The new G90 is a new-year model based on the 2021 4th generation full change model and is the first Korea-mass-produced model equipped with Level 3 autonomous driving technology.
The HDP function is a technology that corresponds to Level 3 of the five levels of autonomous driving classified by the Society of Automotive Engineers (SAE). A Level 3 car can run on its own at a speed of up to 80 kph on car-only roads such as highways. Hyundai Motor Group initially tried to release the G90 in the fourth quarter of 2022, but delayed the release to the first half of this year by increasing the speed of HDP application from 60 to 80 kph.
Level 3 autonomous driving is considered the beginning of autonomous driving because it is the first step in which control of a vehicle is transferred from the driver to the autonomous driving system.
Hyundai Motor Group added a LIDAR sensor to the front grill for HDP operation of the 2023 G90. HDP works in connection with LIDAR, rear, side, and front cameras and front and side radar.
