The importance of good fuel economy is essential. Fuel is one of the largest variable expenses for every truck fleet.

Industry studies have shown that for many fleets, fuel accounts for as much as 25 percent of total operating costs. Therefore, even a small gain in fuel efficiency can make a big difference.

The challenge is to consume fuel in the most effective way possible.

Forces to Overcome

Simply stated, fuel consumption is a function of the power required at the vehicle’s wheels to move it.

Fuel is consumed by the engine to make horsepower. Horsepower is used to overcome all of the forces that are trying to hold the truck back.

Consequently, a truck that travels down the road with minimum resistance will use less horsepower and consume less fuel.

Key Influence Factors

There are a number of major factors that have an impact on vehicle fuel consumption.

Among these are aerodynamics, vehicle components and equipment; engine, accessories and powertrain efficiency; tire rolling resistance; environmental conditions; fleet management technology and telematics,; driver behavior; and vehicle maintenance.

A fleet can improve its fuel economy through such measures as making informed equipment choices, adding aerodynamic devices, adopting no idling technologies, skillful fuel purchasing and staying current on new technology for improved monitoring and fleet management.

The intent of this special supplement is to provide some insight and guidance on better managing fuel consumption. For this, we invited OEMs and components suppliers to provide useful information and recommendations.
