The diesel controversy

[MuzzerParticipant @muzzer]

I think it's broadly the same here. Vehicles over 3.5t GVW don't require an operator's licence, so can usually be parked wherever you can park a car. Vehicles requiring an operator's licence need to be (normally) parked off the road at a nominated, suitable "operating centre". That's why you see Transits parked everywhere but hardly ever see a 7.5 tonner. It also explains why used Transit vans are often more expensive than their larger cousins.

Are the Germans bonkers?! Even if they could build a clean Diesel would anyone be stupid or naive enough to trust the Germans to make it. The Japanese maybe, or perhaps a US company based in California but surely not the Germans.

They obviously haven't read that France, the U.K, Norway and Holland all want to ban ICE cars. Spain, Mexico and India also have Diesel bans planned. Even some German cities want to limit Diesel use.

You can make diesels clean. Volvo did in the 1970's by fitting air filters to the exhaust system which removed all the soot particles.

Any problem can be solved, it all boils down to how much you want to pay.

New diesels are all fitted with a DPF (diesel particle filter). The problem is apparently the nano-particles which can clearly pass through the smallest of filter media available, for the flow rate envisaged. Oxides of nitrogen are not affected by any filter medium – they need a 'cat' in the line to convert them to nitrogen and oxygen. The oxides of nitrogen emissions were the ones that VW were caught out on.
