When researching your future purchase, you might want to consider the fact that improving vehicle aerodynamics is an effective way to save on fuel. While engine size, fuel choice and overall engine efficiency can increase mileage and reduce fuel consumption, vehicle aerodynamics can also have a significant impact on each of these factors. It is estimated that almost two-thirds of an engine's energy is used to overcome aerodynamic drag at highway speeds. Improving aerodynamics allows a vehicle to slip through the air with less resistance, decreasing the amount of energy output required from the engine.
