After my week with this 2026 Genesis G90 ended, I realized you start to miss a car that closes its own doors. You step out, time it right, and the door swings shut behind you with quiet, mechanical certainty. By day three, reaching back to pull a car door closed yourself starts to feel like a personal failing. I should have worked harder, saved more money. That is the essence of the G90, not the personal failing bit. It identifies things you didn’t know you needed, then does them so well you immediately start resenting every car that doesn’t. I had lots of thoughts about the latest G90 Prestige Black, continue at your own peril.
2026 Genesis G90 3.5T: Overview
The G90 is Genesis’s flagship full-size luxury sedan, competing directly with the Mercedes-Benz S-Class, BMW 7 Series, and Lexus LS. For 2026, it comes in three configurations. The base G90 3.5T AWD starts at $94,195 and pairs a twin-turbocharged 3.5-liter V6 making 375 horsepower and 391 lb-ft of torque with a conventional powertrain. The mid-tier G90 3.5T E-SC MHEV AWD steps up to $104,495 and adds an electric supercharger and a 48-volt mild-hybrid system, bumping output to 409 horsepower and 405 lb-ft of torque, plus larger wheels, a Bang & Olufsen 3D audio system, and a rear wireless phone charger.
The top-of-the-range G90 3.5T E-SC Prestige Black MHEV AWD, which arrived in my driveway, starts at $105,750 and adds semi-aniline leather seating, floating center wheel caps, and dark exterior and interior trim accents that set it apart visually from the E-SC MHEV. The test car’s only added option was the UNI WHITE paint at $650, bringing the as-tested total to $107,895.
All three share the same eight-speed automatic transmission and AWD system. The MHEV trims are rated at 17 city, 24 highway, and 20 combined. The 0-60 time is around 5.2 seconds.

2026 Genesis G90 3.5T Prestige Black AWD: Inside & Out
The UNI White exterior is genuinely vibrant, a brighter, more vivid white than the pearl or silver-whites most luxury sedans default to. It commands attention. It also accumulated road grime at an impressive pace, which seems to be the tax you pay for that much visual presence.
The exterior design is stately and substantial, though it is not an especially interesting car to look at. The G90 makes its statement through proportion and presence rather than surfacing details. The wheels on the Prestige Black look…fine, a bit of a love-it-or-hate-it situation.
Inside, describing the G90 as fully loaded is a bit of an understatement. The seats have their own dedicated massage button on the side panel, right next to the memory controls. The massage function is one of the better implementations you will find in any car at any price: multiple programs, well-calibrated intensity, and comfortable enough on the highest setting to use for a full commute without it becoming aggressive.
Storage upfront is the one area where the G90 asks for a bit of compromise. The cupholders sit farther back than ideal, and the center console lid, when closed, presents a slick plastic surface that nothing can sit on without sliding around. You can open it and use the interior storage, but then you lose it as an armrest. The wireless charger works reliably once you find the exact right placement for your phone, which takes a couple of tries to learn.
Pair that with heated seats that don’t immediately go scorching hot, and a chilly morning commute becomes genuinely pleasant. The heated seats on the highest setting felt appropriate rather than punishing, which is an unusual achievement. One thoughtful detail: when you hover a finger over a seat control button, the function it controls pops up on the adjacent screen before you even press it. It is a small thing that makes the interface feel considered rather than just comprehensive.
The one tech hiccup: the screen went pixelated once during the test week. Exiting CarPlay and returning fixed it immediately. Probably a software quirk rather than a hardware issue, but worth noting. However, the screens are large and well integrated. They don’t have that tacked-on tablet look that plagues many modern interiors. The Prestige Black’s dark interior trim gives the cabin a composed, almost monochromatic quality that suits the car’s character.
The trunk is massive, as you would expect. I had to attach the cargo net to keep groceries from rolling around. It swallowed the hockey bag with ease, and we used the pass-through for the sticks.
2026 Genesis G90 3.5T Prestige Black AWD: On the Road
Comfort mode is where this car lives, and it is notably quieter there than in the sportier setting. The cabin isolation is exceptional. Road and wind noise recede to the point where you start noticing the audio system more than what is happening outside. The Bang & Olufsen setup on the Prestige Black is very good.
On the topic of sound, the proximity alerts for parking are routed through the driver’s headrest speakers rather than the main audio system. You hear the beeps right next to your ear, distinctly and without competing with the music. The Waze navigation voice comes through the same way. The turn signal click is in there too. It is a genuinely clever spatial audio implementation that keeps audio cues where they are useful without interrupting what you are listening to.
The car makes a credible attempt at a three-point turn in a tight residential street without needing a second click to select reverse. The turning radius is notably tighter than the base 3.5T, which is a meaningful real-world advantage for a car this size.
A note from the back seat: the heated seat controls are in the touchscreen’s climate panel, not the seat controls, where passengers tend to look first. Not a major issue, but more than one rear passenger went looking in the wrong place. Luckily there are also some redundant physical buttons up on the door.
Speaking of doors, let’s talk about the automatic doors. As the driver, or chauffeur, you can close any door from buttons inside the car. As you or your guests enter, you sort of have to time it right as you step out and let it close on its own. By the end of the week, you will be thinking about how inconvenient it is to close your own doors.
Summary
The 2026 Genesis G90 3.5T E-SC Prestige Black MHEV AWD is a genuinely impressive flagship sedan. The massaging seats, spatial audio for proximity alerts, automatic doors, and heated seats that don’t punish you are features that sound like line items on a spec sheet but feel meaningful in daily use. At $107,895 as-tested, it competes with the BMW 7 Series and Mercedes S-Class, and I have to say it holds up. The interior quality is excellent, the powertrain is smooth and powerful, and the cabin isolation is among the best in class.
The cupholder and console storage situation is a bit of an ergonomic gap at this price. The screen pixelation needs a software fix. These are real notes, not nitpicks, on an otherwise very accomplished machine. Genesis continues to make a strong case that you don’t have to pay a German badge premium to get into the top tier of full-size luxury sedans. The G90 makes that argument more convincingly than ever.
