EREVs are under appreciated.
A tesla model Y consumes 320 Wh/mile travelling at 75 MPH speed. So it would consume 24,000 Wh per hours (320 Wh/mile ×75 miles). So they need an average power of 24 kW to travel in highway speed. 24 kW=32 HP. An EREV with 32 HP engine and 30 kWh can provide enough power for acceleration and hill climbing. (A 30 kWh battery can give a power of 120 kW or 160 HP, in addition to 32 HP from the engine)
A 30 kWh battery can 120 miles of electric only range.
Also EREV would be much less mechanically complex compared to an ICE or PHEV car.
EREVs would allow people living in countries with less improved charging infrastructure to take long road trips with worries.
Another benefit of EREVs is winter driving. You can heat both the cabin and battery using the waste heat from the engine.
