These photos of the sedan's front and rear were originally posted on Korean website BobaeDream, and show a Korean market version - to be known as the Genesis EQ900 - waiting around for its publicity photos to be taken.
Despite their low resolution, these photos show us all the key details of the car's exterior styling. At the front, the G90 will feature a front end that's closely modelled on the Hyundai Genesis that was launched locally earlier this year, with a tall familial six-point grille flanked by swept back headlights.
Around the sides and tail, though, the G90 is a lot more formal than the smaller and more dynamic Hyundai Genesis.
The sides themselves seem to be more upright, although they are enlivened by a thick-cut character line. The car's large rear doors point to a passenger-centric focus.
At the rear, the G90/EQ900 shows a clear lineage to the Hyundai Equus that it's set to replace.

Hyundai says that it plans to release five new Genesis models by the end of the decade, including two sedans, two SUVs, and a coupe. Some of these seem likely to end up down under, but the G90 is unlikely to make the journey for now.
According to Bill Thomas, Hyundai Australia's communications chief, the G90 “hasn’t been ruled out” for Australia, but its appearance down under would be “very unlikely” due to the “significant investment required to engineer for right-hand drive”.
