Despite Pandemic, Advanced Diesel Tech Notches Strong Growth

Despite a global pandemic, investment in new advanced-technology diesel commercial trucks in the U.S. grew by over 6% between July 2019 and December 2020 – now representing nearly half (49%) of all diesel commercial vehicles on the road, according to new research from the Diesel Technology Forum.

Twenty-three states exceed the national average. Indiana is the top state, with 67% of all commercial diesel vehicles being model-year 2011 and newer.  Since progressively cleaner diesel trucks were introduced in 2007 and 2011, significant clean air and greenhouse gas benefits have been realized.

“Results from the newest technology diesel vehicles are growing in the form of cleaner air and fewer greenhouse gases in communities all around the country,” says Allen Schaeffer, executive director of the Diesel Technology Forum. “While the promise of zero-emission commercial vehicles is growing, it may be many years, if not a decade or more, before these solutions enter the fleet in significant numbers. In the meantime, continued progress on improving air quality and lowering greenhouse gas emissions is essential and as this new research bears out, is being delivered primarily by investments in the new generation diesels.”
