I picked up my car a couple days ago and it's even better than I expected. I've been doing my 17 mile (each way) commute and only using 15-20% battery even though I get up to highway speeds for big chunks of the commute (70-75mph). My morning commute I use about 15% because it's to a lower elevation. Then on the way back up on the way home I'm only using around 20%. I'd be happy with just making it to work and back with a bit to spare but I could probably commute for 2 full days before needing a charge if I charged to 100% and didn't do any side rides.
I've been just charging to 80% per some advice I've seen floating around. So after my commute home and back I'm at around 40-45% and I just charge back up to 80%. I'm estimating I'll save around $100-$120 per month by not having to buy gas. I still need to do the math to see it's cheaper to charge at home or at work. I'm guessing home is cheaper but I'll figure that out soon.
Love the car!!
