Natural Gas Technology (NGT) from Mercedes-Benz is a BlueEFFICIENCY technology that delivers extremely low exhaust emissions and significant potential cost-savings. The bivalent version lets you switch the Sprinter NGT from natural-gas to petrol operation and vice versa at the push of a button. Thanks to such "duality", the drive is perfect for use in both city areas and on longer journeys out of the city.
The monovalent version of the Sprinter NGT is a natural-gas model. This single-fuel Sprinter NGT is particularly well-suited to city environments. The smaller petrol tank (< 15 litres) supplies petrol for starting the engine and as an emergency reserve only. Switching takes place automatically and cannot be activated by the driver. The monovalent Sprinter NGT already complies with the stringent EEV (Enhanced Environmentally Friendly Vehicle) emissions standard.
An analysis of fuel costs reveals that both NGT variants are ahead of the game. CNG (compressed natural gas) is around 25% less expensive in Germany, for instance, than the equivalent amount in diesel fuel (April 2011). And some European countries have introduced tax concessions, incentives and other advantages, such as lower insurance premiums.<br />
