Is a self charging hybrid really much lighter than a PHEV? unless I’m mistaken, the only difference is the (lack of) charge port and maybe an electric module or two. self charging hybrids are lighter probably because they have much smaller batteries, which means worse economy.
The self charging hybrid, will be far more efficient, if your can’t charge a PHEV at home. Also, how you going to charge the much bigger battery in the PHEV to its full potential, if your not going to charge it? There’s a reason self charging hybrids have abattery under 2kWh.
