The L 566 will be one of the vehicles on display at the UK show from 28 to 30 June and will be available in Australia from July.
The model features a power-split driveline that helps minimise fuel consumption.
With an increased bucket capacity of up to 4.7m3 and a tipping load of up to 15.9 tonnes, the L 566 is said to set new standards in terms of efficiency, performance, robust design and comfort.
