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. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. —Curran et al.

Center for Automotive Research calls long-run economic risk to auto industry of mandating permanent fuel economy standards very serious; recommends periodic reviews

Green Car Congress

Plug-in hybrids dominate market penetration in 2025 under CAR scenario IV (62 mpg CAFE standard). The CAR report, the US Automotive Market and Industry in 2025 , relies on technology and market forecast data from the National Research Council (NRC) and J.D. CAR researchers used the four fuel economy scenarios developed by.
