2026 Mercedes-Benz C-Class vs. 2026 Lexus IS Comparison

To discerning buyers who prize compactness as highly as comfort in a luxury sedan, the 2026 Lexus IS and 2026 Mercedes-Benz C-Class are worth a look. Two perennial class favorites, they each have their merits. But their personalities are different enough that many buyers, after a pair of test drives, will have a clear favorite.

The current generation of the IS may be the more venerable of the two competitors, as Lexus refreshed it for 2021 after seven years. But Mercedes-Benz redesigned and upgraded the C-Class sedan for the 2022 model year. Both have been updated every year since, keeping them contemporary and loaded with high tech.

Let’s explore the highlights of the Mercedes-Benz C-Class and Lexus IS to see which compact luxury sedan appeals to you. 

2026 Lexus IS

2026 Mercedes-Benz C-Class vs. 2026 Lexus IS Comparison

Lexus drastically simplified decisions for IS shoppers in the 2026 model year. The car was long offered with a choice of three engines, but now comes with just one — a 311-horsepower V6. It comes in rear- or all-wheel drive (RWD or AWD), and every trim level gets appearance upgrades from the Lexus F Sport performance lineup, as well as the option of an F Sport Handling Package. But this may be the last year for the IS. Lexus built an “ultimate edition” in 2025 — usually a sign that a production run is ending — and cut 4- and 8-cylinder engine options from the lineup.

Lexus IS Highlights

Classic styling: This is a matter of taste, but the IS will appeal to buyers who prefer feeling like they are driving a car rather than helming a console aboard the starship Enterprise. The exterior design continues to be sharp and is still the best it’s ever looked.

Resale value: Resale value is a Lexus calling card because Lexus holds its value better than most luxury brands, even the much-coveted Mercedes-Benz. We suppose there’s something to be said for not being on the leading edge of technology — that, and quality craftsmanship and dependability.

Mark Levinson Sound: Audiophiles take note — the optional 17-speaker Mark Levinson sound system available in the IS is one of the best you’ll find in this class.

2026 Mercedes-Benz C-Class

The 2026 Mercedes-Benz C-Class lineup begins with the C 300, powered by a turbocharged 2.0-liter 4-cylinder engine with a 255-hp rating. This mild-hybrid engine couples to a 9-speed automatic transmission that can also transfer power to the rear wheels only or all of them simultaneously. The 48-volt mild-hybrid system can electrically deliver another 20 hp and 148 lb-ft of torque for quick bursts. Mercedes also offers a pair of high-performance AMG models, significantly more powerful and significantly more expensive.

Mercedes-Benz C-Class Highlights

Hi-tech cockpit: The C-Class has arguably the most tech-forward cabins in the compact sedan segment. Its MBUX (Mercedes-Benz User Experience) system can learn routines and automate some of your preferences. Want a car that automatically turns on the heated steering wheel and seats when the temperature is below freezing? You can program that into the C-Class.

Mercedes-AMG models: AMG modes are pricey, but Lexus has nothing to compete with them. C-Class buyers can opt for 416 hp and 670 hp versions that look aggressive with extensive functional vents and have tighter handling.

Biometric fingerprint scanner: Emphasizing the high tech of the C-Class, every trim level provides this cutting-edge access to the personalized-settings profile of each programmed user.

Conclusion

The 2026 Lexus IS carries a lower starting price and holds its value better over time. We think it looks sportier, and its lower starting price means you can add sporty options like the F Sport Handling package without paying AMG prices. It’s likely the right choice for many buyers.

MBUX makes the C-Class feel a little more tech-forward, and some shoppers are drawn to the Mercedes name. Those are valid reasons to prefer the C-Class if the Lexus value argument doesn’t sway you.
