The French are actually fantastically competent at Diesels, same with FIAT (surprisingly). As for diesel in NA, I think its one large opportunity isIdk, the germans have the diesel market cornered, and really, only the luxury diesels sell, as VWs numbers are in the gutter while Audi does ok. I don't think it'd be a good idea to increase overall production cost of the entire lineup just to bring a diesel civic here that most likely, wouldn't sell well enough. I'm sure they'll offer one in Europe where small diesel engines are much much more popular, but here in the US people seem to only trust luxury car diesels and large truck diesels. Just my two cents.
IMO PHEV's are the solution. EV's don't make sense from a cost and usage standpoint, while ICE engines have been blacklisted by governments and society across the developed world (unfortunately, even though car pollution is a spec in global contamination, see commercial shipping). I know a guy with an MKZ Hybrid (not PHEV but regardless) who fill up once every three months...Diesel PHEV's should be the next step as gas prices start to rise, making more sense to diesels.
