Mercedes is refreshing its luxury performance sedan, and we're looking at more than just updated body panels. The 2026 AMG S63, which we just spotted testing with camouflage, features exciting but under-the-radar exterior changes, new lighting elements, and even some clever new software expected to be under the hood. It's still every bit the luxury animal we expect, but with more glitter and digital glamour. Here is a general and friendly overview of what's changed (and what's not) on this flagship sedan.
What's the deal with the starry lights?
Mercedes is sprinkling some Hollywood flare onto the new S63, and appears to have a starstruck sensibility with star shape daytime running lights (DRLs). These luminous designs now appear on the headlights and taillights, which make the sedan glimmer even when parked. It is a cool design narrative that began with the E-Class, and is now furthering itself across the line-up. Not only do the new lighting elements increase the car's on-road presence but provide a visual signature, rendering it somewhat unique from the other ¨hot¨ luxury sedans on the road—especially at nighttime. Look for this to be an eye-catching option in Beverly Hills traffic.
Still packs a punch: 791-hp hybrid V8 !
If you are an AMG fan, there is some good news right away—Mercedes isn’t messing with the recipe, at least not too much. The new S63 is expected to have the current 4.0-liter twin-turbo V8 plug-in hybrid under the hood, which produces a mind-numbing 791 horsepower and over 1,000 lb-ft of torque. That’s exotics class performance in a four-door tuxedo. You get neck-wrenching acceleration with plenty of torque you can employ to bum your way through traffic, or hit the floor and see how quickly you launch off the line! With a slight EV-only range you can afford to put around in the city without any noise at all from the engine compartment.
The interior may stay modern, but be smarter
Although the cabin on the test vehicle is secured, we understand that Mercedes wanted to bring MBUX products on board and maybe even the Hyperscreen— a full-dash open screen that looks like an alien sci-fi feature. Look for smarter voice commands further-detail personalization, and quicker responsiveness. This is an improvement that should not necessarily look dramatic but will be more fluid and intuitive the next time you drive or fiddle around with the navigation screen. Comfort and digital luxuries were always part of what gives the S-Class that feeling of a moving lounge.
Is it going to be self-driving jury?
Mercedes introduced Drive Pilot, a semi- autonomous Level 3 driving system. The facelifted S63 could receive an improved version. This might equal more reliable hands-off driving under certain conditions, like low-speed highway traffic. The regulations in the U.S. are very limited still only allowing drivers to use their hands off the wheel under a few conditions, and the tech is changing quickly. You might soon find yourself, allowing the car to deal with the stress while you let your hair down—if only for just a bit. Expect slow, and practical improvements now, and not crazy autopilot movies yet. The interior may very well remain the same however if there are incremental improvements, it will make it easier to enjoy the ride.
Changes on the exterior are minor but sharp
To the eye of the untrained observer, this facelifted S63 won't scream "new model," but the devil's in the details. The grille appears a little wider and more aggressive, the air intakes are reshaped, and the bumpers look tighter and more svelte. All of this, combined with those new DRLs and likely new wheel designs, gives the car a sharper, cleaner look. In a way, it's like your buddy who you see every few months with a new haircut, and they've suddenly lost five years of age. You notice it, but you cannot explain why.
When can you buy it in the U.S.?
Given the stage of the prototypes, we expect Mercedes to formally unveil the new S63 sometime in 2025, as a 2026 model year vehicle. Production and U.S. deliveries will occur shortly thereafter. Given how polished the prototype is already, they may even be in dealer lots before 2026. If you shop at the ultra-luxury performance price point, it's worth a wait on the S63.
