Is the Mazda CX-3 ULEZ Compliant?
Based on 25,466 MOT tests, around 98% of Mazda CX-3s still on the road are likely to meet London's ULEZ standards, and about 0% are likely to be charged. For the remaining 2%, it depends on the exact Euro standard or month of registration.
The fuel mix matters: tested cars were 88% petrol, 12% diesel. Every petrol CX-3 in the data (2015 onwards) is likely to be compliant. Every diesel CX-3 in the data (2015 onwards) is likely to be compliant.

How ULEZ rules apply to the CX-3
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).
- Petrol (88% of CX-3s tested): every year in our data is likely to comply.
- Diesel (12% of CX-3s tested): every year in our data is likely to comply.
CX-3s from 2015 sit on the boundary (2% 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 CX-3 for London: what the MOT data shows
The Mazda CX-3s in this data were first registered between 2015 and 2019. 2019 was the most common year, with 7,621 tests (30% of the total), and half were registered in 2018 or later.
Every CX-3 in the data is from a year likely to comply, so age and condition matter more than ULEZ when choosing one. The newest (2019) passed first time 91% of the time at 24,648 miles on average, and the oldest (2015) passed 82% at 54,599 miles.
On a budget, the oldest diesel CX-3s likely to comply are from 2016. 1,030 of them were tested; 2016 cars passed first time 81% of the time and averaged 48,665 miles. Check the Euro standard on the V5C before you buy one from around then.
Whichever year you choose, check the CX-3's weak spots. The most common MOT failures were visibility: "does not clear the windscreen effectively" (2.3% of tests); brakes: "less than 1.5 mm thick" (1.7%); tyres: "has a cut in excess of the requirements deep enough to reach the ply or cords" (1.5%). The most frequent advisory was "tread depth below requirements of 1.6mm", on 11.5% of tests.
Overall, 87% of CX-3s passed first time, well above the 71% average for all cars, and they had covered 36,796 miles on average, fewer than the 73,145-mile average.
