The faster you go the more power is needed.
To make this better you make the car go through the air easier (aerodynamics's)
or
Make more power.
The weight, aerodynamics, horse power and gear ratios all affect the speed of an automobile.
It changes the air resistance of the car - which is the controlling factor of top-speed.
it has to do with speed/acceleration. It can either be good or bad, depends how it's doneHummer - Not aerodynamicFormula 1 - very aerodynamic
race cars, airplanes
Wind speed may affect cars, effect change to aspects of cars or have an effect upon cars but, to say that wind speed effects cars is most likely a typo. I recommend changing the question.
planes, cars, trucks, and vans.
Horsepower and aerodynamics
Bad Aerodynamics.
The weight, aerodynamics, horse power and gear ratios all affect the speed of an automobile.
It affects you because you're an idiot.

Wind speed, aerodynamics and the weight of the kite
I reckon it is for aerodynamics so the car can have more speed and stay on the track.
Aerodynamics, weight of the car, horsepower of the engine, are all factors in the speed the car can travel.
Cars with good aerodynamics.
how the product (in this case the cart) is designed to achieve so it gets to the fastest speed and gets the greatest distance. the better the aerodynamics, the faster the rollercoaster will go and the worst the aerodynamics the slower it will go
