What is On-Demand Four-Wheel Drive?

[VanessaFitz]

On-Demand Four-Wheel Drive: A drivetrain system that only switches to four-wheel drive when appropriate, otherwise remaining in two-wheel drive. The system automatically shifts between two-wheel and four-wheel drive modes based on the vehicle's driving conditions without requiring manual intervention. Also known as Real-Time Four-Wheel Drive, this technology has been developed in recent years and uses a computer chip to control the switching between two-wheel and four-wheel drive. A notable feature of this system is that it inherits the advantages of both full-time four-wheel drive and part-time four-wheel drive while compensating for their shortcomings. It can autonomously identify driving conditions and control the switching between two-wheel and four-wheel drive modes based on changes in the driving environment. On low-traction surfaces such as bumpy, hilly, or winding roads, the vehicle automatically sets to four-wheel drive mode, while on flatter surfaces like urban roads, it switches back to two-wheel drive.
