Can’t really understand the hype for plug in hybrids. At best, you can drive 30 minutes on the battery. If your car gets 30 mpg average your saving about 1/2 gallon of gas. In California, that amounts to about $2.50. Offset that with the higher cost of charging your plug in, 11 hours on a 110v connection, about 4 hours on a 240v connection. And if you don’t have a 240 line in your garage you have to pay an electrician to install one. So where’s the savings?
They aren't all that popular compared to BEVs and regular hybrids. California recorded ~380K BEV sales and ~64K PHEV sales last year.
