Off Topic:

Too late for that. AMA became Daytona aka France a long time ago (4 years?).

Sadly, MotoGP and WSBK (now owned by the same people) are making those series a fiasco as well.

Back to the mileage talk:

Re: Highway Mileage

Just arrived in Denver after a 440 mile trip at 80mph with my hemi. Got 19 mpg. Last week I did 500 miles in. Southern NM at 83-84 mph and got 16.5mph. Gonna try 70 mph next!

Problem is its almost 1200 mile drive each way from OP's residence. Most rental cars have base suspensions and suck on long trips. Big difference in ride quality between a STi and Altima and a GC. I used to make the run rom NOVA to Daytona Beach in under 9 hours and on really good days 8 hrs back in late 70's and early 80's. Speed limit back then was 55mph. 20yo and driving a 930 that the team owner wanted down in FLA always worked for me. Perfect car for the trip today a nice Jag XJR, a Vantage V12S or a CTS V.

Ditto. Depends a lot on tires and pressure too.

The best for me was almost 26. Usually I get 24 or so. I do have V6.

On the return trip of 440 miles from Denver I kept it about 74mph on cruise and got 20.2pmg.....not much improvement from going 80mph. But so much better than my 5.3L Avalanche that I used to drive!!

Very poor humor. I can easily maintain 20mph on moderately flat ground in the Hemi as long as I restrain my right foot and the urge to run over riced up s***boxes.

Uphill/downhill [as in western USA] is just over 18 even at speed limits you poor easterners can only dream of....

I'd avoid E85 unless it is a lot cheaper... alcohol mileages tend to be lower.

Re: Highway Mileage

I did a trip in the fall from Pa. to North Carolina, loaded to the max, for car camping. Cargo carrier on the hitch loaded. Highway mileage averaged just over 23 mpg with the V-6.

Re: Highway Mileage

Just got back from a run from Atlanta to Ft Lauderdale and back. Averaged 23.5 at 75 to 80 mph. By the way the most comfortable road trip I have ever taken. No driver fatigue what so ever!
Most comfortable Grand Cherokee ever!
