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.
GH-GDB
Listed 2004–2007. The GH prefix (our explanation, not MLIT’s) means certified to Japan’s 2000 emissions rules, with no low-emission rating. Check GH-GDB against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| EJ201,994 cc petrol | 6-speed manual | four-wheel drive | 1,320–1,460 kg | — | 10.2–10.4 km/L29 mpg, Japanese 10-15 mode test | 2004–2007 |
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 GDB before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start GDB-, 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 GDB have?
MLIT lists the Subaru Impreza GDB with EJ20 1,994 cc petrol.
What fuel economy does the GDB get?
Officially between 10.2 and 10.4 km/L (about 29–29 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 GDB?
Between 1,320 and 1,460 kg kerb weight, depending on the version.
Is GH-GDB the same as GDB?
Yes. GH-GDB is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and GDB is the model code. The chassis number starts with GDB-.
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.
