Independent economy and emissions ratings from Green NCAP

Model tested: SKYACTIV-X 180 PETROL 4X2 MANUAL

Overall score: 2.5 stars
Date tested: February 2021

Clean Air Index: 4.6 / 10
Energy Efficiency Index: 4.7 / 10
Greenhouse Gas Index: 4 / 10

The Mazda CX-30 SkyActiv-X 180 2.0-litre petrol manual received a 2.5 star rating from Green NCAP in February 2021.

Green NCAP said: “The CX-30 180 petrol employs Mazda’s Skyactiv-X technology, with a very high compression ratio and lean fuel mixture to try to reduce emissions. This is combined with a 24-volt mild hybrid system to improve fuel efficiency.

“Together with the exhaust after-treatment – three-way catalyst, exhaust gas recirculation and a gasoline particulate filter – the car shows generally low values of pollutant emissions. The weakness is at high engine loads where values of carbon monoxide and carbon dioxide become elevated. This limits the scores in the Clean Air and Greenhouse Gas indexes.

“Overall, the CX-30 scores similarly across the three areas of assessment and emerges with a solid 2½ star rating.”

This rating only applies to the SkyActiv-X 180 2.0-litre petrol manual version of the Mazda MX-30, and does not imply similar ratings for other engine and gearbox combinations in the range.

The Mazda CX-30 is a relatively affordable car to own and run, according to whole-life cost numbers provided exclusively to The Car Expert by our data partner, Clear Vehicle Data.

While the crossover’s fuel economy is fairly average, its insurance premiums are estimated to be on the cheaper side, and its servicing and maintenance costs should be pretty affordable over the first five years of ownership.
