NASA’s contributions to truck design have greatly reduced fuel consumption, perhaps by as much as 6,800 gallons per year for an average vehicle.
Nearly all trucks on the road have been shaped by NASA — literally. Agency research in vehicle aerodynamic design led to the curves and contours that help modern big rigs cut through the air with less drag. NASA’s contributions to truck design have greatly reduced fuel consumption, perhaps by as much as 6,800 gallons per year for an average vehicle.
