1. What is the purpose of a roof scoop?
2. How is the intake air routed to the engine?
3. What intake location does a roof scoop replace?
4. Why relocated the air intake?
5. What advantages does a roof scoop offer?
6. Why is the roof scoop elevated off the roof?
7. Can a roof scoop increase power?
8. Does the McLaren's roof scoop increase power?
9. What are the aerodynamic effects?
10. Why is the roof scoop wide and flat?
11. Does the roof scoop impact downforce?
12. Does the 620 feature racing aerodynamic features?
13. How does the roof scoop handle rain?
14. Does the roof scoop improve the 620R's fording depth?
15. How much does the 620R weigh?
16. How many cupholders does the 620R have?
17. What does the roof scoop intake sound like?

    what is the relationship between engine load and temperature or vice versa? within RPM is constant please reply ASAP

    Jesus, How do you humbly go on from driving this to your normal cars. I guess that just comes with the territory and is still an experience!

    Another advantage is when there is a flood, you can use your car as a submarine

    The color of the car looks like a gradient. Is it a light effect?

    Does it have electric power windows?

    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 would think this scoop would kill all turbo Lag I would expect nothing less than Tesla p100d ludicrous mode level acceleration

  • Porghvam

    $300,000 , engine noise megaphone, slower 0-60 than a Tesla Plaid. Nothing “clever” going on here.

    The ONLY thing i don't like about this is normies might think its a fake roof scoop. But the true Chad's don't care about what the normies think.

    No cup holders, no way I would buy the car, lol.

    5:05 and lower resistance means less pressure loss so effectively it still acts as a slight turbo boost

    What would a "three-way differential", or rather, a differential for an AWD three-wheeler look like? (Preferably without just attaching multiple separate differentials to eachother) I don't know what has possessed me to need this knowledge.

    Jason, you're able to create interest for things I didn't care about before. You're amazing

    That fact this vehicle exists is an abomination to humanity. It celebrates the the excesses and greed of the most unconscious humans that place their fragile egos before the wellbeing of his or her own society. " it is easier for a camel to pass through the eye of needle than for a rich man to get to heaven".

    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 fully expect vents and ducts to live on long after cars no longer consume air.

    mi 2000's Peugeot 306 don't have cupholders too. So i'm concluding that i drive a racecar[1]. [1] The Clever Engineering Of McLaren's Roof Scoop. Engineering Explained. April, 2021.

  • PenkillerDIY

    higher turbo inlet pressure = less pressure ratio = less power required from the turbine = higher wastegate duty cycle/higher wastegating percentage = less backpressure = better volumetric efficiency = less fuel consumption, which McLaren doesn't care about, but also = less heat...

    It almost sounds like McLaren is actively trying to criticize EVs here

  • PKking

    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!

    Ford RS2000 did it first.

    Is this the same car Rob Spaghetti got rock chips all over?

    A boat? What about if you drive like a regular person and go slowly through a puddle so you can do under water launches? What is the maximum fording depth in that case??🤔 Or let's say you are trying to hide in your $3 million McLaren, and the only place is a puddle, how deep can you go and still be driveable when needed

    Is that a camera at the intake split inside the car?

  • tigerrx

    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?

  • tigerrx

    The next iteration of this car? Bullhorns like the MP4-23 and a new center console pocket to hold all your speeding tickets. Fear the Fram (ram drag force)!!!

    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)

    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.

    i mean my bmw e38 has cup holders but they might also be the worst cup holders ever made so its pretty much the same as this mclaren

    Shame about the fording depth. I'm afraid that's a deal breaker for me.

    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?

    The last time I drove a vehicle without a cup holder was today. My car has none so now it's a race car!!!

  • pkt1213

    89 Porsche cupholders in the 924/944/968. I also have an Audi S6 which does have "cup holders" but only if you want to douse your console or smash it with your elbow.

    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?

    Why does the car weigh so much of they are focusing on weight reduction? 3,000 lbs is still a very heavy car!


    Whats the roof scoop for mitsubishi evos used for?

    "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."

    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)

    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
