2027 Mercedes S-Class Adds Heated Seatbelts and AI

Climb into your car on a cold morning and the seatbelt feels like a frozen rope. Mercedes wants to fix that. The 2027 Mercedes-Benz S-Class adds heated front seatbelts, plus a bigger software stack and new screens. The takeaway: focus on the stuff you’ll feel every day, and treat the “AI” talk like background noise until it proves itself.

Mercedes’ own 2027 S-Class preview calls out three real-world upgrades: heated seatbelts, Digital Vent Control that remembers your vent settings, and ENERGIZING AIR CONTROL cabin filtration. It also says the car gets MB.OS, the brand’s new operating system, and a standard MBUX Superscreen. That last part matters. Modern luxury cars live or die on how smooth the software feels.

The Comfort Upgrades Are the Best Part

Heated seatbelts sound silly until you’ve done winter commuting or early airport runs. Same with Digital Vent Control. If you share the car with a partner, you know the pain: you set the vents, they move them, and you fight about airflow for the next six months. Memory settings can end that.

The air-filtration promise is also practical. If you spend hours in traffic, a better cabin filter is not a “nice to have.” It’s quality-of-life.

Mercedes also lists the basics that buyers care about. The S 500, S 580, and S 580e stick around. The S 500 is rated at 442 hp. The S 580 jumps to 530 hp. The plug-in hybrid S 580e is rated at 576 hp with a 21.96 kWh battery. All-wheel drive is standard. So is AIRMATIC air suspension.

My Verdict

If you’re shopping an S-Class, don’t buy it for “AI.” Buy it for comfort, quiet speed, and software that won’t make you want to throw your phone out the window. Heated seatbelts and smarter climate control are the kind of upgrades you’ll notice every day.

If you’re not shopping, treat this as a preview of where Mercedes is heading. MB.OS is meant to tie infotainment and driver-assist into one updateable system. And Mercedes is already pushing city-driving assistance with MB.DRIVE ASSIST PRO. That’s the trend to watch: more help, more updates, and more features that may show up as subscriptions later.
