Stuttgart and Burgau, Germany. October 25th 2017. Stern Auto GmbH, an authorised Mercedes-Benz sales and service outlet, has handed over the first Econic tractor unit with Euro VI natural-gas drive to Roma KG. Roma is a system manufacturer for shutters, venetian blinds and textile screens in Burgau, Bavaria. The official handover of the keys for the new Mercedes-Benz Econic NGT (Natural Gas Technology) was performed by Diether Roßmann, Centre Head for Stern Auto, to Roma’s Head of Logistics and Dispatch, Werner Riedmann.

“Environmental considerations played an important part in procurement”, said Riedmann at the vehicle handover. “Operation with natural gas enables us to realise plant traffic between the production location in Burgau and the new logistics centre in nearby Scheppach with the fewest possible emissions.”

The new 2-axle tractor unit with 18 t gross vehicle weight and a wheelbase of 3900 mm is something special from many perspectives: it is the first Mercedes-Benz Econic NGT which is approved with the highly environmentally friendly Euro VI natural-gas drive for 40 t. The Econic NGT is also an important part of Roma’s new logistics and warehouse concept. The height of the semitrailer and the ramp heights at the new logistics centre in Jettingen-Scheppach are optimally matched so that the semitrailer can be unloaded conveniently and safely both via the tail end and the side. The Econic commutes between the warehouse in Scheppach and the production plant in nearby Burgau. The drivers benefit from the Econic’s ergonomics. The low-entry concept makes the frequent climbing in and out easier, the panoramic glazing ensures outstanding vision in the busy plant traffic. The semitrailer was built at FSN-Fahrzeugtechnik in Bentwisch near Rostock.

At the heart of the Econic NGT Euro VI is the new natural-gas engine M 936 G. It is based on the turbodiesel engine OM 936 from the new “BlueEfficiency Power” generation with 7.7 litres of displacement and is operated with compressed natural gas (CNG = Compressed Natural Gas). The engine has an output of 222 kW (302 hp) at 2000 rpm, it delivers its maximum torque of 1200 Nm at 1200 to 1600 rpm and is linked to an Allison 6-speed automatic transmission.

Hardly any particulate matter, no soot particles

Unlike the diesel, the Econic NGT emits virtually no particulate matter and no soot particles. And during combustion of natural gas, 25 percent less carbon dioxide (CO2) is produced.When using biogas, the CO2 balance is even virtually neutral. Compared with diesel there are further significant reductions in exhaust emissions: some 50 percent less carbon monoxide (CO) plus 80 percent fewer hydrocarbons (HC). The natural-gas engine in the Econic NGT also works quietly and undercuts the legal requirement of 80 dB(A). It therefore also has the potential to gain quality seals for particularly quiet vehicles. Optimum prerequisites for daily use, above all in urban applications.
