Do large diesel SUVs still create the Euro 6d standard?

Hello, since there are not yet large diesel SUVs of the format of a BMW X5 / Audi Q7 / Porsche Cayenne with Euro 6d (Temp) standard, the question arises whether these will ever create the standard (without tricks) at all? The question will not be quite unjustified, because at Euro 6d is measured according to RDE standard (i.e. under real consumption), and these heavy vehicles consume here now even more fuel than before under laboratory conditions. Perhaps it will be a solution where large quantities of Adblue are consumed, o.e….. The problem with these vehicles is that as a diesel driver the fast driving (approx. 180 km/h) on the motorway is used, but this would cause enormous extra costs when switching to a petrol engine, because gasolineers start drinking when driving fast. What is your opinion on this?
