3. The Intense Interest and Increased Adoption of Natural Gas
More and more fleets bought natural gas trucks in 2013 as the Cummins ISX G became available. UPS announced it was ordering 700 Class 8 vehicles powered by LNG. Dual-fuel aftermarket systems are letting fleets enjoy some of the benefits of natural gas at a lower up-front cost, with the ability to switch to diesel if you can't find a fueling station. Companies are improving natural gas tank systems to improve range and lower weight and cost. And every week, it seems, more natural gas fueling stations were opening across the country.
