Liebherr Efficiency+ for wheeled excavators


Liebherr diesel engines set the standard for fuel consumption in their power class. They boast excellent fuel efficiency, long service and high torque. Maximum power is produced even at low revs. The result is less stress on the components while maximum performance is retained, and the lower engine speed reduces fuel consumption.

Key components such as the diesel engine, hydraulic components, electronics components, slewing ring and swivelling drive are developed and produced by Liebherr itself. The great depth of in-house manufacturing guarantees maximum quality and provides for optimal configuration of components.

A variety of preset modes allows the driver to adapt the performance of the machine quickly and easily to the requirements of each workstation.

S (Sensitive):

For especially sensitive work or for lifting loads

E (ECO):

For especially economical and eco-friendly work


For high handling capacity and heavy loads.

In addition, the engine speed can be freely adjusted to the operating conditions with a rotary switch.

One new feature is the special drive mode, which makes the full engine output available for the travel drive. This provides for better acceleration and road performance, especially uphill, while at the same time reducing fuel consumption.

Automatic idling function

The standard automatic idling function reduces the engine speed to idle if no hydraulic function is activated for a few seconds. Proximity sensors in the joystick levers restore the original engine speed as soon as the driver's hand is moved towards the lever again.

This ensures that the set engine speed is available as soon as the lever is touched. The result is a combination of fuel saving and reduced noise levels. Operating costs can be reduced even further with the optional automatic engine cut-off function.
