Watch The McLaren P1's Hypnotising Wind Tunnel Tests

One of the most crucial factors in making a fast car is considering how much down-force the car has. Down-force describes the way air interacts with the aerodynamic design of the car to keep it onto the road. That way, the tyres are always firmly planted to deliver you the best possible acceleration and handling. The McLaren P1 is one such car for which downforce is crucial, but how does it all work? Take a look at how air sculpts these insane hypercars.

The P1 is automotive pornography, and seeing how it interacts with the world around it is just incredible.

It's important to note that cars like the P1 and any new additions to the line-ups of Ferrari, Lamborghini and Porsche aren't just exercises in straight-line speed or how fast a car can go round a corner before planting into the wall. It's about engineers making science their bitch.

The hybrid 903hp McLaren P1 hypercar comes out this year and it will set you back $1.27 million. Better get in quick, though: only 375 will be made.



    " and seeing how it interacts with the world around it is just incredible. "
    Err.. What world around it?
    The CG one?

    Also, I'm not sure how true this is, but I had heard that at least once upon a time, you couldn't register a McLaren for use on Ozzy roads.
    Something to do with McL not doing crash tests or something.

      This may have been true for the McLaren F1, provided any actually made it into Australia.

      But i know for a fact that the MP-412C is road legal.

      You are rightish. Not fully registerable. Club permit would be required for the F1.

    what wind tunnel tests, I only see some CG? Also the most aerodynamically advanced car in the world... Rubbish. If it was even close the the most aerodynamically advanced car in the world it wouldn't have side mirrors.

      It has to have side mirrors to be road registerable in most countries.

    And there was no wind tunnel test.

    I love reading Gizmodo comments where everyone who's ever attended a high school science class considers themselves better engineers than those working at McLaren.

    I am a mechanical engineer for a motorcycle racing team and can say that CFD (computational fluid dynamics) as shown in the video give extremely valuable information to the engineers and designers. A wind tunnel can give you data, but unlike CFD software, it can not suggest where improvements should be made. Every sports car/motorbike produced these days is built on a computer and put through CFD analysis before a model is ever even built. Once the CFD is satisfied, real world testing can go ahead. This method saves massive amount of money, time and results in an overall higher performing product

    There's a fully regoed F1 in Melbourne. Used to see it all the time. 'F1' number plate Victorian plates.

    in 2013 did I still just watch something in 4:3 ratio? wtf mclaren! Behind much! I would also suggest. This F1 technology you are designing your car with. Perhaps you can apply it to your F1 cars first haha you are doing terribly this year
