Exterior design

The exterior design of the W223 S-Class is smoother and cleaner than the previous generation. The proportions are impressive, especially in the Lunga version (V223), with an extended wheelbase and elegant lines, without excess. The Digital Light headlights, the massive front grille and the characteristic rear light underline the top-of-the-range status.

In the Maybach version, the focus falls on chrome, exclusive details and an imposing visual presence, without becoming aggressive.

Interior design and technology

The interior is, without exaggeration, among the most advanced in the industry:

• large vertical central OLED screen
• New generation MBUX system, very fast and customizable
• complex ambient lighting, integrated into assistance systems
• seats with advanced massage, ventilation and well-being functions
• premium materials: fine leather, natural wood, real metal inserts

The Long and Maybach versions highlight the rear seats, with functions worthy of a business class airplane.

Performance and behavior on the road

Despite being a limousine over 5 meters long, the S-Class impresses with:

• stability at high speeds
• exceptional sound insulation
• precise size direction
• pneumatic suspension that absorbs shocks perfectly

The V8 and AMG versions offer authentic sports performance, without compromising comfort.
