Economical consumption combined with a tank volume of 25 kilograms (144 liters) enable a driving range of up to 530 kilometers in pure CNG operation. Opel’s ecoFLEX engines are optimized to run on natural gas, biomethane or any combination of the two, as well as gasoline.
In Germany, the government has introduced a tax benefit regulation for the use of natural gas as a fuel until 2018. This recognizes its environmental friendliness because NGVs emit up to 25 percent less CO2, up to 80 percent less nitrogen and are free of benzol and soot particles. If 100 percent biogas is used as fuel, the vehicle’s carbon footprint is almost zero.
