There are those who will say that if you want to know what's coming to cars in the future, just look at the Mercedes-Benz S-Class. For decades, the flagship Mercedes-Benz sedan has ushered in tech and innovations ahead of its time, and the next-generation might be no different. As the German automaker prepares to launch the all-new model, they have given a sneak-peek of their biggest sedan.

By now though, most of us know what it looks like. A couple of months ago, the 2021 S-Class was photographed with mostly no camouflage. The teaser does confirm that the car will look much like the one spied back in May. It seems to draw heavily on the recently facelifted E-Class and current CLS. Also, the grill is wide and more upright than other Mercedes-Benz sedans in the present line-up. The upside-down hexagonal design is less pronounced here, and the headlights are less angular too.

But it's on the inside where the 2021 S-Class sees dramatic changes. It's all about screens in the next-generation S-Class as it comes with up to five of them. For this model, it seems that Mercedes-Benz is keen to have as few buttons as possible. So, what are the screens inside?

First, there's the wide instrument cluster which takes up most of the driver's area. That screen is powered by OLED, which Mercedes-Benz says uses up less power than LCD screens by 30 percent. It is also customizable and has different pre-set modes for those who want less fuss.

The second screen then takes up nearly the entire space for the center stack. It serves as the vehicle's infotainment system, but it goes beyond that. Just about everything can be controlled through that screen, from vehicle settings to the air-conditioning. Because Mercedes-Benz had removed the scroll wheel to control the infotainment system, it frees up even more space for the center console.

A pair of screens are then found behind the front seat headrests. Both those screens serve as individual infotainment systems for each of the rear passengers, meaning this car can have up to three infotainment systems on board. As for the fifth screen, it's mounted on the armrest and various vehicle functions can be controlled for back there too.

That is all Mercedes-Benz is showing in the next-generation S-Class for now. At the moment, the company hasn't mentioned when exactly the all-new model will be released. But given that teasers are starting to roll out, it might be coming in a few months, or even weeks.
