Have had my 07 Impala about a week. It's the 3.5L. At this point, in heavy stop and go traffic with the AC running at least half the time, I am still averaging a little over 25 mpg. I'm sure if I were able to drive highway most of the time, it would get over 30. In a few weeks, I'm taking it on a weekend trip that will be mostly highway driving - I'll make sure to see what it's doing then.

My guess is they're talking readout on the DIC while briefly cruising at 60 MPH on the Interstate, not an average on a complete tank.

My mileage is now down a bit from my previous assessment. At a steady 60 mph on a flat highway with 5,000 miles on the car am getting 28-29 mpg. Still very good and in keeping with the EPA estimates. I do note that if driving up steep hills the mileage decreases which I'm sure it would in any car. After a year of ownership I haven't had one problem with the car save for the power steering assembly recall (covered under warranty) which never did result in a leak of fluid in my particular car. I remain very satisfied with the vehicle overall and think it provides superb and optimal value for the money. Love the power, smooth auto transmission, quiet and comfortable interior, throaty but not overbearing exhaust note and the excellent BOSE audio!

recent rental MPG by mtpete

1600 mile round trip, 2007 Impala, 3.5 engine.
 
Returned 32-34 mpg per tank. Best tank, 640 miles. Kept speeds at posted limits of 65/75 mph, moderate acceleration, full use of cruise control.
 
Impressed with smooth powertrain, and, amazingly, comfort... no back pain after a 14 hour drive!
 
Now if they'd just tighten up that suspension. Not confidence inspiring at highway speeds.
 
And where's that new 2.9 diesel V6?
 
This is excellent mpg for a car of this size. Chevrolet is so very close to earning my business.

2006 Impala w/3.5 @ 9,800K Miles by lightning23

Freeway driving: Cruise set 70 MPH yields 32.5MPG. Results are even better in the 60 to 65 MPH range - anywhere from 34ish to as high as 37/38 MPG.
 
In town: driven primarily for short distances of 1-4 miles = 22MPG average.
 
As the previous poster stated: smooth powertrain and comfortable ride. We are very satisfied with the vehicle. Best car we've owned, as of yet!

Mileage... by ryster

'06 Impala, 2LT, 3.5L V6. 11 months and 14,000 miles "old".
 
Average 21mpg most tanks. Car is a daily driver during the week, around 60 miles per day. Mixed commute, some steady 55mph driving, some stop and go, some 35-45 suburban driving. Lots of hills.
 
I have been "experimenting" recently and driving VERY conservatively. Very gradual acceleration, no mashing the gas, etc. So far this tank I am averaging 23. So I gain 2mpg if I drive like this. Without all of the hills I could probably get up to 25mpg overall.
 
The car has never really been on a 100% highway trip for a full tank. I did do a 100 mile round-trip highway run several months ago, and saw about 26mpg for that 100 miles.
 
All in all, a very economical car compared to my previous V8 SUV. My monthly fuel bill has almost been cut in half since I bought the Impala

2006 LTZ Mileage by deminin

We've had our 2006 LTZ, with the 3.9L V6 for about 22 months now, and it has been flawless. We recently drove out to Las Vegas from central Missouri, and on the way back I tracked the mileage. I zero'd everything out when we left Las Vegas, and stopped checking at Springfield, Missouri. Running on I-40 and I-44 at 75 to 80 miles per hour with the AC running, I got 30.1 MPG during that 1200 mile stretch. Needless to say, I was impressed. On a daily average, mostly 2 lane country roads, we get between 26 and 28, which for a car of this size still isn't too bad.
