The McLaren 620R has a prominent feature protruding from the roof - an air scoop! So what exactly is this roof scoop for? This video will look into the engineering of roof scoops, and answer the following questions:
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?

Hope you enjoy the video and learn something about roof scoops and the McLaren 620R!

    $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.

    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.

    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.

    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...

    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

    "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."
