The car manufacture-ers use this as a "ploy"! If you are going under 80 MPH aerodynamics is not a real problem. It is however -in airplanes because of the speed they fly, - here "drag" due to "wind resistance" is very important!
Our "modern scociety" has been convinced that aerodynamics are very important, this is why they build cars that are more or less 'teardrop" shape, and so close to the ground only "young"people can get in them! It is true that a tall-flat-wide frontal area on a vehicle presents wind resistance (such as the front of a semi-truck trailer! But this is pretty extreme, and cars are not built to be "haulers of this type".
It is just the faster you drive - the more "drag is produced by such shapes! Driving at 100+ mph on the "Autobahn" in Germany makes a big difference in gas mileage, (and acceleration). However the fastest speeds that are legal in USA (as far as I know) is here in Texas, -- and it is 80mph. This is about where drag really starts to be a major factor, and aerodynamics starts to really matter!
Ii have a 1922 Model "T" ford coupe, which resembles an "old time "telephone booth" in aerodynamics. It only gets between 25 and 35 mpg - with a carbureter that is next to a "tomato can with a damper plate in it"! Since it travels less than 40 mph on adverage, it really doesn't matter that the shape is flat wide and high! However "crosswinds" that are severe sometimes makes it "sway" a lot in gusts! By the way, at 67 years of age, I can get in and out of it without laying down and "rolling in" like my wifes 93 Ply. Acclaim!

Research in, and practical applications of, vehicular aerodynamics has done more than just improve fuel economy to a limited degree. Although maybe not widely known, a vehicle's frontal area is as important to the overall aerodynamic coefficient (fuel economy) as is the body shape. Better aerodynamics also helps reduce wind noise, improves handling and promotes stability. Slicing through the air is, and always was superior to pushing through the air.
I do enjoy driving and working on my old cars, but the contemporary transportation market has never offered a wider choice nor better products than it does now.

No, this would not artwork. each and all the means from the moving air is generated by utilising the motor moving the vehicle forward. that is like attempting to apply a fan to means itself by utilising blowing a wind turbine. The means loss from the extra wind resistance could be greater suitable than the means generated. that's the comparable with utilising the rotational means of the wheels. in case you are attempting to sluggish the vehicle down on the comparable time, then it works (regenerative braking).
