Used 2023 Genesis G90

SUVs are becoming ubiquitous, but there are still a few options for drivers looking for a full-size, flagship luxury sedan. The Genesis G90 is one of the most competitive players in this shrinking class, and it goes toe-to-toe with longtime class leaders like the BMW 7 Series, Audi A8, and Mercedes-Benz S-Class.

The G90 has a unique design that turns heads, and the interior is spacious and supremely luxurious. This Korean-built luxury sedan is available in two configurations. The base model is loaded with Nappa leather seats, a twin-turbo V8, and a digital gauge cluster. The upper trim adds features like an electric supercharger, reclining and massaging rear seats, and air suspension.

The Genesis G90 is powered by a 375-hp turbocharged V6 engine matched with an 8-speed automatic transmission and all-wheel drive. It’s available with a 409-hp E-Supercharged V6, also with all-wheel drive.

With confident acceleration, we found the turbo V6 engine satisfying in city and highway driving. The standard AWD system helps keep the power delivery smooth and consistent, and it maintains good traction in all weather conditions.

The boost from the optional electric supercharger is the most noticeable low in the rev range. We noticed it gave the G90 more oomph when accelerating from a standstill with a brisk 0-60 mph time of 5.1 seconds, and it had the same good manners on the highway as the base engine without the supercharger. Another big perk; the auto start/stop function is much smoother with the supercharger.

The suspension and steering deliver a luxurious ride without feeling floaty or sloppy, and it was an absolute pleasure to drive in our testing. In addition to the engine upgrade, the E-Supercharged trim improves comfort and handling with a multi-chamber air suspension system and 4-wheel steering.

We’ve spent hundreds of hours driving and evaluating the current collection of full-size luxury sedans, including this Genesis G90.

Fuel Economy

The G90 is rated at 21 combined mpg with the standard powertrain. Upgrading to the E-Supercharged trim comes with an almost negligible fuel economy penalty; it gets 20 combined mpg, according to the EPA. Premium gas is recommended for both powertrains.

The fuel economy of the G90 is similar to the Lexus LS (when equipped with AWD) but worse than the most efficient variants of its German rivals.

The interior of the Genesis G90 is spacious and luxurious. There’s lots of legroom in both rows of seats, with plenty of room for the rear-seat passengers to stretch out. The interior design justifies the price tag, and the quality of the materials is top-notch.

Standard interior features include Nappa leather seating, matte-finish wood trim, a microfiber suede headliner, heated, ventilated, and massaging front seats with power bolsters, heated rear seats, a heated steering wheel, 3-zone climate control, power rear sunshades, a head-up display, and a wireless charging pad.

The standard infotainment system is a 12.3-inch screen complemented by a digital gauge cluster the same size. It’s loaded with navigation, Android Auto, Apple CarPlay, SiriusXM, HD Radio, and a Bang & Olufsen audio system.

The upper trim gets more luxurious inside with a 3D audio system, a rear center console with touchscreen controls and wireless charging, plus ventilated, reclining, and massaging rear seats.

The 2023 Genesis G90 has a striking exterior design that won’t blend in with the crowd. Some of this luxury car’s rivals are good if you’re looking for subtlety, but if you want a premium sedan that stands out, the G90 can’t be ignored.

The G90 is the biggest sedan in the Genesis lineup. It’s a full-size sedan with dimensions similar to thos of the Mercedes-Benz S-Class, Audi A8, and Lexus LS.

1. Available E-Supercharger
The optional electric supercharger is a welcome addition to the twin-turbo V6 under the hood of the G90. It boosts performance with an extra 34 horsepower and 14 lb-ft of torque over the base engine with only a slight penalty in fuel economy.

2. Virtual Venues Live
This enhanced audio system is a virtual, 3D-surround sound function optimized for different types of music. It has settings like Boston Symphony Hall and Bang & Olufsen Home, replicating the sound quality of real-life venues to make the most out of the 26-speaker sound system.

3. Opulent rear seats
The front seats in the G90 are supremely comfortable, but the rear seats are arguably an even better place to be. Nappa leather seating is standard, and the upper trim of the G90 adds heated, ventilated, massaging, and reclining rear seats, plus a rear center console with touchscreen controls and a wireless charging pad.

4. Mood Curator
This standard feature allows your passengers to set the mood in the G90 with themes like Vitality, Delight, Care, and Comfort. It enables integrated control of ambient lighting, the sound system, the fragrance system, seat massagers, and power sunshades to create different ambient environments.

5. Genesis Digital Key 2
This feature turns your iPhone, Apple Watch, or Samsung smartphone into a key through Apple Wallet and Samsung Pass. It does more than just unlock and start your Genesis. The car recognizes the driver and loads your customized vehicle preferences.

6. Highway Driving Assist II
This standard semi-autonomous driving system makes highway driving safer and more relaxed by combining features like adaptive cruise control, lane centering, and road sign assist.

The base engine in the 2023 Genesis G90 is a powerful twin-turbocharged V6. It produces more power and torque than the base V6 in the outgoing G90 while returning better fuel economy.

The V8 in the outgoing G90 is no longer available. In its place is a twin-turbo V6 equipped with an electric supercharger. It improves performance without only a slight hit to the fuel economy.

Every G90 has an 8-speed automatic transmission and all-wheel drive.
