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.
QNC21 build year by chassis number
Japan’s carmakers list the chassis numbers each code was built with every year from 2015. Find the serial below, or use the build year finder.
| Built | Chassis numbers |
|---|---|
| 2015 | QNC21-111921 to 113361 |
| 2016 | QNC21-113362 to 114212 |

Check a QNC21 before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start QNC21-, 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 CBA-QNC21 the same as QNC21?

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 Toyota model codes.
