Auto analyst who favors electric cars points out emissions, fuel efficiency values in latest Class 8 clean diesel

It was pretty clear to see, even for an auto analyst who owns an electric car. Class 8 trucks with advanced diesel technologies have been beating out electric powertrains in terms of sparing the planet and people from emissions.

Not only that, but they’ve been saving fleets billions of dollars in fuel.

“There’s been about a 98% reduction in both NOx and particulate matter since 1988, which is a pre-regulation time period,” Casey Selecman, director of powertrain forecasts at AutoForecastSolutions, explained Wednesday during a Diesel Technology Forum webinar revealing emissions and fuel efficiency gains that the country’s workhorses have been making thanks to ongoing improvements in engine efficiencies.

One of the biggest diesel advances, selective catalytic reduction (SCR), helped pave the way for a carbon dioxide reduction of 202 million tonnes for model year 2007 to 2020 Class 3 – 8 commercial vehicles, according to research findings released today by the Diesel Technology Forum.
