Prime mileage and temperature

Since I got my Prime in December, I have been more than pleased with the mileage I have been getting, expecting a boost when the weather gets warm. My daily commute of a little over 35 miles each way is 25 miles of interstate sandwiched by 5-6 miles of local roads at either end. In the morning, I use EV on the local road, switch over to HV on the highway, then back to EV on the local roads closer to the office. In the afternoon, I run on auto EV from work until I have about 5 miles of battery left, then switch to HV, saving the last of the battery for the local roads before I get home (this is also the heaviest traffic area). Using this strategy, I have been averaging about 71 mpg each day on my commute, a little more or a little less depending on variables in weather and traffic. (high temps ranging from 27 to 45 degrees).

Today, it was freakishly warm for a Jersey January day, with a high of 68 degrees. What a difference that made. First off, there was a notable difference in performance of the engine, quicker acceleration and a quieter ride. On the way in, my mileage was 86 mpg, and had much more battery power left when I got to work. But the way home was the sweet spot, when I pulled into the driveway, the trip odometer read 119 mpg. If that's what I have to look forward to in the spring, it will be one sweet ride!
