Lifetime (16K+ miles) average MPG: 24.6

I drive mostly highway so I'm disappointed with the lifetime average MPG. However, there's something about Florida roads and this powertrain that encourages my right foot to drive at Autobahn speeds, so it's not too bad. Ugh, but then I remember that my BMW X5 (6-cylinder) got around 22.6 MPG combined for a 7-seater.

If I drive within 10 MPH of the speed limit, I can get close to 29 MPG on highway trips, but that's no fun because I have to drive the vehicle like a Prius driver. I haven't bothered to check city driving MPG, but I bet it's not great. If I stretch it, I can get almost 350 miles to a tank.

As cheap as gas is right now (~$3.19/gallon premium), I'm not too impressed with this car's fuel economy especially compared with other cars I've owned. Despite those cars being naturally aspirated, heavier, and older, they got nearly the same fuel economy, +/- 2 MPG, with similar driving habits.

Still, fuel economy is not a major concern of mine.

About two weeks ago, I had a 2018 Toyota Camry as a rental in Denver, Colorado. I'm sure the altitude affected the performance so it did feel "slow" by QX30 at sea level standards. Driving around the elevation changes at Rocky Mountain National Park, highway, and some routine city driving, I was averaging 32 MPG. I was very impressed especially since I was by no means trying to drive in a frugal manner.

Needless to say, I think we're doomed to sub-25 MPG based on our driving habits and the performance this car offers.

What a coincidence, I too managed to get 29 MPG on a 240 mile trip a few days ago (95% highway). I utilized the Intelligent Cruise Control and kept my max speed at 80 MPH. Occasionally, I got bored and floored it to overtake other vehicles, but nearly all of the driving was driving at or around 80 MPH. I know that's plenty fast, but the highways in Florida are so silky smooth and straight, a contrast from the D.C. Metropolitan Area where I'm originally from.

I think that was because of the speed (75+) along with a headwind of probably 25 mph.

Still, I haven't been getting 30 ever. I do have an AWD, but I generally drive alone and use the cruise a lot. I don't have adaptive cruise, but I have the Premium with everything else.

My fuel economy average if I'm driving triple digit speeds (MPH) is 24-25, so that sounds about right. However, going up an down I-75, I can easily get 29 MPG with cruise control set to 80 MPH. I also have AWD.
