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

Low teens in town, and 24mpg tops on the highway make this a less than ideal economy car. see full Pontiac G8 review

Not bad mileage figures given the size of the car and the beast of an engine, but this is not a car for the hybrid set. see full Pontiac G8 review
