Strange. Mine is about 480 miles per fuel tank maybe 500. Try to brake with engine before get to the lights when it is red. I change gear shift for mode 3 from D to do it. It safes a lot of fuel because injectors stop providing gasoline to combustion chamber till 1800 rpm.
not really sure how to respond to this... but DOWN shifting to slow down the car is going to put more wear on the torque converter and engine then it is worth. Plus, you are revving the motor to higher RPM's which use more fuel (engine can be at any speed without burning fuel). But since you are in ECO mode while decelerating you are using half as much fuel but since it is a higher RPM then while decelerating while in D you are technically using more fuel. Plus, this car seems to upshift on its own while coming to a stop while braking.
I wouldnt do this. you are better off leaving the car in D and taking your foot off the gas long before you need to stop then hit your brakes....
It tiilts me SOOOO hard people stepping on their brakes a block away from where they need to stop. Riding / feathering the brakes for that long is goin to wear them more than hitting them closer to the stop.
Maying your putting the feather action on the throttle all the time to see this kind of mileage and highway mileage at 55MPH.
My last tank was mainly 80-85MPH freeway and I saw about 22MPG
Tank before that was mainly 70-80MPH freeway and was almost 24MPG
Next long drive (casino's HA!) Ill TRY to do a constant 65 and see what the MPG looks like.
