Most of the new features lie in the electronic tech the GLS 450 SUV offers in this range.
The three-row crossover is a special feature, along with the battery-aid.
"Like the smaller GLE, the GLS gets E-Active Body Control as an option. The 48-volt, battery-aided, hydropneumatic suspension gives the three-row crossover the ability to scan roads and pre-determine damping, as well as “jump” itself out of tough off-road situations like sand, mud, and rock, as seen here in this GLE video.

It has safety features second to none and that of a proper racing car. An automatic emergency braking system is one of the new standards in this SUV.
A proper family drive with all extras for fun in the sun and on the run.
