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.
6AA-RT6
Listed 2019–2023. The 6AA prefix (our explanation, not MLIT’s) means hybrid passenger car certified to Japan’s 2018 emissions rules, 75% below their limits. Check 6AA-RT6 against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| LFB1,993 cc hybrid | not stated | four-wheel drive | 1,660–1,700 kg | 5 | 25 km/L71 mpg, Japanese JC08 test | 2019–2023 |

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 RT6 before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start RT6-, 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 RT6 have?
MLIT lists the Honda CR-V RT6 with LFB 1,993 cc hybrid.
What fuel economy does the RT6 get?
Officially between 20.2 and 25 km/L (about 57–71 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 RT6?
Between 1,660 and 1,700 kg kerb weight, depending on the version.
Is 6AA-RT6 the same as RT6?
Yes. 6AA-RT6 is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and RT6 is the model code. The chassis number starts with RT6-.
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.
