I just filled up after a 425 mile trip (about 85% highway & 15% city). It took 14.95 gallons (about 28.4 mpg)

I just drove from Vail, CO to Indianapolis with the cruise set at 77/78 for most of the trip. I got 27.1 mpg.

Just got a 2010 CTS sedan with the 3.6 and AWD. First tank was 23.6 mpg in mixed driving (70% hwy-30% city) but with straight hwy the average is around 26-27 mpg. Over the exact same commute my '05 LeSabre with the 3.8 liter averaged about 27.5 mpg, so not too much worse for 100 additional HP and AWD!

In three additional tanks, the mileage continues to be between 22.8 and 23.8 mpg, calculated by hand for my CTS. I have not had a long highway trip yet. This is with using 87 octane, non-ethanol fuel only.

Is there anyone who has a CTS sedan or coupe with the new V6 that is suppose to be 20-30lbs lighter and pumping out 318 horses? I am wondering what is your current mileage and fuel economy.

I have noticed that wind will affect the mileage pretty significantly, but that speed does not seem to as much as my old car. Meaning, I get about the same 26-27 on the highway on a calm day at 60 or at 70 mph. At least so far.

Now a few more months into owning the '10 CTS AWD. Mileage on my commute is pretty steady at 22-23 mpg. I did notice that it went up about 1 mpg when I used non ethanol fuel (not premium, just 87 octane). I have had a few 100 mile trips, and the highway mileage has not been below 25 mpg.
