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.
3BA-GU6
Listed 2024–2026. The 3BA prefix (our explanation, not MLIT’s) means petrol passenger car certified to Japan’s 2018 emissions rules. Check 3BA-GU6 against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| FB201,995 cc petrol | CVT automatic | front-wheel drive | 1,380–1,390 kg | 5 | 15.8 km/L45 mpg, Japanese JC08 test | 2024–2026 |
| FB201,995 cc petrol | CVT automatic | front-wheel drive | 1,380–1,390 kg | 5 | 14 km/L40 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 GU6 before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start GU6-, 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 GU6 have?
MLIT lists the Subaru Impreza GU6 with FB20 1,995 cc petrol.
What fuel economy does the GU6 get?
Officially between 14 and 15.8 km/L (about 40–45 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 GU6?
Between 1,380 and 1,390 kg kerb weight, depending on the version.
Is 3BA-GU6 the same as GU6?
Yes. 3BA-GU6 is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and GU6 is the model code. The chassis number starts with GU6-.
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 Subaru model codes.
