2026 Mercedes-Benz S-Class Review: The 2026 Mercedes-Benz S-Class marks a new chapter for the brand’s luxury saloon, with 50% of the vehicle being either entirely brand new or significantly updated. Built upon a 140-year legacy that dates back to Karl Benz filing the first motor car patent in 1886, the new model combines traditional craftsmanship with a high-performance supercomputer.
The exterior preserves the classic saloon design while integrating substantial styling changes. The front features an illuminated grille that is 20% larger than the previous generation. New digital light headlamps incorporate a twin-star motif, delivering a 40% larger illumination field using micro-LED technology. These headlamps can project high-definition safety symbols, such as road work arrows or pedestrian warnings, directly onto the road surface.
Market Specifics and Exterior Highlights
For the American market, the prominent star on the bonnet can be illuminated, a feature omitted from UK models. However, British buyers receive the large, light-up exterior grille as standard. The side profile features flush, illuminated door handles that deploy automatically when pressed.
The rear of the vehicle features a distinctive triple three-pointed star design within the tail-light clusters to distinguish it from older models. The S500 variant includes visible twin exhaust pipes and a large boot capable of holding several briefcases, maintaining the shape and volume of its predecessor. Through the Manufacturer Personalization Program, buyers can choose from 150 different paint finishes, including a diamond-flecked black sparkling coat, alongside standard silver or black options.
Next-Generation Cabin Technology
Inside, the cabin features a redesigned dashboard, center console, steering wheel, and door cards. Following customer feedback, the new steering wheel incorporates physical rocker switches for cruise control and a rolling knob for volume adjustments. The dashboard features a multi-screen setup powered by a highly responsive supercomputer, which operates at speeds comparable to modern smartphones.
The infotainment system features wireless Apple CarPlay, Android Auto, and built-in apps like Disney Plus and YouTube. ChatGPT is integrated directly into the system to allow conversational voice commands, though testing revealed localized language responses, such as answering English queries in German. The passenger side receives a dedicated screen that duplicates the functions of the central display.
Advanced Driving Dynamics and Autonomous Features
Mechanically, the 2026 S-Class introduces a 4.5-degree rear-axle steering system as standard equipment to improve stability at high speeds and maneuverability in tight spaces. An optional 10-degree rear steering upgrade reduces the vehicle’s turning circle by nearly 2 meters, allowing the rear wheels to turn aggressively in reverse or forward gears.
The standard Airmatic air suspension features intelligent damping connected to the Mercedes Intelligent Cloud. When the car encounters a speed bump or pothole, it logs the precise location and uploads it to the cloud, allowing trailing Mercedes vehicles to pre-soften their suspension systems.
For driving assistance, the MB Drive Assist system utilizes:
- 12 ultrasonic sensors
- 10 external cameras
- 5 radar sensors
The system allows the vehicle to steer, accelerate, and brake unassisted. It handles automatic lane changes on motorways upon indicating and stops for traffic lights in urban areas. The advanced MB Drive Assist Pro enables fully autonomous point-to-point driving, which will deploy initially in China before expanding to the US and Europe. Furthermore, an automatic reversing assistant can steer the vehicle completely backward for up to 150 meters along its exact forward path, though it restricts speeds for safety and requires manual throttle and brake inputs.
Premium Comfort Configurations
The UK market will exclusively receive the long-wheelbase version of the saloon. Buyers can select a five-seat layout or a four-seat configuration featuring two individual first-class rear seats. The central rear armrest folds down to offer a load-through storage area or an optional refrigerator, alongside dual USB-C ports, a wireless phone charger, pop-out cup holders, and thin device slots.
Rear passengers are provided with individual entertainment screens controlled via touch inputs or two detachable smartphone-style remote controllers. The rear headrests feature a custom “140 years of innovation” emblem. When optioned fully, the seat behind the front passenger completely reclines to deploy an integrated footrest, massage programs, and localized heating.
The vehicle’s climate system introduces digital vent controls with automated direction presets for the head and body. A specialized air filtration system ionizes the cabin air to remove particles 1,200 times smaller than a grain of salt. For cold weather, the car couples its heated steering wheel and armrests with unique heated seat belts that warm up to 44°C.
Engine Lineup and Performance Testing
Globally, the S-Class is available with petrol, diesel, plug-in hybrid, six-cylinder, and eight-cylinder options. The flagship model features an upgraded V8 engine with a flat-plane crank that delivers 537 horsepower and 650 Nm of torque, though this specific powertrain is excluded from the UK market lineup.
The UK-spec S500 is powered by a refined 3.0-liter six-cylinder petrol engine producing 450 horsepower and 600 Nm of torque. It features an optimized intake camshaft, upgraded intake and exhaust ports, and a high-capacity electric auxiliary compressor. An built-in “over-torque” function temporarily boosts peak torque to 640 Nm under full acceleration. Power is delivered through a 9-speed automatic transmission designed for low-speed refinement. During top-speed evaluations on an unrestricted section of the German Autobahn, the S500 successfully reached an electronically governed top speed of 257 km/h (approximately 160 mph).
