Is the Mazda 6 ULEZ Compliant?
Based on 67,379 MOT tests, around 60% of Mazda 6s still on the road are likely to meet London's ULEZ standards, and about 22% are likely to be charged. For the remaining 18%, it depends on the exact Euro standard or month of registration.
The fuel mix matters: tested cars were 54% diesel, 46% petrol. Diesel 6s are generally compliant from 2016, while diesel cars from 2013 or earlier are likely to be charged. Every petrol 6 in the data (2002 onwards) is likely to be compliant.

How ULEZ rules apply to the 6
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 (54% of 6s tested): likely compliant from 2016; 2013 and earlier are likely to be charged.
- Petrol (46% of 6s tested): every year in our data is likely to comply.
6s from 2014 and 2015 sit on the boundary (18% of those tested): some were built to the required standard before it became compulsory. The Euro standard is sometimes on the V5C logbook, or Mazda can confirm it. Our ULEZ calculator can help.

Buying a used Mazda 6 for London: what the MOT data shows
The Mazda 6s in this data were first registered between 2002 and 2020. 2016 was the most common year, with 7,002 tests (10% of the total), and half were registered in 2014 or later.
6s from likely-compliant years passed their MOT first time 73% of the time, at an average of 80,403 miles. Older ones likely to be charged passed 62% of the time with 109,515 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 6s likely to comply are from 2016. 4,973 of them were tested; 2016 cars passed first time 78% of the time and averaged 70,157 miles. Check the Euro standard on the V5C before you buy one from around then.
On a budget, the oldest petrol 6s likely to comply are from 2006. 1,569 of them were tested; 2006 cars passed first time 53% of the time and averaged 103,803 miles. Check the Euro standard on the V5C before you buy one from around then.
Whichever year you choose, check the 6's weak spots. The most common MOT failures were lights and electrics: "not working" (5.4% of tests); brakes: "efficiency below requirements" (3.0%) and "less than 1.5 mm thick" (3.0%). The most frequent advisory was "tread depth below requirements of 1.6mm", on 16.7% of tests.
Overall, 70% of 6s passed first time, roughly in line with the 71% average for all cars, and they had covered 88,254 miles on average, more than the 73,145-mile average.
