The Natural Gas Technology (NGT) used by Mercedes-Benz is a BlueEFFICIENCY technology with extremely low exhaust emissions and a high potential for cost savings. In the bi-fuel variant you can switch over from natural gas mode to petrol mode at the touch of a button – and vice versa. Thanks to this “twin-track approach”, the drive system is suitable both for use in conurbations and for rural journeys.
It is in an urban environment that the monovalent Sprinter NGT. The petrol required for starting the engine and as emergency reserve is contained in a fuel tank of reduced dimensions (< 15 l). Switch-over is automatic and cannot be influenced by the driver. The monovalent Sprinter NGT already today complies with the most stringent European standard, the EEV (Enhanced Environmentally Friendly Vehicle) exhaust gas standards.
When it comes to fuel costs, both NGT variants are a major step ahead of the rest: CNG (Compressed Natural Gas) is around 25% less expensive in Germany, for instance, than the equivalent amount in diesel fuel (as at April 2010). Furthermore, some European countries have introduced tax concessions, incentives and other advantages, such as lower insurance premiums.
