Whether you drive a used truck or own a fleet, chances are you’re looking for ways to maximize fuel economy. Besides choosing an efficient engine, one of the easiest ways to improve fuel-efficiency is to reduce drag by making the vehicle more aerodynamic. When you do a fuel economy side by side comparison with a truck that is less aerodynamic, the differences are too great to ignore. International Used Truck Centers has some suggestions for aerodynamic enhancements that’ll save you thousands per year on fuel fill-ups.
Aerodynamic drag is the force that opposes an object’s motion. When a vehicle — no matter the size — is designed to allow air to move fluidly over its body, aerodynamic drag will have less of an impact on its performance and fuel economy. Heavy trucks burn a significant amount of fuel as they power through air resistance. In fact, more than 50% of an 18-wheeler’s fuel is spent reducing aerodynamic drag on the highways.
You can always improve the aerodynamics of your semi truck, be it an International ProStar or Freightliner Cascadia. Here are a few parts and design features you should consider implementing on your used semi:
International trucks are designed with aerodynamics in mind, so you don’t have to spend a considerable amount of time and money on parts and accessories to help make your semi truck more efficient. The ProStar, for example, boasts smooth radius edges and a sloped hood that not only make it look more streamlined, but minimize aero drag.
And that’s not all. Its A-pillar design and windshield radius were developed after extensive wind tunnel testing, while the cab-to-sleeper and cab extenders cut down turbulence. Set-back front axles simplify loading while creating an airflow region along the front wheels, allowing the air from the engine compartment to travel through the front grille.
Another important aspect of your truck that affects fuel economy is its tires.
