Mercedes-Benz S-Class

Model Overview

The Mercedes-Benz S-Class is the flagship full-size luxury saloon under the Mercedes-Benz brand. Since its debut in 1951, it has consistently stood as the benchmark in the global full-size luxury limousine segment and an industry pioneer in technological innovation. In the domestic market, the S-Class is sold as a fully imported (CBU) model. In February 2025, the 2025 S-Class was launched with pricing ranging from RM962,600 to RM2,042,600. In October 2025, the 2026 annual facelift model was officially launched, carrying an official recommended retail price ranging from RM898,800 to RM2,042,600. In January 2026, the all-new generation S-Class (W223 facelift) was officially unveiled with over 2,700 re-engineered components—making up more than half of the vehicle—which the manufacturer defined as a "reconstruction of underlying logic". The car made its domestic debut at the Beijing Auto Show in April 2026. Key rivals to the S-Class include the BMW 7 Series and the Audi A8L.

Design Language

The 2026 S-Class carries forward Mercedes-Benz's "Sensual Purity 2.0" design philosophy, sculpting an exclusive geometric aesthetic with clean, flowing lines and contoured surfaces. Up front, it sports a large shield grille alongside the iconic standing three-pointed star bonnet emblem, exuding an imposing presence. The all-new generation model unveiled in January 2026 further enlarges the grille (by approximately 20%), increases the horizontal chrome louvres from three to four, and introduces an active illuminated function, with the standing bonnet star also gaining illumination. The headlamps have been upgraded to the next-generation "twin star" Digital Light units powered by micro-LED technology, extending illumination range by around 40%, with the ULTRA RANGE high beam reaching up to 600 metres.

Dimensions-wise, the long-wheelbase version measures 5,290 mm to 5,320 mm in length (extended to 5,304 mm for the all-new generation), 1,921 mm in width, and 1,503 mm in height, with a generous 3,216 mm wheelbase. The vehicle boasts a remarkably low drag coefficient of 0.22 Cd. Round the back, it features two-piece tail lamps styled with a "lake reflection" motif, crafted from multi-faceted 3D diamond-cut light pillars. Power-closing soft-close doors and dynamic star puddle lamps come standard across the range.

Inside, the S-Class embraces a yacht-inspired wraparound cabin concept, featuring a flowing bridge-style wood trim dashboard accented with Nappa leather and delicate contrast stitching. The 2026 line-up comes standard with a 12.3-inch glasses-free 3D digital instrument cluster and a 12.8-inch OLED central touchscreen. The all-new generation model steps it up with the MBUX Superscreen setup, comprising a 14.4-inch central display, a 12.3-inch driver display, and a 12.3-inch front passenger display.

Powertrain & Performance

The 2026 Mercedes-Benz S-Class range is exclusively powered by straight-six turbocharged petrol engines paired with a 48V integrated starter-generator (ISG) mild-hybrid system, mated to a 9-speed automatic transmission (9G-TRONIC) . It is offered in three output tunes:

• S 400 L: Powered by a 2.5-litre turbocharged straight-six engine producing 230 kW and 450 Nm of torque.

• S 450 L 4MATIC: Powered by a higher-output 2.5-litre turbocharged straight-six engine churning out 270 kW and 500 Nm of torque, completing the 0-100 km/h century sprint in 5.6 seconds.

• S 500 L 4MATIC: Powered by a 3.0-litre turbocharged straight-six engine kicking out 330 kW and 560 Nm of torque.

The all-new generation S-Class further upgrades its powertrain line-up: the S 500 4MATIC gets the M256 Evo straight-six engine pushing out 330 kW (449 hp) and 600 Nm of torque; the S 580 4MATIC features the M177 Evo V8 mill churning out 395 kW (537 hp) and 750 Nm of torque. Meanwhile, the revered V12 engine remains exclusively available on the Maybach S 680.

Chassis & Handling

Underneath, the S-Class employs front and rear multi-link independent suspension, with AIRMATIC air suspension fitted as standard across the range. On the 2026 all-new generation model, the air suspension is deeply integrated with the Magic Body Control system, reading road surface conditions ahead via real-time cloud data to deliver damping responses faster than human nerve reflexes. Rear-axle steering provides up to 10 degrees of angle, dramatically tightening the turning circle of this 5.3-metre-plus flagship saloon. In terms of drivetrain configurations, the S 400 L is rear-wheel drive, while the S 450 L 4MATIC and S 500 L 4MATIC are equipped with the 4MATIC permanent all-wheel drive system. The top and second-to-top variants come standard with the AMG Line styling kit, with wheel options available in 19-inch and 20-inch sizes.

Cabin & Equipment

On the digital front, the S-Class runs on the third-generation MBUX infotainment system powered by the flagship Qualcomm Snapdragon 8295 chipset. The 2026 model supports a six-screen ecosystem—comprising the 12.3-inch glasses-free 3D instrument cluster, 12.8-inch OLED central screen, and dual 11.6-inch rear seat entertainment displays. The voice assistant supports rear-passenger voice prompts, while the MBUX Interior Assistant uses overhead cameras to track passenger gestures, predicting and triggering over 20 functions. The all-new generation model introduces a built-in virtual assistant capable of schedule management and emotion recognition.

Audiophiles are treated to a Burmester® High-End 4D Surround Sound System with 31 speakers and 8 seat exciters, integrated with Dolby Atmos technology. The cabin is lined with Nappa leather seats equipped with heating, ventilation, and memory functions for both front and rear rows. Seats in the all-new generation model incorporate 19 precision motors to deliver hot-stone massage programmes.

Equipment specifications have been slightly revised for the 2026 model year: the newly introduced entry-level S 400 L Special Edition foregoes features like rear automatic climate control and the "Air Balance 3.0" air purification system found on the S 400 L Business Edition; the S 450 L 4MATIC gains Active Ambient Lighting as standard, while the MBUX High-End Rear Entertainment System moves from standard to optional equipment.

Safety & ADAS

Advanced Driver Assistance Systems (ADAS) have been a primary upgrade focus for the S-Class in recent years. From the 2025 model year onwards, the S-Class comes standard across the range with an L2+ Navigation-Guided Pilot Assist system, capable of autonomous lane changes, overtaking, and heavy-vehicle avoidance on highways and urban expressways. Over 40 intelligent driver assistance functions are packed into the vehicle.

The 2026 all-new generation S-Class takes active safety a step further, deploying 17 sensor units across the car, including high-definition cameras, millimetre-wave radars, and ultrasonic sensors. It comes equipped with the China-exclusive MB.DRIVE Navigation Assist system supporting urban and highway Navigate on Autopilot (NOA). Notably, this system was jointly developed by Mercedes-Benz and Chinese autonomous tech firm Momenta. In February 2026, German Chancellor Friedrich Merz experienced the next-generation S-Class in Beijing and spoke highly of its urban and highway pilot assist capabilities.

On the passive safety front, the all-new generation S-Class is fitted with 15 airbags, debuting two world-first innovations: rear frontal airbags that deploy with the same protection logic as front units, and inflatable beltbags that triple the load-bearing surface area across the occupant's chest upon deployment. The electronic architecture transitions to Mercedes-Benz's proprietary MB.OS operating system, seamlessly integrating ADAS, smart cockpit, and vehicle dynamics domains.

Market Performance & Verdict

The Mercedes-Benz S-Class has long held a commanding presence in the full-size luxury saloon market in China. In 2024, its annual sales remained among the top contenders in the German D-segment luxury class. However, market dynamics have shifted considerably in recent times, with global S-Class production falling from 90,000 units in 2022 to under 50,000 units in 2025. In January 2026, S-Class sales stood at 1,005 units. At the same time, high-end Chinese new energy vehicles—led by the MAEXTRO S800—have rapidly gained traction in the million-yuan tier, presenting a direct challenge to legacy luxury marques.

Media commentary notes that the S-Class's enduring appeal lies in the sheer prestige of the three-pointed star, the peerless opulence of its yacht-inspired cabin, and its supremely plush, composed ride quality. With its extensive overhaul of over 2,700 parts, the 2026 all-new generation S-Class delivers a systematic evolution across intelligent driving, digital cockpit tech, and chassis dynamics. Pundits suggest that the S-Class is effectively pivoting from traditional "mechanical luxury" into a new paradigm of "tech-driven luxury". As the undisputed crown jewel of automotive engineering, striking the right balance between timeless heritage and disruptive tech will be crucial for the S-Class to continue setting the benchmark for flagship luxury limousines in the new era.
