Low costs. Right from the outset and throughout the truck’s entire useful life. With innovative, fuel-saving technology, low repair and maintenance costs, high residual values and attractive leasing and financing conditions which also contribute to the vehicle’s efficiency.
Achieving low operating costs with a focus on reduced fuel consumption is the first pillar of RoadEfficiency - and a promise we have continued to keep over the years. For example as the first manufacturer to introduce the fuel-efficient Euro VI engines. Or with Predictive Powertrain Control* **, a system which is capable of saving up to 5% more diesel. In short, innovative technology that has continued to set new standards.
The Actros continues to underline its leading role: in over 2000 Fuel Challenges it has won more than 90% – with a consumption advantage of around 10%***. But that’s not all: in future we will continue to work on lowering consumption – further reducing total costs in the process.
The Actros battling in the Fuel Duel. Which is the more economical drive?
Which is the more economical in everyday haulage operations? Mercedes-Benz was determined to find out – and has sent the Actros out hundreds of times to different haulage companies to do battle in “Fuel Duels” against the competition.

With the modified OM 470 and OM 471 the range now features two even more economical engines, each of which is available in five power output ratings.
Other contributing factors to the low fuel consumption include the optimised 12-speed transmission, the improved shift strategy and Predictive Powertrain Control* **. New, intelligent ancillary consumers and honed aerodynamics also play a role. In conjunction with the optimised powertrain, the new OM 470 and OM 471 engines are, all in all, able to achieve fuel savings of up to 6% in comparison with their predecessors.
Topography-oriented driving style.
Predictive Powertrain Control* uses digital 3D road maps and GPS information to generate an electronic horizon which is employed to optimise shift points, gear selection and the set cruise control speed in anticipatory mode. In this way, a driving style adapted to the given topography which will generally be beyond the capabilities even of experienced drivers can be integrated into the automated system, resulting in additional fuel savings of up to 5%.

In order to avoid shifting on an incline as far as possible, PPC performs the shift – if beneficial – before the start of the climb and/or increases the speed within the upper limit of the hysteresis range. Predictive Powertrain Control§1 additionally provides for an optimised shift sequence, e.g. fewer gear changes and larger gear steps.
Why accelerate when coasting is sufficient? The kinetic energy of the vehicle is continuously determined. In other words: the vehicle automatically detects if it can attain the set cruise control speed quickly enough by coasting. What's more, EcoRoll can be used to avoid engine drag losses.
The principle centres on coasting over the brows of hills to avoid braking on downhill stretches. The kinetic energy of the vehicle is continuously determined. This enables the vehicle to assess in good time whether it can coast over the brow of the hill at adequate speed. EcoRoll can be used to reduce engine drag losses.
As a result of precise activation, Predictive Powertrain Control§1 is able to make optimum use of EcoRoll phases. This means that EcoRoll saves fuel not only on virtually level stretches, but also ahead of hilltops, for example. In addition, EcoRoll phases of under 10 seconds can be avoided in valleys, for example.
The system helps promote a reduced-consumption, reduced-wear driving style. To this end, it records and analyses technical data from the truck. The driver’s style of driving is assessed on the basis of this data and a corresponding mark is awarded. This allows objective assessment and individual driver training. FleetBoard Performance Analysis* also ensures that the driver continues to adhere to the reduced-consumption driving style learned during Mercedes-Benz EcoTraining. This can result in long-term fuel savings of up to 15%.
