Very true! On the surface, it presents a fact that is probably very surprising to most people because 99% of people probably don't know how aerodynamics work and how Cd is measured. Take for instance: tire width is a significant contributor of coefficient...
The drag coefficient (Cd) number has to be multiplied by the cross-sectional area. The Volvo's Cd has to be multiplied by its (larger) cross-sectional area, whereas the sports car would seem to have a smaller cross-sectional area. Therefore, the boxy car ...
The key stat is the the drag coefficient times the cross sectional area. Thats called the βdrag areaβ That Volvo might have a Cd of 0.32 but its drag area is around 0.32 x 2.5 = 0.8 sqm The Countach has a Cd of 0.42 but due to a smaller cross section, it ...
But many sports cars generate a lot of drag because next to the high Cw that they need for cooling and downforce, they are also very wide, so the frontal area is not that small, either ππ»
