Fuel economy is from Japan’s official tests and is usually better than you’ll see on UK roads. MLIT doesn’t list power or torque.

3DF-JCN4E26

Listed 2023–2026. The 3DF prefix (our explanation, not MLIT’s) means diesel goods vehicle or bus certified to Japan’s 2018 emissions rules. Check 3DF-JCN4E26 against ULEZ and clean air zones.

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.

JCN4E26 build year by chassis number

Check a JCN4E26 before you buy

Make sure the car is what the advert says: the chassis number on the V5C should start JCN4E26-, 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.

Is 3DF-JCN4E26 the same as JCN4E26?

Yes. 3DF-JCN4E26 is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and JCN4E26 is the model code. The chassis number starts with JCN4E26-.

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 Isuzu model codes.
