2009 4dr Sedan 211-horsepower 3.5L V6
4-speed automatic FWD		 Averaging 25.0 mpg in mixed driving, very good for the size of the vehicle and the the fact that it is a V6. see full Chevrolet Impala review

4-speed automatic FWD		 Fuel Economy beats smaller sized cars, let alone others in the same class. 30mpg is not hard to attain. see full Chevrolet Impala review

2008 4dr Sedan 211-horsepower 3.5L V6
4-speed automatic FWD		 If driven carefully, 22-30 MPG around town and 33-36 MPG highway. If you are a sloppy driver, make that 18-20 and 25 MPG. see full Chevrolet Impala review

2012 4dr SUV 288-horsepower 3.6L V6
6-speed shiftable automatic FWD		 I purchased this vehicle in April of 2012,new with less than 25 miles showing. My wife drives this car to work each day, round trip is approx 30 miles. She is averaging 17 mpg, but on trips I drive and can average 22-23 mpg. I usually cruise the interstate at 70-80 mph. and I do use the cruise control. The mpg will vary but I have seen a high of 25 and a low of 21. Overall very pleased with the ride and comfort, when traveling there are usually 3 adults and luggage. see full GMC Acadia review

6-speed shiftable automatic FWD		 Love the fuel economy of the Acadia... we get 19-22mpg in town.. and 22-26mpg on the interstate. Vehicle speed really affects the mileage attained. We get the best mileage at 55-60mph... it really drops when doing 70-80mph.. see full GMC Acadia review

6-speed shiftable automatic AWD		 Even with conservative driving over long distance, was not able to get close to EPA MPG.
