2012 4dr Sedan 300-horsepower 3.6L V6

I got 468 miles on a tank of gas from Greenville TN to Charleston SC then to Myrtle Beach. Very impressed
2011 4dr Sedan 211-horsepower 3.5L V6
4-speed automatic FWD
So far so good with E10 Fuel I am getting an average of 27 and I only have 500 miles on it so far. I now have over 3000 miles and just got back from a long trip 1/2 of it hilly. I set the cruise on 67 and let it go averaged over 32mpg by the end of trip
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.
2008 4dr Sedan 233-horsepower 3.9L V6
4-speed automatic FWD
Mileage averages 23-24 around town and close to 30 on road trips which is quite good considering engine size and power.
2008 4dr Sedan 211-horsepower 3.5L V6
4-speed automatic FWD
Fuel Economy beats smaller sized cars, let alone others in the same class. 30mpg is not hard to attain.
2008 4dr Sedan 211-horsepower 3.5L V6
4-speed automatic FWD
Its a full size car that gives good performance and still gets 30 MPG on the highway.
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.
2007 4dr Sedan 233-horsepower 3.9L V6

15 in town. 30 highway
2007 4dr Sedan 211-horsepower 3.5L V6

2004 2dr Coupe supercharged 240hp 3.8L V6

25 cty & 30 hwy what more could you ask for in a car the will go 145mph and 14 second 1/4 mile times.
2004 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD
20 mpg in the city is acceptable for a larger car.
2003 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD
For such a large car, the fuel economy is amazing. Like most vehicles, if you drive it hard the economy is poor. However, if you can drive sensibly on the highway at about 105 kph or 65 mph it will easily get over 30 mpg (38 mpg Canadian)!

Less then 25 MPG average
2008 4dr Sedan 233-horsepower 3.9L V6

In town mileage is less than 15 mpg.
2007 4dr Sedan 233-horsepower 3.9L V6

Only get about 25 mpg on interstate with the 3.9 Active fuel management is a gimmick in my opinion and older GM cars with a V6 I have driven have been better with fuel economy than the 3.9.
