Common Questions
What is the difference between AWD and 4WD?
AWD operates automatically and continuously. You never have to think about it. 4WD is driver-selectable and includes a low-range gear for technical off-road situations. AWD is for everyday traction. 4WD is for serious terrain.
Is AWD or 4WD better in snow?
For city and suburban snow, AWD is more convenient since it activates automatically. For deep snow, steep grades, or off-road winter driving, 4WD with low range gives more torque. The real answer: good winter tires on any drivetrain beat all-season tires on AWD or 4WD.
How much more does AWD cost vs 4WD?
AWD typically adds $1,500 to $3,000 at purchase and $200 to $500/year in fuel. 4WD adds $2,000 to $4,000 and needs transfer case service every 30,000 to 60,000 miles. Over 5 years, both add $4,000 to $8,000 to total ownership cost.
Can you use 4WD on the highway?
4WD High is fine at normal speeds on slippery roads. 4WD Low is only for crawling - never above 25 mph. Never use part-time 4WD on dry pavement; it causes drivetrain binding and can damage the transfer case. AWD has no such restriction.
