The new Actros.
Only 28 litres per 100 km on average.
The last birds are in song, the leaves on the mighty riverside trees shimmer in gold and the rope ferry makes its way across the Havel in Caputh near Potsdam almost without a sound. The bold red of Emons Spedition fits perfectly into this idyll. Driver Ingo Rabenhorst has switched off the engine of his new Actros 1842 and clambered out to watch the other bank of the river approaching. These 70 metres are the most fuel-guzzling on his entire trip – but it is not his Actros that displays such a thirst here: “The ferry consumes 15 litres of diesel on its six trips every hour,” estimates ferryman Karsten Grunow.
That’s 15 litres for 420 metres. Rabenhorst’s new Actros runs on an average of 28 litres – per 100 kilometres!
Reliable and damage-free transport services.
“Our mixed fleet used to consume a good 32 litres per 100 kilometres on average,” says Willi Emons, Emons branch manager at the Grossbeeren freight traffic centre near Berlin. Founded in 1928, Emons today has a workforce of over 1950 based at 77 depots. “We are one of the few remaining medium-sized transportation companies with our own global groupage freight network,” says Ralf Wieland, manager of the subsidiary Emons Transporte GmbH. The backbone of this network is the high-frequency scheduled services between the company’s facilities. A company fleet of 150 trucks and several hundred sub-contracted trucks are in continuous operation. “Thanks to our direct access to all stops involved along our routes we are able to define our quality standards ourselves and to offer our customers particularly reliable and damage-free transport services.”
More economical than expected – thanks to sophisticated equipment.
“With some trucks clocking up a daily mileage of over 1,000 kilometres, the savings of a good four litres are a godsend. When ordering eight new Actros trucks, we opted for the fuel consumption-reducing StreamSpace cab and the Economy Pack Classic, in order to offset the additional fuel consumed by the Euro VI engine in cooling the exhaust gases,” notes Ralf Wieland.
“We hadn’t envisaged actually consuming markedly less fuel with the latest engine generation.” The Economy Pack Classic comprises aerodynamic side panelling, automatic circuit breakers, adjustable wind deflectors with cab-side extenders and the low-maintenance Compact fifth-wheel coupling.
Euro IV in-line engine as the basis for low fuel consumption.
The basis for the low fuel consumption of the new Actros trucks operated by Emons is provided by the Euro VI in-line engine with common rail high-pressure injection and the aerodynamically optimised StreamSpace cab. The Mercedes PowerShift 3 automatic gearshift exploits this potential to the full, with the support of Predictive Powertrain Control (PPC). PPC integrates a driving style adapted to the topography into the automatic gearshift system: with the aid of information from satellites, it identifies uphill or downhill gradients ahead of the vehicle and optimises shift points and cruise control speed accordingly in anticipatory manner. This can result in additional fuel savings of up to five percent.
The standard-fit radiator shutter improves aerodynamics when closed, and is opened or closed according to the engine’s cooling requirements. The electronic tyre pressure monitoring system helps to reduce rolling resistance. Optimised auxiliary consumers such as the electronic water pump also lower fuel consumption.
Exploiting the potential for savings to the full with training and fleetboard.
Ingo Rabenhorst has since arrived on the other side of the river and is headed in the direction of Werder on Berlin’s A10 orbital motorway, via which Grossbeeren is linked up to the motorway network. One of the routes from here is the daily trip to Hanover, Belzig, Luckenwalde, Fürstenwalde, Eisenhüttenstadt and back to Grossbeeren. Rabenhorst has been on the road at the wheel of the fuel-efficient Actros since October 2012.
Thanks to training by professional Mercedes-Benz instructors and FleetBoard, he is able to make good use of the saving potential offered by the new Actros. “Sometimes I even get by on as little as 26 litres per 100 kilometres,” he says.
Greater fuel efficiency is kinder on the environment, too.
Wieland sets out what the economic efficiency of the new Actros means to the company in hard figures, on the basis of the current overall annual fuel consumption for the fleet of around seven million litres of diesel. “It is only hypothetical, but if we were to switch our entire fleet over to the new, fuel-efficient Actros, we would need 500,000 litres less diesel a year.” This figure also appeals to Wieland’s strategic instincts: “Green logistics has high priority for us, as we are intent on managing the company along sustainable lines.” This includes conserving resources. ”The high resale value and the maintenance intervals optimised by FleetBoard also make the Actros an economical proposition for us,” observes the manager.
