We purchased this vehicle may 15 and have driven it 850 miles. We drive from 7000 feet elevation down to 4500 feet elevation , some town driving and back home. We drive at 55 mph.
Our mpg is an outstanding 71.2 mpg.
I expected about 55 but this is just amazing.
FYI.
Do not rely 100% on the cars computer as these can often be inacurate. On your dash, it's showing 33 ish MPG for me? Did you add a fuel up incorrectly?
Are you driving the standard hybrid or plug in? Starting every day with a fully charged battery instead of using engine and regen brakes would make a huge difference.
I'm just approaching 5k miles in my Premium SE and the one thing that staggers me about this car is that the engine will cut out at over 70mph and the car will run on battery power.
