The SDV benefits of the Elantra are limited to the experience layer: OTA of major controllers, app selection options, and AI-based voice control. Meanwhile, costs are already being incurred. Hyundai Motor acknowledged that electrical loads increased due to the SDV transition, and to offset this, multiple engineering improvements in aerodynamics, air conditioning, and regenerative braking were implemented, which somewhat diluted the fuel economy improvement. SDV promises 'a vehicle that will be updated longer' rather than 'a better vehicle,' but structural uncertainty remains regarding the undisclosed software support period.
