Earlier sightings of regular GLEs showed a new nose design, which despite being camouflaged appears to have a more prominent bonnet and new headlights.
Fewer changes are expected for the car's grille, as the one fitted to test cars look identical to the current model's, with a pair of horizontal slats and large Mercedes-Benz badge in the middle.
The most prominent change elsewhere is the fitment of new wheel arch lips, which give the car a more rugged stance and suggest its track could be slightly wider.
The car's overall wheelbase could be longer too, as the test car looks to have a shorter front overhang.
At the rear, the window is more raked than the current model, and it's safe to assume the design of the tail-lights has also been changed.
As for powertrains for the non-AMG range, an updated list of turbocharged four- and six-cylinder petrol and diesel engines, as well as a new hybrid option, are expected.
