'Dieselgate': Five carmakers go on trial over emissions cheat claims - BBC News

That's another one that annoys me. I think the fault, if there is one, lay with the people who wrote the test specifications, not the salesmen and not the manufacturers. One of my career jobs was in the design and development of new telecomms equipment, which had to pass stringent BABT tests. i.e. it mustn't pose any electrical threat to the user, it mustn't transmit data at too high a voltage so as to interfere with nearby equipment, and so on and so on. The products were built, and I took them to the BABT test houses for the approval certificates. The test house tested them to see if they were electrically safe, did they transmit frequencies that would interfere with other equipment, and so on. The test house did the tests in accordance with the test specifications as written by a board of government telecomms professionals.
So the cars were sent to the test houses to see if they met the specifications for emissions.
I expect the emissions tests specifications, written by some government people went something like: get the engine to running temperature. Put it on a rolling road, run it at 1,000rpm, then measure emissions. Run it at 2000 rpm, measure emissions . . . run it at 3,000, 4,000, 5,000 rpm - and so on.
The cars passed the emissions in accordance with the test specifications. It isn't the car manufacturers' faults that the test specifications weren't the same as driving up and down the high street and the motorway. If the specifications said 'no more than x% of CO2 at 2,000 rpm' and there indeed was not more than x% of CO2 at 2,000 rpm then it passed the specification. It's not the manufacturer's fault if the CO2 emissions at 2,500 rpm were higher. The specifications didn't care less what the emissions at 2500 rpm were. So the only reason for people crying into their exhausts and claiming compensation is to get money, not because they are tree hugging environmentalists. If they were environmentally that concerned they wouldn't have a car in the first place. And certainly not an electrical car: they would have investigated what environmental damage is done to the world to manufacture it in the first place - and even if they can reconcile that with their conscience then consider where their electricity comes from . . . . . and heaven forbid, how is this thing going to be disposed of at the end of its life?
