    If you are cruising 80 MPH on level ground, the hemi will not shift into 4 cylinder mode. Below 80, it will, but probably you will need to cruise at 70 or less to really get much deactivation.

    Well then on certain highways out west you will never used the DOD system.

    It all depends on how you drive. If you think that you have to speed along at 10 MPH over the posted speed limit, then your going to burn a lot of fuel. I fine that cruising at 70 MPH is fast enough to get 600 to 700 miles in a nice days driving. I can relax knowing that I will not be getting a speeding ticket any minute and the speeders whiz by in clumps every so often, but generally I am not in a clump of vehicles racing along. So at the end of the day, I am not worn out from all the stress.

    In some of the western states if you aren't doing 80 then you aren't going to be able to keep up with traffic.

    Their speed limits are 75 mph anyway.

    Surly you jest. The only thing you can find in Wyoming are cows, and not many of them. There is no traffic. Montana used to have no speed limit, but now they are 75. Even if you're cruising 80, some will pass you. At 70, I find that I am passing some (like trucks) while others pass me.

    The worst highway that I have been on for traffic was between Kansas City and St. Louis. The speed limit was not 75.

    MD has dense traffic so you don't see 80 very often. Then again, there is enough traffic that you can't use cruise control very often, either.

    I'm sure DoD would turn on and off frequently around here.

    I was thinking more of Arizona and New Mexico.

    You guys don't know what real traffic is! Try driving on an 8-lane divided highway which has a 55 mph speed limit yet the slowest right-hand lane is doing 60-65 and the fastest left-hand lane is doing 75-80+ and all this in bumper-to-bumper traffic :surprise:

    I got a sample of AZ's flat highways recently. Drove from Phoenix to Tucson on an arrow-straight highway, flat as a pancake, too.

    Speed limit was 65 IIRC but people would do 80 even with police on the shoulder. :surprise:

    Sounds like the Dan Ryan, Tri-State, or any freeway/tollway in and around the Chicago area!

    So I'm cruising along in DoD getting a 30 mpg readout from the driver info computer and I push ever so slightly on the throttle of an Impala and the car drops back to V8 configuration and my instantaneous mileage drops by 8% down to 27.7 mpg. 27.7 mpg be 'fair' for a 303 HP V8 from the GM guys who have no worthy innovations. I guess the Asian 303 HP V8's get 35-40 mpg because they are full of efficiency and other innovations of which American cars are starved of. 35-40 ss hwy mpg is available in what Asian V8 fullsize passenger car? Or is the 8% number GM media puts out set to avoid frivolous lawsuits? We are talking about a 35-40 mpg car geared for 5.3 second 0-60 times also.

    Do you actually have an Impala with the 5.3 engine? If so what kind of fuel consumption are you getting? My SRX can get 30 MPG's on level ground too, but this is usually momentary...

    On the government fuel economy website, one owner of an Impala with the 5.3 engine reports highway mileage of 20.5 MPG. Another reports 19.5, but some trips are more (23). Owners with V6s are getting around 25 MPG.

    I drove thru Chicago recently. Yes some people were speeding, but I found that the traffic was moving at about 60 MPH, not 80 MPH. I tried to stay out of the way of the speeders. I doubt that the speeders were really getting whereever they were going that much faster.

    My experience is that speeding along at 90 MPH does not really save that much time by the end of the day. This is because you will end up clogged in slower traffic a lot of the time. In Wyoming traffic clogs are less frequent, but most highways are two lane, so you will get behind a truck before long...

    So I'm cruising along in DoD getting a 30 mpg readout from the driver info computer

    According to the computer I got 69 mpg in a '98 Deville about ten minutes ago, so I think the computer is full of bantha poodoo.
  • sls002sls002 Posts: 2,788
    I can get an instant reading of 70 MPG going down hill. Even better though, driving my 98 Aurora into Death Valley from the west, the range for what was left in the fuel tank went up to 999 miles. The fuel tank only held 18 gallons full....

    What Impala does 0-60 in 5.3 seconds?

    The best time I can find is around 6.12 seconds.

    I just think you have a tendency to over exaggerate your numbers.

    Maybe he meant 0-60 yardsfeet?

    Car & Driver got 5.6 in their June 2006 test. They also averaged 16 MPG.
  • british_roverbritish_rover Posts: 8,476
    Yikes I hate to think how much they power braked the tranny to get that time.
  • ateixeiraateixeira Posts: 72,587
    OK, but 16 mpg is 16 mpg. That's lousy, period.

    People often brag about their record numbers, I'm sure you see 30mpg in the computer readout, but what do you get on a full tank? On average?

    C&D got 16mpg.
