The 2026 G90 continues a quiet conversation the flagship started a few years ago. It is a sedan that prefers to be experienced before it is described, and the specification sheet, read carefully, makes the case for why. What follows is a measured walk through what the 2026 model offers, and why those numbers matter less than the way they arrange themselves around the driver.
The Powertrain, in Plain Terms
The 2026 G90 is offered with a twin-turbocharged 3.5-liter V6, and in the higher trim, that engine is paired with an electric supercharger and a 48-volt mild-hybrid system. Power is sent through an eight-speed automatic to all four wheels. The headline figure most readers will look for is horsepower, and the engineering interest sits in how that power is delivered: progressively, without theater, with the electric supercharger smoothing the moment between intent and motion.
This is the point at which a flagship either reveals itself or doesn't. The G90 is tuned for the kind of acceleration you feel in your shoulders before you feel in the speedometer. Designed, then refined.
Chassis, Ride, and the Work the Car Does Quietly
Adaptive air suspension with Preview Electronic Control reads the road ahead through the forward camera and adjusts damping before the wheel arrives at an imperfection. Rear-wheel steering tightens the car's behavior at low speeds and settles it at highway pace. Active road-noise cancellation works in concert with laminated acoustic glass to bring the cabin to a register most sedans cannot reach.
None of this is novel on a spec sheet. What is uncommon is the calibration. The G90 does not advertise its competence; it simply removes friction from the drive. On the stretch of I-35 between Norman and Oklahoma City, the difference shows up as fatigue you don't feel at the end of the trip.
The Interior: White Space, Made Tactile
The cabin is where the 2026 G90 earns most of its second looks. Nappa leather with diamond quilting on the seats and door cards. Real wood — open-pore, not lacquered to a mirror. Knurled metal on the rotary controls. A 27-inch OLED display arcs across the dash without dominating it, because the architecture around it has been composed to give the screen its proper weight rather than its maximum presence.
The rear cabin deserves its own paragraph. The Executive Package configures the right-rear seat as a reclining lounge with an ottoman, a folding tray, and a dedicated touchscreen. Mood curation adjusts lighting, fragrance, sound, and seat massage together. It is a thoughtful piece of design that becomes useful on a long evening — the kind of detail that rewards a second look.
Materials Worth Naming
- Diamond-quilted Nappa leather, front and rear
- Open-pore wood inlays across the dash and console
- Knurled aluminum on rotary and shift controls
- Suede headliner
- Bang & Olufsen audio with 23 speakers in the available configuration
Technology That Stays in the Background
The 27-inch OLED panel consolidates the instrument cluster and infotainment into a single, continuous surface. Highway Driving Assist 2 manages lane centering and adaptive cruise with a calm hand. Remote Smart Parking Assist will move the car in and out of tight spaces from outside the cabin — useful on a downtown OKC garage night when the space next to you is unkind.
Connectivity includes wireless Apple CarPlay and Android Auto, multiple USB-C ports front and rear, and over-the-air updates for the infotainment and select vehicle systems. The fingerprint authentication system, introduced on earlier model years, returns and continues to feel like the right kind of small luxury: present when you want it, invisible when you don't.
Where the G90 Sits in the Lineup
The G90 is the flagship sedan, and the rest of the range is composed around it rather than beneath it. The G80 carries the same design language in a slightly more compact sedan format. The GV80 translates the philosophy into a three-row SUV. The 2026 G70 remains the sport sedan in the family — smaller, more direct, the entry point for drivers who want the design language in a tighter package.
What the G90 offers that the others cannot is the rear seat. If your week regularly involves driving a client, a senior partner, or a guest from the airport to a dinner reservation, the G90 is the car in the lineup composed around that specific evening. For shoppers cross-shopping the segment, browsing the current inventory is the practical next step; the configurations on the ground will tell you more than any brochure.
Ownership, as Part of the Design
Genesis treats service as part of the product. Service Valet pickup and delivery is included during the complimentary scheduled maintenance window, which means the car arrives back at your office or home without you having reorganized your day around it. Connected Services, complimentary for a set period from the in-service date, handles remote start, vehicle status, and the navigation updates that keep the head unit current.
For shoppers who would like to discuss specific build configurations, our finance team can talk through lease and purchase structures once a trim has been selected. The conversation works best after a drive.
A Note on Reading Spec Sheets
Numbers are useful, and they are not the point. The 2026 G90's specifications describe a car that has been engineered to disappear around the driver — to make the route quieter, the cabin calmer, the arrival less rumpled. The work the car does is most visible in what it doesn't ask of you. An evening that begins before you arrive.
