Another road trip.

I did another road trip yesterday to Portland ME. Last week I reported on the battery range when you restrict battery use to regular roads (35MPH) and do all of the highway driving in Hold, i got 70 miles on the battery at that speed. In fact my guess-o-meter was up to 73 in the morning before I went to Portland. I got a free charge in Portland so I decided to use the battery on the highway at 72MPH. At highway speeds the battery range was awful, I only got 44 miles on the battery. The gas MPG for the remainder of the trip was great, 46MPG.

Cost to run on battery vs gas with electricity at 21.4 cents/KW, with a 90% charge efficiency thats 24 cents/KW and gas at $2.69 a gallon,

Battery @ 35MPH, 4.8 cents/mile
Battery @ 72MPH, 7.64 cents/mile
Gas @ 72MPH, 5.85 cents/mile

Thanks for sharing...Pretty standard across all vehicles, highway speeds of 72MPH will have worse MPGs than at 35MPH...Also for 2017 the EPA includes cycles that are more "real world" which includes higher speeds and more A/C use, all vehicles including 707HP ICE Hellcats are beating their EPA rating WHEN driven efficiently...With China's EPA cycles, they got 72 miles of range out of Velite 5...If you're the person who drives efficiently, not a huge value from the EPA's rating, should look into the NEDC's rating which is driven less aggressively...Remember for 2007 the MY07 Prius was advertising 60/51, then the EPA changed its rules for 2008 and the same vehicle got a rating of 48/45...
