I am beginning to think that this is probably because no engine ever made
could pass the emissions standard on real life conditions of driving no
matter what you did. any standard that is not achievable is basically
pointless. What should be done is that a range of emissions under the
different conditions needs to be given and its up to the purchaser what they
decide to buy. and of course its up the regulators to decide on which list
they will support with their tax schemes.

Other cars have passed the same test so maybe they cheated too or maybe
they have better engineers.
