We are edging closer and closer to the introduction of 2018 models. Why are the 2018 trailers so significant? It is because the 2018 model year is the first time that there will be efficiency and green house gas (GHG) standards for tractor trailers regulated by the DOT and EPA. What was GHG Phase 1? What does this Green House Gas Phase 2 mean for truck trailer manufacturers? What parts will manufacturers need to change on their trailers? What are the goals of these new standards? Let’s take a look at GHG Phase 1, the new GHG Phase 2, and how the truck trailer industry is being impacted.

GHG Phase 1

The GHG Phase 1 standards are directed at heavy trucks, dividing them into three broad categories. The categories include combination tractors, vocational vehicles, and heavy-duty pick-up trucks and vans. While Phase 1 has been focused on truck and tractor manufacturers, Phase 2 directly affects manufacturers.

The Effect on Manufacturers

These new standards mean that manufacturers will have to produce trailers that meet GHG Phase 2 standards. This can be accomplished in a variety of ways including using tires with low rolling resistance. The biggest improvements, however, can be made in modifying construction to be more “streamlined”, therefore improving fuel efficiency and creating less CO2 gasses.

Interestingly enough, many have already been using aftermarket devices on their own accord to improve mileage. Some manufacturers have already been producing vehicles that help reach, or at least get closer to these standards.

How Small Aerodynamic Changes Work Together

By combining a series of relatively small changes, these Green House Gas Phase 2 standards can be achieved by truck trailer manufactures as long as they are working on those changes now. This will not necessitate a ground up redesign of trailers but by implementing changes that are seen on the road today. Boattails or fairings have been proven to save 1-4% on fuel. Skirts and fixed side fairings have been shown save 1-5%. Front trailer fairings that minimize the gap between truck and trailer can save another 1-4%. Making these three changes alone can reach the goal of Phase 2 standards. As you will see, the changes can really add up.

The Goal of GHG Phase 2

The basic goal of Phase 2 is to save on fuel and CO2 gasses, starting at 5%. In real numbers, this can prove to be significant. Based on the lifetime of vehicles sold under the standards, there will be a mind-boggling 1.1 billion barrel savings. CO2 emissions are expected to be reduced by about a billion metric tons. At the same time, fuel savings is expected to reach $170 billion dollars. As you can see, a 1% savings here, 3% savings there, can add up to some serious savings.
