Figures from 2016 show sales in propane autogas vehicles have increased nearly 8 percent over 2015, according to the Propane Education & Research Council. The more than 14,000 light, medium and heavy duty propane autogas trucks sold last year is the most in a single year since 2012. The data shows that there are almost 200,000 such vehicles being used in public and private fleets in the U.S. as of 2016.

“We’re thrilled to see so many new fleets take advantage of all propane autogas has to offer,” said Michael Taylor, director of autogas business development for PERC. “We don’t expect propane autogas sales to slow down in the future, especially as more fleet owners and managers experience the lower cost of ownership of the fuel compared to other options out there.”

Approximately one third of sales were for OEM dedicated vehicles while the other two thirds were aftermarket conversions. PERC forecasts another 79,900 propane autogas vehicles to be added to the highways in the next three years.
