Re: Well I wonder what happens now?

Now that diesel is essentially a busted flush unless you piss on it, will they go back and look at lean burn petrol?

Lean burn is what got VW into this mess. Lean burn engines -- be they petrol or diesel -- run at higher temperatures than engines burning a richer mixture, and so suffer from more oxidation of atmospheric nitrogen, giving rise to NOx in the emissions.

If the problem of NOx could be overcome there would be no problem with diesel.
