5AA-MA37S
Listed 2021–2025. 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-MA37S against ULEZ and clean air zones.

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 MA37S before you buy
Make sure the car is what the advert says: the chassis number on the V5C should start MA37S-, 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 MA37S have?
MLIT lists the Suzuki Solio MA37S with K12C 1,242 cc petrol or K12C-WA05A 1,242 cc petrol.
What fuel economy does the MA37S get?
Officially between 18.4 and 22.4 km/L (about 52–63 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 MA37S?
Between 1,000 and 1,040 kg kerb weight, depending on the version.
Is 5AA-MA37S the same as MA37S?
Yes. 5AA-MA37S is the full model type: the letters before the hyphen are Japan’s emissions code, which changed as the rules were tightened, and MA37S is the model code. The chassis number starts with MA37S-.
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 Suzuki model codes.
