  • Low on fuel, high on efficiency.

    With fuel savings of up to 7%* compared to its already fuel-efficient predecessor, the Actros with its new 6-cylinder in-line engines is a particularly economical proposition. The engines are available in the four displacement classes 7.7 l, 10.7 l, 12.8 l and 15.6 l and in a total of 8 power output ratings from 260 kW (354 hp) to 460 kW (625 hp). The combination of low fuel consumption and improved performance is attributable to the particularly efficient combustion strategy, the X-Pulse common-rail high-pressure injection system with an injection pressure of up to 2700 bar and the patented asymmetric turbocharger. Further factors contributing to fuel savings are the more fuel-efficient auxiliary consumers, Mercedes PowerShift 3, and the sophisticated aerodynamic design.

    *The declared fuel consumption figures are determined by testing under standardised laboratory conditions. Real world fuel consumption is influenced by many additional factors such as individual driving style, load, and traffic and vehicle condition.


  • Low drag and rolling resistance.

    The design of the Actros has been optimised right down to the finest details in order to reduce wind resistance. Features such as the door extensions*, aerodynamic attachments^ and the tyre pressure monitoring^ also save fuel. In addition, the StreamSpace cab has been developed specifically for low fuel consumption.

    * Standard for cabs with level floor and 170 mm engine tunnel, not available for 320 mm engine tunnel.

    ^Optional extra.


  • Safety and assistance systems.

    Mercedes-Benz employs many safety and assistance systems to reduce risks and ease the burden on the driver*. In addition to the electronic braking system with disengageable ABS, ASR, Brake Assist, Hill Holder and Active Brake Assist 4^ which can detect the risk of collision with both stationary and moving obstacles, and crossing pedestrians below 50 kph; the high standard of safety is also supported by Stability Control Assist, Proximity Control Assist~ with stop/go functionality, Lane Keeping Assist, and Attention Assist. Standard systems such as the rain/light sensor, the co-driver mirror with a manoeuvring function and optional systems such as the bi-xenon headlamps^ and the tyre pressure monitoring system help the driver to avoid accidents.

    * The driver is responsible for the safe conduction of the vehicle.

    ^Optional extra.

    ~Optional extra in conjunction with Active Brake Assist.


  • A diverse range of cabs.

    18 cab variants in widths of 2300 mm or 2500 mm, a level floor or an engine tunnel height of 170 or 320 mm, headroom of up to 2130 mm and six roof shapes – the prime movers always able to offer a suitable cab, whatever the needs of the job in hand, day or night.

    Additionally Mercedes-Benz Trucks provides as standard an inner spring mattress*.

    *Provided in all Lcab models.


  • Your new workplace in the cab.

    Solutions geared to practical needs provided the terms of reference in developing the new workplace, resulting in a whole array of components which are finely matched on both an ergonomic and functional level. These include the new cockpit, the new seats, the new multifunction steering wheel, and the touch screen stereo with truck map navigation, Bluetooth and DVD player.

    Everything can be operated intuitively and is precisely tailored to the driver’s work procedures. The attractive colour concept, the high-quality, perfectly applied and easy-to-clean materials and the newly developed beds are further assets providing that extra touch of work motivation.

  • Good body-mounting capability.

    The frame with the consistent 50 mm hole pattern provides the basis for the prime movers high body-mounting capability. Other assets include a wide range of wheelbases, frame overhangs and end crossmembers selectable ex factory and a broad selection of tank variants. Good body-mounting capability is additionally supported by the parameterizable special module^ and pre-installations and consoles which are available ex factory.

    ^Optional extra.


  • Axles, auxiliary consumers.

    A wide choice of rear axle ratios matched to various operating profiles also plays a role in keeping fuel consumption low. Economical auxiliary consumers, such as the on-demand air compressor contribute to low fuel consumption.

There is no substitute for reliability.

A truck only earns money when it is up and running. As such, the prime requirement in the ever tougher transport business is a truck that can be counted on to operate reliably. With a service life up to 20% longer than its predecessor, the Mercedes-Benz prime mover range is a shining example of how this is achieved.

  • Reliable Engines

    All drive components of the Actros offer a particularly durable design, a high degree of reliability and an increased service life. The improved robustness of the new 6-cylinder in-line engine is the result of optimised engine cooling and design measures such as one-piece steel pistons, reinforced conrods and bearings and a more rigid crankcase.

  • MercedesPowerShift 3

    In addition to a high level of driving comfort and simple operation, the more advanced automated gearshift, which features as standard on board all prime movers, distinguishes times which are up to 20% shorter than those attainable with Mercedes PowerShift 2 and as much as 50% shorter in comparison to the Telligent® automated gearshift, in addition to which it also offers a further improvement in performance.

    Precise gear selection and fast gear-changing ensure that the further advanced Mercedes PowerShift 3 automated gearshift transmits the power spontaneously and efficiently to the rear axle. This is possible thanks to an improved shifting strategy that accounts for factors such as gross combination weight, inclination angle of the road and accelerator pedal position when selecting the optimum gear. Further benefits include the option of shifting quickly from 1 to R, reverse gears with high ratios, the crawl function and EcoRoll.

  • Clutches

    The Actros features new 1- or 2-disc clutch technology incorporating overload protection with a warning system which is designed for vast levels of torque up to 3000 Nm.


  • Rear Axles

    The weight-optimised drive axles on the prime movers boast low frictional loss and extremely smooth running. The Actros is fitted primarily with fuel-efficient hypoid drive axles for axle loads of up to 13 t. The trucks can be equipped with a further optimised planetary axle for axle loads of up to 16 t.

    Vehicle and powertrain configurations are additionally available ex factory which enable permissible gross truck and trailer weights of up to 70 t, 90 t, 120 t, or as a heavy haulage vehicle up to 250 t.


  • Brakes

    Depending on the type of application, for a high standard of safety we equip the trucks either with disc brakes, a combination of disc and drum brakes or drum brakes. In addition to the proven, electronic braking systems with disengageable ABS, ASR, Brake Assist and hill holder, powerful, wear-free engine brakes feature as standard to provide added safety. The prime movers are fitted as standard with the wear-free continuous High Performance Engine Brake*. This three-stage brake system offering up to 475 kW of brake power+ reduces wear on the service brake while enhancing safety and control of the vehicle. For even greater safety, the prime movers can be equipped with the new, high-performance secondary water retarder*. This retarder is wear- and maintenance-free and offers increased brake power, higher average speeds on downhill stretches and less weight than conventional oil retarders.

    *Optional extra. The driver is responsible for the safe conduction of the vehicle.
    + Optional extra in conjunction with Active Brake Assist.


  • Suspension Variants

    The prime movers always offers the suspension variant which is best suited to the given type of application – steel-air or full pneumatic suspension.

  • Extended Service Life

    All prime mover components come in particularly durable, repair- and maintenance-friendly design and boast a high degree of reliability. This is ensured by extensive testing at the Mercedes-Benz Development and Testing Centre in Wörth, where worldwide road conditions are simulated, enabling our trucks to be tested under the toughest conditions.

    Locally, the Actros has undertaken millions of test kilometres around Australia and New Zealand with outstanding results. The unrelenting test program also includes summer and winter trials at extreme temperatures and millions of kilometres on rough road tracks and in endurance testing. In all, the Actros has demonstrated its durability and reliability over more than 50 million test kilometres.
