Why Do PHEVs and EREVs Exist?

The existence of PHEV (Plug-in Hybrid Electric Vehicle) and EREV (Extended Range Electric Vehicle) stems from the fear, “what if I can’t charge the EV?” If electric vehicles were easily chargeable everywhere, these segments wouldn’t exist. So how do they perform in practice? As Etem pointed out, if you don’t charge a PHEV, you end up driving a 2.3-ton vehicle with a small gas engine. This configuration tends to be problem-free and offers reasonable repair costs. The most sensible PHEVs are from pioneers like Toyota and some Korean brands. Despite their older technology, Mitsubishi models stand out for their reliability and cost-effective repairs. Battery replacement can range from $6,000 to $12,000 depending on the brand and model.

Based on my own experience, I was enthusiastic about these technologies until two years ago. However, with the emergence of electric vehicles offering 700 km range using 800V architecture and a broader charging network, range anxiety has been resolved. Moreover, seeing the repair costs of new entrants in this segment over the past couple of years has been eye-opening. Therefore, considering the range improvements of electric vehicles and the costs associated with PHEVs, it appears unlikely that this segment will grow significantly. It's already shrinking in Europe. The purpose of EREVs becomes questionable when fully electric vehicles with 700 km range are available. In conclusion, for now, the best options remain a good internal combustion hybrid or a full electric vehicle.
