For 2013, Chevrolet added the sporty RS hatchback to the Sonic lineup. This sporty subcompact with a turbo four-cylinder engine handled child-safety seats surprisingly well. The Sonic also comes as a sedan. Although the hatch is 14.1 inches shorter than the sedan, the rear legroom is 34.6 inches for both body styles.How many car seats fit in the second row? Two

About Cars.com's Car Seat Checks
Editors Jennifer Geiger and Jennifer Newman are certified child safety seat installation technicians.
For the Car Seat Check, we use a Graco SnugRide 30 infant-safety seat, a Britax Roundabout convertible seat and Graco TurboBooster seat. The front seats are adjusted for a 6-foot driver and a 5-foot-8 passenger. The three child seats are installed in the second row. The booster seat sits behind the driver's seat, and the infant and convertible seats are installed behind the front passenger seat.
We also install the forward-facing convertible in the second row's middle seat with the booster and infant seat in the outboard seats to see if three car seats will fit; a child sitting in the booster seat must be able to reach the seat belt buckle. If there's a third row, we install the booster seat and a forward-facing convertible.
Parents should also remember that they can use the Latch system or a seat belt to install a car seat.
