I drove a Volt for two years, and I had the VoltDC app that showed me my EV to gas mile ratio, and let me compare to other VoltDC users. I had the gassiest Volt in Louisiana.
Why was this?
For road trips that didn't demand some specific quality in the car, I chose the car with the best economy and infotainment. The Volt would get ~40MPG in steady interstate driving, with XM, MP3, or while hooked up to a phone. With OnStar navigation going too, the 4Runner was left behind.
My commute to work each day is about 1.5 miles each way on mostly 25MPH roads, with no traffic lights. Shopping is mostly within 3 miles. My wife works 2.5 miles away. Eve with me going home for lunch, a GEM could do the drive year round. Aside from Enterprise rental cars moving where they can only be accessed via a 45MPH road last year, if I was forced, I could probably do quite well with a 2-door GEM and an Enterprise rental discount card. Heck, the new location is only a few hundred feet down that road.
But, a GEM is a death trap. And, as good as my town is for having a 35MPH speed limit on most main roads, and having most main roads backed by a 25MPH grid system, I can't get everywhere when faster roads are lava. I can't go to the vet's office, the hospital, or my doctor's office. I can go to the mall, Target and Albertsons, but not Winn Dixie and Wal-Mart.
So, I need to have my whole town available. The gas vehicle, my wife's 4Runner, would have to be on road trip duty, and if only one of us was headed out of town, the remaining vehicle needs to be able to access everything in town.
A Leaf or i-MiEV would certainly open up my entire little town. Driven carefully, my nearest major cities, Baton Rouge and New Orleans, would become accessible. A CHAdeMO public station in either city would turn these places into carefree drives that could be taken on the interstate. With only 220V level 2 stations, it's an exercise in dressing for the weather with modest hypermiling. With about 10KWh usable battery in the Volt, I've tried making the trip for the fun of it. I rolled into the Nissan dealership with about 5 miles remaining. An attempt at making a round trip in the Volt using only electricity showed me that I just don't have the patience to hang around a public charging station. I had breakfast in Whole Foods, walked around the Books A Million, bought a book and read a good chunk of it over coffee, briefly had a security guard in a golf cart follow me as I had the audacity to walk through the yuppie parking lot, and finally gave up and drove home, running out of EV and switching to gas on the outskirts of my town.
Under the same conditions, a Leaf would have about 2.5 times the usable battery, and the right spec would give me a 220v charger that is twice as fast as the Volt. That would turn the next major town into a viable destination if the interstate was avoided.
I think that's the point where I could say that I'd be able to get by.
I think I could get by with a Leaf equipped with a 6.6kw charger. I probably wouldn't even need any more than the 110v EVSE, except that Nissan recommends that 110v be used only for occasional charging in the 2013-up manual.
But, what about getting the range that would make me want to own a BEV?
Well, that means one more drive has to be supported. Visiting family.
My mother and sister live half way across the state. I might be able to plug in 110v there for four hours or so when I visit. Round trip is 245 miles. The interstate speeds for most of the trip mean my only real choice is an upgraded Tesla Roadster 3.0. The Model S would still force me to hypermile. A supercharger is not on my route, nor is one planned. If I change my route, I could possibly hit the Supercharger coming in in 2015 or so. If that happens, a Model S 85 could make the run, and I'd be ready to kick the gas habit.
Or, I could just drive a Volt, ELR, i3 with range extender, i8, Panamera Plug-in, Fusion Energi, C-Maxx Energi, or some other car that gives me a meaningful EV range, but backs it up with a gas generator. Louisiana has no public charging infrastructure to speak of, so I need gas as a backup.
Honestly, I'm hoping the i8 depreciates. If values act like an SL600 AMG, then I'm good. If values act like a Z8, I'll never own one, and that will be a shame.
