As the proud owner of 2 vehicles with annoying faults, I would like to be ready to try to make a judgement about possible replacement(s).
Is there any source of sensible ball park figures for the various emissions of different types of engine, and likely real running costs?
In yesterdays Daily Mail, there was a readers letter stating that recent small petrol engines produce more NOx than diesels, and another letter saying that tyres are the major vehicular source of small particulates..
Looking around, I only seem to see guesswork and what looks like skewed data by agenda driven people.
What I'd ideally like to see is sensible measured info about exactly what is emitted by typical exhausts, and actual running costs, including the costs for home-charged electric vehicles.
I do realise that different driving conditions are relevant, but someone, somewhere must surely have done some real-world measurements
