By what I see in European trade publications, I'm guessing diesel will be eradicated from passenger cars within 10 years, if not faster. Manufacturers like PSA are scrambling to find gas engines as customers are changing - yup, they now have excess diesel engine production capacity.
I was driving an i8 for the week. Amazing what you can do with 3 cylinders and electrics
Yes, i'm in France and here, in big cities (like Paris, Nantes, Lyon, Bordeaux, Marseille, ...), diesel cars (bus and trucks later) will be banned in downtown from 2020/2025. At this moment, to have a 2000 diesel car or a 2025 diesel car it will be the same : not allowed in downtown !
But today, if we have a pollution alert, diesel cars are'nt allowed in downtown but only from 8am to 8pm !
Last year, diesel cars sold less than gas cars ! PSA, for exemple, could not cope with the demand for gas engine and had to import engines from his chinese factory ! At the same time, PSA (always for exemple but it's the same for all car manufacturers) can't sell his already produced diesel cars !
This "scourge" in France (and Europe) is due that the Frensh buy diesel cars with less than 100 hp for drive only less than 50 km a day in traffic jams for go to work. This clogs the particle filters and that causes 10000 death a year directly because of diesel particles !
PS : sorry for my english, do not hesitate to correct me
