- The air itself consists of vibrating / moving molecules. Do not overlook the makeup and properties of the medium which is impeding the movement of the vehicle.
- The paint finish; The smoother the paint finish the easier it is to have these air molecules move along it’s surface. every car has a paint job regardless of it’s design, so the paint finish itself is impeding the movement of the air.
“What!?” I hear you exclaim! “So you have figured out something ALL the car companies have overlooked!!?” Well I think so, firstly if you are moving though a crowded street like in a major city in rush our, do you change your shape so you can surf through the people the quickest? This is what car manufacturers do, they make the car shape the best for forcing the air out of the way. (image for illustration purposes only)
Here is a fundamental error! most of our teachings & learnings are based around “Force!”. Our perception is the only way to move things is to force them to. Try forcing people out of the way on a busy street! It is possible to do this, but not the best way to move through the crowd, I think you would agree. What we actually do is use the co-operation of the people around us to help us move through the crowd. If we were running and the crowd was packed tightly (this is relatively what a car body is in relation to the air molecules around it), we would require great force if there were no co-operation from the people around us to let us through.
Point 1 : Air molecules as the people on a crowded street, need to co-operate with our car body to let us through in the easiest way with the least effort.
Imagine having the co-operation of all the people on that busy street so they are parting and then assuming their original path as you moved along as if you were surrounded by a clear invisible bubble. You could run along that street as if they weren’t even there! Imagine how that would transform travel as we know it! Cars moving as if there was no air slowing the car down! Amazing!
Ok so the most fundamental thing to overcome; movement through the air, has been realised. Next is the paintwork on the car. So all cars have paint finishes on them, they are powder based for consistent even coverage. Some are dipped in an electrically charged bath of primer and finishing coats for extra anti-corrosion coverage, (reaching more areas than spraying could therefore no unpainted surfaces where rust can occur).
Paint technology has come along nicely in it’s various colours, and finishes : Candy, Chameleon, Metallic etc. If you look at a smooth surface under the microscope or electron microscope, you will find that the surface closely resembles a mountain range! The picture below is of a car paint pigment.

Smooth is only smooth relative to us humans, but other small paticles such as air molecules will have a hard time moving over a rugged style surface at great speed without it’s co-operation, and even with it’s co-operation, its still a very bumpy path to say the least!
The answer here is:
Make the surface smooth relative to the air molecules / partilcles and create an easier path and therefore less resistance to the air & rain snow etc.
This will also lower car maintainance and dirt paricles will no longer have nice crevices to accumulate in and make the car dirty / rusty etc. How can this be done? Well the answer is simple, we already have the technology in products like Rain-x, all we have to do is put more money into researching our existing paint technologies.
The Science Bit
To any scientist reading this may seem like it’s rather naively put, without a scientific background. To that I say, this : The most fundimental part of this information, or a soft jabbing with my elbow, to you the scientific creators, is that the behaviour of particles when they are travelling over a microscopically smooth, perhaps nano-smooth surface will act in an altogether unexpected and very beneficial manner reducing drag so much, as we will only need half the size / power of our engines. These are the areas where research is somewhat easy to begin as all of these technologies exist, they are simply not being applied in the right areas in the right way.
Also once we are capable of comfortably reducing drag by that amount and of course fuel consumption, we can then work on electrical ways to direct airflow as to produce desired roadholding like we now archaically use spoilers for. We could also shape the surface of the paint (nano shaping) to produce downforce / desired airflow, similar to ground effect. We all know how weather conditions can be magnified or diffused depending on the terrain the wind/rain/snow is moving over. The nano shaping could give or aid to this effect on air moving across a car body. We could even have air flow be very easy over a cars body apart from the areas we want the air flow to push the car into the road (for more grip). This would mean less or no spoilers needed, and no drag indroduced to produce downforce. It also mean a return to flamboyant car design , as the shape of the car would be much less important as aerodynamics would be advanced enough to make the car aerodynamic, regardless of shape!
