Wings provide aerodynamics, to both improve handling and make the car faster.
Edit:
Wings provide what is commonly known as downforce. This form of drag forces the cars into the ground when the car is traveling at significant speed, and increases as a function of speed. This downward force allows much more grip in turns due to the car "weighing" more as it is pushed into the car, because friction is equal to the coeficient of friction multiplied by the weight of the object (Or force adhering the surfaces together). So, although they do indeed make the cars go faster around turns, these wings significantly reduce top speed as well as acceleration due to the tremendous drag that they produce.
You cant buy formula one cars. You can only win them.
None.
In batteries.
There are 2 Ferrari Formula 1 cars for sale in the Ferrari dealership, and there's a Formula Gran Turismo for sale at 2500000 Credits at the Online Dealership.
Formula 1 cars have high drag coefficients because they are open wheel, and they have large air dams and spoilers to create downforce.
different manufactures make different cars according to there teams.
The rules which participating cars must follow.
Yes there are formula 1 cars in gran turismo psp.
Formula 1 cars do not defy gravity; they are actually designed to aid its effect by the use of aerodynamics to push the car harder onto the surface. You may be referring to the fact that it is possible for a Formula 1 to drive on the roof of a tunnel, such is the force created by the wings at high speed.
Sometimes they use Nitrogen.
Depending on circuits
cars have wings.
