We have a 2008 AWD Edge Limited. It is a fantastic vehicle BUT the mileage is brutal. The computer says that we are using 16.0 litres/100km. The dealer checked it and said we were using 14.7 Litres/100km which is better but still sux. My wife drives the car to work and back, mostly city but this is still not great. She is not a lead foot. Am I alone or is this fuel consumption usual? Ted
