Interim NREL Report on In-Use Azure Balance Gasoline Hybrids in FedEx Fleet Finds Substantially Lower Tailpipe Emissions, Similar Fuel Economy to Diesels

Green Car Congress

Fuel economy was similar between the gHEVs and diesel vehicles, except for the highest kinetic intensity drive cycle where the hybrid exhibited ~20% higher fuel economy. NREL collected and analyzed data for in-use fuel economy and fuel costs, maintenance costs, total operating costs, and vehicle uptime.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency.
