Ecomodder and many other web sites, including those from automotive racing, indicate varied forms of aerodynamic design for vehicles. Some of their designs are dictated by what they wish to achieve, or in some cases, by racing requirements.
Production cars have general sweeping lines from a low point in the front, up over the hood and windshield, over the top of the car to the area near the rear window. From there, things vary greatly from hatchbacks to vehicles which implement downward lines to the trunk, then on to a sharp edge, and then downward to the bumper. Some sporty vehicles have a rear spoiler and possibly an aerodynamic wind spoiler under the front bumper.
However, true racing vehicles and energy-saving prototypes use far different designs from production vehicles. Some suggest a rear boat tail upward. Some suggest a boat tail that is straight. Some suggest rear spoilers. Some suggest sweeping lines downward to the the lowest part of the vehicle. Is there a best design for the rear of a vehicle for aerodynamic design and least wind turbulence?
