Hello, since we currently want to buy a car, we also deal very much with the topic of petrol vs. diesel. Since it becomes a used car, these used cars all fall into the range 2015 to 2018. At that time were relevant Euro 6b and 6c. In the narrow selection therefore a gasoline with direct injection and without OPF, i.e. a passat with 1.4 and without OPF. Later the passat got an OPF to meet Euro 6d. In the selection is also a diesel with DPF and SCR-K At, i.e. with AdBlue. So a later 2017er or earlier 2018er Passat, which was later certified according to 6d at the same time. But the vehicle just not yet and after-certifications will probably not exist. Since we also want to use the car for vacations, I have made some sense about the various driving bans in Europe. I noticed especially France (Crit Air). Among other things it is that the Euro 6 Diesel (even 6d) would get a badge 2. The Euro 6 B enziner (also 6b or 6c) without OPF would get a badge 1. It is known that Paris, but later also other cities and regions/regions (!?), plans to lock everything out under worse than 1. 0 would be eAuto. Then Euro 5 and Euro 6 petrolers would be allowed, but no more diesel – also not 6d diesel. My vehicle-technical question – that’s what this is about: Is a Euro6 diesel with DPF and with AdBlue not cleaner than a Euro6 direct injection gasoline OH NE OPF? Or why are Euro 6 diesel with DPF and SCR-Kat (AdBlue) locked out in France (soon) but not Euro 6 gasoline with direct injection without OPF? Or do I see this wrong, i.e. a gasoline with direct injection is nevertheless cleaner than a diesel with DPF and SCR-Kat? Would you like to answer the question in general, or if specific data are available: – VW 1.4 TSI with 150 hp without OPF (doesn’t have to be passat, the engine was installed in the complete model range) – VW 1.5 TS I with 150 hp with OPF – VW 2.0 TDI with DPF and SCR (was there also without SCR/AdBlue; in my case it is about a vehicle with SCR/AdBlue) How do the 3 motors compare in real operation with fine dust? (nitrogen oxides should not be a problem with all three, right?)
