It all depends on what types of journeys are your normal daily use?
the thing about PHEVs is the ability to carry out small journeys on battery only and longer ones on petrol/battery. Don’t forget the Kuga can charge your battery from the petrol engine also, plus some regen braking, so if you don’t have a home wall box and cheap ev tariff, you can charge at public chargers as top ups. The use of battery power is to not run them down to 0, but keep charging
