The 3.5L probably will do 32-33, and I'm willing to bet some 3.5 owners will chime in and back me up on that one.
My Sister owns an 06 3.5L Impala. I have driven it a lot. It is a GREAT car. MPG is OUTFREAKINGSTANDING! I would not even dream of a new Malibu if an Impala was an option. The new Malibu is like a sardine can inside IMO( I am 6'3 and 300lbs )but the Impala has all the room you could ask for. Very comfortable ride and it has been very dependable. She did have some issues with the radio right at 1st( needed 3 replacements to fix it )plus the engine was replaced at around 7K under warranty because of a mfg defect( but the new engine has been 100% fine ). Other than that not a thing but oil changes.
Note - The engine issue was there from day 1. Had a slight odd noise I couldn't ID and over time it got worse. Even a GM tech that came down couldn't figure out what it was? Got to the point they just put a brand new engine in( not short block - long block ). GM was actually really good about it all. Got her a nice rental for the entire time her car was down and threw in a full 100K extended warranty free for the hassle. Can't ask for more. This is not the norm for the 3.5L. Excellent motor.
The EPA MPG ratings of 18/29 are vastly under rated as long as you are not a serious lead foot. Actually, last fall I drove the car to Virginia, to PA, and then back home here to NH on vacation. 3 full size adults and a bunch of luggage and other "stuff". Did the driving late at night when traffic was light doing 70 MPH in CC. 34 MPG average for the all highway portions of the trip. We saw 31 MPG total average over the 1700 miles of highway and city. Normal driving in the car is around 22-23 City and 30-32 Highway.
IMO it is a no brainer. The Impala is the ONLY chocie of the two.
If I was in the market for a car the Impala would be the 1st and only choice for me.
