Can AWD be used when driving on the highway?

[DeJameson]

AWD can be used when driving on the highway, as it is suitable for low-load conditions and can perform effectively at high speeds. The center differential lock in an AWD system uses a multi-plate clutch structure, similar to a manual transmission clutch. Once engaged, it transfers power to the rear wheels. This type of multi-plate clutch center differential is compact, electronically controlled, and commonly used in family vehicles. AWD automatically switches to four-wheel drive only when necessary, otherwise remaining in two-wheel drive. It adjusts between two-wheel and four-wheel drive based on road conditions without requiring manual intervention. Unlike part-time 4WD, which requires manual switching between two-wheel and four-wheel drive, and full-time 4WD, which operates in four-wheel drive under all conditions, AWD is designed for automatic adaptation.
