Each row is one version as MLIT lists it. A version can appear twice when MLIT gave figures on two tests that year. Low-emission stars and trim names aren’t shown. MLIT gives fuel economy in km/L; the mpg figures are our conversion to UK gallons. Japanese tests are gentler than real UK driving, so expect less.
MS31S build year by chassis number
Japan’s carmakers list the chassis numbers each code was built with every year from 2015. Find the serial below, or use the build year finder.

From the JAMA chassis number lists: 車台番号一覧表. We keep only the chassis code, serial ranges and year. JAMA calls them reference information, not a certificate.
Check an MS31S before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start MS31S-, and the engine and gearbox should match one of the versions above. Our free check reads the UK MOT history and compares it with the chassis code.

MLIT lists the Mazda Flair Crossover MS31S with R06A 658 cc petrol.
What fuel economy does the MS31S get?
Officially between 23.2 and 29.2 km/L (about 66–82 mpg), depending on the version, on Japan’s own tests. Real-world figures are usually lower, especially against the older 10-15 mode test.
How heavy is the MS31S?
Between 750 and 870 kg kerb weight, depending on the version.
Is DBA-MS31S the same as MS31S?
Yes. DBA-MS31S is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and MS31S is the model code. The chassis number starts with MS31S-.
About these figures
The model types, engine codes, capacities, gearboxes, drive, weights, seats and km/L figures are copied from MLIT’s yearly lists of cars on sale in Japan each March, so “listed” years are list years, not exact production dates. The English model names, mpg conversions, emissions code explanations and chassis number matching are ours. Lists before 2013 were printed as PDFs that we read by machine; where an older list gives an engine code that doesn’t match its capacity, we’ve used the figure the same model type has in other years. Check anything that matters against the car’s own papers. Spotted a mistake? Email [email protected]. All Mazda model codes.
