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.
NCEC 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.
| Built | Chassis numbers |
|---|---|
| 2015 | NCEC-306611 to 306690 |
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 NCEC before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start NCEC-, 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.

What engine does the NCEC have?
MLIT lists the Mazda Roadster NCEC with LF 1,998 cc petrol.
What fuel economy does the NCEC get?
Officially between 11.2 and 13.4 km/L (about 32–38 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 NCEC?
Between 1,090 and 1,170 kg kerb weight, depending on the version.
Is CBA-NCEC the same as NCEC?
Yes. CBA-NCEC is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and NCEC is the model code. The chassis number starts with NCEC-.
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.
