Thinking of leasing a Genesis G90?

The U.S. News Best Price Program saves users an average of $3,206 off the MSRP, and a lower price equals lower monthly lease payments. That means you could see a savings of $90 a month on a 36-month lease.

Is the Genesis G90 a Good Car?

Yes, the Genesis G90 is an excellent car. As the brand's flagship sedan, it offers top-notch craftsmanship and a long list of comfort and convenience amenities that enhance an already sublime cabin experience. The G90 goes down the road with a commanding presence, powered by either a twin-turbocharged V6 engine or a V8. It also delivers the pampering ride quality you'd expect from a luxury large car.

You really have to nitpick to identify weaknesses. If anything, it's that the G90 is less athletic than some rivals are, though it’s not really trying to be sporty. It also returns poor fuel economy, but that isn't always a huge concern when driving a large and expensive car.

Should I Buy the Genesis G90?

The 2021 G90 has a higher base price than all other class rivals, but a vast list of standard features actually makes it somewhat of a value. You'll be hard-pressed to find a more well-rounded luxury sedan at this price point.

2020 vs. 2021 Genesis G90: What's the Difference?

There are only minor changes to the G90 for 2021. Genesis adds a Rear Comfort setting to the adjustable drive modes and makes tech improvements such as natural voice recognition, over-the-air updates for navigation, and enhancements to remote start options.

Compare the 2020 and 2021 G90 »

Here are the key changes for the Genesis G90 over its existence:

  • 2017: all-new model
  • 2018: gained standard LED headlights; rear-seat entertainment system became available
  • 2019: no major changes
  • 2020: refreshed exterior design; Android Auto, Apple CarPlay, lane tracing assist, highway driving assist, reverse automatic emergency braking, and safe exit assist added to standard features list
  • 2021: gains Rear Comfort drive mode setting; improved voice recognition and navigation operation

How Much Does the Genesis G90 Cost?

The base 2021 Genesis G90 starts at $72,950, making it the most expensive in the luxury large car class. However, there isn't as big of a range of prices with the G90 as you'll find with other class rivals. Genesis offers only one other trim level – with a more powerful engine – at $76,700. The only notable option for either trim is all-wheel drive, which costs $2,500.

Genesis G90 Versus the Competition

Genesis G90 vs. Kia K900

The Kia K900 is about $13,000 cheaper than the G90, and that price difference is reflective in a somewhat less impressive interior. While there's nary a subpar surface in the Genesis, the Kia has a few noticeable harder plastics. Both of these luxury large cars are products of the same Hyundai parent company, so you'll notice many similarities. That includes the same twin-turbo base engine, nearly identical standard and optional features, great seating accommodations, and equivalent warranty coverage.

The G90 rates higher for predicted reliability and offers an optional V8 engine. If you have the extra room in your budget and you prioritize its added luxury, the G90 is the better choice. However, the K900 is still a solid pick in the class and the better value proposition.

Compare the G90 and K900 »

Genesis G90 vs. Lexus LS

The Lexus LS competes in the super luxury car class. It's a good vehicle on its own, with strong acceleration, a great predicted reliability rating, and a handsome cabin. However, it fails to match high-end cars that have better infotainment controls or roomier rear seats. The LS' most notable advantage in the segment is price: It offers savings of more than $10,000 over its closest class rival, but costs can balloon as you add options or if you spring for the more fuel-efficient LS Hybrid.

The base G90 is a few thousand dollars cheaper than the LS, and it has a longer list of standard features, but the Lexus offers exclusive amenities such as massaging seats and a sport suspension.

G90 Interior: Among the Best in Class

G90 Cargo Space

The Genesis G90 has a wide, large trunk that makes carrying luggage or groceries a breeze. With 15.7 cubic feet, there's more space than what several class rivals offer.

How Many People Does the G90 Seat?

This luxury sedan seats five people in near world-class style. The driver's seat comes standard with 22-way power adjustments, as well as an automatic position calibrator. Enter your physical measurements like height and weight, and the seat will configure to an optimal setup. The front passenger won't enjoy this technology but can use 16-way power adjustments to find a relaxing position.

The second row rivals the first for comfort and opulence. There's ample head- and legroom for taller people, along with a number of optional upgrades. That list includes a dozen or more power adjustments, reclining ability, and memory functions.

G90 and Child Car Seats

There are two complete sets of LATCH connectors for the G90’s rear outboard seats and a tether anchor for the rear middle seat. The lower anchors are set deeply in the seats, but it's easy to maneuver your hands around the anchors, and it requires little effort to attach the straps.

G90 Interior Quality

The G90 hits the mark for what a flagship luxury vehicle should be. All materials are of the highest quality, and build construction is excellent. The G90 impresses with standard Nappa leather on the seats and center console, along with plush coverings on nearly all other surfaces. Trim accents include open-pore wood and stainless steel.

G90 Infotainment, Bluetooth, and Navigation

In-car technology is generally a high point. The touch-screen system is responsive and easy to understand, echoing the user-friendliness of other infotainment systems from the Hyundai and Kia parent company. However, despite the large display size, some critics note that the graphics are a little plain and reminiscent of a lower-priced car.

In addition to touch capability, you can control the G90's infotainment with a rotary knob on the center console. It has an ergonomic feel to it and offers some relief from having to reach toward the display while driving.

  • Standard infotainment features: a 12.3-inch touch screen, Android Auto, Apple CarPlay, a 17-speaker Lexicon surround-sound stereo, wireless device charging, navigation, a satellite radio, HD Radio, Bluetooth, and multiple USB ports
  • Available infotainment features: a rear-seat entertainment system with dual 10.3-inch touch screens
  • Additional standard features: tri-zone automatic climate control, a sunroof, interior ambient lighting, power rear-window sunshades, proximity keyless entry, remote start, an auto-dimming rearview mirror, a universal garage door opener, and a 7-inch digital instrument cluster display

G90 Performance: Throwback Style

G90 Engine

The Genesis G90 features a standard 3.3-liter twin-turbocharged V6 engine that churns out 365 horsepower and 376 pound-feet of torque. Ample torque and minimal turbo lag help get this car moving quickly and with authority.

Your other choice for under the hood is a 5.0-liter V8 with 420 horsepower and 383 pound-feet of torque. Its power delivery is a little more linear and spread out, in contrast to the immediate thrust from the base engine. Overall, there's not that big of a performance difference between the two powertrains, and thus, little reason to pick one over the other.

The naturally aspirated V8 is the only such offering in the class, and with a raucous exhaust note, it lends a certain old-school character to this big luxury sedan.

G90 Gas Mileage

A casualty of those potent powertrains is poor fuel economy, as the 2021 G90 gets some of the worst estimates in the luxury large car class. Models with the twin-turbo V6 return 17 mpg in the city and 24 mpg on the highway, while V8-equipped G90s get 16 mpg in the city and 23 or 24 mpg on the highway.

G90 Ride and Handling

When it comes to handling, the name of the game is subtlety. The G90 is most at home while cruising, with an electronic adaptive damping suspension that effortlessly does away with bumps in the road.

The steering is light, so it's easy to pilot this big car through turns. However, there's not a lot of feedback from the road, and you'll likely notice a little body roll. This is not a car to buy if you're looking for thrills on winding back roads.

Where Is the 2021 Genesis G90 Built?

Hyundai builds the 2021 Genesis G90 in South Korea.

Which Genesis G90 Model Is Right for Me?

The 2021 Genesis G90 comes in two trims: 3.3T Premium and 5.0 Ultimate. We recommend the base model, since it comes with a long list of standard equipment, and its 365-horsepower twin-turbocharged V6 engine is plenty powerful. The G90 Ultimate has a 420-horsepower V8 engine and just a few additional features, so it probably won't be worth the several thousand dollar markup for most buyers.

Both G90 trims come standard with an eight-speed automatic transmission and rear-wheel drive, with all-wheel drive (AWD) optional for $2,500.

Genesis G90 3.3T Premium

The 2021 Genesis G90 3.3T Premium starts at $72,950. Standard features include Nappa leather upholstery, power-adjustable front seats, heated and ventilated front seats, heated rear seats, tri-zone automatic climate control, a sunroof, interior ambient lighting, power soft-closing doors, and power rear-window sunshades. The base model also includes an electronic adaptive suspension, proximity keyless entry, remote start, a hands-free power trunk lid, an auto-dimming rearview mirror, a universal garage door opener, and a 7-inch digital instrument cluster display. Also standard are a heated, leather-wrapped, and power tilt-and-telescoping steering wheel, along with memory settings for the front seats, steering wheel, and outside mirrors.

The standard infotainment system includes a 12.3-inch touch screen, a 17-speaker Lexicon surround-sound stereo, wireless device charging, navigation, a satellite radio, HD Radio, Android Auto, Apple CarPlay, Bluetooth, and multiple USB ports.

Standard driver assistance features include forward collision warning, forward and reverse automatic emergency braking, pedestrian detection, lane departure warning, lane keep assist, lane tracing assist, blind spot monitoring, a blind spot camera, rear cross traffic alert, highway driving assist, and navigation-based adaptive cruise control.

The G90 also comes standard with a surround-view parking camera system, automatic high-beam headlights, front and rear parking sensors, rain-sensing windshield wipers, a head-up display, driver attention monitoring, and safe exit assist.

Genesis G90 5.0 Ultimate

Starting at $76,700, the G90 Ultimate adds a rear-seat entertainment system with two 10.3-inch touch screens, along with power-adjustable, reclining, and ventilated rear seats with memory settings.

The Final Call

If you're in the market for a luxury large car, the 2021 Genesis G90 should be near the top of your list. It bests many rivals with its combination of interior opulence, supple seating, easy acceleration, and breadth of features.

Don’t just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "The 2021 G90 sedan delivers a cossetting ride and limo-like cabin but does so at a price that undercuts established rivals by thousands of dollars. … The G90's front and rear seats are plush, spacious, and comfortable, and the cabin boasts plenty of standard luxury and convenience features." -- Car and Driver
  • "It's not the same as a Mercedes S-Class. And now that it's not trying to be, it's a much better car." -- Road and Track (2020)
  • "The G90 is a solid car and a solid value, more people just need to know it exists. So maybe it's good that the G90 looks the way it does. That huge grille might not be for everyone, but it'll certainly turn heads -- just in time to see the big Genesis badge on the trunk." -- CNET (2020)
