NGVs are an ideal alternative for light trucks: Pickups and other light trucks account for over 50% of light-duty vehicle sales, but there are not expected to be any electric pickups for the foreseeable future due to the weight and cost added by battery systems. By contrast, NGVs are a proven low-emission alternative for pickups, and leading NGV manufacturers are pursuing engine designs to yield even lower emissions and greater efficiency by taking advantage of the high-octane, clean-burning properties of CNG.
