Natural gas vehicles have had a mixed history in the U.S. for automakers, but GM is betting on CNG and LPG versions of 2011 Chevrolet Express and GMC Savana vans. GM listened to fleet customers and dealers about offering options to meet their business objectives, and found NGVs to have more options short term than electric vehicles for this market segment.
Background
CNG – Compressed Natural Gas
LPG – Liquefied Petroleum Gas
