DTE is simply an estimate and highly inaccurate, till you get close to emptyI thought the same thing when looking at my fuel gauge. After I started it back up after my 250 mile trip back home the fuel gauge went down really fast and I was out of gas really quick.
Once you turn off the car, the trip reset to 0 and that is when they scam you. Your remaining miles stay the same. You are not going to get another 295 miles.
If you keep on driving, your average mileage will drop really fast.
The remaining estimate mile is pretty close to what you have left. You might squeeze out another 200 miles, but you will never get another 295 miles.
Edmund rated it at 477.9 maximum range on highway. How are you going to get 576? Manual or cruise control will not get you another 98 miles.
You have to chalk this one up as busted.
Edmund is using EPA HWY number of 27mpg (no actual testing)
EPA mpg estimates are based on a “driving loop” with variable speeds
When hypermiling/cruising, your speed is fixed as much as possible, there can also be favourable weather conditions and drafting when you can,,, so it will always exceed EPA numbers
EPA loops for reference
I believe, EPA has stopped using “highway” and publishes the “high speed” as the highway MPG now. (I could be wrong on this)
