I am 92% lifetime on EV versus CS (gas mode). 98% of those gas miles came from 3 longer distance trips in the last two years. Aside from those longer trips, I would be over 99% EV.
It is too bad that in this thread in particular there is a tendency to minimize the contribution of the Volt towards an EV future. 1.5 billion EV miles while not stunning is a great contribution towards the overall EV miles racked up world wide.
Don't forget that a lot of these first Volts were in fact GE fleet cars which for some reason NEVER ran on EV. Perhaps because GE reimbursed for gas but not electric? Some of these cars racked up close to 100k miles before being sold at auction. Second hand owners were far more likely to use these "rescues" in EV mode. But in the end, this is a Tesla board so we know how positive news (non-Tesla) is often received here.
