Diesel dominance to continue in heavy-duty sector, but long-term decline likely

There can be little doubt that diesel will continue to dominate in the truck engine segment for years to come. Figures from the European Automobile Manufacturers’ Association (ACEA) show that over 2019, 97.9% of all new medium and heavy-duty trucks registered in the EU ran on the fossil fuel. The figure is very similar in the US, where 97% of on-highway Class 8 trucks are diesel-powered.
