2021 Genesis G90: What's New, Specs & Features
Last updated August 4, 2026
The most important change for the 2021 Genesis G90 is a new Rear Comfort drive setting that makes acceleration gentler for rear passengers. Improved voice recognition is the only other notable update after the larger 2020 refresh.
About the 2021 Genesis G90
1st generation (2017-2022), second year after the major 2020 restyle
The G90 is Genesis's largest and most comfort-focused sedan, built around a quiet cabin, a soft controlled ride, generous passenger space, and an unusually long list of standard luxury and driver-assistance features. Its strongest distinction is that many amenities requiring packages on competing full-size luxury sedans were factory-installed across the range. The 2021 model emphasizes relaxed long-distance travel and rear-passenger comfort rather than sharp, sporty handling.
The 3.3T Premium is a well-equipped luxury sedan for an owner-driver, with a 365-hp twin-turbo V6, adaptive suspension, Nappa leather, and a 12.3-inch navigation display. The more passenger-focused 5.0 trim has a 420-hp V8, reclining and ventilated power rear seats, and dual rear entertainment displays.
What changed, by category
Structural
A Rear Comfort drive setting was added to both trims. It adjusts vehicle responses to make acceleration gentler for rear passengers, without changing the underlying chassis.
Tech
Voice recognition was improved to understand more natural conversational commands.

2021 Genesis G90 Reviews

2021 Genesis G90
(90 reviews)
“The Genesis G90 is an amazing vehicle - specifically useful for those that drive long highway trips. The power is fantastic and the overall vehicle is extremely smooth. The car has two major drawbacks, in my opinion. The low-beam headlights are poor and provide very little illuminated distance. And the car has a very low ground clearance. They are the only drawbacks that I have found with the vehicle overall.”
“It is a large sedan. It is solid and heavy. It is comfortable and roomy. It has more power than I normally need but it's plenty if I need it! It handles well but is easy on your passengers. It is quiet, but can be quieter as the luxury cars of the 50s and 60s.”
