Re: All this just to avoid using ad-blu
I shall tell you why.
It is generally perceived by manufacturers that the extra cost of installing an adblue system on 'cheap' and 'low margin' cars is not feasable, because it would
a. drive up the price of a car. On a 100K luxury boat the extra money for the system is negligable, en a 10K ecobox it's a substantial procentual increase and
b. there's the extra maintenance and running cost, which can not be easily justified if you are competing with manufacturers that sclaim they can do without (but are in fact cheating).
No business case is very clear for the very expensive and very cheap cars, but there is a very large middle ground (Golf, Astra, 1 series, A and B class) that is fiercely competitive and where a buck is a buck.
Buyers DO vote with their wallets, unfortunately.
