PHEV are a fascinating piece of interim technology. My i8 lives to be fully charged - so 30+ miles electric range in a 1500kgs car.
BMW dealers *never* return a car fully charged, about which I chide them every time.
Charging the battery from the ICE is quite quick - about 1 mile range added for each mile driven: 50mph average speed stretches are welcomed, because the constant speed puts low loads on the ICE, but it still generates power for the battery. I almost welcome 10-15 miles of average speed roadworks!
During lockdowns, using the i8 for local journeys only, my lifetime average consumption was over 54mpg. Now that we're back into long-range journeys, and after a long road trip with somme spirited driving, it's down to 49mpg. Some of that drop was down to using 95 petrol rather than 97 or 99, because protesters were disrupting the supply chain: 95 gives about 10% poorer fuel consumption.
On that long trip I only twice was able to charge where I stopped for a break, or overnight. And that's the *interim* bit - our infrastructure hasn't caught up with charging demand.
