What is the Genesis G80?

The G80 is a large luxury sedan at the heart of Genesis’s saloon range, between the smaller G70 and flagship G90. Its four-door cabin gives it a more spacious, comfort-focused character. Genesis became a standalone brand in 2015, with a design identity shaped by details such as the crest grille and two-line lamps inspired by its winged emblem.

The first generation listed as G80, code DH, ran from 2017 to 2020. The second generation, code RG3, began in 2021 and continues today. The later car brought a fresh interpretation of Genesis design, including the crest grille and two-line lamps.
