DBA-GSE20
Listed 2006–2014. The DBA prefix (our explanation, not MLIT’s) means petrol passenger car certified to Japan’s 2005 emissions rules, 75% below their limits. Check DBA-GSE20 against ULEZ and clean air zones.
| Engine | Gearbox | Drive | Weight | Seats | Fuel economy | Listed |
|---|---|---|---|---|---|---|
| 4GR2,499 cc petrol | 6-speed automatic | rear-wheel drive | 1,530–1,740 kg | 4–5 | 11.2–12.2 km/L32–34 mpg, Japanese 10-15 mode test | 2006–2014 |

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.
GSE20 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 | GSE20-2532822 to 2533646 |
From the JAMA chassis number lists: 車台番号一覧表. We keep only the chassis code, serial ranges and year. JAMA calls them reference information, not a certificate.
Check a GSE20 before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start GSE20-, 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 fuel economy does the GSE20 get?

Is DBA-GSE20 the same as GSE20?
Yes. DBA-GSE20 is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and GSE20 is the model code. The chassis number starts with GSE20-.
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 Lexus model codes.
