What is On-Demand Four-Wheel Drive?
1 Answers
On-demand four-wheel drive refers to a system where the car primarily operates in two-wheel drive under normal conditions. When a wheel slips and the vehicle cannot move forward, it automatically switches to four-wheel drive. This system automatically shifts between two-wheel and four-wheel drive based on driving conditions without requiring manual intervention. Here is more information about on-demand four-wheel drive: 1. On-demand four-wheel drive differs from part-time four-wheel drive, which requires manual switching between two-wheel and four-wheel drive, and full-time four-wheel drive, which operates in four-wheel drive under all conditions. 2. Since its inception, on-demand four-wheel drive has evolved through roughly three stages, with each stage featuring distinct structures and performance. Initially, due to technological limitations, vehicles equipped with on-demand four-wheel drive could not match the performance of full-time four-wheel drive, whether in terms of off-road capability or handling limits. Their performance was only intermediate between two-wheel drive and full-time four-wheel drive. With advancements in on-demand four-wheel drive technology, the third generation has seen significant improvements in performance, along with substantial changes in its working principles.
