How many miles per gallon does a Chevy Onix get?
The Onix’s miles-per-gallon figure isn’t fixed; it varies by market, engine, and fuel choice. In gasoline form, most recent Onix models post roughly 28–40 miles per gallon (mpg US) in combined driving, with turbo variants tending toward the higher end and ethanol blends pulling numbers down. Note that the Onix is not commonly sold in the United States, so official EPA ratings are not widely published; instead, ratings come from local testing in Latin American markets such as Inmetro in Brazil and from owner reports.
Variant-by-variant outlook
The following ranges reflect typical combined fuel economy for common Onix configurations in markets where the car is sold. They illustrate how engine choice, fuel type, and transmission influence mpg.
- 1.0-liter naturally aspirated gasoline: approximately 28–33 mpg (combined, US standard).
- 1.0-liter turbocharged gasoline: approximately 33–40 mpg (combined).
- Flex-fuel (ethanol/gasoline blends common in Brazil and other Latin American markets): approximately 23–28 mpg (combined) depending on ethanol content and fuel mix.
These ranges should be interpreted as guidelines. Real-world results vary with driving style, climate, maintenance, and the specific model year and trim.
Important distinctions: test standards vs. real-world use
Because the Onix is primarily sold outside the United States, official EPA fuel economy numbers are not always available in the same format as for U.S.-market cars. Brazil’s Inmetro and other Latin American testing programs, as well as user-reported driving data, provide the practical baseline many buyers rely on. When evaluating a specific Onix, check the official rating for the exact trim and market, and consider real-world reviews for typical results.
Bottom line
In short, you can expect Onix mpg to sit in the mid-30s mpg US range for gasoline versions (roughly 33–40 mpg, depending on turbo usage), with ethanol-blend versions lower. Always confirm with local specifications for your market and model year.
Summary
The Chevy Onix does not have a single universal mpg figure; its efficiency depends on engine, fuel type, and market. Across common gasoline configurations, combined fuel economy generally falls in the high 20s to low 40s mpg US, with turbo variants leaning toward the higher end and ethanol blends reducing mpg. For precise numbers, consult the official figures from your market and the specific trim details, along with real-world user reports.
