There are lots of studies online about the CO2 equivalent of electric cars. The last one I saw suggested a pure electric car in the UK would produce effectively something like 60-70g/km I think. Not bad, but not out of the question for a n internal combustion car in the future.
One problem is that the official govt tests are completely useless for any car you plug in. That Volvo is probably pretty efficient in normal use because of the energy recovery, but the extra plug in capacity is really useful in certain situations. Iirc you can choose to save your full battery charge for later, which means that you could drive normally and efficiently until you get to a rush hour city, where you could do the whole city section on electric only power thus greatly improving efficiency and also local air quality.
Anyway.. I also like driving hybrids. Feels odd at first but after a while you go back to a normal car and marvel at all those stupid gear changes going on…
