Driving the 2026 Genesis G90 3.5T E-SC Prestige Black AWD, I’m on the lookout for potholes. Not to avoid them, but to hit them and see if they can have any effect on cabin comfort. This thing is just unflappable, and over the course of a week in the South Korean brand’s flagship sedan, I simply can’t find a pothole that makes the car flinch. The culprit here is Genesis’s Preview-Electronic Control Suspension, which uses cameras to monitor the road ahead and adjusts the adaptive dampers before the car hits a rut or bump to best deal with that road imperfection. Even on big 21-inch wheels, the G90 irons out bumps with the best of them. It’s part of the luxurious tuning that puts the G90 in the ballpark of the luxury sedan leader, the Mercedes-Benz S-Class…but for less. Seeking out twisty roads isn’t quite as impressive as dealing with potholes. In addition to the adaptive dampers, Genesis sets the G90 on a four-corner, multi-chamber air suspension and outfits the E-SC models with standard rear-axle steering and staggered 245/40R21 front and 275/35R21 rear tires. At 207.7 inches long on a 125.2-inch wheelbase and weighing in at 5,150 pounds, the G90 is just too big to handle well, and, besides, that isn’t its mission. In the mold of the S-Class, the G90 prioritizes comfort over agility. There’s lean in corners, but it’s not excessive, and it tightens up a bit in the available Sport drive mode. The steering, while light, is fairly quick and stable on center. The rear-axle steering can turn the rear wheels up to four degrees opposite of the fronts at low speeds, reducing the turning radius by three feet and helping to maneuver the car into parking spaces. At higher speeds, the rears can turn with the fronts for better stability during lane changes or high-speed cornering. The E-SC models get larger brakes featuring 14.2-inch rotors all around with four-piston front and single-piston rear calipers. Like the rest of the car, braking is smooth and strong. Genesis lets drivers customize the braking with a Chauffeur mode that has three settings. The goal here is to brake smoothly to avoid disrupting passenger comfort, like a good chauffeur might by feathering the brake pedal. This mode just makes that easier. The smoothness extends to the powertrain. Every G90 gets a twin-turbocharged 3.5-liter V6. Genesis outfits the 3.5T E-SC models with what it calls an e-Supercharger, but it’s really just a 48-volt mild-hybrid starter-generator that can aid acceleration and add some power. Total system output it 429 horsepower and 405 pound-feet of torque compared to 375 hp and 391 lb-ft without the electric motor. Power flows to all four wheels through an eight-speed automatic transmission. The powertrain provides the smooth, easy power buyers expect in a flagship sedan. The engine purrs away in the background as the G90 pulls strongly from a stop to hit 60 mph in 5.1 seconds, according to Car and Driver testing. Shifts from the eight-speed automatic are nigh on imperceptible as well. The mild-hybrid system does little for fuel economy. In fact, it lowers the EPA figures from 18 mg city, 26 highway, 21 combined to 17/24/20 mpg. However, those numbers are easy to achieve in the real world. Over 130 miles of mixed driving with a quite a few highway miles, I averaged 22.2 mpg, according to the trip computer. As pleasant as the G90 is to drive, it’s a better place to spend time. Genesis pulls out all the stops to make occupants not just comfortable but also relaxed. It starts with doors that are damped, soft-closing, and can be closed remotely via buttons on the center console. The driver’s door even closes automatically when the driver gets in and puts their foot on the brake pedal. Generous sound deadening and active noise cancelation make the G90 bank-vault quiet on the road. The Prestige Black treatment is both stark and elegant. The Obsidian Black Monotone interior features soft, diamond-pattern semi-aniline leather upholstery and black Ash open-pore wood trim. Even the door handles, shifter, and infotainment dials, and climate controls are black. How much more black could this be? The answer is none, none more black. But comfort is king. The Prestige Black comes standard with an 18-way power-adjustable driver’s seat and a 16-way front passenger seat, both with power bolsters, heating, ventilation, and a massage function. There’s also a heated power tilt/telescoping steering wheel, three-zone automatic climate control, active noise cancellation, a fragrance dispenser, and what Genesis calls a Mood Curator. The Mood Curator offers four 10-, 15-, or 20-minute programs to help occupants unwind using the ambient lighting, audio system, fragrance, and seat massagers to create an invigorating or relaxing atmosphere. Between the quiet cabin, smooth ride, and high-quality materials, the G90’s interior is cosseting enough. These programs just provide excellent ways to take a time out. Of course, the G90 Prestige Black comes with a full tech suite as well. It includes a 12.3-inch digital instrument cluster, a 12.3-inch touchscreen, navigation, wireless Apple CarPlay and Android Auto, satellite radio, a wireless phone charger, and a rockin’ 23-speaker Bang & Olufsen audio system. The infotainment is quick to react and packed with features, but it’s easy to confuse the rotary shifter with the rotary infotainment controller. While I don’t get to sit back there except in the driveway, the rear seat is also very welcoming. It features power-adjustable reclining and massaging seats with heating and ventilation, as well a wireless phone charger, power rear and rear side sunshades, and a right-side footrest. While rear legroom is plentiful, the front passenger seat doesn’t move forward far enough for this seat to let passengers stretch out fully. The 2026 Genesis G90 3.5T E-SC Prestige Black AWD is offered in Vik Black or Uyuni White. No matter the color, the exterior also gets the black 21-inch wheels and a dark treatment for the headlamp bezels, exterior trim, and badges. It costs $105,750, including a $1,495 destination fee. That’s $2,250 more than the top 3.5T E-SC MHEV AWD model, but about $15,000 less than the base Mercedes-Benz S-Class. It may crest the six-figure threshold and not offer quite the cachet of the Mercedes-Benz S-Class, but the 2026 Genesis G90 3.5T E-SC Prestige Black AWD hits all the S-Class notes for less money while offering a sinister style of its own. If you can get behind the wheel of one, let me know if you find a pothole that disrupts its silky-smooth ride. View All Genesis for Sale Images: Genesis
