Note: This performance review was created when the 2013 Chevrolet Sonic was new.
Most reviewers think the 2013 Chevrolet Sonic has smooth transmissions, sharp handling and adequate engine power. Some test drivers are disappointed with the Sonic's fuel economy ratings.
The base 2013 Chevrolet Sonic has a 138-horsepower, 1.8-liter, four-cylinder engine. There is also an optional turbocharged 1.4-liter four-cylinder engine that makes 138 horsepower, but produces 23 pound-feet of torque more than the base model. A five-speed manual transmission is standard with the base engine, while a six-speed manual is standard with the turbocharged engine. A six-speed automatic is optional with both. Fuel economy ratings are good, but less than what the Sonic's rivals average. The turbocharged engine averages 27/37 mpg city/highway with the automatic transmission, according to the EPA. Gas mileage is 25/35 mpg with the 1.8-liter engine and automatic transmission.
While test drivers think the base engine shows its weakness when accelerating out of corners, they tend to prefer the optional turbocharged engine because of its higher torque rating, though some say it isn't much faster than the base model. Reviewer opinion of the Sonic's transmissions are divided. One test driver thinks both the manual and automatic transmissions shift smoothly. A different reviewer mentions that the automatic transmission's shifts are slow and rough.
Test drivers give mixed reviews of the 2013 Chevrolet Sonic's handling and braking abilities. Many reviewers report that the Sonic's accurate steering is one of its best qualities, and like that it adapts to different environments, such as parking lots and highways, easily. Other test drivers, however, think the Sonic's steering is too light, which keeps it from being precise. Reviewers also say that overall ride quality is good, though like many small cars, the ride can get rough over uneven pavement. Reviewers say the brakes are strong, though one mentions that the pedal is mushy.
