Clean diesel trucks now make up 41 percent of all medium- and heavy-duty diesel commercial trucks in the U.S., according to new Diesel Technology Forum (DTF) analysis of IHS Automotive vehicles in operation statistics.
“Because diesel overwhelmingly dominates the heavy-duty truck sector and is also the number one power source for medium-duty vehicles, the transition to newer generations of clean diesel technology is significant,” says Allen Schaeffer, the Executive Director of the Diesel Technology Forum. “Beyond the clean air benefits, Model Year 2010 and newer trucks also achieve three to five percent improvements in fuel economy and lower emissions of greenhouse gases.”
“California has the largest fleet of commercial truck registrations on an absolute number basis,” he says. “However, it ranks near the bottom for adoption of newer trucks on a percentage basis, based on our analysis.”
