What kind of engine is in a Chevy Sonic?
The Chevy Sonic is equipped with a 1.4-liter turbocharged four-cylinder engine. This engine provides a good balance of power and efficiency for the compact Sonic sedan and hatchback models.
Chevy Sonic Engine Details
The standard engine in the Chevy Sonic is a 1.4-liter Ecotec turbocharged four-cylinder. This engine produces 138 horsepower and 148 lb-ft of torque, which gives the Sonic peppy acceleration and responsive performance around town. The 1.4T engine is paired with either a 6-speed manual or 6-speed automatic transmission.
In addition to the turbocharged 1.4-liter, the Chevy Sonic was also previously available with a naturally aspirated 1.8-liter four-cylinder engine. However, the 1.8L was discontinued after the 2020 model year, leaving the 1.4T as the sole engine option for the Sonic.
Fuel Economy and Performance
The Chevy Sonic with the 1.4T engine and 6-speed manual transmission is rated by the EPA at 28 mpg city, 37 mpg highway, and 32 mpg combined. Models with the 6-speed automatic transmission are slightly less efficient at 26 mpg city, 34 mpg highway, and 29 mpg combined.
In terms of performance, the turbocharged 1.4-liter engine provides a nice boost in power compared to naturally aspirated four-cylinder engines typically found in subcompact cars. The Sonic can accelerate from 0-60 mph in around 8 seconds, which is respectable for the class.
Conclusion
The Chevy Sonic is powered by a 1.4-liter turbocharged four-cylinder engine that delivers a good mix of power, efficiency, and performance for a compact car. This engine has been the sole powertrain option for the Sonic since the 2021 model year.

The Chevy Spark is smaller, more fuel-efficient, and generally less expensive than the Sonic, making it better for city driving and budget-conscious buyers. The Sonic is a larger, more powerful car with more cargo space, but it has lower fuel economy and a higher price point. Both have been discontinued, with the Sonic ending production in 2020 and the Spark in 2022.

Areas of concern
- Cooling system: The stock cooling system is prone to failure, with many owners recommending upgrading parts like the thermostat housing, water outlet, and radiator to more durable aluminum versions.
- Valve cover: A common issue is a leaking valve cover, which can cause a check engine light to come on due to a "lean code" (P0171). This is often caused by cracks or leaks in the boot after the mass air flow sensor or the valve cover itself.
- Transmission: Some models, particularly those with turbochargers, have been linked to transmission problems.
- Other issues: Owners have reported problems with the gear shift breaking, though replacements don't always fix the issue.
Positive aspects
- Average repair costs: The average annual repair cost for the Sonic is about $536$ 536$536, which is lower than average.
- Repair frequency and severity: Repairs are less severe than average, and the frequency of issues is considered average.
- Good fuel economy: The Sonic is known for being good on gas.
- Overall rating: Despite specific model concerns, the Sonic receives an above-average reliability rating of 4.0 out of 5.0 from some sources.
