Genesis’s most luxurious model—the G90 sedan—has received a dramatic redesign for the 2023 model year that brings it into the modern era. Exterior styling is inspired by the G80 sedan and GV80 SUV but with a few unique touches that symbolize the G90’s place at the top of the company’s model hierarchy. A twin-turbo 3.5-liter V-6 is under the hood as the standard powertrain and it makes a stout 375 horsepower. Rather than the 5.0-liter V-8 that’s was upgrade engine in the 2022 model, a 409-hp version of the twin-turbo V-6 is offered and it uses an electric supercharger to increase its output. Both powertrains are smooth and quiet, which helps the G90’s cabin remain a relaxing place, designed to pamper occupants with a plethora of unexpected features. For example, an on-board fragrance diffuser can fill the space with a relaxing scent while an air purifier works to prevent odors from outside from filtering in. Standard power-operated doors serve as your own built-in valet and all G90 models come decked out with nappa leather upholstery, genuine wood trim, and massaging front seats.
What’s New for 2023?
The G90 has received a complete overhaul for 2023 that modernizes it and brings the flagship luxury sedan’s styling in line with the rest of the Genesis lineup.
Pricing and Which One to Buy
The G90 continues its value-focused strategy of undercutting the Mercedes-Benz S-class, but its starting price has increased significantly over the 2022 model. The G90 is essentially loaded with all manner of technology and luxury features, so the only choices are exterior and interior colors and to pick from the base turbo V-6 or the more powerful turbocharged-and-supercharged version. Of course, we’d pick the latter. Going with the E-supercharged model also maxes out the G90’s features, with reclining rear seats with heat, ventilation, and massage.
Engine, Transmission, and Performance
The G90 has ditched its 5.0-liter V-8 engine this year in favor of a twin-turbocharged V-6 that’s offered in two potencies; both are paired to an eight-speed automatic and all-wheel drive. The standard engine makes 375 horsepower but the E-supercharged model makes 409 ponies and uses 48-volt hybrid system and an electric supercharger to boost the output from the twin-turbo V-6. An air suspension is optional and Genesis has said the car will feature a “Chauffeur” driving mode which we assume will create an extra-smooth experience for passengers. Our first test drive was with a G90 that featured the more powerful of the two powertrains and the air springs, which delivered a superb ride and effortless acceleration. Handling isn’t sports sedan crisp, but the G90 holds its own in corners. Enthusiast drivers won’t find much in the way of driving thrills but those who buy the G90 for its relaxing demeanor will find themselves satisfied.
Fuel Economy and Real-World MPG
The most efficient G90 will be the one with the 375-hp twin-turbo V-6. That model is rated for 18 mpg city and 26 mpg highway. Going with the more powerful 409-hp powertrain drops those numbers to 17 mpg city and 24 mpg highway. When we get a chance, we’ll put the new G90 to the test on our 75-mph highway fuel economy test route and update this story with results.

Interior, Comfort, and Cargo
Like the exterior, the G90’s cabin gets an overhaul for 2023 too, with a fresh design and posh materials that will help it go head-to-head with rivals such as the Audi A8 and the BMW 7-series. Passenger space is generous in both the front and the back seats and Genesis has incorporated several features that intend to take the luxury experience up a notch. An on-board fragrance diffuser, for example, and an anti-microbial sanitation system that cleans both the air and items that are brought into the car such as smartphones. Of course, features such as massaging front seats and a premium stereo system are also included. All models come with soft, nappa leather upholstery, power-operated rear sunshades, and active noise cancellation to keep the cabin whisper quiet. The rear seats can be made to recline and can also be equipped with massagers.
Infotainment and Connectivity
Genesis’s latest infotainment interface is rendered crisply on a 12.3-inch infotainment display which also features navigation and SiriusXM satelite radio; a separate 12.3-inch display serves as a digital gauge display. Apple CarPlay and Android Auto are also included, but sadly require a cord, an odd omission in the time of wireless connectivity. All models come with a Bang and Olufsen stereo system, but the E-supercharged comes with an upgraded version complete with 23 speakers and a mode that simulates the acoustics of a concert hall. A head-up display and a wireless smartphone charging pad are also included.
Safety and Driver-Assistance Features
Every version comes standard with lots of driver-assistance technology, including automatic high beams and an adaptive cruise control system with a lane-centering feature. For more information about the G90’s crash-test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:
- Standard forward-collision warning and automated emergency braking
- Standard lane-departure warning and lane-keeping assist
- Standard adaptive cruise control with a lane-centering feature
Warranty and Maintenance Coverage
Not only does Genesis provide the longest warranty coverage in its class, it also includes complimentary scheduled maintenance and other perks such as a complimentary service where dealership staff will pick up the G90 and take it in for service on your behalf.
- Limited warranty covers 5 years or 60,000 miles
- Powertrain warranty covers 10 years or 100,000 miles
- Complimentary maintenance is covered for 3 years or 36,000 miles
