It's only a range estimate based on driving history, not a indication of battery capacity. If your driving pattern is different, the range estimate will adjust over time.I am a new owner, only three weeks, is there any reason why my 2014 V would only be charging to 28 miles on a full charge?
38's the MINIMUM according to some documentation. Dealers seem to look at 32-35 as correct. First stop after any dealer trip is usually to Kwik-Trip to air up and give myself indigestion with a turbo dog to go along with the sour stomach from the dealer coffee.Also don't forget to properly inflate your tires. 38 psi is what is called for - dealers don't seem to agree.
And if you want a better idea of how much range you are _actually_ getting and how efficient it is, you can look at the Energy Info display.It's only a range estimate based on driving history, not a indication of battery capacity. If your driving pattern is different, the range estimate will adjust over time.
I believe you answered your own question in this paragraph (75% @ highway speed). Why so much use of Mountain Mode? I thought Texas was pretty flat.I drive in L all the time, and in mountain mode unless I am running purely on battery. I only use Normal in slower speed areas. Approximately 75% of my miles are highway speed ( 10% of that is on the Interstate, the balance of that is on US Highway or paved county roads). With regen and midday charging I am getting 45 to 50 miles pure electric between full 110V charges at night.
Our Wheels & Tires sub-form has an FAQ on runflats for the Volt. http://gm-volt.com/forum/showthread.php?105593-Chevy-Volt-Wheels-amp-Tires-FAQsI am curious if there are "run-flat" tires available for the Volt. (I end up on gravel or dirt roads maybe 10% of the time)
