SUSTAINABILITY

Optional EU Stage III and U.S. EPA Tier 3 compliant engine available.
Optional Ventilation Reduction (VR) Package, which incorporates selective engine hardware and software to reduce diesel particulate matter in the engine exhaust and deliver a significant ventilation rate reduction, a decrease in fuel consumption, and maintained or improved product performance.
Cat Diesel Particulate Filter, which complements the VR engine by further reducing particulate matter in the exhaust.
Ongoing research and development into engine compatibility with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels, plus power options like electrification.
