Flooring it, while awesome, is especially ill-advised when the GLS is loaded up with a full complement of passengers. The 450 and 580 can comfortably squeeze up to seven people into its sturdy body, though people trying to get into that third row of seating are in for a wait. Rather than a manual fold-down mechanism, Mercedes went seats that expand and contract at the press of a button — it’s a nice touch and all, but it’s much slower than you might expect. Ultimately, that might not matter once everyone’s inside, since the GLS’s third row is heated (a first for the automaker) and packs a full complement of USB ports.

Naturally, Mercedes made sure the driver has their share of gadgets to control, too. There are up to two 12-inch displays up front — one acts as the instrument cluster while the optional extra controls climate and the infotainment system — and the GLS packs the company’s proprietary MBUX interface. In general, it’s a pleasure to use, though getting it to properly interpret voice commands can still be sort of a pain.

And let’s not forget about Mercedes-Benz’s profoundly absurd Energizing Comfort features, which can turn the inside of the GLS into a sea of tranquility by combining ambient lighting, air fragrances, music, massaging seats and climate control tweaks in different ways. Yes, it’s a little much, even for an optional add-on. Slightly more practical is the Car Wash mode that we now wish came standard on every car — it folds the GLS’s side mirrors up against the body, raises the suspension so all those water jets can clean the car’s fiddly bits, and even enables a 360-degree camera in case you want an even better view of what’s happening. In an age where automakers wage war to see who can be the most extra, Mercedes might just have a crucial leg up on the competition.
