2015 GMC Yukon Denali What is the meaning of BASE and AWD trim?
1 Answer
Base is no-frills, few if any optional equipment, AWD All-Wheel-Drive, not to be confused with 4X4 or 4 wheel drive. AWD is all the time, you can't take it out, the wheel speed sensors detect if a wheel is slipping, turning faster that it should be compared to the speed of car and other wheels, and 4WD you can drive in 2WD mode by choice
