Driving with natural gas: NGT (natural gas technology)
In terms of both ecology and economy, natural gas drive is a viable alternative to conventional drive concepts. In comparison with conventional gasoline or diesel fuels, its advantages lie in a low-emission combustion and a less CO2-emission.
To date, natural gas vehicles still have the disadvantages of intricate fuel storage in bulky pressure cylinders and a limited filling station infrastructure. Thanks to their bivalent drive units, NGT passenger cars such as the Mercedes-Benz E 200 NGT BlueEFFICIENCY or the B 170 NGT BlueEFFICIENCY can run either on natural gas or on premium gasoline.
The Mercedes-Benz Sprinter NGT BlueEFFICIENCY with bivalent natural gas drive has been available since 2008. The Mercedes-Benz Citaro CNG is manufactured both as a solo and an articulated bus with natural gas engine. This was the first line-service urban bus with natural gas drive to comply with the EEV (Enhanced Environmentally Friendly Vehicle) exhaust standards. The Mercedes-Benz Econic NGT likewise undercuts the Euro V and EEV limits and is characterized by low noise emissions.
