Other posters have good advise. My mpg goes up during the week when I commute - 70 miles round trip. Stop and go traffic doesn't hurt too much. I often take an hour to do the 35 miles, and sometimes over 2 hours. Park out of the sun. A/C takes a hit on the mpg if it has to cool off a sun baked car. A/C usage otherwise is only a 2 or 3 mpg hit if you use ECO and recir.

Avoid slow starts. Accelerate normally, and a few mph faster than you want to go. Then back off and feather the gas until you can maintain your speed. I often see the instant mpg at 55 to 60mpg doing this. On level or down hill grades, slow starts on battery only are ok in stop and go traffic. Slow uphill, EV starts drains the battery quickly and doesn't help your mpg.

I get about 42mpg at 70, 44mpg at 65, and 47mpg at 60. I tried keeping my speed close to 55mph for a few days on a new tank and racked up 51mpg (tank avg reading) over 180 miles.

Avoid 40 to 50mph unless coasting or slowing down gently. The TCH mileage seems poor between 40 and 45mph.

Drive with the load. By this I mean let your speed drop 5 mph or so as you crest a hill, and gain 5 mph or so as you hit the bottom of a hill. Let your momentum work for you.

Look ahead - avoid braking hard - or stopping completely in stop and go traffic. Be safe and stop if you need too! Anticipate traffic slowing and coast/run on EV when possible.

Hint: If you are going between 35 and 40mph, the TCH will almost always immediately drop into EV mode if you take your foot of the gas for a few seconds. If you know you will be coasting or going under 35mph for a while, speed up to 35mph to "ask" for EV mode before coasting. Otherwise you might only see 35mpg or so when going 15 to 20 mph.

I drive the last 1 1/2 miles home on EV. I accelerate to 43 mph, coasting down to 42mph, dropping into EV and gradually slow to 35mph and maintaining it. It is a very slight uphill climb, but by slowly loosing speed over the distance, I only drop the battery 1 bar doing so.

Hope you find this helpful!
