When Mercedes‑Benz unveiled the 2026 S‑Class, it was clear that this was no ordinary facelift. Engineers replaced or refined more than 2,700 components, meaning over half of the vehicle is new. The changes begin on the outside: a 20 percent larger grille filled with hot‑stamped chrome stars projects a grander presence, while the traditional hood ornament now illuminates as part of the car’s striking light signature. Mercedes’ trademark three‑pointed star motif also appears in the headlights and taillights, underscoring the brand identity with refined opulence. Optional 20‑inch cross‑spoke wheels use high‑pressure casting to reduce weight and material consumption, and customers can choose from more than 150 paint colours.
Digital light and starry illumination
Lighting technology takes centre stage on the facelifted S‑Class. New micro‑LED Digital Light headlamps cut energy consumption in half while offering ultra‑range high beams that illuminate up to 600 metres ahead. The headlamps and taillamps embed miniature three‑pointed stars in their lenses, and the lights can project patterns such as welcome animations or warnings for oncoming drivers. These lamps are paired with a 20 percent larger grille outlined by a luminous frame and an illuminated bonnet star. At the rear, triple‑pod taillights with a star pattern and chrome accents contribute to a wider stance.
An interior defined by screens and AI
Inside, the S‑Class adopts the MBUX Superscreen architecture. A 14.4‑inch central display is flanked by twin 12.3‑inch screens—one for the driver and another for the front passenger—forming a sweeping glass surface. Rear passengers enjoy two 13.1‑inch high‑definition displays with built‑in cameras. Mercedes’ latest software platform, MB.OS, underpins the cabin: it unifies navigation, vehicle systems and voice assistants. Generative AI powers the “Hey Mercedes” virtual assistant, enabling complex dialogue through voice assistants based on ChatGPT‑4o and Google Gemini. Navigation relies on Google Maps‑based data to provide real‑time traffic and 3‑D surroundings. Even the air vents are electronically controlled through Digital Vent Control, and an updated Energizing Air Control system filters cabin air for maximum purity.
Comfort innovations
Although the cabin brims with screens, Mercedes preserved its luxurious ambience. Heated seatbelts can warm occupants to 44 °C (111 °F), while detachable remote controls allow rear passengers to adjust seat functions, climate and entertainment. The expanded Manufaktur programme offers nearly 50 bespoke paint finishes and 25 leather options, emphasising individuality. The interior retains high‑quality materials and adds Digital Vent Control for precise airflow. Mercedes has also equipped up to 10 external cameras, five radar sensors and twelve ultrasonic sensors, enabling advanced driver assistance and environment awareness.
Handling and suspension
The 2026 S‑Class comes standard with rear‑wheel steering that turns the rear wheels up to 4.5 degrees, reducing the turning circle by nearly two metres. Buyers can upgrade to an optional 10‑degree system for even tighter manoeuvrability. E‑Active Body Control, an active suspension that reads the road ahead, uses cloud‑sourced Car‑to‑X data to adjust damping at each wheel and can lift the car within milliseconds to mitigate side‑impact forces. This predictive suspension works alongside AIRMATIC air springs and electronically controlled dampers, delivering a blend of comfort and agility.
Engines and electrification
Mercedes offers a broad powertrain portfolio, all featuring a 17 kW integrated starter generator and a 48‑volt mild‑hybrid system. The M256 Evo 3.0‑litre inline‑six petrol engine increases torque to 600 Nm, with a temporary overtorque function lifting output to 640 Nm. The OM656 Evo diesel introduces an industry‑first electrically heated catalytic converter to reach optimal operating temperature more quickly, reducing cold‑start emissions. For enthusiasts, the M177 Evo 4.0‑litre V8 now uses a flat‑plane crankshaft, producing 537 hp and 750 Nm of torque while promising smoother, quieter operation. A plug‑in hybrid version pairs the six‑cylinder petrol engine with an electric motor to deliver up to 577 hp and 750 Nm and offers an electric‑only range exceeding 100 km.
Safety and lighting technology
Safety remains central to the S‑Class ethos. The MB Drive Assist Pro system uses the vehicle’s cameras, radar and ultrasonic sensors to support highly automated driving, with China receiving the feature first. The updated model includes PRE‑SAFE® Impulse seat belt pretensioners, dual‑stage airbag inflators, and up to 15 airbags, including a rear airbag designed to reduce head and neck loads during severe frontal impacts. Digital Light technology adds functions like lane‑construction guidance, cold‑weather warnings that project snowflake symbols onto the road, and improved construction‑zone lighting. This technology was refined in a state‑of‑the‑art light tunnel over 100 metres long, enabling Mercedes to simulate real‑world conditions.
Balancing heritage and innovation
The 2026 S‑Class demonstrates Mercedes‑Benz’s ability to merge tradition with cutting‑edge technology. While its star‑embellished grille and illuminated emblem celebrate heritage, the adoption of MB.OS, generative AI and predictive suspension systems signal a bold future. By revising more than half of its parts, enhancing powertrains to meet Euro 7 standards, and expanding digital and safety features, the facelifted S‑Class reasserts itself as the benchmark for luxury sedans. In an era when SUVs dominate and competition intensifies, Mercedes’ flagship proves that continuous innovation, coupled with artisanal craftsmanship, can keep a sedan at the pinnacle of automotive excellence.
