It is possible that the new engine doesn't do as well with the extra weight and taller gearing of the Maxx as the old LX9. That mixed with altered EPA guidelines and then the extra load of a p/s pump on the 07 models probably accounts for the decreased mileage.

Our 2004 LS (purchased new in January 2005) turned 22,000 miles as we completed our 2,500 mile road trip from Norman, OK, to Mount Rushmore last week. We averaged right at 28mpg (manually calculated) with a lot of 75mph+ and some stop-and-go for scenic turnouts. The car performed flawlessly.

Am curious how the 2007's are doing...
 
Also, one web source claimed the LZ9 engine the SS version is using has, for 2007, active fuel management.
 
I've not seen that in any '07 Malibu literature. Do the '07 SS's actually have this?

Just picked up my 2006 LTZ Maxx Friday. Yesterday drove 190 miles in heavy winds (unfortunately no tail wind) and averaged 27.9 MPG, which I was very pleased with.

...was that the SS Impala with the V8 engine was rated at 18 mpg City, ..vs.. the Malibu Maxx SS rated at 17 Mpg for the city. There were similar differences for Highway mileage.
 
We have a small block 305 HP V8 here getting better mileage than a 240 HP V6. I'm frankly amazed how bad the Maxx SS mileage is....my '04 Maxx LS averages 24-26 mpg in mixed driving.

I get around 27 on the highway and low 20's in town...with 75 percent highway and 25 percent town I get about 24 mpg...I was a little disapointed. I'm hoping once the weather warms up here in WI my gas mileage will improve.

I wonder when the cars are tested for fuel economy whether E10 ethanol blend is mandated. (we can't get other than that in NY and I know mileage would increase with straight gas). While it would be nice to be less dependent on foreign oil the more I read about E10 ethanol blend the less I like it (gas separating into layers if allowed to sit too long...more of a problem with lawn mowers, etc that sit a while and especially a problem in boats, being near water, or anything not using fuel injection). Also reading that the ethanol is added later in the manufacture and there is room for fraud/error so everyone's mileage could vary if say the 10% is exceeded -which is highly illegal as engines can be damaged).

So everyone's reporting high 20s....
Why am I only averaging 20 on the in dash computer?
I don't drive heavy and the tires are inflated properly.
Just bought my 07 maxx in October and still haven't seen these mid 20 figures.
Any idea why my efficiency would be so low?
