Howdy, I'm in the market for a new Car. I tend to buy the engine first. I currently own a 2001 pontiac Grand prix GT. I has the 3.8 L 90 deg. V6. In the real world I get about 23 city and about 28 hwy. I love this car, It is a great combo of performance and economy. Plus it's durable I have about 197k miles on it and still going strong. I have driven the impala 06 with both the 3.5 and 3.9. I like the power with the 3.9 however I'm concerned about the milage Being a Gm/domestic buyer with 2k on my Gm card I will definately buy some gm product. So if you own an impala with either the 3.5 or 3.9. I would like to here about your (after breakin milage) Thanks Jfcnet (el Paso,tx)

I had a 2001 Monte Carlo SS that got great mileage close to the sticker (28-31 HWY) with great performance, fit/finish and handling! I felt I had to trade it at 100K as the warranty was up. The new Impala SS get's terrible mileage (22 tops expressway, no wind, no hills, no traffic, 69MPH average over 200 miles)! The mileage seem's to be stuck around 19-22 both in town and out. The driver and trips have not changed, just the car. The "EPA" sticker was virtually the same for both cars. The performance, like the mileage, is not as good as other choices. The fit and finish is bad as well along with bad heated seats, windshield washers, side and roof trim falling off, inner-fender wells gaping, etc. I have even had the folks at GM corporate here in MI involved (including the platform mgr. and a marketing person)! All I have gotten is gee that's too bad, don't you like the exhaust sound though. Is any body else getting this run around after paying good money? After 7K+ miles I really miss my old MC SS!

Replying to: realcarguy (Mar 04, 2006 5:11 pm) In my SS, I'm averaging about 15 mpg in town driving. This is with 93 octane gas and a decent amount of "pushing the pedal down".... I am also not real happy with this number. I haven't taken many highway trips yet, but when I have I've averaged about 23-26 mpg with the cruise set on 68 most of the time. My car doesn't have ANY trim issues. Everything fits well, and nothing is falling off. Actually, after 2500 miles, I haven't had any problems with the car, including the seat heaters. Just like any car, it's possible to get a lemon. Not to belittle RealCarGuy's experience, but I don't think his SS is representative of the car in general. John |

| 2004 Impala LS, 13,000 miles, 3.8 V6. This is not my car, but my grandma's, and we both love to drive it! She usually averages 27-28 mpg normal driving. Lives in rural hilly area, so she's happy with those numbers. Took a trip to Kentucky, did about 350 miles worth of driving (interstate, city streets, hilly 2-lane byways). Got 31.3 mpg!! Couldn't be happier with a full-sizer that gets better than 30!! | |
I'm getting between 16.5 and 18 mpg with mixed driving. Comparing the actual mileage to the car's computer, is very close. The computer usually calculates about .5 mpg less than my calculations. It is within the margin of error since I can't be sure I'm getting an exact amount of fuel in the tank during fill-up. It's much more accurate than my '02 Monte Carlo SS.

I am getting the same 16.5 to around 19 in town. On the freeway I can go about 325 miles on a tank of gas I think that adds up to around 21-23 mpg not what they claim on the sticker. I think it will take my grandfather driving the car to get the mileage they claim on the sticker!

I have a 05 Impala. The question I have is. I live in WI. but the car has California emission's on it. Should I exspect better , worse or the same mpg. then a standard emission car ? Right know the best I get on the hwy. with the curse lock at 69 is 25 mpg. not what I espected. |

Just thought I'd post an update and some tips. I just finished an 1,100 mile roadtrip and managed to squeak out just over 25 mpg (25.34) in my '06 SS. I experimented a lot on the trip and have found that I can usually keep DOD activated at speeds up to 75 mph by following almost any vehicle with up to a 3-5 second following distance. Obviously 18-wheelers have the largest wake but SUVs and other mid or full-size cars seem to create enough of a wake to maintain DOD activation. Even better, traveling behind a group of vehicles. I found that trying to keep the DOD engaged helped alleviate the stress I normally feel when people insist on driving side-by-side and blocking the passing lane. Some may think I'm following too closely but I assure you, I was keeping a more-than-adequate following distance, usually 2 to 3 seconds. The hardest part was finding someone travelling at a consistent speed although I was usually able to find a "buddy" or two traveling at 75 mph. A final note, I could even maintain up to 80 mph (with DOD) as long as I had a large truck or group of cars to follow or even intermix with. But, not many seem to use their cruise control consistently over 75 mph. My experimenting helped keep me occupied during the long and boring stretch of I-10 between Pensacola and Jacksonville, FL. It also kept me from getting too heavy-footed.
