5BA-AAZA25
Listed 2022–2025. The 5BA prefix (our explanation, not MLIT’s) means petrol passenger car certified to Japan’s 2018 emissions rules, 50% below their limits. Check 5BA-AAZA25 against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| A25A2,487 cc petrol | 8-speed automatic | four-wheel drive | 1,680–1,750 kg | 5 | 13.5–13.9 km/L38–39 mpg, WLTC test | 2022–2025 |
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 AAZA25 before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start AAZA25-, 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 5BA-AAZA25 the same as AAZA25?

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 Lexus model codes.
