Got a 2017 Volt last week and noticed that the terrain factor is constantly negative in the region of MINUS 2 but as low as MINUS 2.5, after considerable driving. I know the terrain factor is affected by weather (rain, snow, wind) but excluding these conditions and considering that the terrain is mostly flat why would the factor be this much in the negative territory? Checked the brakes but they are cool to the touch. The terrain factor should not be that bad as it affects the miles/Kw. Does anyone have a technical answer to this question? I tried to get answers from dealership and GM but nothing so far.
