Personally, I don't like the hybrid concept. When I must rent a car and they offer me one, I refuse (if I have the choice), unless they guarantee its battery was plugged and is fully charged.
If it’s not, they showed higher consumption than the equivalent ICE model without the hybrid jazz. They seem nice when you arrive to a heavy traffic area and they move silently with the ICE off, but before that, you had the ICE precisely consuming more to charge the battery! You feel you’re not consuming in the traffic jam, but you consumed more earlier to have the battery charged! And as the efficiency is never 100%, the global balance is not good compared to the same car with just the ICE.
Last week I got again a hybrid (I had no choice). A BMW X2 25e plug-in hybrid. The battery was obviously not fully charged, so as soon as I left the airport and before taking the motorway, the 3-cylinders ICE was in charge of the task… From Barcelona to Tarragona, it made an average fuel consumption of 8,7 l/100km = 32,47 miles per gallon (UK). It claims to have 220 hp, but I could only feel a little bit of power when doing a proper kick down and have both the electric motor and the ICE working together. Definitely not my like.
An equivalent in power “only ICE” vehicle with similar power will consume less. And if it’s a diesel, probably half of that. Not worthy at all for my purposes.
I would have a fully electric car if the range was really way more than 500 km = 310 miles, and you have the complete certainty that you have chargers all the way. If you are travelling for pleasure and like to improvise taking this narrow road here or go for lunch to this other village there…. a full electric car is not the appropriate car neither… because you don’t have the range nor the number of chargers all over the place to improvise the routes. It may happen soon, but not yet. At least not here in Spain.
