Green Car Journal is preparing to announce its Green Car of the Year at the upcoming Los Angeles Auto Show in November and has officially revealed its five finalists. Among them is Chevrolet’s 2015 Impala CNG, which has a flex fuel system allowing the full-size sedan to run on both normal gasoline and compressed natural gas.

The Impala CNG is available only with a 3.6-liter V6 engine, which has been upgraded with hardened valves and valve seats to accommodate the use of CNG. The CNG tank is stored in the trunk and provides about 150 miles of range. Chevrolet says CNG is not only much friendlier to the environment than gasoline, but can provide savings of up to $1.25 a gallon.
