GH-NB8C
Listed 2004–2005. The GH prefix (our explanation, not MLIT’s) means certified to Japan’s 2000 emissions rules, with no low-emission rating. Check GH-NB8C against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| BP1,839 cc petrol | 4-speed automatic | rear-wheel drive | 1,080 kg | — | 11.4 km/L32 mpg, Japanese 10-15 mode test | 2004–2005 |

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.
Check an NB8C before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start NB8C-, 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 NB8C have?
MLIT lists the Mazda Roadster NB8C with BP 1,839 cc petrol.
What fuel economy does the NB8C get?
Officially between 11.4 and 13 km/L (about 32–37 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 NB8C?
Between 1,060 and 1,120 kg kerb weight, depending on the version.
Is GH-NB8C the same as NB8C?
Yes. GH-NB8C is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and NB8C is the model code. The chassis number starts with NB8C-.
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.
