Abstract
An all-wheel-drive vehicle includes a primary drive axle, a secondary drive axle, and an all-wheel-drive powertrain configured to selectively power the primary and secondary axles. The powertrain includes a powerplant and a clutch that couples the powerplant to the secondary axle when engaged and that decouples the powerplant from the secondary axle when disengaged. A controller is programmed to disengage the clutch to disable all-wheel drive and propel the vehicle solely with the primary drive axle based on repeated occurrence of power output of the powertrain being less than a value.
