BMW 5 Series vs Mercedes-Benz S-Class

The 2025 Mercedes-Benz S-Class is an automotive icon that fulfills its lofty expectations for comfort, performance, technology, and refinement. Last redesigned for the 2021 model year, Mercedes’ flagship sedan receives only small changes for 2025, including newly standard features like digital key functionality and a center airbag, some additional paint colors, and wider availability of the AMG Line trim package.

Verdict: Quite simply, the S-Class is the best luxury sedan that doesn't wear a Bentley or Rolls-Royce badge. With several models to choose from and a dizzying array of options, there seems to be a perfect match for a variety of tastes, provided you have a six-figure budget.

The BMW 5 Series is one of three cars that prove the country known for Autobahns, the Nürburgring, and Oktoberfest builds the best luxury sedans on the planet. It competes with the Audi A6 and Mercedes-Benz E-Class, each taking a distinct approach to design but measuring up closely in other parameters. The 2026 5 Series is virtually unchanged, entering its third year following a 2024 redesign, and this review is about the 540i xDrive model.

Verdict: Putting BMW’s love-it-or-hate-it design aside, the 2026 540i xDrive is a sensational automobile offering the right blend of luxury, technology, and performance. Choose the M Sport setup for maximum driving enjoyment, or stick with the standard specification to emphasize luxury. Either way, the styling is the most controversial thing about the 5 Series.
