What is the problem with plug-in hybrids?
Needs consistent charging When the battery is depleted, PHEVs can consume more petrol than an equivalent ICE car, reducing (or even eliminating) their advantage. To realise the benefits of a plug-in hybrid, owners need to charge their battery and drive it like an EV wherever possible. Charging the battery of your plug-in hybrid vehicle is highly recommended to maximize efficiency and power. Without charging, all-electric driving will be limited, and power reserves for the eBoost function will be much lower. For optimized efficiency, BMW recommends regular charging overnight.
