NGT stands for Natural Gas Technology and refers to BlueEFFICIENCY vehicles which are able to run in economical, low-emission natural gas mode or alternatively on lead-free premium-grade petrol.

"NGT" stands for Natural Gas Technology. Among the BlueEFFICIENCY models from Mercedes-Benz the term indicates the passenger cars with bivalent natural gas drives in which the driver has the choice of running the vehicle on natural gas or lead-free premium-grade petrol. The driver can switch between these two alternatives at the flick of a switch – an electronic control unit provides for a gentle, jolt-free changeover. The good performance and torque characteristics of the Mercedes-Benz engines are fully retained in natural gas mode. Natural gas vehicles are an important element of Daimler's overall sustainable mobility concept aimed at reducing fuel consumption and CO2 emissions. In natural gas mode, carbon dioxide emissions fall by more than 20% on average in comparison to engines running on petrol. And running on natural gas is not only ecological, but economical, too. When natural gas consumption is converted to the energy equivalent for petrol, the price per kilometre is around 50% below the fuel costs for a trip with the engine running on petrol.

Natural gas can be used in its natural state as a primary energy source, thus avoiding any conversion losses. It is non-toxic, odourless and consists primarily of methane (CH4), making it the fossil fuel with the lowest carbon content. This results in a reduction in CO2 emissions of around 20% in comparison to petrol. Development of the refuelling station network in Germany is proceeding apace, with natural gas currently available at more than 730 stations. Refuelling with natural gas is an absolutely simple process and hardly takes any longer than with traditional fuels. Furthermore, refuelling with natural gas does not entail any evaporation losses or unpleasant smells. As natural gas is lighter than air, natural gas vehicles are not subject to any access restrictions in multi-storey car parks or tunnels. Signs such as "No access for compressed-gas motor vehicles" do not apply to natural gas vehicles.
