Trying to determine if opting for the AWD version of the Blazer is worth the money. The least expensive version of the Blazer with AWD starts at $37,195, which is about 5 grand more than a Murano or Edge with AWD. The cost to add this varies based on trim level too. It appears that the RS and Premier get a more sophisticated version of AWD that comes with a twin-clutch rear differential and the ability to shift torque between the rear wheels. The more basic setup can disconnect power to the rear wheels to help save on gas.
