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.
5AA-GUD
Listed 2024–2026. The 5AA prefix (our explanation, not MLIT’s) means hybrid passenger car certified to Japan’s 2018 emissions rules, 50% below their limits. Check 5AA-GUD against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| FB201,995 cc hybrid | CVT automatic | front-wheel drive | 1,530–1,580 kg | 5 | 19.3–19.4 km/L55 mpg, Japanese JC08 test | 2024–2026 |
| FB201,995 cc hybrid | CVT automatic | front-wheel drive | 1,530–1,580 kg | 5 | 16.4–16.6 km/L46–47 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.
GUD build year by chassis number

Check a GUD before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start GUD-, 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 GUD have?
MLIT lists the Subaru Impreza / Crosstrek GUD with FB20 1,995 cc hybrid.
What fuel economy does the GUD get?
Officially between 16.4 and 19.4 km/L (about 46–55 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 GUD?
Between 1,530 and 1,580 kg kerb weight, depending on the version.
Is 5AA-GUD the same as GUD?
Yes. 5AA-GUD is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and GUD is the model code. The chassis number starts with GUD-.
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.
