London ULEZ charges

[5w155t0ny]

Work colleague of mine is going to London to see Ed Sheeran in concert (takes all types I suppose ) and we were chatting about the rail strikes and the best option for him to get there.
Out of curiosity, I checked my Dec '06 CLK 200K Cab and the wife's '14 SLK 250CDi and was somewhat surprised to see that my CLK (£330 odd road tax) is not liable for the ULEZ charge, but the wife's SLK (£165 road tax) is. Anyone know how they work this out as the emissions are higher on my CLK than the SLK, which sort of goes against all logic for pricing?
Or maybe that is the whole point of the exercise, because there is no logic emanating from the head office of the leader of the asylum, Mayor Khan(t)?

The CLK is petrol and the SLK is diesel - my 0.8ltr Smart isn't compliant, my 3.8ltr Porsche is...

Just remember it's about making money, not about the environment

and if you go in at 10 to midnight and leave at 10 past midnight they get you for going twice.

and if you park up for the weekend you have been driving the car each day.

It's strange how car emission's work out.

Actually, from what I read they have reduced the applicable hours for the Congestion Charge, but not the ULEZ.
Designed just to extract money whatever the circumstances.

I don't know enough about your car(s) but the key is whether the diesel is Euro 6 compliant. If it is, you can get confirmation from MB and get DVLA to update your V5. That should ensure you are not charged ULEZ (and in the other cities now introducing emissions charges)

If it is not Euro 6 I think you have to pay, sorry. I think the petrol has to Euro 4.

ULEZ is (rightly) all about NOx emissions.

Diesel engines of a given Euro compliance (up to Euro 6) produce more NOx than petrol so need to be a higher Euro compliance to meet the requirement.
Hence a Euro 4 petrol is compliant, a Euro 4 or 5 diesel is not as only Euro 6 diesels can get below the threshold.
