I have a 3LT with the 3.9 engine that has approximately 1400 miles on it. So far, I have been doing only "suburban" driving on relatively busy streets and low speed highways while on my way to and from work. I've been getting anywhere between 17.5 and 18.5 MPG, depending on ambient temperature and how aggressively I drive the car. That is a little disappointing, since my 2001 Regal, with 57K consistently gets 19-20 under the same circumstances. I have to admit that the acceleration is better with my Impala, but, . . with all the technology improvements made in the last five years, I should be getting at least the same efficiency with the Impala. I'm really looking forward to doing a couple of trips to see if the Chevy can match the 29 MPG that I get with the Buick.

The Regal with 3800 V6 has a lot less Horse Power (40 HP less). Besides, the new 06 Impala is probably heavier since it has more safety hardwares. HP and mass negate any gain on new technology. If Chevy offers 6 speed AT then may be they can offset the loss in MPG (10% better typically). DoD (Displacement on Demand or Cylinder Cutoff) may save another 10%.
In addition, the 3800 engine is legendary for HWY mileage (30 MPG on large vehicles) since it has benefited greatly from decades of continuous improvement.It may take GM some more years to do the same thing on the 3.9 V6.

I have about 4200km (about 2600 miles) on my '06 LTZ. Best tank has been 10.61 l/100km (22.16 USmpg). Worst has been 13.55 l/100km (17.35 USmpg). Average is 12.17 l/100km (19.29 USmpg).
Mileage has been getting better as the engine gets broken in. All of my driving is mixed city/highway, with average speed per tank of around 55kmh.
I am definitely a heavy-footed driver, particularly with the great acceleration of the 3.9 in the LTZ. It's so much fun to put it to the floor and take off. It will be interesting to see what the mileage is like when I do a cruise-controlled trip down the 401. So far any trips on the 401 have been fun dashes into Toronto with lots of to-the-floor acceleration.

Being the "gear head" that I am, I'm well aware of the "advertised" horsepower of the Chevy when comparing to the Regal. The Regal I have is a fully optioned car and weight is nearly the same, but the aerodynamics are not as good as the Chevy. With the experience GM obtained from what was considered one of the finest six cylinder engines ever built, that you would expect the 3.9 to perform at least as well. If you drive both cars similarly, over the same exact course, you'd expect the Chevy to deliver similar mileage. For example, the 99 Z28, 6-speed that I traded for the Impala produced almost 300 horsepower at the rear wheels, weighs only about 150 less than the Impala and got the same mileage (or better) over the same course, same driving conditions.
There's no doubt that a 6-speed automatic and DOD (DOD is rumored to be installed as standard equipment on the '07's) would significantly improve mileage. Imagine how much better the 3800 Buick would be with those same improvements! Don't get me wrong. My Impala is a decent car and I knew going into the deal that it wouldn't get the mileage that my Buick does. My point is that with all the performance and mileage that some GM cars develop, you'd think the 3.9 would be more efficient, just on the motor alone.

SS showing off on I75 today. Changing lanes to pass people and I heard this loud muffler sound like something from the early 70s on a big motor and it was an SS-black passing at 80 or above. He had a cops emblem on his license plate so he can speed and nto worry.

You're right, my mistake. When I was posting I couldn't remember if it was in the high 140's or 160's so I went with the smaller speed.
You're also right in saying that it is difficult to test top speed. There's nowhere around my area where I can (or desire to) safely go over 140 mph....

offerred in the Impala Yet?
Also, when you change gears, what on the Dash tells you what gear you are in. I saw this on a last gen Lexus GS and it looked cool. It looked like a grear follower with a light on what gear you are in, not just a few lights that show up when you change.

My apologies for not responding sooner...for various reasons I haven't visited this forum in several weeks.
[quote="zjim"]Were the HuskyLiners for the '06 Impala a custom "drop-in", or did you have to trim them to fit? I hate to pay that kind of money for a "universal fit" floor mat. No offense, I know you said that they were a perfect fit, but I'm very fussy about this type of accessory. Do they have the "step plate" texture to them? I'm most concerned about covering the drivers side raised portion where your left foot rests while driving. Also, do they protect the raised floor just in front of the seat?[/quote]
No offense taken. They're a custom "drop-in" specifically for the '06 Impala and GXP (twins, at least in the floor areas), and they do have the "step plate" texture. They do cover where your left foot rests while driving. However, they do NOT cover the raised floor just in front of the seat, nor the raised floor right next to the door/entry. So, you still run the risk of stainage at those spots. But, it's still an excellent compromise that *mostly* does the job.

What kind of issues have you had that led you to file a complaint with the BBB? I had the clicking behind the instument panel and have heard of others having problems with the heated sets and radio, but that's harldy cause to file a complaint with the BBB.
