My wife and I went to Portland Oregon yesterday shopping with our 2016 Volt. After the trip dash displayed, 47.5 electric miles (14.4 KWH used) 186.2 gas miles, (3.47 gal. gas used) 53.6 gas mpg, total trip miles 233.7.
Checked Voltstats.net, recorded there, 66.7 electric miles, and 167 miles on gas. Now the trip via Seaside Oregon to Portland went from home at sea level, climbed 1642 feet, over highway 26 down to 45 feet or so above sea level in Portland or so. The way back we changed are route, and went back via highway 30 which is along the Columbia River. Maybe its due to climbing a hill on gas then at the crest switching to electric and regen on the way down. I have noticed that the dash gauge records that as gas miles and not electric.
I'm just curious if anyone else has noticed this, quite a difference in data compared to voltstats.net and the dash display read out.
