According to the recently released NA Commercial Vehicle On-Highway Engine OUTLOOK, published by ACT Research and Rhein Associates, engines over 10 litres are projected to account for more than 85% of the Class 8 production between 2020 and 2024, and the trend to smaller displacement engines is expected to continue.

“Although the over 14L engine category will remain the largest segment in 2019, there is a trend to smaller displacement engines in the over 10L market segment for Class 8 trucks and tractors, with an acceleration prompted by new emission regulations expected in 2024,” said Rhein Associates president Tom Rhein. 

Regarding Classes 5-7, Rhein said that in this market, the current metric of interest is gasoline penetration, which continues to see share gains.

ACT Research president and senior analyst Kenny Vieth said that diesel power is under attack long-term for use in on-highway commercial vehicles.

“Alternative power is being developed, tested, and refined, even as diesel engines are transitioning to become more fuel efficient and clean. Emission regulations are one of the main drivers of alternative fuel adoption, which is why the Engine OUTLOOK includes a section on the commercial vehicle regulatory environment.”

The latest NA On-Highway Engine OUTLOOK published by ACT Research and Rhein Associates highlights power-source activity for CV GVWs 5-8, including five-year forecasts of engines volumes and product trends. The Engine Outlook ties to the detailed NA CV vehicle forecasts published monthly by ACT in the NA OUTLOOK.
