对一个矩形的汽车形状和两个详细的，缩尺模型卡车的风洞测量已被用来确定前，后边缘的几何形状，使气动阻力最小化。为商用车设计目的，确定了足够详细的最佳配置。在大型风洞中对全尺寸直线卡车进行的模型缩尺测量与有限测量的比较支持对这些试验结果的解释。
Wind tunnel measurements on a rectangular vehicle-like shape and on two detailed, scale-model trucks have been employed to define the front and rear edge geometries that minimize aerodynamic drag. Optimum configurations are identified with sufficient detail for commercial vehicle design purposes. Comparisons of the model-scale measurements with limited measurements on a full-scale straight truck in a large wind tunnel support the interpretation of these test results.
