2018 Mercedes-Benz S Class vs. Its Competition

2018 Mercedes-Benz S450
Kirk Bell Kirk Bell Senior Editor

The Mercedes-Benz S-Class has been the luxury benchmark for good reason, and the 2018 update only improves upon its winning formula.

Still, the field of rivals is quite accomplished.

The closest rival, the BMW 7-Series, offers similar features and style, but it opts for a sportier character rather than Mercedes’ devotion to all-out luxury.

The Porsche Panamera can perform even better, and it is a technological marvel, though it is not as regal and cosseting as the Mercedes.

The Audi A8 is aging, and its interior is more stark, creating a different, less upscale aesthetic.

A new model is coming, though, and it promises to surpass the Benz in autonomous driving capability.

The Jaguar XJ is quite sporty as well, but it has never caught on with buyers to deliver the cachet of the Benz.

At the high end, the Rolls-Royce Ghost and Bentley Flying Spur are super-luxury alternatives, and they offer more traditional, somewhat ostentatious design.
