Is the Role of On-Demand Four-Wheel Drive Significant?
1 Answers
On-demand four-wheel drive plays a significant role. The primary function of an SUV's on-demand four-wheel drive system is to automatically switch between two-wheel drive and four-wheel drive modes based on the vehicle's driving conditions, eliminating the need for manual operation. Extended information: 1. Full-time four-wheel drive is superior to on-demand four-wheel drive. Full-time four-wheel drive offers multiple modes such as high-speed four-wheel drive and low-speed four-wheel drive, enabling easy escape from challenging road conditions. However, full-time four-wheel drive operates in four-wheel drive mode at all times, resulting in higher fuel consumption and requiring manual switching of four-wheel drive modes. 2. The four-wheel drive version of the same vehicle model is more expensive than the two-wheel drive version, and the four-wheel drive mode of ordinary urban SUVs is typically tuned to provide greater driving force to the front wheels and less to the rear wheels.
