  1. When making car designs more aerodynamic, engineers look to the most aerodynamic shape in nature: the teardrop. The teardrop has round, smooth sides that taper off. This configuration is ideal for allowing air to flow by easily, passing around its smooth edges and falling off gently at the end. Cars that closely follow this pattern are more aerodynamic. For example, the boxy Volvos of earlier years were more affected by drag than their more modern counterparts. SUVs, which usually are square, don't have great acceleration because they lack aerodynamics. In contrast, sleeker sports cars have round, smooth sides, which help the cars move through the air with greater speed.
