ABA-S331N
Listed 2010–2020. The ABA prefix (our explanation, not MLIT’s) means petrol passenger car certified to Japan’s 2005 emissions rules. Check ABA-S331N against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| KF658 cc petrol | 4-speed automatic | four-wheel drive | 1,010–1,030 kg | 4 | 13.4–14.8 km/L38–42 mpg, Japanese 10-15 mode test | 2010–2012 |
| KF658 cc petrol | 4-speed automatic | four-wheel drive | 1,010–1,050 kg | 4 | 13.4–15.2 km/L38–43 mpg, Japanese JC08 test | 2013–2020 |
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 S331N before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start S331N-, 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.

Questions
What engine does the S331N have?
MLIT lists the Subaru Dias S331N with KF 658 cc petrol.
What fuel economy does the S331N get?
Officially between 13.4 and 15.2 km/L (about 38–43 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 S331N?
Between 1,010 and 1,050 kg kerb weight, depending on the version.
Is ABA-S331N the same as S331N?
Yes. ABA-S331N is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and S331N is the model code. The chassis number starts with S331N-.
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 Subaru model codes.
