It is worth mentioning that the final version of the “54.5” mpg CAFE standard for 2017-2025 was amended to add natural gas vehicles into the list of incentivized advanced-tech cars including those utilizing plug-in hybrid and all-electric plug-in technologies. This last concession was made to benefit makers of NGVs, particularly Honda. As the only automaker selling CNG cars to U.S. drivers, it had previously complained about favoritism and extra credits for hybrid pickup trucks.
“Providing incentive credits for NGVs makes a great deal of sense under this regulation. A dedicated NGV reduces CO2 emissions by 25 percent and petroleum consumption by 100 percent,” said Edward Cohen, vice president of government and industry relations of Honda. In addition, other companies that have already shown favor for the new rules include General Motors, Ford Motor, Chrysler Group LLC and Hyundai Motor Co.
