A new definition of long haul will help in evaluating alternative fuels and drivetrains, says NACFE’s Mike Roeth.
The words we use to describe something influence our perceptions, understanding, even our actions.
Consider the words long haul. What image pops in your mind when you hear those words? I am guessing for most of you it is a Class 8 truck with a sleeper cab driving across the country. You probably also picture a driver who is away from home for weeks at a time sleeping in their truck and taking a shower and eating at a truck stop.
While that is one version of long haul, it is not the only one.
The North American Council for Freight Efficiency believes that long haul should include both over-the-road operations as well as longer regional haul return-to-base ones.
In addition, long-haul operations are not only completed in sleeper tractors. There is a place in long-haul trucking for day cabs. In fact, data from ACT Research shows that day cabs make up 40% of the Class 8 tractor market.
Redefining Long Haul Trucking
What defines long haul is the total number of miles a truck travels in a day — even if those miles end up with the truck back where it started.
NACFE’s definition of long haul is 500 to 600 miles, and those miles can be racked up driving 250 or 300 miles in one direction and turning around and driving those same miles back, as often happens in less-than-truckload operations.
NACFE sees “long haul” in two different segments, one of which returns to base.
For comparison, we define short regional haul as less than 50 miles out and back for a total of 100 miles and medium regional haul as 100 miles out and back for a total of 200 miles.
The distinction that long haul includes out-and-back routes and not just over-the road ones might seem insignificant when you talk about diesel-powered trucks, since there is a widespread fueling network.
But understanding the various routes that make up long haul is important as we move through trucking’s Messy Middle — a time when fleets have a variety of powertrain solutions to choose from.
While there are many options, fueling and/or charging infrastructure for some of the alternative powertrain solutions is not available everywhere. That means fleets must carefully consider which routes will work for vehicles with alternative powertrains.
There’s a general belief that battery-electric trucks aren’t suitable for long-haul operations. But one thing we discovered during Run on Less – Electric Depot was that longer ranges are possible with battery-electric vehicles.
For example, one Tesla Semi deployed by PepsiCo had a range of 410 miles on a single charge. One completed 1,076 miles in a 24-hour period with several instances of opportunity charging.
Run on Less: Exploring the Messy Middle and Long Haul Trucking
NACFE’s upcoming Run on Less – Messy Middle is designed to bring clarity to long-haul trucking by learning about the benefits and challenges of multiple powertrain solutions, including:
However, to accurately analyze the performance of these different trucks, we need to use common language and common definitions of exactly what we mean by long haul.
Even though Class 8 long-haul trucking accounts for only 9% of the total trucking market, according to a National Renewable Energy Laboratory report, it contributes 48% of trucking’s emissions.
The trucking industry is changing, and so too must we change the language we use to define things.
NACFE believes that long-haul return-to-base operations will most likely be handled by Class 8 day cab tractors, while long-haul over-the-road operations will still be dominated by sleeper tractors.
It is important to note that for a variety of reasons, regional haul using day cabs is growing. This growth in return-to-base operations will help fleets determine where best to locate truck fueling or charging for alternative fueled vehicles.
Because of the current proliferation of powertrain solutions, and the growth in regional haul, the way we define long haul should include longer return-to-base operations as well as the more traditional over-the-road one.
