I was reading LRM earlier and in it is the article about the millionth Discovery and support vehicles (and a S1 for some of the distance) going on the big journey over to Beijing. I saw it was mentioned in the article that all vehicles were built to Russian spec (to eventually be sold out there), but more importantly they are all petrols (5.0 litre ones in fact!) because the Diesel Particulate Filters as req. in the UK/EU would basically go kaput when the engine would be run on not-fantastic quality fuels? Does this suggest that in the nearish future it'll become a lot more difficult for people to go travelling by overland unless they start outside the UK/EU, or build a vehicle on an old identity? Or use petrol even???
