Why it stands out

The 2018 Mercedes-Benz S-Class stands out because it sits at the centre of Mercedes-Benz’s long tradition of using the S-Class to debut new technology and engineering ideas. In this generation, that meant a redesigned body shell that cut weight and improved rigidity, plus a move to all-LED lighting throughout the interior and exterior. It also brought a more advanced suspension setup that could scan the road ahead, along with a surround-view camera system that worked with radar and ultrasonic sensors for smoother adaptive cruise control and lane centring. The result is a large luxury sedan that feels especially serene, technically ambitious, and carefully engineered.

Inside, the 2018 Mercedes-Benz S-Class is defined by its lavish cabin and high-end equipment. The interior uses wood and metal accents, selectable ambient lighting, and a digital interface built around two 12.3-inch screens under a single panel. Many physical controls were still retained, and night vision remained available. Buyers could also find rear executive seating packages, air purifiers, active parking assist, massaging seats, Burmester surround-sound audio, and other luxury touches, although many of the best features were optional. That mix of craftsmanship and technology is a big part of the car’s appeal, especially for shoppers who want a flagship sedan that feels genuinely special.

There are trade-offs, though. The 2018 Mercedes-Benz S-Class is expensive to buy and costly to maintain, and the model’s size makes it hard to manoeuvre. It is also a complex car, so even though this generation has a very good reliability record overall, owners still need to be prepared for the possibility of expensive repairs. For buyers who value comfort, refinement, and a long list of advanced features, those drawbacks may be worth accepting.
