Diesel Fuel Market: Medium-duty Trucks
Calculations based on publicly available data indicate that approximately 2,462,250 medium-duty trucks in the U.S. in 2018 were using diesel fuel. During that year, Diesel Technology Forum asserts that 75% of all commercial vehicles used diesel fuel.
Medium-duty Trucks in the U.S.
- According to Freight Liner, medium-duty trucks belong to Classes 6-7 and weigh from 19,501 - 33,000 lbs. In 2015, Trucking Info reported that there were 1.4 million Class 6 trucks and 1.5 million Class 7 trucks in the U.S.
- In the U.S., a total of 62,000, 63,000, and 72,000 Class 6 trucks were sold in 2016, 2017, and 2018, respectively. Likewise, around 60,000, 62,000, and 64,000 Class 7 trucks were sold in 2016, 2017, and 2018, respectively.
- Therefore, when summed up, there are approximately 1,597,000 Class 6 and 1,686,000 Class 7 trucks in the U.S., as of 2018, which is equivalent to about 3,283,000 medium-duty trucks in the U.S.
Medium-duty Trucks That Use Diesel Fuel
- According to the Diesel Technology Forum, in 2018, almost about 75% of all commercial vehicles were powered by diesel engines. It is assumed that diesel engines powered 75% of all medium-duty trucks in 2018.
- Therefore, 75% X 3,283,000 medium-duty trucks — the total number of medium-duty trucks in the U.S. that rely on diesel fuel.
- So, (75 ÷ 100) X 3,283,000 = 2,462,250 medium-duty trucks in the U.S. powered by diesel engines.
Medium-Duty Trucks That Use Diesel Fuel in California
- According to CBS San Francisco News, California has about 1.5 million medium-duty and heavy-duty trucks on the road.
- The Coalition for Clean Air estimates that approximately "one million heavy-duty diesel trucks" operate in California each year.
- Therefore, there are about 500,000 medium-duty trucks that operate in California each year and likely to use diesel fuel.
The lack of hard statistics indicating the total number of medium-duty trucks in the U.S. prompted the need for triangulation. Using the number of medium-duty trucks in the U.S. in 2015 as the base year, and adding the total number of medium-duty trucks sold for the years 2016 through 2018, we were able to estimate the total number of medium-duty trucks in the U.S.
Next, we used data indicating that approximately 75% of all commercial trucks in the U.S. are powered by diesel engines to establish an estimated total number of medium-duty trucks in the U.S. that rely on diesel. For California, the numbers are publicly available and mentioned across news articles and reports by local and statewide media outlets, energy companies, and industry and market research reports.
