I understand the water fording depth was a joke, but I'm not going to let that stop me from commenting with some factual information. As the owner of a 1963 Amphicar, I can confirm that the front is likely to lift up if traveling through water at more than about 4 mph. BUT, the at the same time, the back will squat, maintaining traction on the rear wheels in somewhat deeper water. The front goes up and the back goes down basically because the car is trying to climb the face of it's own bow wave. Anyway, even with the front tires off the lake bottom, they can provide some steering. The Amphicar is steered in the water with only it's front wheels/tires (it does not have rudders). I suspect the disk brakes, if not the tires and wheels, on the McLaren would be enough to steer it a little even if the front tires lose contact with the lake bottom. So the lifting of the front end is not enough, on its own, to stop it when fording. The question remains, how deep can it ford? I demand a test to find out. :)
In all seriousness though, most of the time whenever I see any SUV (even if it's not supposed to be used for off roading) and sometimes when I see a sedan I wonder what it's off-road capabilities r 😅. For some reason I imagine muscle cars are just more off-road worthy supercars
I just watched a 10 year old video of you explaining how carburetors work and wanted to see if you were still making videos. I was doubtful but glad to see you are.
"Sir you were going 200mph in a 70mph zone, you better have a good explanation" "Yes officer you see, my car has this roof scoop and the faster I go the less resistance the turbo needs to work because of the ramming effect of the intake so I'm speeding to make my car more efficient."
It really, really did! I had the car for one day, so, not a lot of options. I did realize later in the day that if I kept driving up the road, eventually it popped out of the clouds, but I was a little late on discovering this.
That Y shaped intake to keep the rear window view reminds me of a fireplace in a house I stayed at in France. There was a window directly above the fireplace with flues either side. It took me a while to realise why a window over a fireplace seemed strange.
Wow, the reason for that they raised air intake from the roof it's exactly the same as in jet fighters. To keep it out from turbulent boundary layer which decreases efficency of jet engine at high speeds.
You say thanks for watching, but we say.. thanks for the amazing content 'Yayson' 💯 edit: For those who don't know, this is a reference to his Jesko video 😂😂😂
The weather reminds me of when I was working in San Bernadino when I bought my BRZ, went up in the mountains for fun a photos that weekend, instead got fog and rain. Did make for some good photos though
I'm sorry the weather was less than ideal for driving this beaty, but at least you didn't have to deal with a downpour. Thank you for your review of some key attributes. I found this very interesting.
Anyone who has driven a 4x4 with a snorkel on the driver's side will already know what sounds he is talking about. 🤣🤣 Brilliant video, great depth and very informational. I always find myself coming back here.
Good video!! The inlet is elevated to create flow separation between -- which could also be achieved by drilling a series of holes into the point before the intake in a staggered pattern - skipping the need for an inlet diverter and using an inlet bleed instead or bypass duct. If weight is a concern, go with a bunped inlet. The reason you do this is because turbulent air when entering a system creates pockets of inconsistent compression which are bad for combustion. This is actually an aircraft engineering principle! Cars are also often curved because it forms what's called an inverted lifting-body -- that the body shape itself generates downforce via the natural pressure differential of the floor to the roof -- though you often need rear diffusers toward the back (seen as splitter-plates or fins) or ground-effect (which hovercrafts fake to produce lift) becomes a problem and you risk forming a skirt-pocket of air that lifts the car off the road. This is why in high performance cars, the floor of the vehicle's shape is very important!
Funny you ask! I have a video on how that exact transmission works! (I'm assuming it's the same one used in the Veloster N). Here's the whiteboard breakdown! ua-cam.com/video/oQQ3nfIf6EE/v-deo.html
Please make a video about Euro5 för MC. What do manufakturer have to do to make Euro5? They use the same engine but have made some chenges to the mapping it seams.... I dont know. Please look it up and make a video. Love your work Anders
Would the top mount exhaust help w/ fording as you'd have less backpressure? Also, you'd think the flat bottom and diffuser with higher viscosity would cause even more downforce
Hi Jason, isnt this design giving the engine a colder intake vs the side mounted intake? It most definately is colder than a regular front bumper grille, but im curious about the intake temperatures in these two scenarios as the air is technically going through the interior of the car.
Thank you very much for this interesting video. Your thoughts will much appreciated regarding Toyotas newly announcement of hydrogen combustion engines, despite your old video showing its ill effects.
Will you do a video about the experience of driving a street-legal race car (with street-legal racing tires) in the wet? Is it just VSC constantly kicking in at the slightest application of the throttle?
11:24 Jason: *_"when was the last time you was in a vehicle that didn't even have 1 single cupholder?"_* Me: *_"Just minutes before watching the video as a matter of fact."_*
Jason, Hello and welcome to LA. You’re in my backyard. I’m guessing you’re up on CA-2 up in the Angeles Forrest. Confirmed your driving on CA-2 Angeles Crest Highway. One of my favorite motorcycle routes. Did you make it up to Newcombs Ranch?
This sort of confirms a notion I had for decades, that some engines produce more noise from the air intake than from the exhaust. Did you say, BTW, that the air intake doubles as a roll cage?
Also, wasn’t the top-mounted exhaust on the green car contributing to the rear wing downforce, particularly at low speeds, kinda like the 2010s Red Bull with the blown diffuser?
So I wonder why they didn’t use the NACA duct? A lot of research went into extracting air from the stream while adding as little drag as possible. I guess it would have intruded in the cabin too much?
So what does this car use the vents in the doors for? Radiators only? Also, what would the vent in the cheaper cars be on the passenger side behind the B-pillar.
I do have a question. How does the vehicle handle leaves and bugs and other debris that enters the air scoop? Is there a receptacle that the owner can empty on his own? Or is it emptied when the car gets serviced?
I just clicked to get the scoop.. And now I can show myself out... Thank you
Take my like and see yourself out.
I can’t afford the scoop!
Lol
@@jimi7170 I already tipped my waiter. :)
Now I want some Ice Cream.
Thanks for answering the IMPORTANT question about water fording depth. Jeep owners everywhere were curious.
Us Brits would like to know if it's capable towing a caravan...

This thing accelerates faster to 124mph than either of my cars to 60mph. That's insanity.
My Crosstrek is still at the stoplight, dumbfounded by the speed!
My mazda3 would just stall watching this car accelerates from a stop.
My Geo metro is shaking in the garage!
Dude, this car accelerats faster than most of sports bikes 😶😶
Stop driving it on the rain 🤣
Thanks for the very instructive video 😁👌
And there are cars that are far quicker like a 765LT.
I just watched a 10 year old video of you explaining how carburetors work and wanted to see if you were still making videos. I was doubtful but glad to see you are.
okay?
okay?
worth a sub tbh, fantastically informative channel.
Not only is he smart ( very) but he explains things so clearly that even a person vaguely familiar with these things can understand
At first I thought you went to the UK to test it. That can't be LA...
It was a weird week last week
It's sunny here where I am today in the U.K. We have had an amazing spring. Dusty trails for mountain biking.
That’s the LA crest Highway
Wrong side of the road for the UK.
For added performance, you can activate water vapor injection by turning on the window washer
Good to know to raise my McLaren 620R when I need to ford some deep water
Indeed.
"Sir you were going 200mph in a 70mph zone, you better have a good explanation"
"Yes officer you see, my car has this roof scoop and the faster I go the less resistance the turbo needs to work because of the ramming effect of the intake so I'm speeding to make my car more efficient."
Brought to you by valvoline. I use valvoline on my roof scoops
That's what makes them a slick feature.
As a dad, I couldn't resist.
Thanks Rob dahm
I read vaseline at first. I thought you were beating your meat in your McLaren
Just a little tip,
Use the old stuff it'll make your car lighter with time👍🏻
The weather really wanted to ruin your vids 😂
It really, really did! I had the car for one day, so, not a lot of options. I did realize later in the day that if I kept driving up the road, eventually it popped out of the clouds, but I was a little late on discovering this.
@@EngineeringExplained The vid was still great tho
It's sunny as hell today I'm thinking this was the weekend.
I was caught off guard by that start up. Was not expecting that roar. 😳😍
Damn. Driving a $300K car and not being able to see more than 50 feet in front of you because of fog.
Lol the only rainy day for the past 2-3 months in California 😂
That Y shaped intake to keep the rear window view reminds me of a fireplace in a house I stayed at in France. There was a window directly above the fireplace with flues either side. It took me a while to realise why a window over a fireplace seemed strange.
Please tell us more
Excellent review, as usual. We have so many extraordinary cars - truly the Golden Age. Thank you!
I've always wondered about raised roof scoops and why, i can cross that off my automotive question bucket list. Thanks. OMG the sound it makes
Congrats, man. When I found your channel you were demoing a Nissan Leaf.
At this point, I'm just watching these videos just to see Jason's genuine reaction when driving these supercars.
My heart drops a little seeing that interior at 2:47
Mine dropped because of how filthy it had gotten and the rain getting on that alcantara, etc. :(
@@ImUrOBGYN same reason here
You earned the respect of the McLaren engineers that the chief one will talk with you about the car for ages. Cool.
The constant dragging of your fingers across the car is driving me crazy! lol ;)
Dude, me too. Unnecessary.
You ever consider doing a video on a RotaxMax motor? Or a kart frame and some of the weirdness that goes on with those? Love this one!
Wow, the reason for that they raised air intake from the roof it's exactly the same as in jet fighters. To keep it out from turbulent boundary layer which decreases efficency of jet engine at high speeds.
You are a true professional making such an interesting video in challenging (for that car) conditions. I learned a ton as usual.
Liked this type of video from you! Love getting a bit technical on a car that isn’t covered by many content creators :)
Jason, you're able to create interest for things I didn't care about before. You're amazing
Best video in a while. Keep up the good work.
Always the best engineering automotive channel!!
Absolutely brilliant vid dude - informative and well presented - sorry about the weather but that was out of my control :(
That sound in the cockpit is entrancing. Alas, this is as close as I will ever get to owing one, so I enjoy Jason's overview.
Love pieces of engineering like this man
Always wanted to know why roof scoops are elevated in some cars. But why do some of them not elevate the scoop? Are there advantages to that?
More aerodynamic, less impact on drag if it's mounted lower.
@@EngineeringExplained that's what I thought and why I always preferred the low ones like the Saleen S7. Thanks .
You say thanks for watching, but we say.. thanks for the amazing content 'Yayson' 💯
edit: For those who don't know, this is a reference to his Jesko video 😂😂😂
Great preview. Glad you approached the video with its intention in mind, it's a racing car! It can't be reviewed as a road car like it's a 570S.
The weather reminds me of when I was working in San Bernadino when I bought my BRZ, went up in the mountains for fun a photos that weekend, instead got fog and rain. Did make for some good photos though
I just bought a BRZ last week and I'd kill to be driving it in San Bernardino rain or shine! I'm in NYC lol
Can you both tell us more please? I'm on the edge of my seat
You have come a long way Jason. Great to see all your hard work and intelligence paying off 👍. Maybe treat yourself to one,part ex the MX5 (Miata)!
I've been around since just whiteboard videos
Congratulations
@@ehmjauhh5495 Haha I know right, what a goof

And , what with that?
Aaahhh...my favorite grandpa on youtube is back.
My FC RX7 has no cup holder lmao

Cool video, appreciated.
The roof scoop reminds me of the scoop from the Lockheed L-1011 TriStar.
I look forward to how they apply electrification to their designs.
Regenerative... *Suspension!*
So final question, this or the GT3 u drove(or reviewed) last week?
New stuff , thank you

The snorkel! I love it!
Cant wait for your take on a Lotus with roof scoop.

Nobody cares. Exhibit A is the lack of likes for this comment
Lol northern weather is trolling you in LA Jason XD
Awesome innovation in automobile technology.. simple but effective. Enginuity efficiency at its finest.
*ingenuity
finally subscribed this vid was fun
Imagine Jason appearing out of the fog with this beast! I expected a little more sound from the hood intake tbh
Can you please make a video on how a transmission with two final drives work? That for example Hyundai i30 n have.

Is there a good website, blog o vlog (no wiki) for all Mc Larence recent models with differences and specs, please? So so many model now. Thanks.
Could you do some sim racing videos? Hook up with Barry from Sim Racing Garage. Would be mega!
Nice video. I love sport muscular car 🤣. Btw what is the different road legal and not legal car? Is the "terms" legal here varies in each countries?
Would the top mount exhaust help w/ fording as you'd have less backpressure? Also, you'd think the flat bottom and diffuser with higher viscosity would cause even more downforce
Hahaha - well if the density is higher below the car than above... up force!
Another episode from Jason about planes that fly on the ground. ☺✔👍
Hi Jason, isnt this design giving the engine a colder intake vs the side mounted intake? It most definately is colder than a regular front bumper grille, but im curious about the intake temperatures in these two scenarios as the air is technically going through the interior of the car.
Since the engine is turbocharged, could they have used a non-elevated intake to suck in the boundary layer to reduce drag?
The last time I was in a car with no cup holder was my E36 hahaha, they had it as an option back then :D
You should do a video on dry steering
Thank you very much for this interesting video. Your thoughts will much appreciated regarding Toyotas newly announcement of hydrogen combustion engines, despite your old video showing its ill effects.
A similar scoop was on the McLaren F1, but it fed into the 6.0L V12 engine.
Will you do a video about the experience of driving a street-legal race car (with street-legal racing tires) in the wet? Is it just VSC constantly kicking in at the slightest application of the throttle?

Baller!
Btw can you go indepth to how the rain exits through the drain hole on the intake?
How effective were the headlights during this weather?
I drive the Los Angeles crest all the time! I believe i was driving that morning too!
What prevents the ingress of water/rain? And if there is holes further down to let the water out won't you loose the additional pressure (psi)
what is the relationship between engine load and temperature or vice versa? within RPM is constant
please reply ASAP
5:05 and lower resistance means less pressure loss so effectively it still acts as a slight turbo boost
So I wonder why they didn’t use the NACA duct? A lot of research went into extracting air from the stream while adding as little drag as possible. I guess it would have intruded in the cabin too much?
This also has some aerodynamic advantage over side intakes.
So what does this car use the vents in the doors for? Radiators only? Also, what would the vent in the cheaper cars be on the passenger side behind the B-pillar.
I do have a question. How does the vehicle handle leaves and bugs and other debris that enters the air scoop? Is there a receptacle that the owner can empty on his own? Or is it emptied when the car gets serviced?
I wonder if tavarish bought the interior carbon intake piece?
Can the roof scoop be added on a mclaren 600lt spider?
Is that a camera at the intake split inside the car?
How does this Les Snorky handle windshield washers?
Reminds me of a WW2 Era aircraft called the P-39 Airacobra. The air intake was right behind the cockpit.
