2023 Genesis G90 Review

Introduction - Find the best Genesis deals!

Sinatra would get the Genesis G90. Like Ol' Blue Eyes himself, the range-topping flagship's got a big persona, goes its own way, and has a smooth delivery. As with the big and unapologetically brash Cadillacs and Chryslers of the late 1950s and early 1960s, the G90's design is all Genesis, owing nothing to the look of other luxury sedans from established European luxury blue-blood marques.

The G90 is the largest of three sedan models in the Genesis product lineup, standing 207.7 inches nose to tail, which is just 3 inches shy of the length of a full-size Chevrolet Tahoe. Yet the G90 seen here is the smaller of two available in international markets, with a longer, stretched-wheelbase version offered in Asia and other regions with extensive chauffeur-driven demand.

While the G90 doesn't sell in big numbers in North America, it shows that Hyundai Motor Company's luxury brand is a serious contender in the large premium sedan space. Although some $13,000 more dear than the 2022 G90, the new 2023 model still undercuts the volume-leading Mercedes-Benz S-Class on price, presenting a "smart with money" value proposition despite a convincingly rich and newly expanded array of advanced tech and standard comfort and convenience features.

In the United States, buyers can choose from two 2023 Genesis G90 configurations: 3.5T AWD and 3.5T E-Supercharger AWD.

Redesigned for the 2023 model year, the all-new G90 gets fresh sheet metal and luscious cabin fitments. Genesis discontinued the previous naturally aspirated 5.0-liter V8 and 3.3-liter V6 twin-turbocharged powerplants. All-wheel drive (AWD) is now standard.

Highlights of the 2023 G90 3.5T AWD include:

  • New 375-horsepower 3.5-liter twin-turbo V6
  • 8-speed automatic transmission with console-mounted rotary shifter
  • Adaptive suspension damping
  • 20-inch alloy wheels
  • Power door closers
  • 15-speaker Bang & Olufsen premium audio
  • Fingerprint authentication
  • Nappa leather seating
  • Power front seats with massage function
  • Mood curator
  • Power rear sunshades
  • Adjustable interior ambient lighting
  • Heated and ventilated front seats
  • Heated rear seats
  • Heated power tilt/telescopic steering wheel
  • 3-zone automatic climate control
  • Front console wireless charger
  • Antibacterial chamber for small electronics
  • Genesis Digital Key 2
  • Head-up display

Upgrading to the G90 3.5T E-Supercharger AWD brings:

  • New 409-hp 3.5-liter twin-turbo V6 with "E-Supercharger" mild-hybrid electrification
  • Air suspension
  • Rear-wheel steering
  • 21-inch alloy wheels
  • Easy-close power doors
  • Power-adjustable, reclining, massaging, and ventilated rear seats
  • Rear console wireless charger
  • 26-speaker Bang & Olufsen 3D premium audio with customizable Virtual Venues sound stage replication

Getting In and Getting Comfortable - Find the best Genesis deals!

As the Genesis brand's range-topping sedan offering, the G90 is all about comfort and craftsmanship. It's technically a 5-seater, but four passengers will travel in the lap of luxury with the rear seat center armrest lowered. Genesis equipped the top-of-the-line 3.5T E-Supercharger test car with standard power-operated outboard rear seats that are heated, ventilated, and bestowed with a massage function. In its lowered position, the rear center armrest functions as a control panel for rear-seat audio, climate control, and the aforementioned seat heating, cooling, and lower body massage. The rear seatbacks recline sufficiently to facilitate power naps or evening stargazing through the standard panoramic moonroof. Customizable ambient accent lighting along the sides of the console, door uppers, mid-dash, and key controls stages the lux sedan's upscale design and creates a soothing atmosphere.

Up front, the driver and front passenger luxuriate in creamy-soft, generously sized Nappa leather-covered seats that support the occupant's torso and thighs for long or short slogs. The front seats also have heating, ventilation, and massage functions. In Mood Creator—a new G90 feature—you can program the climate control system to dispense one of several refreshing fragrances or run the massage feature for a while if the vehicle detects that the driver has been on a long, straight road for an extended time. That happened to me during a long interstate slog and was a welcome bit of invigoration.

Thanks to the generously sized doors, ingress and egress are a breeze with the G90. The G90 doesn't have the face-recognition pad as found on the Genesis GV60 electric crossover SUV, but it does support Genesis Digital Key 2, which allows registered owners to unlock doors using their cellphone or Apple Watch as a key. The doors unlatch electrically, and once pulled open manually, a seated occupant can close them after pushing a console-mounted button. You can also close the doors manually, and in the e-supercharged G90, they feature a soft-close function that takes some getting used to. I found the electric-closing and soft-close doors to be an unnecessary embellishment, but it is a feature often found in bespoke ultra-luxury Bentley and Rolls-Royce cars. The point is you can use the electric assist if you want to, but you can manually do it just as easily.

Interior materials are top-notch in the G90. Fit, finish, and craftsmanship are superb. Interior storage is quite good as well, with a large, covered bin under bomb-bay doors that form the center armrest; a Tambor-door covered tray with cupholders, a wireless charger, and USB ports at the front of the console; bins for maps and beverages in the doors; and a generously sized glovebox.

2023 Genesis G90 Infotainment System Review - Find the best Genesis deals!

The standard G90 infotainment system includes:

  • Horizontal-format 12.3-inch high-definition touchscreen
  • Embedded navigation
  • Console-mounted remote controller
  • Wired (not wireless) Apple CarPlay and Android Auto smartphone mirroring
  • Advanced voice control
  • 15-speaker, 1,400-watt Bang & Olufsen AM/FM/SiriusXM/HD Radio premium audio system
  • Front wireless device charger
  • Connected services
  • Five Type-C USB ports (3 in front, 2 in rear)

In addition to the pleasantly responsive voice control and amply sized tiles on the touchscreen, interacting with the infotainment system is easy and natural. There are redundant hard shortcut buttons just above the climate control panel and Mercedes-Benz-style scroll wheels for volume and tuning on the center console, plus a nicely knurled tap-up/tap-down hard button with actual physical movement you can feel for volume control on the steering wheel. The remote control wheel for infotainment functions on the console has knurling and just-right weighting to its action for a precise feel.

Genesis equipped the G90 3.5T E-Supercharger AWD test car with the upgraded 26-speaker 3D Bang & Olufsen audio system. You know you're in for a treat when, upon powering up the audio system, a pair of tweeters pop up at both corners of the top of the instrument panel. This system includes a G90-exclusive feature called Virtual Venues that, in addition to its 3D, surround-sound architecture, has programming designed to replicate the sound stage of featured music meccas such as Boston Symphony Hall and others. In-car microphones monitor the produced sound, and the system reduces ambient noise in the cabin for a sharper, more vivid audio experience.

The horizontal-format infotainment screen can simultaneously display as many as three different functions, such as audio, navigation, and phone.

The advanced voice control responds quickly and accurately to such voice requests as point-of-interest searches, changing audio sources, and climate control adjustments.

Despite the overall excellence of the G90 infotainment package, there are a few misses. Apple CarPlay and Android Auto smartphone mirroring requires a USB connection, so there is some wire clutter that you don't see in most contemporary luxury sedans. Also, the G90 does not offer an in-car Wi-Fi hotspot.

What It's Like to Drive the 2023 Genesis G90 - Find the best Genesis deals!

In a nutshell, the 2023 Genesis G90 is amply powerful, confidently waftable, relaxed over long distances, and among the most hushed sedans on the road.

The G90 gets two new power plants for 2023 that replace the prior year's 3.3-liter twin-turbo V6 and 5.0-liter naturally aspirated V8. The "base" 3.5T model gets a twin-turbo 3.5-liter V6 with 375 hp and 391 pound-feet of torque, while the uplevel 3.5T E-Supercharger trim utilizes a mild-hybrid-boosted version of the twin-turbo V6 pumping 409 hp and 405 pound-feet of torque. The e-supercharger isn't a supercharger that pressurizes the intake charge in the traditional sense but rather a belt-driven 48-volt electric motor that helps fill in the gaps in the power curve, such as when accelerating from rest and smoothing the in-gear restart after an engine stop at a traffic light. Both engines work with a slick-shifting 8-speed automatic transmission and confidence-inspiring AWD. According to Genesis, each can accelerate the G90 from zero-to-60 mph in about 5 seconds. The e-supercharger one is just a bit smoother in the process, and it's the engine that powered the test car for this review.

Quicker gas-powered examples from competitors such as AudiBMW, and Mercedes-Benz are available. Indeed, any large luxury electric such as the Mercedes EQS or Lucid Air would smoke the G90 in a zero-to-60-mph runoff. But the Genesis G90, confident in its own skin, is powerful enough to deliver the luxury goods. In e-supercharger trim, the standard air springs and 4-wheel multi-link suspension provide a well-controlled, creamy ride quality fitting of the G90's flagship mission. It's seemingly immune from rude, harsh impacts over ruts or potholes despite the thin sidewalls of the 21-inch tires upon which it rides.

With a quick 11.95:1 steering ratio and just 2.34 turns lock to lock, the G90's rack-mounted electric power steering is pleasantly precise yet relaxed on-center with a light effort that suits the range-topper's luxury mission. On the e-supercharged model, rear steering enhances low-speed maneuverability and shrinks the G90's turning diameter by 3 feet, from 40.1 to a midsize sedan-like 37.1 feet despite the car's stretchy 125.2-inch wheelbase.

Tipping the scales around 5,000 pounds, the G90 is no lightweight. Still, the large-diameter 4-wheel disc brakes and well-tuned electronic booster deliver pinpoint top-of-pedal response and confidence-inspiring stopping power.

An active noise-control system working through the car's speakers, extra-thick acoustic glass, and extensive soundproofing help knock down engine, road, and air rush sounds inside the cabin to a hushed level worthy of a premium luxury flagship.

In addition to safety features including driver and front-passenger airbags, a driver knee airbag, front-seat-mounted side airbags, a center side airbag, rear-seat side airbags, and roof-mounted side-curtain airbags, the Genesis G90 flagship comes standard with a full roster of safety and advanced driver assistance systems (ADAS). These include:

  • Forward-collision warning
  • Lane-keeping assistance
  • Lane-centering assistance
  • Adaptive cruise control (ACC) with stop-and-go capability
  • Highway Driving Assist II (a hands-on system that combines adaptive cruise control and lane-centering on limited-access highways)
  • Intelligent speed-limit assist (uses camera and GPS to adjust adaptive cruise control set speed to posted limits)
  • Blind-spot warning with collision avoidance
  • Rear cross-traffic warning with collision avoidance
  • Blind-spot view monitor (displays a view of the vehicle's rear quarter blind spot when the driver actuates the turn signal)
  • Automatic high-beam headlight assist
  • Driver monitoring system
  • Head-up display
  • Surround-view camera and reversing camera with trajectory lines
  • Park distance warning sensing for the front, rear, and side
  • Parking collision avoidance assist
  • Safe Exit Assist (warns passengers if a vehicle or bicyclist is approaching from the rear)
  • Advanced rear-seat reminder system (listens for passengers or pets left behind after the driver turns the vehicle off if someone opened a rear door during the last key cycle)
  • Remote smart parking assist

You can easily set up the G90's ADAS technology using the three-panel infotainment screen under the vehicle settings tab. Not only is the menu simple and straightforward to navigate, but the right screen panel also shows a vehicle illustration of how that particular ADAS feature works.

One interesting feature of the ACC system is the ability of the driver to make an automatic lane change after signaling if the blind-spot warning system determines that the lane is clear. As configured, this feature requires the driver to maintain a light grip on the steering wheel even though the vehicle rotates the rim just enough to transition from one lane center to the next smoothly. But apply too much grip or remove your hands from the wheel, and the system will cancel the lane-change maneuver. Some practice on the driver's part is prudent.

Genesis has now integrated some of its ADAS technology, such as the blind-spot warning, into the head-up display. As a result, crucial decision-making information displays directly in the driver's forward field of view, saving crucial time when a quick response can make a big difference.

2023 Genesis G90 FAQ - Find the best Genesis deals!

2023 Genesis G90 Cargo Area

How much cargo space does the 2023 Genesis G90 have?

The 2023 Genesis G90 offers a class-average 12 cubic feet of trunk space in "base" non-supercharged trim and just 10.6 cubic feet in the range-topping e-supercharged model. The e-supercharged test car efficiently handled four airport roller bags and can accommodate another small computer bag or two. There is netting to keep small items from rolling around and some hidden storage for a small item or two under the trunk floor. Genesis concealed the trunk hinges inside sleeves that protect things from getting crushed or dented. Opening is via a hands-free foot wave under the rear bumper or remote button push.

Does the 2023 Genesis G90 get good gas mileage?

The twin-turbocharged and e-supercharged 3.5-liter V6 version of the 2023 Genesis G90 gets an EPA-estimated 20 mpg in combined city/highway driving. That's one mpg less than the standard 3.5-liter twin-turbo without the e-supercharger.

Driven mostly gently in keeping with its smooth, luxurious persona over 214 miles of mixed residential roads and interstate highways, the e-supercharged 2023 G90 averaged an impressive 26 miles per gallon. Based on that result, the G90 test car is capable of a maximum driving range of about 500 miles.

Is the 2023 Genesis G90 safe?

Neither the National Highway Traffic Safety Administration (NHTSA) nor the Insurance Institute for Highway Safety (IIHS) has published safety ratings for the 2023 Genesis G90. However, the IIHS did rate the 2022 G90, which from a structural standpoint, is virtually identical to the 2023 model. The IIHS gave the 2022 G90 Good ratings for small- and moderate-overlap front impacts, side impacts, roof strength, head restraints, seats, and headlights. The G90 received a Superior rating for vehicle-to-vehicle front crash protection and an Advanced rating for daytime vehicle-to-pedestrian crash protection. The IIHS also named the 2022 G90 a Top Safety Pick+.

How much is the 2023 Genesis G90?

Genesis offers two versions of the G90 in the U.S.: the G90 3.5T AWD at $88,400 and the G90 3.5T AWD E-Supercharger at $98,700. The destination charge adds another $1,095.

What are the 2023 Genesis G90 competitors?

In the J.D. Power 2022 Initial Quality Study (IQS), the BMW 7 Series ranks highest in the Large Premium Car segment.

In the 2022 APEAL Study, the Mercedes-Benz EQS ranks highest in the Large Premium Car segment. The Mercedes-Benz S-Class and the BMW 7 Series are the next highest-ranked models.

Other premium 4-door sedan competitors to the 2023 G90 include the Audi A8Lexus LSPorsche Panamera, and Volvo S90.

The big and brash Genesis G90 is a flag in the sand, a proof point that the flagship sedan of Hyundai Motor Company's luxury division can go wingtip to wingtip with Europe's best executive cruisers without breaking the budget. And it does this while delivering an extensive array of safety and ADAS as standard equipment. As the Hyundai Group continues to ramp up its electrification program, the only question is, will there be a battery-electric G90 in a few years?
