2018 Genesis G90: What's New, Specs & Features
Last updated August 4, 2026
For 2018, the Genesis G90's main change is that steering-responsive full LED headlights became standard across the range, newly upgrading the 3.3T Premium. Otherwise, this was a light equipment update rather than a redesign.
About the 2018 Genesis G90
1st generation (2017-2022 U.S. model years), second year; minor equipment update before the major 2020 redesign
The G90 is Genesis’s largest luxury sedan, built around a quiet ride, generous passenger space, and extensive standard comfort and safety equipment. Its identity centers on long-distance comfort rather than sharp sports-sedan handling. A smooth adaptive suspension, richly trimmed cabin, strong V6 or V8 power, and unusually complete front- and rear-seat amenities distinguish it from full-size luxury sedans that often separate similar hardware into option packages.
The 3.3T Premium is a well-equipped large luxury sedan with a 365-hp twin-turbo V6, adaptive suspension, Nappa leather seats, a 12.3-inch navigation screen, and a broad set of driver-assistance features. The 5.0 V8 trim focuses more on rear-seat comfort, with power-adjustable heated and ventilated rear seats plus two 10.3-inch entertainment displays.
