2018 Chevrolet Sonic Interior Review

Note: This interior review was created when the 2018 Chevrolet Sonic was new.


Interior: 8.1

The 2018 Chevrolet Sonic is roomier than most vehicles this size, treating passengers to reasonably comfortable seats and a generous amount of cargo room. A nice array of technology features is present, but so are lower-grade cabin materials.

  • "Whether sedan or hatchback, the Sonic's 5-passenger interior is eye-pleasing, roomy for its size and has an air of sophistication thanks to the standard 7-inch touch screen that dominates the center front of the cockpit. The rear seat is one of the roomiest in the segment, and the versatile and recommendable hatchback models offer 47.7 cubic feet of cargo room with rear seats folded." -- Kelley Blue Book
  • "Interior materials quality is low, even for a segment where ample amounts of hard plastics in the cabin are common." -- Edmunds (2016)
  • "But the interior is really pretty good for the class, especially the seats. And all the little toys you're getting make it a great deal in that class." -- Jalopnik (2013)


The Sonic seats five people and comes standard with cloth upholstery, a four-way manually adjustable driver's seat, a two-way manually adjustable front passenger seat, and a 60/40-split-folding rear seat. Deluxe cloth upholstery, synthetic leather upholstery, heated front seats with six-way power adjustments, a leather-wrapped steering wheel, and a heated steering wheel are among the seating options.

The Sonic is roomy and comfortable for such a small car. Like many vehicles this size, legroom is limited in the back seat, but it will accommodate grown-ups for brief trips. The front seats are cushy enough to keep you cozy all day long.

For connecting child safety seats, the Sonic has two sets of lower anchors on the outboard seats and as three upper tether anchors. The lower anchors are mounted deep in the seat cushions, and with limited room to move around them, you'll need extra elbow grease to connect a car seat. The three tether anchors, however, are easy to find and use. The IIHS gave the Sonic’s LATCH system a Marginal rating (the second-lowest possible).

  • "When combined, the Sonic's supportive seats, excellent suspension, standard driver armrest -- a rarity in the subcompact market -- and tilt-telescopic steering wheel made for one of the most comfortable rides of any small vehicle we've driven. Over the course of the day, the seats blended into the background and never caused any noticeable dead spots or discomfort." -- Autotrader (2017)
  • "It earns extra points for comfort, however, as even tall drivers can find a driving position that works. Smaller adults should find the rear seats similarly accommodating by segment standards, with decent amounts of head- and legroom." -- Edmunds (2017)
  • "A small but notable detail we appreciate: The driver's seat on all models includes an armrest on the right, which makes longer commutes comfortable." -- Kelley Blue Book (2017)

Interior Features

The 2018 Sonic's standard infotainment system consists of the Chevrolet MyLink interface, a 7-inch touch screen, Apple CarPlay, Android Auto, a four-speaker stereo, Bluetooth phone and audio connectivity, a USB port, and OnStar's built-in Wi-Fi hot spot with 4G LTE internet access. Air conditioning, power door locks, keyless entry, and a rearview camera are also standard. Available features include power windows, cruise control, dual USB ports, satellite radio, a six-speaker stereo, a proximity key, push-button start, a sunroof, forward collision warning, lane departure warning, and rear parking sensors.

The user-friendly infotainment interface is easy to learn, though the screen can occasionally lag. Test drivers praise the car's lengthy list of standard features.

  • "The Sonic's gauges and controls are well laid out and easy to operate. … MyLink's menus are intuitive enough that it doesn't take long for a first-time user to master its functions and controls. Our only gripe is that it sometimes takes a few beats for inputs to be recognized." -- Edmunds (2017)
  • "The nontraditional gauge cluster places a conventional tachometer to the left of a bright blue digital display that collects everything from current speed and direction to average fuel economy and distance driven into one easy-to-read package." -- Autotrader (2016)
  • "Also surprising is the Sonic's impressive list of standard and available features that include streaming Bluetooth audio and GM's impressive MyLink infotainment system that allows for hands-free control of messages, apps and music devices." -- Kelley Blue Book (2015)


The Sonic has ample cargo room. The sedan has a 14.9-cubic-foot trunk, while hatchback versions have 19 cubic feet of room behind the seats. A split-folding rear seat comes standard, for a total cargo capacity of 47.7 cubic feet in the Sonic hatchback.

  • "The sedan's 14.9-cubic-foot trunk is among the largest in the segment and can be expanded further with the standard 60/40-folding rear seatbacks. The Sonic hatchback offers 19 cubic feet with the rear seats up and 47.7 cubic feet with them folded down. That's very good, but bested slightly by the Honda Fit (52.7 cubic feet) and the Kia Rio (49.8 cubic feet)." -- Edmunds (2017)
