How does the 19 Edge AWD differ from what was used in the past? It is described as "AWD disconnect" so does that mean it operates as FWD until AWD is needed? Will this decrease the mileage penalty for AWD vs. FWD? Does the driver control the disconnect? We have a 13 Edge FWD and are considering a 19 Edge and trying to decide if the added cost and mileage penalty are worth it. We live in the Midwest and have a 4X4 F150 when things get really bad.
