CAPABLE FOR OUT-OF-TOWN TRAVEL
To make the Hyundai Tucson even more versatile, Hyundai engineers added an advanced electronic AWD system designed by JTEKT. The AWD system will automatically activate under any driving condition when needed, distributing the power equally and optimizing driving performance. Under normal driving, the system only distributes power to the front wheels thereby reducing fuel consumption. The system includes a driver-selectable AWD lock allowing for a 50/50 torque split between the front and rear wheels for off-road and very slippery conditions.
For even more driver control, the 2010 Tucson features Hyundai's first Hillstart Assist Control (HAC) and Downhill Brake Control (DBC). HAC is designed to minimize rolling backwards on steep ascents. By selecting the DBC switch, the Hydro-Electronic Control unit manages the wheel speed sensors, steering angle sensor and acceleration sensor to maintain control and speed on steep declines without having to use the brake. Neither of these controls are available on CR-V, Escape or Rogue and are typically found on luxury SUVs with much higher price tags.
