Sounds like another "let's get these things off the market quick before we hit September and big fines". Seems to be happening a lot with many models recently.

For the sake of stirring some debate. These newdangled tests will basically tell us what we have known for years. Published emission figures are a joke. My question, will the engines be redesigned or will the CO2 and NOx figures go up? The former will (likely) mess with published performance figures, the latter will hit us in our pockets when we get into a higher emissions band. What will the manufactures do? And by extension, would you buy the first batch of cars / engines after the factory shut down?

Short term - there isn't a lot they can do other than tweak engines and/or accept higher figures, longer term I suspect we will see a change in design to cheat, sorry "get best for" these tests rather than the EU ones

Yes I also would be concerned about buying the first year or two of cars fitted with petrol particulate filters. The first cars with catalytic converters lost serious performance until they were optimised for real world driving. What would worry me is that the manufactures have been bumped into fitting particulate filters much earlier than they wanted to due to the VW emission scandal and September's real world testing. The consensus of thinking is that the particulate filters will cost quite a drop in engine performance and have very little real world testing so the early adopters will be guinea pigs
