Is the Mercedes-Benz Cls ULEZ Compliant?

Based on 25,217 MOT tests, around 31% of Mercedes-Benz Clses still on the road are likely to meet London's ULEZ standards, and about 48% are likely to be charged. For the remaining 21%, it depends on the exact Euro standard or month of registration.

The fuel mix matters: tested cars were 88% diesel, 11% petrol. Diesel Clses are generally compliant from 2016, while diesel cars from 2013 or earlier are likely to be charged. Every petrol Cls in the data (2005 onwards) is likely to be compliant.

How ULEZ rules apply to the Cls

Cars that miss the standard pay £12.50 for each day they're driven in the zone. Petrol and petrol-hybrid cars need Euro 4 (most from 2006), while diesels need Euro 6 (most from September 2015).

Diesel (88% of Clses tested): likely compliant from 2016; 2013 and earlier are likely to be charged.
Petrol (11% of Clses tested): every year in our data is likely to comply.

Clses from 2014 and 2015 sit on the boundary (21% of those tested): some were built to the required standard before it became compulsory. The Euro standard is sometimes on the V5C logbook, or Mercedes-Benz can confirm it. Our ULEZ calculator can help.

Buying a used Mercedes-Benz Cls for London: what the MOT data shows

The Mercedes-Benz Clses in this data were first registered between 2005 and 2020. 2013 was the most common year, with 3,190 tests (13% of the total), and half were registered in 2013 or later.

Clses from likely-compliant years passed their MOT first time 80% of the time, at an average of 61,322 miles. Older ones likely to be charged passed 71% of the time with 105,821 miles on average, so a compliant car is usually the more reliable buy as well as the cheaper one to drive in London.

On a budget, the oldest diesel Clses likely to comply are from 2016. 2,074 of them were tested; 2016 cars passed first time 81% of the time and averaged 62,356 miles. Check the Euro standard on the V5C before you buy one from around then.

On a budget, the oldest petrol Clses likely to comply are from 2006. 476 of them were tested; 2006 cars passed first time 69% of the time and averaged 118,604 miles. Check the Euro standard on the V5C before you buy one from around then.

Whichever year you choose, check the Cls's weak spots. The most common MOT failures were tyres: "has ply or cords exposed" (3.2% of tests) and "tread depth below requirements of 1.6mm" (2.6%); suspension: "fractured or broken" (3.1%). The most frequent advisory was "tread depth below requirements of 1.6mm", on 17.0% of tests.

Overall, 75% of Clses passed first time, slightly above the 71% average for all cars, and they had covered 86,894 miles on average, more than the 73,145-mile average.
