In terms of respiratory disease causing NOx and carcinogenic particulate emissions,yes petrol is relatively clean compared to diesel. Diesel was incentivisised because of the first issue, but is now considered a serious public health issue in cities because of the second.

ABC101 wrote: » It was a rhetorical question I asked. Only some vehicles / models have adblue. Adblu is a Urea based compound which is stored in a tank, and metered into the exhaust system to reduce NOx. Other posters on boards have mentioned that on the adblu tank being empty the car will complete it's journey home, but will not start unless the adblu tank is topped up. Hence you cannot cheat the emissions requirement. It does not sound like a simple retrofit, more like something which is developed as part of a new design. I would imagine retrofitting a adblu system would not be easy, ECU upgrades, tank installations, filling caps, level sensors, injection pump and of course a exhaust pipe modification so that the urea can be pumped into the exhaust when the engine is operating. Installing all this in a existing older car would not be a small undertaking, and we would have heard a lot about it by now if it was becoming mandatory. Perhaps adblu will become mandatory in all FUTURE vehicle sales as part of Euro 7 regulations? But retrofitting older diesels would never happen in my opinion. Renault have publicly admitted that they are thinking of phasing out diesels in the A + B car segments, the cost of getting a emission compliant engine into a car of this class exceeds the sale price of the car, the return does not match the effort. The future appears to be EV?
