what fuel economy? bought it to pull a Brenderup horse trailer (3300lbs including 1 horse) that can be pulled with a 4cyl car in europe.... doing 22l/100km on flat roads with light foot. more than double combined rating ....GM unresponsive! see full Chevrolet Avalanche review

It only averages around 14 to 15 in a mostly city driving environment. Was hoping the V4 mode would kick in more often to help improve the economy. see full Chevrolet Avalanche review

It is great for such a big car. 30 mpg is pretty easy for highway cruising, and mixing driving will do 24-25. see full Mercury Montego review

A large car that gets over 20 MPG in city driving is great. The 29 MPG highway rating is nice, but the car is mainly used as a grocery getter / errand runner. see full Mercury Montego review
