U.S. and Canadian Class 8 natural gas truck retail sales for the first 11 months of 2020 dropped 9% year to date compared with 2019, according to a quarterly report from ACT Research.

“Sales of natural gas-powered vehicles as reported by the six major truck OEMs, who account for approximately 60% of the heavy-duty natural gas market, were mixed in the September to November time period, with October experiencing both sequential and year-over-year gains, but the other two months faltering for both time period comparisons,” Steve Tam, vice president at ACT Research, said. “As a result, sales continue to whittle away at the year-to-date deficit.

“Through the first 11 months of 2020, reporting OEMs have sold nearly 2,900 natural gas-powered Class 8 units, down 9% year to date. For comparison, total U.S. Class 8 sales were down 33% for the same period.”

In addition to the quarterly report, ACT Research created an upgraded online total cost of ownership and operational calculator, which now includes the societal costs in metric tons of CO2 per year.
