Powertrain

Made for the Middle East and
North Africa: a powertrain with
the ability to rise to the challenge.

The powerful, robust Arocs powertrain incorporates more than 120 years of experience. All the components, from the air intake to the turbo retarder clutch, are designed to meet the regional needs. But above all, it delivers precisely the power you need for the tough jobs in off-road transport. The complete powertrain was adjusted to meet the outstanding conditions of the Middle East and North Africa. To ensure reliability, robustness, efficiency and performance it was completely made by Mercedes-Benz.

A new dimension in high performance engines.

The new in-line 6-cylinder engines have higher engine efficiency through the wastegate turbocharger, the optimized viscous fan clutch and the intelligent auxiliary consumers.
The OM473 (Euro III), a state of the art 6-cylinder in-line 15.6 l engine opens a new dimension in high performance engines. The turbo compound unit transforms thermal energy into mechanical energy and thus increases the operating efficiency of the engine. The engine has additional power by lower fuel consumption. In addition the X-Pulse fuel-injection system reduces the fuel quantity.

Keeping it cool.

Keeping it cool.

The Arocs is equipped with an improved engine cooling system which keeps you going no matter the heat. Due to this asset the truck receives a higher engine output even to high ambient temperature or altitude. The high speed fan (OM470, 471) makes sure that the engine is protected against overheating. Another feature to ensure that the engine stays cool is the automatic down-rating of the engine in case of excessive coolant temperature.

Protection against every particle.

Dust and large particles can impede your task. For that reason the air intake was dust optimized with a cyclone air filter which collects up to 80 percent of dust and large particles inside the rubber valves. This means a reduction in maintenance cost due to reduced soiling of the paper filter and longer filter change intervals.

Meet and master all challenges with <br/>Mercedes PowerShift 3.

Meet and master all challenges with
Mercedes PowerShift 3.

The Arocs comes with Mercedes PowerShift 3 as standard and manual gearshift as an option. The gearshift is 100 percent made by Mercedes-Benz ensuring the best integration with engine and axles, providing a wider range of gears for operation in optimal torque ranges and optimized start-off capabilities. 

With Mercedes PowerShift 3 you get the best shifting strategy at any time (30-50 percent faster gear changes than manual) with friction reduction for minimized wear and tear of the driveline. Providing a wider range of gears for operation in optimal torque ranges and various driving modes for different road situations, such as Power Mode, Crawl function and Rapid Reverse.

A great variety of clutches - tailor made
for all applications.

Due to our various range of clutches we can offer the best equipment for your task to help increasing the clutch lifetime. The single plate clutch with 430 mm diameter is standard for trucks below 2,600 Nm engine power.
The dual plate clutch with 2 x 400 mm diameter is standard for trucks above 2,600 Nm engine power and your solution for heavy duty applications.
Unique in the truck world is the turbo retarder clutch for excellent start-off ability at high loads and difficult terrain without clutch overheating. The wear-free hydraulic turbo retarder clutch offers maximum stability when moving off and maneuvering with very high gross combination weights and torque levels, increasing the efficiency for high GCW and rough transport tasks. It also serves as a retarder, thus providing for additionally enhanced safety as well as reducing running costs.

A great selection of axles: <br/>meeting your demands.

A great selection of axles:
meeting your demands.

The axles on the Arocs are impressive performers in every type of operation no matter if on-road, off-road or at the construction site. The planetary axle with a load capacity of up to 16 tonnes supports at the construction site and for heavy haulage. The robust and proven planetary axles and optimized hypoid axles ensure reliable road bearing even with heavy loads.

Keeping your service brakes fresh.

Keeping your service brakes fresh.

The Arocs comes with an engine brake as a standard: Thanks to this three-stage brake system, which offers up to 230 kW of braking power, safety as well as vehicle control is increased while wear on the service brake is reduced. The engine brake uses the engine as a compressor and constant throttle to provide wear-free retardation.

In addition, a high performance, three-stage, wear-free auxiliary brake (for Euro IV/V) offering up to 475 kW of brake power is available for even greater safety, providing more opportunity to keep the service brakes fresh.

Wear and maintenance-free auxiliary brake.

Wear and maintenance-free auxiliary brake.

The secondary water retarder is available as an option and offers greater braking power (with up to 3500 Nm of braking torque), higher average downhill speeds and lower weight than conventional oil retarders. It is a wear and maintenance-free auxiliary brake that can be used to perform up to 85 percent of all braking operations.
There is no need for an additional oil circuit with oil cooler since the retarder uses the water of the engine cooling circuit.

Robustness knows no compromises.

As an all-wheel-drive semitrailer tractor, platform vehicle, concrete mixer or tipper – the Arocs covers practically all requirements. A higher frame and optimized approach and departure angles provide all Arocs trucks with high ground clearance. For a better breakover angle, diesel tanks with a smaller
cross-section are used.

The range of different front and rear axles which are available in job-specific variants are a further key contributory factor to the large ground clearance. Depending on the type of application and chassis, front axles with varying offsets and with a permissible front axle load of up to 9 t are available. The particularly robust planetary axles with a load capacity of up to 16 t also offer high ground clearance.
