Optimal performance under the slippery road or off-road conditions
Stable and safe off-road driving with 4WD
HYUNDAI TRANSYS EST(Part-time transfer case) is equipped with the originally designed 1-cam 2-shift structure switching unit for improved prompt response. Safe driving is guaranteed by a simple and quick touch of the switch to change the driving mode when the road suddenly becomes rough.
4WD low mode offers improved pulling capacity and enables safe escape from rough roads. It achieved less-noise and more-efficient performances with the know-how of planetary gear designs. 4WD SUV and MPV vehicles ensure safe driving under extreme off-road conditions and better pulling capacity even with heavy loading. CAN communication EST(Part-time transfer case) controls are equipped with a control logic system to protect driving systems when drivers misuse vehicles.
