if you like the volt, realize the volt will likely be a key part of GM’s platform in 5 years. the Cadillac ELR is using the VOLTEC drive train, in 5 years, i suspect
GM will have extended that into escalades, Sierra’s, etc..
Toyota is continuing to grow the Hybrid Synergy drive. I suspect in 5 years
all of Toyota’s platforms will have a hybrid option and many of them will have
a Plug in option with a range of 20 Miles electric.
as for the Tesla, not every car has to use the Tesla battery, so much as they have to have a removable pack that’s mechanically compatible to Tesla.
Or what’s going to happen is you will see little small range extension trailers
for EV’s that have to take the occasional long road trip. When the EV-1 came out the engineers rigged little generators on 2 wheel carts so they could ferry to the test track. I suspect as EV’s get bigger, Level 3 charging, battery swap and the towed trailer will all add to the choice matrix.
I’m not sure why you are so down on Battery, but it would seem you are a better client for a Volt, a C-Max Energi or any of the EREV hybrids, so why not get one of those?
