Looks can be deceiving. There's a thing called "naive aerodynamics" wherein the observer believes that if a car LOOKS sleek and slippery, then it must excel in aerodynamics.
Oddly enough, this is not true. Sleek looking cars can have substantially higher CD numbers than cars that appear clunky and "edgy".
Of course, automakers are not striving for the lowest drag--they strive to create an efficient CD along with catchy styling that make you want to buy the car!
