It Gets Better by phaetondriver

I just returned form my second road trip in a month and I watched my MPG get better and better on this last 2300 miler.
I now have 11300 miles on my XR and still lov'n every minute, well maybe not every...
I actually got 29.5-MPG for about 350 miles in Washington and Oregon. Sure it was flat but but I was averaging 80-MPH. Last month I went to Arizona and that was flat too, but I could only muster 26.4 for about 400 miles, average 78-MPH, before it got hilly.
My trip north showed 26.2 for ~1150 miles with plenty of stops and one overnight. I averaged 63-MPH for the 1150 miles. My trip south averages 68-MPH and 28.2-MPG.
The whole trip according to the computer showed 66-MPH and 26.8-MPG for 2300 miles.
I am so pleased it is finally coming around.
ONE THING THAT HAS HELPED THE MPG IS RUNNING THE LOW PROFILE GOODYEARS AT 40-PSI. This is 4 PSI below maximum which helped keep them cool and lower the rolling resistance (friction). The ride was a bit harsh, but it was worth it I think.
I also have over 6000 miles on this oil and the computer says I am at 30% remaining. That is killer. I am taking it in anyway for the oil/filter change next week.
I am going to replace a quart of oil with a quart of Dura Lube before the next trip to Arizona in September. We'll see if that helps the MPG like it has in my other cars.

Mostly city driving for me, and I average 20 MPG. One thing I noticed after driving for a few days was all of the tires were under-inflated ( Terrific TPS light came on ) . Could be a coincidence or could be something the average dealership misses.....so check your tire pressure.

Those little TPS valve stems are a godsend. I haven't had a flat or a nail in a tire in over 20 years. I get a new car and I get two nails in a week. Both fixable, because the TPS notified me by email (OnStar email report) that the pressure was low.
Low pressure can ruin a tire, and with these low profile tires you could damage a rim too.
NOTE: When you have your tires rotated, be sure the tire mechanic knows to relocate the valve stems. My mechanic didn't so when my tire got a nail the diag system said it was a front tire when it was the rear one.

Anyone here have any real-world mileage to share on the Aura Hybrid?

I have a 2007 AURA XE. It has 2,990 miles on it. It is averaging less than 16MPG. Worst tank was 13.7. Best tank was 16.7. The 16.7 tank had quite a bit of HWY mileage. So, I went to my dealer. They asked me to bring it in so they could check it out. The computer says the AURA is working just fine. So, they suggested I call Saturn to complain about my poor mileage. I did that and they had a regional manager call me. Here is the bottom line. Since the car checked out on the computer there is nothing they will do about it. I am convinced this car will continue to under perform on mileage. Right now if I were to go on a trip, I would get better performance out of my Trailblazer. I am a 30 year GM customer that is leaving the fold if Saturn/GM does not step up to the issue. Any advice or suggestions?

Are you figuring the MPG by hand, or relying on the car's readout/driver info center?

My 07 XR started out getting only 24/17 or so early on. Now I have over 12000 miles and I have seen over 30 MPG on a 350 mile run on level ground. I averaged over 27 MPG on a 2300 mile trip mixed but mostly interstate driving running 80 mph most of the time.
Your XE should get better than my XR but I think you need to give it at least 10000 miles to brake in the engine.
 
So before you throw in the towel, wait at least 10-12K miles then re-evaluate your XE

I am considering a XR and love everything about it except the disturbing reports on low gas mileage. You should NOT have to wait 10K miles to brake in the engine to get decent mileage. This def could be a "deal breaker" for me....

I notice that the posts regarding real world fuel economy show great variation and this is likely an indication of driver behavior and not variation in the Aura vehicles.
 
I recommend you rely on the EPA labels to get a relative (not absolute) sense of fuel economy. The EPA test cycle removes the variation in driver behavior and is a measure of the vehicle.
 
Personally, I think the Aura is a fun car and I find myself driving it hard -- and there are consequences with respect to fuel economy. With Aura you can achieve good gas mileage by driving conservatively, but you can also have fun when so desired.

I agree with you; my driving style is pretty conservative, and I've consistently achieved the "old" EPA numbers with my previous/current cars. So my gut feeling is that I should achieve better mileage than the "new" figures they've come out with.
 
To try to get a handle on what I'm apt to achieve based on the new numbers, I took my current average MPG and then adjusted the ratio of city/highway driving of the new numbers to deliver that number, and then use that combination to compare cars under the new system. Basically before on the old numbers my mileage equated to something like 80% city/20% highway, but using the new numbers now it's basically 50/50. Even though most of my driving is around town, much of that is on the Interstate that bisects our city, so technically I probably do more highway driving than I think I do, so 50/50 is more realistic.
