Is the Highlander a Full-Time Four-Wheel Drive?
1 Answers
The Highlander is not a full-time four-wheel drive; it is an on-demand four-wheel drive. Here is more relevant information: 1. Four-Wheel Drive: Four-wheel drive refers to a vehicle maintaining a four-wheel drive form throughout the entire driving process. The engine's output torque is distributed to the front and rear wheels in a fixed proportion. This driving mode can provide better off-road and handling performance at any time, but it cannot adjust torque distribution according to road conditions and has higher fuel consumption. 2. On-Demand Four-Wheel Drive: On-demand four-wheel drive is controlled by a computer chip to switch between two-wheel drive and four-wheel drive. On normal roads, the vehicle runs in two-wheel drive mode. When encountering off-road conditions or wheel slippage, the computer will detect and automatically distribute power to the other two wheels. For the part-time four-wheel drive mode, the quality of the control program affects the intelligence of the drive mode switching. In addition, there is also a part-time four-wheel drive (Part-Time 4WD) where the driver manually controls the switching of the drive mode. Many SUVs and off-road vehicles have one or more of these four-wheel drive modes to complement each other's strengths and weaknesses.
