Advanced, efficient Euro VI technology.

The powerful, robust Arocs engines incorporate advanced, efficient Euro VI technology. Above all, they deliver the power you need for the tough jobs in construction transport and the PowerShift 3 automated gearshift boasts high driving comfort, precise gear selection, efficient power transmission and enhanced1 handling.

The particularly long-lived 6-cylinder in-line engines of the Arocs cover the performance requirements in construction transport. For optimum job matching, the fuel-efficient Euro VI engines are available in four displacement classes 7.7 l, 10.7 l, 12.8 l and 15.6 l.

The range of power outputs for the Arocs engines starts at 175 kW (238 hp) with peak torque of 1000 Nm, and culminates 18 levels higher up in the top-of-the- line engine, which produces 460 kW (625 hp) of power and impressive peak torque of 3000 Nm.

Thanks to modern Euro VI emissions technology, the cooled exhaust gas recirculation helps minimise nitrogen oxide and particulate matter during combustion. Particulate emissions are also minimised by the closed diesel particulate filter. NOx reduction is carried out using AdBlue® which, thanks to an optimised metering unit, is injected into the exhaust gas flow.

The three-stage, wear-free auxiliary brake offering up to 480 kW of brake power is optionally available for added safety. The three-stage brake system reduces wear on the service brake while enhancing safety and control of the vehicle.

Superior dynamic response, simple handling and minimized fuel consumption. The automated transmission helps ensure precise gear selection, short shift times, high driving comfort and optimal levels of economic efficiency. The PowerShift 3 applies sensitive sensor technology for gearshifting to assist with gear selection in accordance with the given driving and load situation. Overrun mode on a downhill gradient is identified and the gear is held. The crawl function with integral manoeuvring mode makes moving off easy and manoeuvring precise and responsive. Furthermore, there are various transmission modes and additional functions to make driving in construction transport easier.

With PowerShift 3, additional functions such as direct shifting from 1 to R, the rocking mode, and reverse gears with high ratios enable simple manoeuvring. The crawl function makes easy work of moving off and when the hill holder is active, this additionally facilitates pulling away on inclines.

Turbo Retarder Clutch: The optionally available Turbo Retarder Clutch ensures precise and wear-free moving off and manoeuvring with maximum traction and high braking torque, even at low vehicle speeds.

 

 

 

Depending on the intended application, “Offroad” or “Economy/power” drive programs are available. All the drive programs feature four different driving modes to master individual driving situations in an appropriate and confident manner2.

The inclination sensor is an asset in tailoring the truck to its given tasks. This sensor identifies gradients and prevents upshifting. The broad torque range enables gears to be held for longer2 in off-road terrain. That reduces the numbers of gear changes, thereby taking some of the load off the clutch and transmission.
