As some of you know we recently replaced a totaled "Early 2015" with a later build date 2015. Although it feels pretty identical, I did notice one HUGE difference with the new one. MPG!!

Now, we took a few trips with the "old" one and the best overall tank mileage we were able to get was 23.6mpg while running Shell 93 octane (about 260 miles or so). We just came back from a trip with the new one and my mind was blown. On the way there, running Shell 93 (10% Ethanol), we averaged 27.4 mpg, the speed average was 69.3mph while running the A/C. We were fully loaded (camping) with 3 people in the car. On the return home, I filled with BP 91 Octane (no Ethanol) and she clocked in at 28.6mpg on the way home, with an average speed of 71.5mph with the A/C on.

I couldn't be more thrilled!! I know this SUV is about 4000 lbs. and to get that close to 30mpg is outstanding!!

My question is this, does anyone know what changes were made? This definitely seems to be a software change. Maybe the updated software pulls more timing during highway speeds.

There were no changes that are known. Were your tires the same -- and identical tread depths? Was the route, weather, and wind identical in your comparison? There are many factors that affect MPG. Speed and wind seems to make the biggest difference in the vehicles I've owned.

Ok. I wasn't comparing just one trip with the old one. Our old one couldn't muster anything close to this one. Very odd actually...

Must have been something funky going on there - although you did not say which engine. I have a 2015 2.0 that I ordered in July and picked up in August 2014. I had the various recalls done, but I forget if any of them were software updates. I've only ever used what is sold as Regular with whatever ethanol was in it. My lifetime calculated average MPG is 24.17. I am mostly an around town driver. When I go back and look at specific vacation trips, one trip I got 27, 31, 30, 28 on consecutive tanks of highway driving only, and another of 27, 31, 31, 26. Mine was just two people, minimal luggage, AC and a fairly heavy foot!

Both were the 2.3.

These motors vary mileage dramatically based on wind and your right foot. I have seen 22 to ~26 on same trips . You can have Eco or boost but not both. BTW this is calculated mileage as computer is typically generous.
