The cloud of dust to the rear slowly settles as we turn off the engine for a short drinks break. Our eyes feast upon the generously dimensioned cockpit. Even here, it's clear why the GL successor is seen as the S-Class among SUVs: even first-class demands are met by this interior. Every fine detail of the vehicle demonstrates top-quality craftsmanship: from the high-grip, high-quality multifunction sports steering wheel in nappa leather, to the leather-covered dashboard and comfortable leather seats. The crowning glory, however, is the eight-inch colour media display of the COMAND Online system, which remains clearly legible even if the sun is shining brightly into the vehicle. It adds to the feeling of spaciousness, comfort and luxury. Speaking of spaciousness, the GLS offers masses of it: its boot has some intelligent features like a cargo position for the rear seat backrests, which take its volume up to 680 litres –an impressive maximum of 2,300 litres is even possible.
