No I agree......but there are reports of a few vehicles far earlier than the supposed qualifying years (so 2003 - 2005 petrol and 2015/16 diesel) qualifying for exemption with no modifications.I wouldn’t think any C4’s would be ULEZ exempt
Being as the 'septics' were way ahead on clean emissions it perhaps follows that 90's yanks could in co/nox figures be within TFL's limits. Problems going to be finding someone to either measure the levels on a specific vehicle in a way that TFL will accept and/or quality OEM quoted figures. It's being done for motorcycles - so why no cars?
The big problem is TFL working from vehicle registration information and not OEM published figures. European OEM's will send (sometimes for a fee) conformity information......not sure about North American OEM's though.
