Is it possible for a veyron to reach big speeds 700+ km/h with aerodynamics like that?

[filip4428]

so, in theory, if u have motor strong enough to reach that kind of speed, if you have road long enough, will he reach it or will he just lose control and crash/go airborne?

Plz i need detailed answer from someone who knows what he/she is talking about... Thanks

Well, here's some information to get you started - from the Wikipedia article on the car:

 

When the car reaches 220 km/h (140 mph), hydraulics lower the car until it has a ground clearance of about 9 cm (3.5 in). At the same time, the wing and spoiler deploy. In this handling mode the wing provides 3,425 newtons (770 lbf) of downforce, holding the car to the road

 

So the question is then how much lift the car's body creates at that speed - if it's greater than the downward force then it would leave the ground. I'm not sure about the maths necessary, but I expect someone here can provide an equation.

i'm courious, what force will be created at such speeds that would lift a car off a ground?

and yes, equation would be rlllly helpful 2

First, no tyre can rotate at 700km/h. You need wheels of plain metal.

 

Second, even with downlift, a normal car is too sensitive to wind, accidental uplift, and so on. Even on the best possible flat terrain. There are enough examples of endurance cars taking off (Le Mans and other places) at only 300km/s despite downlift.

 

Such a speed needs the special aerodynamic design used for speed records:

heavy, narrow, and of special shape.
