Hello auto maniacs!
So, as you may not know yet, the horsepower required to overcome aerodynamic drag is approximately 80% on a flat road at 40 km/h speed, and it is proportional to approximately speed3.
What is your excuse not aerodynamically enhancing your own car?

Anyway adding an aerodynamic tail will give you 30%+ reduction in fuel consumption, that does not involve that much engineering.

That's why car manufacturers don't put them on their hatchbacks, right? What do their teams of engineers specialized in aerodynamics know, right? It's not like they put spoilers on the rear to induce better flow separation, thus decrease drag, right?
Next you're going to tell me a heating coil around your fuel line will raise your MPG by 50 or something.
Shoo shoo, Tesla shill. Nobody except people who don't know what to do with all their money like your overhyped golf tanks.

yeah that car has better aerodynamic features going backwards :)
i wonder who you work for, or how dumb you are. if you are just dumb, study these images:
cross section of an aeroplane's wing, that flies efficiently above 200 km/h speeds
i you still don't know which side is leading and trailing then you fail at failing
Spoilers add drag, create downforce at the cost of fuel.

Your 2 ton rolling box is very practical to take you (alone) to the shop nearby burning 10 liters of gasoline per 100 km
I have no problem with you having a hobby, and rolling arund in a box designed aerodynamically for 30 km/h.
I was just pointing out that for efficient travel, aerodynamic shape is needed.
Another question that the engine is very inefficient by design, and the whole thing weights over a ton..

Well, an aerodynamic vehicle could be 10 times larger than a "car" to get exact same aerodynamic drag, what you fail to interpret is at least 10 times more aerodynamic shape is possible at the exact same ize as your shitty box-car.
That could mean 1 liter / 100 km instead of 10 liter / 100 km.
image related, it consumes 0 liter / 1000 km, uses sun power.

Your ghetto physics is almost a beginning of something, but one needs to realize that turbulence = wasted power.
The greatest potentiol of streamlining is atthe rear, not at the front.

i did not search for tesla stuff btw, it was just the only one i found, gasoline IC engine people seriously does not give a fuck about aerodynamic efficiency it seems.
It is all good to drive with under-cambered wings at front and rear to generate downforce and accelerate even faster and burn more fuel, if you are only into racing.

>wings at front and rear
Name me one road going car from a major manufacturer that has wings both and the front and the rear.
Furthermore, name me three road going cars from a major car manufacturer in which the wing is not mainly there for aesthetics.
Aerodynamic downforce is negligible in road use.
Are you drunk or retarded?

If by "search" you meant the first 2 pages of google… sigh.
IC engine people care about aerodynamics exactly as much as anyone else. If IC people did not care about aerodynamics, we could still have cars with designs that look good, not modern day "squeezed through a tube" designs.
