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."
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.
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.
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.
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.
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
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
Mclaren had given us an aircraft with a steering wheel ! So people driving these aren’t regular drivers they are McLaren’s Pilot . Let’s take this moment to thank their design and engineering team 🙌🏽 BRILLIANT 🤩
The only cupholders in my NA Miata are the little spaces where you can wedge a water bottle between the seats and the center console/arm rest lol. But hey, it works!
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! czcams.com/video/oQQ3nfIf6EE/video.html
Another reason for the separation of the roof scoop: The air going into the scoop is separate from the boundary layer, which keeps it from resonating like a flute. Military aircraft have "barn doors" to separate airflow into the engine ducts to keep them from making a hooting sound like someone blowing across the opening of a bottle.
5:00 Correction, adding pressure to the intake of the turbo charged engine increases the efficiency of the turbo/s, it will increase the effective boost map area of the turbo compared to a turbo relying only on atmospheric pressures. It is the same reason that vehicles use compound turbo charging 👍 14:40 Intake sounds like any 18yr old's 4 cylinder Pulsar / Miage / Honda with a pod filter 😁👍
Just know that I, and 2 other dudes will be the only ones that ever read your comment. The 3 of us personally thank you for clearing this up. I swear I haven't already forgotten your explanation while I type this
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."_*
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!
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?
I wouldn't say that turbochargers are unique in "sucking" air in. Any engine will produce some amount of partial vacuum when it pulls air in. Turbo/super chargers just create higher pressures *inside* the cylinders, which means they need a larger cross-sectional area for the air stream on the low-pressure side than the high-pressure side. Ram air can help deal with the partial vacuum regardless of whether the engine is naturally aspirated or turbocharged.
Those triangular airbrakes where the side windows meet the body? Also, everything behind that flat rear window has to be in turbulence, but I suppose that's a road legal requirement. When they can use cameras instead of mirrors and rear windows... It would be interesting to see this in a wind tunnel. But, it sounds cool and looks cool and I wish I had one!
10:20 I'd guess maybe you wouldn't want to wear the racing harness when you are just headed out to get groceries and having the standard seat belt would be considered a nice little amenity for standard driving, but EE seems to imply that the 3-point would be required by law even if something better is already in place?
Jason look at the weather this way, it's reason to ask for a "raincheck" from McLaren so you they can give you access to the car a 2nd time for a "proper" evaluation. yeah, if anybody understands BAD WEATHER it would be the BRITS (hint: we already know you've asked, and this has been arranged, however to be "cheeky" you're simply not sharing this info with us in THIS video).
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?
I should note that when McLaren released the MP4 12C, the exhaust was in the bumper, not below said bumper, so that McLaren could use a bigger diffuser. So if the exhaust is below that bumper again, where'd they move the diffuser's volume to?
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?
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?
How do they deal with water and stuff getting in? Oh nevermind you covered it. Though if they have drain holes to deal with water, wouldn't the air also go through those holes?
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.
Another great video but I have a pro tip from an automotive photographer. Maybe next time before you show the interior, give it a wipe down with a rag or brush. Dirt from your shoes can make a million dollar car look cheaper than it is. Otherwise keep up the great work.
Please Review the Mercedes GT Black Series(Fastest Production car on the Nurburgring) it's Front Engine & Rear Drive. Then review the 1,200 HP Mercedes Hypercar AMG ONE that comes out in a few months 🏆😁👍
A question for English native speakers: When can you use the s apostrophe genitive with things, like in "what is the roof´s purpose"? Instead of "what is the purpose of the roof?". Up until now, Ive used the s-genitiv sparingly with things, most often with "time" as in "in twenty years´ time", or with events like "WW2´s consequences". Thanks for your answers!
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.

Take my like and see yourself out.
I can’t afford the scoop!
Lol

Not only is he smart ( very) but he explains things so clearly that even a person vaguely familiar with these things can understand
For added performance, you can activate water vapor injection by turning on the window washer
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.
Good to know to raise my McLaren 620R when I need to ford some deep water
Indeed.
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
"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."
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.
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👍🏻
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!

I was caught off guard by that start up. Was not expecting that roar. 😳😍
Congrats, man. When I found your channel you were demoing a Nissan Leaf.
You earned the respect of the McLaren engineers that the chief one will talk with you about the car for ages. Cool.
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
At this point, I'm just watching these videos just to see Jason's genuine reaction when driving these supercars.
Jason, you're able to create interest for things I didn't care about before. You're amazing
Excellent review, as usual. We have so many extraordinary cars - truly the Golden Age. Thank you!
The weather really wanted to ruin your vids 😂

Can you both tell us more please? I'm on the edge of my seat
Damn. Driving a $300K car and not being able to see more than 50 feet in front of you because of fog.
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 are a true professional making such an interesting video in challenging (for that car) conditions. I learned a ton as usual.
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.
Reminds me of a WW2 Era aircraft called the P-39 Airacobra. The air intake was right behind the cockpit.
Aaahhh...my favorite grandpa on youtube is back.
The only cupholders in my NA Miata are the little spaces where you can wedge a water bottle between the seats and the center console/arm rest lol. But hey, it works!
5:05 and lower resistance means less pressure loss so effectively it still acts as a slight turbo boost
I drive the Los Angeles crest all the time! I believe i was driving that morning too!
Hey man, do a video on how the Mercedes Project One Suspension works. It's so simple but so novel!
The snorkel! I love it!
Can you please make a video on how a transmission with two final drives work? That for example Hyundai i30 n have.

You can cut out a vent to get dynamic a/c from that scoop inside. Faster you go,the air speed increases and cools you down faster ! (Sarcasm)

Love the looks, not sure I could deal with the reliability issues of modern McLarens.
I'm sold. Going to swing by and pick one up tomarrow.

Those intake scoops inside right above your head must make that think howl like a wookie. Would sound killer but be crazy loud
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?
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
A similar scoop was on the McLaren F1, but it fed into the 6.0L V12 engine.

That looked like early morning in the Canyons. We didn't get the rain in LA. Should have checked with Matt Farah first and gone to Malibu.
@engineering explained ?
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)
7:17 Dude! Smooth!
While you were talking about drag coefficient I got struck with the question: why not a NACA duct?
