The Chevrolet Sonic 1.6 is not widely available in North America; the U.S. and other major markets typically offered the Sonic with 1.4-liter turbocharged or 1.8-liter naturally aspirated engines[2]. However, direct EPA ratings for a 1.6-liter engine are rarely published for the Sonic in these regions. For markets where the Sonic (or Aveo) 1.6 was sold, the city/highway fuel consumption is generally rated at 27/35 mpg (manual) and 25/34 mpg (automatic)—these numbers are based on the closely related Chevrolet Aveo with the 1.6L engine[2].
For comparison, the 1.8-liter engine in the Sonic achieves EPA estimates of 26/35 mpg (manual) and 25/35 mpg (automatic), while the more efficient 1.4-liter turbo variant achieves up to 29/40 mpg (manual) and 27/37 mpg (automatic)[2][4][6]. Real-world mileage may vary based on driving style, vehicle condition, and market-specific tuning.
If you are considering a Sonic 1.6 model from markets outside the U.S., consult your regional Chevrolet documentation for exact consumption figures, as these may vary slightly from the EPA-derived numbers quoted above.
