscriber more, looking forward to future content!
On regular 93 Octane it makes 1280 Hp. On E85 it makes 1600 hp. The SSC Tuatara makes 1350 hp on 91 Octane, 1430 hp on 93 Octane, and 1750 hp on E85. It's also an emissions legal production engine. Chiron SS 300 makes 1578 Hp on 93 Octane and is an emissions legal production car engine. Obviously the Venom F5 makes even more but the car is not complete so we don't know anything about emissions and homologation etc. The original Venom GT was not homologated, did not undergo emissions testing, and was officially registered as a Lotus by the US govt. I'm not sure why koenigsegg is making this claim. Maybe they were just late and didn't notice the competition. Or they probably knew most people don't fact check before talking.
I watched the Top Gear video on this car. It was okay, but as an engineer, I really appreciate the level of detail that Mr Fenske put in this video. I too probably said "cool" about a thousand times during this video!
@5:55 .. I think the reason why the 3rd injector is that far back is because the other two put out so much fuel they physically block air flow. Australian V8 super cars inject/pour methanol from the top of ITBs.
Great video! Amazing engine. Pressure sensing using Ion sense technology has been around for a long time. Saab started using it in the 90’s. Admittedly this uses the spark plugs and coils to measure cylinder pressure and not an individual pressure sensor.
The Volvo system is called PowerPulse. I remember from when I was a kid, SAAB had a functioning prototype system with a tank that collected cold exhaust gases and recirculated them when the catalytic converter was warm. Didn't go into production, but they had test cars with it on the streets.
The last part, about the pressure sensor. That's how ECU tuners tune ignition timing. So it's like the Koenigsegg Jesko constantly tunes itself. Awesome stuff.
