Is this the beginning of the end of diesel cars? From what I understand, diesel cars registered before 1 September 2015 are producing dangerous levels of pollution and it is claimed up to 40,000 deaths a year are attributed to diesel cars. Mr Khan, London mayor, has said he is introducing an ultra low emission zone in 2019 that will put a charge of £12.50 a day on top of the congestion charge for any pre 2015 diesel car. Now, although I do drive in London I do avoid the congestion charge zone, so it will not directly affect me. However, what may effect me is that the zone may be expanded to the North Circ, which I use regularly. Also, any diesel pre 2015 is bound to be affected in terms of residual value, as I am sure other cities in the UK will follow the London example. So if I buy a new car now it will be unaffected, but will still give excellent mpg. However, will the whole "diesel is a killer" scenario taint all future diesel models regardless?
