2023 Mercedes-Benz CLS: What's New, Specs & Features
Last updated August 4, 2026
The 2023 Mercedes-Benz CLS is a true carryover with no major product changes. It keeps the same single-trim CLS 450 4MATIC lineup and facelifted design introduced for 2022.
About the 2023 Mercedes-Benz CLS
3rd generation CLS (C257), introduced for 2019; 2023 is the facelifted final U.S. model year.
Mercedes-Benz positions the CLS as a style-first luxury sedan with coupe-like proportions, not as the roomiest or most overtly sporty choice in the brand’s range. The core appeal is its sweeping 4-door-coupe shape, smooth six-cylinder power, standard all-wheel drive, and upscale cabin tech. For most shoppers, the CLS is the Mercedes for getting E-Class comfort and sophistication in a more dramatic, fashion-forward body.
For 2023, the CLS is a sleek four-door luxury car focused more on comfort and design than aggressive performance. The sole CLS 450 4MATIC has a 362-hp turbocharged inline-six with mild-hybrid assist, standard all-wheel drive, dual 12.3-inch displays, built-in navigation, heated leather front seats, and smartphone integration.
