All projections are estimates based on user-supplied inputs and certified independent engine test results (Olson-Ecologic Engine Testing Laboratories, SAE Supplemental Emission Test (SET) Protocol, Cummins ISM 400, Serial No. 60412072). Test IDs: HNOHYDSET032213_04 (baseline, without LeefH2™) and HNOSETHYD040513_01 (with LeefH2™). Fuel consumption figures per engine type are industry reference estimates and may vary.
