2024 Kia K5 vs 2025 Mercedes-Benz S-Class

If you can overlook the real-world fuel economy and unimpressive crash-test ratings, then a 2024 Kia K5 is a steal of an automobile. (Don’t worry, it has an engine immobilizer system to prevent theft.) It comes in LXS, GT-Line, EX, and GT trim levels, and the only change for 2024 is standard heated seats for the GT-Line trim. Turbocharging is standard, and you can get all-wheel drive if you live where the sun often doesn’t shine.

Verdict: It’s a shame Kia doesn’t offer the K5 with a hybrid powertrain, and its performance in new, tougher-to-pass crash tests is worrisome. But there is no doubt the 2024 Kia K5 is a stylish, comfortable, enjoyable, and technologically advanced midsize car. And the price is undeniably nice.

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.
