No, I'm not British, I just put the period on the outside because it makes more logical sense since I'm not borrowing the period, that technically counts as deficit liability, liability meaning who or what is responsible for something.

Might my eyes not deceive me?
gotta be honest, normally don't care about this kind of thing but the exhaust question got me, the presentation and quality of video/narration, kept me. good job random RUclips gearhead guy lol
That reminds me when I was looking at the 19' STI and the dealer didn't know that the spoiler adds 5mph to top speed as well as improves handling. Then he said "I always just pitch the spoiler as a picnic table. It's tall enough it's the perfect height to set food and drink on if you sit on the trunk". I was sold instantly.

The new explanation style without the whiteboard is a huge plus. Gives us great footage of the car with your fantastic descriptions. Keep up the excellent work !!
Ive also heard that due to the immense heat + the fuel continually burning even after its left the headers that the hot air then travelling over the massive rear wing provides additional downforce on top of the downforce provided by the headers simply being turned up and back. would this be a correct theory? maybe a good EE video?

Vinícius actually I don’t think it’s that simple as you made it seem. I drove the latest Corolla in the USA and well the ride was perfect, interior was luxurious, quiet, and very modern but what I didn’t like is the sound system sounded horrible, power seemed lethargic, and the infotainment screen was ugly and big. It’s a mixed bag. Hopefully Toyota makes improvements
Vinícius I wonder why the issues with Honda and what models?? I drove a Cruze and really wanted it because it had everything I wanted but the way the clutch felt on engagement bothered me. I took the Honda Civic 2017 instead but I regret it. It is much louder and the seats do not adjust as well as Cruze. The Cruze will even fit you if you are 1m 90cm tall. I think Cruze was designed in Europe and then assembled in various plants around the world huh? The first gen had oil feed issues for the turbo but newest is ok there.
It could actually generate much more downforce if the exhaust were pointed directly below the rear wing. Since hot gases come out of the exhaust (low pressure air), this would greater the difference in pressure between the top of the wing (high pressure) and the bottom (low pressure), and thus causing the air at the top to "try to" go to the bottom with increased "efforts" (pushing down). Furthermore, if the exhaust pointing below the rear wing were also positioned further away from the center of the car (near the wing tips), it may generate even more downforce. Though, I'm not so sure about this one since the "more freely" flowing air would disipate the heat quicker than the turbulent air at the center of the wing. I'm a student on aviation and this is the first time I'm analysing the aerodynamics of a car, so let me know if I'm wrong.
Hello Mati N, im not an engineer so my comment might not be that precise however i think its not the best idea to put exhausts right below the wing for one reason: it spits flames sometimes. Let me know if you think im wrong, im open to discussion. Have a nice day
@@FiliptheSon Greetings. That's something interesting I didn't thought about, actually. Maybe that is one of the reasons why the center of the rear wing is made of carbon fiber. Now that I think about it, the exhaust shown on the video could not actually be in any better position!! Thanks for your comment!
Is it possible to use exhaust gases to increase down force? blowing them to the wing in an angle that produces down force... my engineering gut says since the car (exhaust, engine, wing and etc) can be considered as 1 system, those forces act as internal forces and cancel each other, but I'm really curious to know the right answer.
Yes, it's possible, and in top fuel it's actually the case, but not from blowing a wing, simply from the force exiting the exhaust pipes pushing the car down. With the 600LT, as discussed in the video it won't have much effect on downforce.
It is also possible when used on diffusers. It's called a blown diffuser which has the excuse blowing hot and high flowing air through the diffuser in F1 cars (not in use anymore due to regulation). The hot and fast moving exhaust causes lower pressure under the diffuser which is the point of the diffuser in the first place, this effectively places the exhaust in a beneficial position as well as increasing down force with no negative drag effects.
Also I would have thought that when under hard acceleration the turbulent air from the exhaust would decrease down force and therefore decrease drag, but when decelerating into corners the effect would diminish, so it acts almost like a DRS system?
@@jethrofennell considering the downforce there wasnt very high to begin with, then the drag wasnt big to begin with. And in this case, turbulent air reducing downforce doesnt always = less drag, since turbulent air can sometimes be the reason for drag behind the car, sucking it backwards
Hey Jason! Thank you for the great content that you post all the time. I would be very interest in getting your take on the auto Start/Stop engine function found in most modern cars today. Is it good, or is it actually bad? Your input would be highly appreciated!
I'd be interested to see if they're getting more down force on the rear axle in higher RPMs in addition to the benefits you discussed, since the exhaust flow is going to be directed upwards. There's an interesting momentum balance problem there.
So, can I say side mounting would be more beneficial than top and rear mount? > Maybe it would save more 7to8 kgs than top mount > Maybe increase 4kgs more if cooling fans are used but still 2 to 1 kgs less than the overall exhaust system for top mount > It won't interfere with diffusers > Also it wont affect the spoilers even by little > And no need to worry about rain
An added benefit of the exhaust venting where it does, is that the turbulent air coming over the roof will dissipate the heat from the exhaust faster, making you harder to hit with heat-seeking missiles!
@@kayceenolasco4439 sesto elemento don't have top mounted exhausts. Lol there cooling holes. If you look closely there are triangle exhausts on the back
You pointed out the advantages, but not the disadvantages. If a top-mounted exhaust is go great, why doesn't every car have one? Or even every mid engine car? Are you saying that the McLaren engineers were the first to think of this? Or did they have to come up with some other clever bit of engineering that enabled a top-mount exhaust?
@@drewmandan Probably because they look funny. When it comes to supercars, it sounds rather vain but looks matter /a lot/, and I think a lot of people love seeing like a quad-tailpipe. Not saying a top-mounted exhaust doesn't look /good/, but it obviously looks different and stands out.
Interesting information on aero for the rear wing. This explains why some cars have a split rear wing and are still able to generate a lot of down force.
The exhaust gasses are too turbulent. And the exhaust pushed the laminar flow away from the car, more simply put: it pushes the airflow that passes the car away from the spoiler. So it gets spoiled. The middle of the spoiler is just there for looks.
DC: the exhaust gas is hot and thus less dense. If we assume that the hot exhaust gas displaces ambient air (turbulent or laminar in flow, doesn't matter) on a 1:1 basis, then the centre part of the wing will produce significantly less downforce with exhaust gas flowing over it than air at ambient temperature would. As noted in the video, the centre section of the wing on most sports (and many racing) cars produce comparatively little downforce given their penalty in weight and drag, so it's less of an issue than if the exhaust were exitting in front of the side panels of the rear wing. Also on this car, a significant amount of downforce is gained by moving the exhaust as the diffuser/ground effect at the back can be both deeper and run the full width of the car... so while the rear wing may be slightly less efficient in this design, the gains in other areas more than compensate for the loss of rear wing efficiency. As the host notes, this design also saves something like 20 kilos (shorter exhaust, no need for exhaust cooling fans in rear panels etc).
It'll be interesting to see if more manufacturers would implement something like this in this in their sedans and roadsters. It might save on manufacturing costs.
for the track it's ok But not for the street. Can you imagine driving a bicycle, or scooter, behind this vehicle that spits the exhaust like literally in your face?
Two big ones I can think of automatically: 1: you're not fighting against physics, I.E., exhaust likes to rise and having exhaust pipes that are lower than the manifold requires more energy to get that out of the system of the vehicle 2: cheaper. Less pipe needed, less physical material costs. Problem is it only really works in a car with a rear engine rather than a front one. After finishing the video: Was right on one, half right on the other. Cool.
Wow, they addressed all the concerns from when I scoffed at a first glance. Can't judge this one by its cover. Good work, engineers. too bad it's not something easily put into use on a sleeper; I'd rather avoid attention, tickets, theft, and high insurance with a souped up rust bucket that won't be as big a financial hit when it eventually gets totalled, thanks.
I miss your car reviews. They were some of the best car reviews on RUclips, and you haven't done one in two years. Not to knock what you HAVE done, but I miss your car reviews.
I didn't quite understand when you explained about the sides of the wing providing the bulk of the total wing downforce. I did understand that but then you said that's why you'll see many cars where the wings dont expand the whole width of the car. Isn't that contradictory since the sides provide more downforce, so having a shorter wing means having less effective area for downforce? Great video!

I'd be interested to see if they're getting more down force on the rear axle in higher RPMs in addition to the benefits you discussed, since the exhaust flow is going to be directed upwards. There's an interesting momentum balance problem there.
Why it's genius? Because it looks awesome. This whole car is pure beauty :D
@Ungregistered User When that happens I usually don't notice her at first glance.. xD
Porsche had that first on the 918- genius on them
Porsche did first top exhaust but it was straight, meanwhile McLarne did some upper direction and that’s the genius engineering.
That finger pointing is kinda hot
Clicked for the exhaust, stayed for the finger pointing.
@@EngineeringExplained yup, definitely!
Jason=daddy
he pointed right to my heart :')
That comment shines a whole new light on your profile pic...
Interesting to see how many things are changed simply be changing the position of the exhaust. Great video!
McLaren's are pure car porn.
I could feel my heart fluttering.
I could watch McLaren videos every day.
So, can I say side mounting would be more beneficial than top and rear mount?
> Maybe it would save more 7to8 kgs than top mount
> Maybe increase 4kgs more if cooling fans are used but still 2 to 1 kgs less than the overall exhaust system for top mount
> It won't interfere with diffusers
> Also it wont affect the spoilers even by little
> And no need to worry about rain

Good catch! In his natural habitat, too!
Would definitely like you to explain how manufactures achieve those crackle and pops for the exhaust.
Very cool, they definitely gave that system a lot of consideration!
An added benefit of the exhaust venting where it does, is that the turbulent air coming over the roof will dissipate the heat from the exhaust faster, making you harder to hit with heat-seeking missiles!
Porsche 918: *_"Am I a Joke to you?!"_*
2011 Lambo Sesto Elemento to both McLaren and Porsche: Am I a joke to you??
@@kayceenolasco4439 sesto elemento don't have top mounted exhausts. Lol there cooling holes. If you look closely there are triangle exhausts on the back
@@youraveragechannel9825 sesto elemento has top mount exhaust behind the rear wing
Excellent wind tunnel turbulence special effects!
You pointed out the advantages, but not the disadvantages. If a top-mounted exhaust is go great, why doesn't every car have one? Or even every mid engine car? Are you saying that the McLaren engineers were the first to think of this? Or did they have to come up with some other clever bit of engineering that enabled a top-mount exhaust?
@@MrCrackbear What's so different about the position of the engine? Isn't it just a mid engine?
@@drewmandan The majority of cars in existence aren't mid-engined!
@@JohnDoe-ne2qs But lots of supercars are. Again, my question is, why don't all mid-engined cars have a top exhaust?
@@drewmandan Probably because they look funny. When it comes to supercars, it sounds rather vain but looks matter /a lot/, and I think a lot of people love seeing like a quad-tailpipe.
Not saying a top-mounted exhaust doesn't look /good/, but it obviously looks different and stands out.
Interesting information on aero for the rear wing. This explains why some cars have a split rear wing and are still able to generate a lot of down force.
The 918 spyder did the same thing too.
xXITZrawXx17 The Porsche exhaust faces backwards tho, not upwards
You forgot the best part of the top mounted exhaust… it shoots flames!🔥
Alright, you've convinced me, I'll buy the LT600
Though it would charge the air over the spoiler creating more negative pressure and more downforce. Another good video.
Wouldnt the top mounted exhaust increase a bit of downforce because exhaust is still air and its traveling over the wing?
The exhaust gasses are too turbulent. And the exhaust pushed the laminar flow away from the car, more simply put: it pushes the airflow that passes the car away from the spoiler.
So it gets spoiled. The middle of the spoiler is just there for looks.
DC: the exhaust gas is hot and thus less dense. If we assume that the hot exhaust gas displaces ambient air (turbulent or laminar in flow, doesn't matter) on a 1:1 basis, then the centre part of the wing will produce significantly less downforce with exhaust gas flowing over it than air at ambient temperature would.
As noted in the video, the centre section of the wing on most sports (and many racing) cars produce comparatively little downforce given their penalty in weight and drag, so it's less of an issue than if the exhaust were exitting in front of the side panels of the rear wing.
Also on this car, a significant amount of downforce is gained by moving the exhaust as the diffuser/ground effect at the back can be both deeper and run the full width of the car... so while the rear wing may be slightly less efficient in this design, the gains in other areas more than compensate for the loss of rear wing efficiency.
As the host notes, this design also saves something like 20 kilos (shorter exhaust, no need for exhaust cooling fans in rear panels etc).
That lime green McLaren looks so god damn beautiful. Work of art.
Answered every question i had. Thank you
Love it, thanks for watching!
Thanks for this exhaustive video.
It was informative, yet short, not exhausting the audience.
I'm just going to leave this here for yall........

Wait, what?
Love that in the preview the caption says “music” as you’re bouncing off the rev limiter
At my house, they would fill up with pine needles and bird poop.
Should’ve let your 600LT chill inside with you on the couch then, like a decent human being
People rich enough to own a car like this don’t let it sit outside.
Can't carry much firewood anyways
Dope video, saw the 600LT at Goodwood last year and fell in love with the top mounted exhausts. Now I know the benefits. Thanks
Where can I find the eBay kit for my Civic?
Incredibly informational as always.
So it's the same concept Porsche used for the 918, huh?!
It'll be interesting to see if more manufacturers would implement something like this in this in their sedans and roadsters. It might save on manufacturing costs.
Time to start my 30 year budget plan
I appreciate the knowledge you bring to this, but don't forget the driving impressions. I know all of the other yahoos do them, but you do them well.
This archaic tech is going to have a helluva time keeping up with the Tesla Roadster 2.0
Liking the finger turbulence effect in the video!
for the track it's ok
But not for the street.
Can you imagine driving a bicycle, or scooter, behind this vehicle that spits the exhaust like literally in your face?
Do you think that the exhaust is like liquid or similiar?
@@miniMEGA29 while exhaust gas is not a liquid like water its still a fluid
Two big ones I can think of automatically:
1: you're not fighting against physics, I.E., exhaust likes to rise and having exhaust pipes that are lower than the manifold requires more energy to get that out of the system of the vehicle
2: cheaper. Less pipe needed, less physical material costs.
Problem is it only really works in a car with a rear engine rather than a front one.
After finishing the video:
Was right on one, half right on the other. Cool.
Nice Nissan
@Ungregistered User because this engine is or7gnally used in a Nissan le mans car back in the 90s
Well all of Mclaren’s new road cars use the same engine and that engine is based off a Nissan race engine from the 80’s
What a ridiculously awesome car. I do really like the 720 as well. Great video.
The amount of comments saying that porsche had this a long time ago is amazing lmao
Wow, they addressed all the concerns from when I scoffed at a first glance. Can't judge this one by its cover. Good work, engineers. too bad it's not something easily put into use on a sleeper; I'd rather avoid attention, tickets, theft, and high insurance with a souped up rust bucket that won't be as big a financial hit when it eventually gets totalled, thanks.
Rename the video: Why Porsche’s idea is better than mclaren’s
I miss your car reviews. They were some of the best car reviews on RUclips, and you haven't done one in two years. Not to knock what you HAVE done, but I miss your car reviews.
Blah Blah Blah...all this engineering talk is exhausting.....nothing but a bunch of hot air. Trust me, I'm a Breatharian.
Ill show you out
Make a video explaining how an after market exhaust improves the performance please
Porsche did it before tho with the 918
Oscar_khw Backward. Not upward.
The slits for water to exit also can let cool air enter that stream of exhaust, so the temps at the end are not so high.
Its as if they learned somethng from the porsche 918.
I didn't quite understand when you explained about the sides of the wing providing the bulk of the total wing downforce. I did understand that but then you said that's why you'll see many cars where the wings dont expand the whole width of the car. Isn't that contradictory since the sides provide more downforce, so having a shorter wing means having less effective area for downforce?
Great video!
