I'm currently at ~900 miles and I am getting 20 MPG. RWD 2.0T(M). Mainly city driving since average speed is 24.9 MPH.
Bear in mind that if you've got the Driver Assistance Package (adaptive cruise control), the sensors take the place of the automatic air dams in the grill, negating whatever efficiency bonuses it would provide... I didn't realize that the sensors replaced the air dam before I bought the car... Not sure if I would have opted for that package had I known.
A lot of you guys and gals are getting much worse mileage than we got in our 3.0L cts.
A recent trip to amelia island netted us 27 mpg and trips to DC have netted us 28.3. These are averages for the entire trip. Cruise was set at x79-80 mph.
Even a few dips into the throttle and a couple of transmission kickdowns can ruin your average.
All around mileage of 2.0 is 17.1 over the last 800 miles. I'm at 1700 miles total.
It's amazing the effect of temperature on mileage. This weekend, I hit 1000 miles. Simultaneously, spring finally arrived in the south, with the temperature shooting 20-30 degrees, to the mid 70s. I got gas, had some traffic before getting on the highway, then after a 13 mile trip was getting 34.5 mpg, doing 60-70 and averaging 47 mph per the computer, which beats the EPA, and the car isn't really broken in yet. After a few days of city driving, my mileage has been 24 with an average speed of 30 mph, which is my benchmark average speed. In comparison, my CTS-V would get 16.5-17 mpg (manual transmission), and my '08 CTS 3.6 DI with a stick would get 20-21 mpg, both cars fully broken in, of course.
The last few days, it got cold again, and the mpg started decreasing again; then today, it warmed up again, and the mpg started to rise again. Hopefully, the same thing will happen for others, and the fleet mileage will improve dramatically. I for one am pleased that my car is now meeting or beating the EPA estimates, and I expect it will improve further as the car contimues to break in.
I had to make a trip from Philly to DC and back yesterday. On the way to DC I decided to test the highway mileage of my 2.0T (manual) so I set the cruise to 65 mph. Traffic was light and was pretty much always at this speed except for slowing for toll booths. I got 31.5 mpg for the trip. On the way back I drove more like I normally do (70-80 mph) and the traffic was heavier requiring more slow downs. I got 29.5 mph. In my daily stop and go commute I only get ~20 mpg.
Just realized my cadillac has DFCO, wasn't aware of that... will deff. be downshifting more :)
new to the forum and running my 2.5 ATS as my daily commuter, running 103 miles round trip....combined back roads, 40-45 MPH and interstate 65-75MPH with some short stop and go....only 650 miles on it so far, but averaging just under 29 MPG at the moment......in Northern VA and Western MD
my commute sucks... i'm averaging in between 17 and 19mpg :)
which is about the same as i was getting in my sti.
I'm at ~1800 miles and my stats are exactly the same as yours, 20 MPG, average speed 24.8 MPH. RWD 2.0T(M) as well.
Filled, reset and went on expressway.
Half hour commute, congested highway and clear city. Kept revs under 2k. I know not much fun, but was calming.
I was initially disappointed with my gas mileage (posted earlier in this thread). Now have almost 5,000 miles on the car. This last tank has been almost exclusively freeway driving. Taken it easy for almost all of the driving, other than entrance ramps which I always take spiritedly. Over 357 miles I've burned around 11 gallons of (premium) gas (according to OnStar app - likely it is closer to 12 gallons, but the app does not have a very high resolution, i.e., only displays full gallons). The DIC is reporting an average of 28.1 mpg. Not stellar, but I didn't buy this car for gas mileage. Bought it for fun and it is definitely fun. Long story short, I am happier with the fuel efficiency at this point than I was earlier.
