2026 GENESIS G90 VS. 2026 MERCEDES-BENZ S-CLASS

Head-to-head review

Nothing feels more personal than a luxury sedan like those artfully crafted by high-end brands such as Genesis and Mercedes-Benz. But finding your personal touch isn't always as easy as it seems. We're here to help you find your perfect vessel in this comprehensive comparison between two of the newest models by these distinguished automakers. Learn more about the new 2026 Genesis G90 and the 2026 Mercedes-Benz S-Class before visiting Genesis of Columbus for new luxury sedans near you.

Superior Performance

To Genesis, drive quality is the foundation of a memorable luxury car that leaves a lasting impression. A 3.5L engine with AWD comes standard in the new 2026 Genesis G90 with 375 horsepower and 391 lb-ft of torque, but the real treasure lies in its available e-Supercharger platform that's exclusive to the brand. The 3.5L Twin-Turbo V6 E-SC boosts your power to 409 HP, but more importantly, optimizes your drive for low-end torque so you can ride on smooth ground when casually cruising Columbus in your G90.

Mercedes-Benz made an attempt at a mild hybrid powertrain with the 2026 S-Class model, but it doesn't quite live up to the dynamic drive quality of the Genesis G90. Yes, the S-Class makes 442 horsepower on a 3.0L turbo engine, but is that what you really want in a luxury drive? Power without discipline can feel rather gaudy, and that's why we'll always recommend the poise and grace of Genesis' e-Supercharger over any competing platform.

Top Safety

An easy drive is the cornerstone of every successful luxury sedan. That's true in every aspect, especially safety. Remote Smart Parking Assist 2 helps keep your 2026 Genesis G90 in pristine condition while sparing you from an avoidable collision. This updated system makes it easy to parallel, diagonal, and perpendicular park to accommodate any destination in Columbus (or any other bustling city). Other hand-selected systems to ensure you stay safe in the new Genesis G90 include Smart Cruise Control, Highway Driving Assist 2, and a Blind Spot View Monitor.

Many of the better safety features in the new 2026 S-Class are too specific to be considered practical. Crosswind Assist is only useful in situational moments, offering stability whenever you're hit with a heavy gust of wind. Even while active, many drivers might not appreciate the automatic braking that occurs in response to high winds. Car-to-X Communication can only be used with other Mercedes-Benz vehicles with Car-to-X Communication within a certain radius. When do you think that might happen? If your idea of luxury is owning features that are doomed to remain on standby, unused for long periods at a time, then by all means. We much prefer luxuries that can be used every day of the week.

Opulent Interior

Genesis loves their sedan line, and it shows in the 2026 Genesis G90's outstanding interior design and choice of top-tier amenities. Nappa leather seats welcome you with the promise of soft-touch textures and plush comfort. Front seats offer 4 custom massage modes, which are available for rear-seat enjoyment. The exclusive Mood Curator by Genesis creates a spa-themed atmosphere with tailored lighting, massage functions, and fragrances. Let your favorite music hug you in a loving embrace with the available B&O Premier 3D sound system with 26 speakers and 2 separate amplifiers. Rear-seat passengers can command their own experience with an 8-inch rear armrest touch display that controls seat position, massage mode, ambient lighting, temperatures, and sunshades. Adopt a showstopping style in the Genesis G90 Prestige Black trim in Columbus, dressed in black semi-aniline quilted seating surfaces and Black Ashwood accent pieces.

Mercedes-Benz is consistent in offering features that don't feel the most useful. The S-Class promotes "rapid" heating seats, but is the difference in heating time vast enough to give it a distinct label? You might not notice unless you were told. S-Class owners can pay extra for heated armrests, but can you imagine keeping your arm still long enough to bask in the warmth? Mercedes-Benz markets the impractical, whereas Genesis caters to your ambitious idea of luxury.

The bottom line

What feature do you love most in a high-end car? Or, what does your ideal day look like with your sophisticated ride? The 2026 Genesis G90 is designed for those in Columbus who desire a sedan that improves quality of life for everyday luxury without the chaos of unneeded gimmicks.
