How does awd work in gmc acadia?

Answer 1

The Acadia AWD system is set up to deliver a 90/10 torque split (90% to the front wheels) in normal operation. When detecting front wheel slippage it can transfer as much as 35% to the rear wheels. So on a steep incline it would indeed be better than FWD. Not much sense to have an AWD system that delivers all torque to only one differential as the previous poster seemed to indicate.
