Two new Freightliner Cascadia compressed natural gas (CNG) vehicles will be showcased for the first time by Daimler Trucks North America. One of the new Cascadia CNG vehicles was developed in collaboration with UPS. The new Cascadia day cab is equipped with a Cummins Westport ISX12N Near Zero (NZ) NOx natural gas engine and Eaton Fuller Advantage Series automated manual transmission, which, when combined with the model’s aerodynamic design, can result in fuel efficiency gains of up to 3% compared to similarly spec’d original Cascadia CNG truck models, the company said.
The ISX12N meets the California Air Resources Board Low NOx standard of 0.02g/bhb-hr, a 90% reduction from engines operating at current U.S. Environmental Protection Agency (EPA) NOx limit of 0.2 g/bhb-hr.
The other new CNG vehicle is a Freightliner M2 112 equipped with a Cummins Westport L9N Near Zero NOx natural gas engine and TYMCO sweeper. Also among Daimler’s alternative fuel options are the propane-autogas S2G chassis from Freightliner Custom Chassis Corp., and the Thomas Built Buses (TBB) Saf-T-Liner C2 all-electric school bus.
