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.
6BA-JF5
Listed 2024–2026. The 6BA prefix (our explanation, not MLIT’s) means petrol passenger car certified to Japan’s 2018 emissions rules, 75% below their limits. Check 6BA-JF5 against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| S07B658 cc petrol | CVT automatic | front-wheel drive | 910–960 kg | 4 | 24.5–26.1 km/L69–74 mpg, Japanese JC08 test | 2024–2026 |
| S07B658 cc petrol | CVT automatic | front-wheel drive | 910–960 kg | 4 | 20.2–21.6 km/L57–61 mpg, WLTC test | 2024–2026 |
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 a JF5 before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start JF5-, 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 JF5 have?
MLIT lists the Honda N-BOX Custom / N-BOX JF5 with S07B 658 cc petrol.
What fuel economy does the JF5 get?
Officially between 20.2 and 26.1 km/L (about 57–74 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 JF5?
Between 910 and 960 kg kerb weight, depending on the version.
Is 6BA-JF5 the same as JF5?
Yes. 6BA-JF5 is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and JF5 is the model code. The chassis number starts with JF5-.
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 Honda model codes.
