2018 Chevrolet Sonic Review

Joe Tralongo is an author specializing in finding those unique aspects of each car that everyday drivers want to know about. He began his career in 2000 as Kelley Blue Book’s first in-house automotive reviewer. After a long career as a freelancer, Joe returned to the Cox Automotive team in 2022 and remains a dedicated part of the KBB team, providing reviews that are both informative and easy to digest. Now living in Montana, Joe continues to enjoy driving and learning about new cars. In his off time, Joe collects and restores classic 1970s American cars.

Pros

If you find most small-crossover SUVs too expensive and fuel thirsty, yet you need room for passengers and/or cargo, the 2018 Chevrolet Sonic can help bridge the gap. Affordable, efficient and offering the latest in infotainment and driver safety, the Sonic breaks the small-car stereotype.

Cons

If you regularly travel with friends, family, dogs or lots of gear, the Sonic may be too small to accommodate all your needs. You’ll find the Sonic’s optional driver-assist features standard on the Toyota Yaris, while a base Subaru Impreza delivers more room, features and standard all-wheel drive for around $20,000.

What's New?

The Chevy Sonic receives some minor tweaks for 2018, mostly centered around some package shuffling and new color options.

In an age where tiny houses are all the rage, it only makes sense someone builds a tiny car to park in the driveway. The 2018 Chevrolet Sonic is just such a car, slightly larger and more powerful than the Chevy Spark, but not quite as big as the compact Cruze. In this sweet spot, the 2018 Sonic offers plenty to like, including a very low starting price, high-tech options like Apple CarPlay and a Wi-Fi hotspot, not to mention sporty styling and an available turbocharged engine. Base models lack even the most basic accommodations (you’ll have to crank open the windows), but when comparably equipped, the Sonic remains competitive against cars like the Kia Rio, Hyundai Accent and Toyota Yaris.

2018 Chevrolet Sonic Pricing

2018 Chevrolet Sonic pricing starts at $7,021 for the Sonic LS Sedan 4D, which had a starting MSRP of $17,395 when new. The range-topping 2018 Sonic Premier Hatchback 4D starts at $11,928 today, originally priced from $22,195.

The Kelley Blue Book Fair Purchase Price for any individual used vehicle can vary greatly according to mileage, condition, location, and other factors. The prices here reflect what buyers are currently paying for used 2018 Chevrolet Sonic models in typical condition when purchasing from a dealership. These prices are updated weekly.

Driving the Chevrolet Sonic

As subcompact cars go, the 2018 Chevy Sonic places an equal emphasis on efficiency and fun-to-drive dynamics. The Sonic delivers a stable and smooth ride, precise steering and a nimble suspension that can be upgraded with Chevy’s enthusiast-oriented FE3 Sport suspension package. We found the Sonic more engaging than the Toyota Yaris or Kia Rio, but not quite as lively as the Ford Fiesta. Then again, few of its competitors offer the option of a turbocharged engine, another factor in the Sonic’s playful demeanor. If you go with the standard 1.8-liter engine, you won’t be disappointed with the driving experience, but it doesn’t offer that added punch that makes turbocharged cars so much fun. In our short time behind the Sonic’s wheel, we came to think of it less as a subcompact commuter car and more a poor-man’s Mini Cooper. We also appreciate the driver-seat’s built-in right-side armrest.

Interior Comfort

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. That’s still less than a Honda Fit hatchback, but the Chevy has more space than the Honda with the rear seats up — 19 cubic feet vs. the Fit’s 16.6. We also like the handy dual-glove-box arrangement.

Exterior Styling

All 2018 Chevy Sonics have small footprints and tidy proportions. We favor the design of the hatchback, which reminds us of classy-yet-practical European models, featuring hidden rear-door handles in the black areas of the C-pillars that make the Sonic hatchback appear more like a 2-door. For traditionalists, the sedan offers a large trunk. Both versions benefit from an attractive face that makes the Sonic appear wider and better integrates the headlight housings. The RS package, standard on hatchbacks and available on sedans, features a unique body kit and rocker moldings, rear spoiler and other sporty bits.

Favorite Features

CHEVROLET MYLINK
You’ll find some compact cars costing far more that don’t offer the standard audio setup in the 2018 Chevrolet Sonic. Every model includes a 7-inch touch screen that controls Apple CarPlay and Android Auto integration, Bluetooth, OnStar 4G LTE and an available Wi-Fi hotspot.

BIG SAFETY FEATURES
Standard safety features on every Chevy Sonic include 10 airbags, anti-lock brakes and electronic stability control. Optional are forward-collision alert (but not prevention) and lane-departure warning systems.

Standard Features

The 2018 Sonic sedan is available as LS, LT and Premier, while the pricier Sonic hatchback is offered in LT and Premier form. The lowest priced LS Sedan includes some surprisingly sweet features but lacks others. For instance, it includes a robust 7-inch touch-screen infotainment system with CarPlay and Android Auto, rearview camera, built-in 4G LTE Wi-Fi connectivity and remote keyless entry, but lacks cruise control, power windows or power-adjustable mirrors. We recommend the hatchback or stepping up to the LT sedan, which includes a standard turbocharged engine, better-quality cloth seating, 6-speaker audio and those features lacking in base models.

Factory Options

Top-line Sonic Premier models have the most robust set of features, including Leatherette upholstery with heated and power-adjustable front seats, heated steering wheel, 17-inch wheels, sport suspension, fog lights, and the RS package that bundles unique interior and exterior aesthetics. Options include a power sunroof and a lowering-suspension kit to improve handling on LT and Premier models. The option we most recommend — and a great value at $495 — is the Driver Confidence Package that includes forward-collision alert, lane-departure warning and rear-park assist. It, too, is available on all but base LS sedans.

Engine & Transmission

There are two engine choices for the Sonic, each more than merely acceptable. The base 1.8-liter 4-cylinder cranks out good power and is entirely adequate, especially for younger drivers. The pricier alternative is a 1.4-liter turbocharged 4-cylinder that’s sportier and makes more torque, and thus goes quicker, but has as its main advantage a 2-5-mpg gain in highway fuel economy, depending on transmission. For that, the 1.8-liter is available with a 5-speed manual transmission, the turbo 1.4-liter with a 6-speed manual, and both can be matched with a 6-speed automatic. In our experience, we found no reason not to like any of the transmission choices.
