Mercedes-Benz Commercial Vehicles: Through the city on electric power
As one of the world's leading manufacturers of trucks and buses, Daimler has always set a strong example when it comes to ecofriendly innovations. With commercial vehicles it's always about ensuring a perfect match between two things: economy and ecology. This results in the development of a wealth of technologies that must prove themselves on a daily basis: from the battery-electric-powered Fuso Canter E-Cell light-duty truck to gas-driven buses, a range of hybrid vehicles and the Actros heavy-duty truck with a highly efficient diesel engine.
The electrically powered Fuso Canter E-Cell light-duty truck has been in commercial fleet testing since 2015. Initially in Portugal, its country of production, a total of five of these vehicles have now also been on the road for Stuttgart city council and the logistics company Hermes since April of this year. In place of a diesel engine, an electric powertrain with a powerful permanent-magnet motor delivers 110 kW (150 hp) of power to the rear axle via a single-speed transmission. Available from the very first second of operation, a torque of 650 Nm gives the six-tonne truck almost the same acceleration as a passenger car. As with all vehicles in this weight category, the top speed of the Canter E-Cell is limited to 90 km/h. The batteries weighing around 600 kg allow ranges of over 100 kilometres, thus exceeding the daily distance covered by many light-duty trucks used for short-radius distribution.
Citaro NGT world premiere: climate-neutral transport with bio natural gas
Daimler Buses unveiled the new natural-gas-driven Mercedes-Benz Citaro NGT urban bus in 2015. Featuring the newly developed M 936 G gas engine, it has become a benchmark for natural-gas buses. The Citaro NGT is 20 percent more efficient than its predecessor. Furthermore, it is practically CO2-neutral if bio natural gas is used. It easily meets the extremely strict Euro VI emissions requirements in many cases. And it does this without the need for the diesel engine's familiar SCR technology with AdBlue injection or a particulate filter thanks to practically particulate-free combustion.
Western Europe's urban-bus market amounts to around 10,500 new registrations a year on average and remains steady at this level. The highly specialised European segment for urban buses with natural-gas engines currently accounts for just under 1000 units a year. Daimler Buses expects this number to keep rising in future because of environmental projects in urban areas.
As an alternative to the further optimised drive system with internal combustion engine, the next stops en route to the future are the Citaro E-CELL and Citaro F-CELL. Both are based on a shared E-Mobility platform. On this basis, Daimler Buses is expecting the production version of the battery-electric-powered Citaro E-CELL to start hitting the road in 2018. In this development work, Daimler Buses benefits from its integral position within the Group as all the vehicle divisions are working closely together on the road to locally emission-free driving. Bundling of research work is therefore possible here. Certain components such as the fuel cell stacks can also be used in cars and commercial vehicles alike.
Fuso Canter Eco Hybrid: no 7.5-tonne vehicle is more frugal or has a higher load rating
The Fuso Canter with hybrid drive has been in production in Portugal since October 2012. Its fuel consumption is up to 23 percent lower than that of the conventional Canter model. From this comes the highly sophisticated four-cylinder turbo diesel with a displacement of 3.0 l, an output of 110 kW (150 hp) and a maximum torque of 370 Nm. The BlueTec 6 engine meets the requirements of the Euro VI emissions standard. Its emission control system combines exhaust gas recirculation, SCR engine technology with AdBlue injection and a particulate filter. The electric motor, with an output of 40 kW and a maximum torque of 200 Nm, obtains its energy from lithium-ion batteries. They provide a capacity of 2 Ah and weigh just 63.5 kg. The additional weight resulting from the hybrid drive amounts to only around 150 kg. This means a load capacity of up to 4.8 t for the 7.5-tonne model as a chassis with cab.
Mercedes-Benz Actros: economy and ecology in perfect harmony
Never before has a long-haul truck been as systematically designed for maximum efficiency as the Mercedes-Benz Actros. It stands for the ultimate in economy in the tough transport business. With the introduction of the latest-generation OM 471 heavy-duty engine, the already low fuel consumption is further reduced by up to three percent. This is not only good for the company's bank balance, it also preserves resources: assuming an annual mileage of 130,000 km in long-haul transport and a consumption of approx. 28.5 litres/100 km on a demanding route covered at full load capacity, every single Mercedes-Benz Actros with the latest-generation OM 471 engine would save around 1,100 litres of fuel a year. This is equivalent to a reduction in CO2 emissions of around three tonnes for every single truck. Businesses benefit first and foremost from the low costs: low fuel and oil consumption, extremely long maintenance intervals of up to 150,000 km, as well as the engines' robust and durable qualities.
This is largely thanks to the state-of-the-art technology in the six-cylinder in-line engine with a displacement of 12.8 l, an output of 390 kW (530 hp) and a torque of up to 2,600 Nm: two overhead composite camshafts, the unique common-rail injection system with X-Pulse pressure booster, the asymmetric exhaust gas turbocharger, the powerful engine brake and emission control with SCR technology, exhaust gas recirculation and particulate filter to meet the requirements of the strict Euro VI emissions standard.
