How does a full-time four-wheel-drive (4WD) system differ from a part-time 4WD system when driving on dry asphalt?

Full-time 4WD uses a center differential to prevent driveline binding during cornering. Full-time 4WD locks the front and rear axles together permanently. Full-time 4WD must be manually disengaged above 50 km/h to prevent transfer case explosion. Full-time 4WD sends 100% of the engine torque to the front axle only.

Correct Answer:

Full-time 4WD uses a center differential to prevent driveline binding during cornering.
