And in winter cold the battery gives you less power so your MPG drops.Read the spec details closer... this is NOT and electric vehicle... it is a plugin hybrid. They are in fact different.
If you think you will never need to stop into a gas station with the 2021 plug-in hybrid.. you are either never going to drive more then 30ish or so miles a day and always plugin overnight .... or you are deluding yourself.
AND... since it still has a gas engine component.. it will still require regular gas engine maintenance. Even if you literally never drive enough distance to fire up the gas engine.. it still needs to have the oil and other fluids changed periodically.
As for Teslas.. if you think they are zero maintenance ... you have been drinking too much Elon Musk flavored coolaid.
Depending on your driving pattern, you could be weeks before gassing up or have to settle for only 60 MPG. I have a friend who commutes in a PHEV and he only gets 87 MPG lifetime.
