md13ffhguy Report post Posted April 4, 2015 Took a long trip yesterday from central MD to southwest VA and back - approximately 300 miles each way. We took my wife's 2014 and it was 99% highway driving at highway speeds; not the normal stop-and-go commute I usually drive in my car. The trip out was a bit tedious, as it rained for a good part of the time, and we had three adults in the car, so I figured I would be at a disadvantage, as opposed to my normal commute numbers. Still, I was not entirely disappointed with 43.7 MPG, considering there was a lot of driving at 60-70 MPH. The return trip was another story, as I was able to employ the strategy of forcing a near-full charge to the HVB and keeping the ICE running at maximum efficiency. At one point, I settled in behind an 18-wheeler (not drafting, mind you) who escorted me for about 150 miles. His pace was perfect for this strategy - slowing slightly as we climbed and holding steady at 65-75 on level/downhill sections. I was amazed during one particular stretch as my instantaneous MPG never dropped below about 55 and was actually 60+ for several miles - all with the ICE running! Calculated MPG for our return trip was 52.1! :) 4 keybman, acdii, corncobs and 1 other reacted to this Quote Share this post Link to post Share on other sites
md13ffhguy Report post Posted April 4, 2015 What I find most fascinating about this trip is my percentage of EV miles. Normally, on my regular commute, I average about 50% or even slightly more. For this highway trip, I was able to achieve 47 MPG while only running in EV 30% of the total miles. When I first became an FFH driver some 18 months ago, this concept was completely counter-intuitive to my thinking! I figured the only way to reap the benefits of this hybrid was to maximize EV usage - which, obviously, is not always true! 3 acdii, hybridbear and corncobs reacted to this Quote Share this post Link to post Share on other sites
