Hyundai Wia has successfully developed a locally produced four-wheel drive (4WD) system that optimizes power distribution for various terrains.
On Thursday, Hyundai Wia announced the mass production of its newly developed 2-speed Active Transfer Case (ATC), a rear-wheel-based electronic 4WD component that dynamically adjusts power distribution based on driving conditions.
The 2-speed ATC optimizes traction by seamlessly distributing power between the front and rear wheels of rear-wheel-drive (RWD) vehicles. Hyundai Wia is the first South Korean company to develop and mass-produce this technology, which will be featured in its pickup truck, the Tasman.
Designed for superior stability in all conditions, the 2-speed ATC offers four selectable driving modes: 2 HIGH, 4 AUTO, 4 HIGH, and 4 LOW.
The system continuously analyzes road conditions and driver input, recalculating power distribution every 0.01 seconds to ensure optimal performance.
To validate the 2-speed ATC’s reliability, Hyundai Wia conducted extreme-condition testing across multiple global locations. Trials included rugged mountain roads in South Korea, desert endurance tests in California and the United Arab Emirates (UAE) to assess high-temperature and sandy terrain performance, and cold-weather evaluations in northern Sweden, where temperatures drop to -22°F (-30°C). In Sweden, engineers specifically tested the 4 LOW mode on a 30-degree snow-covered incline.
With the launch of the 2-speed ATC, Hyundai Wia now offers a complete 4WD lineup and aims to expand its footprint in the global automotive market. A company spokesperson stated that their goal is to deliver superior driving performance on all terrains. Through continued innovation, they will strengthen their presence in the global automotive parts industry.
