However, they also noted, high PTW efficiencies and the moderate fueleconomies 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 fueleconomy and natural gas compressor efficiency.
In other words, they found that they real-world fueleconomy benefit of adoption of HEVs may be better than for estimates based on EPA “sticker” fueleconomy alone. Our real-world VSP-specific FCR measurements suggest computed FTP (city) cycle CV fuel use would be nearly 2 times higher than for the HEV and 1.3
Do they receive HOV access for their improved fueleconomy and ultra low emissions? In fact in 6 of the states, diesel fuel is penalized with additional state taxes. So diesel fuel gets taxed twice or penalized twice at the federal and state level. This helps us to make better fueleconomy and good emissions.
