Kia K4 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.

Kia’s new compact sedan replaces the oft-overlooked Kia Forte, an option that traded on value more than merit. Although the Forte provided practical packaging and decent performance (particularly in GT trim), shoppers driving home in a Forte were usually doing so because it was cheaper, rather than better, than the competition. With a revamped design and an impressive suite of standard tech, the new 2025 Kia K5 doubles down on the Forte’s fortes–particularly cargo space–while adding attractive features and retaining fuel efficiency and an affordable price tag.

Verdict: The 2025 Kia K4 is better than the outgoing Kia Forte. It offers more impressive tech, more standard safety features, more passenger space, and more cargo space. It’s still not quite as satisfying to drive as the segment leader, but with a starting price hovering around $22,000, it’s a far sight less expensive, too.
