Driving Impression

Engine behavior varies considerably. The base engine feels weak, loud and harsh, in stark contrast to the smooth, sporty nature of the turbo four. Clearly, the turbo is a better choice, even offering more satisfying gas mileage.

Turbo-power Sonics are fun to drive, especially with the 6-speed manual gearbox. They handle nicely and feel admirably composed – as solid and sturdy as a bigger car. Chevrolet’s responsive electric power steering provides good feel and helpful weighting. Unlike some rivals, too, the ride is well-controlled rather than coarse and overly active.

Top fuel-economy ratings stem from the 1.4-liter turbo with the 6-speed manual gearbox, EPA-rated at 28/37 mpg City/Highway, or 32 mpg Combined. An automatic transmission drops that rating to 27/35 mpg City/Highway, or 30 mpg Combined.

With a 5-speed manual gearbox, the 1.8-liter engine is EPA-rated at 26/35 mpg City/Highway, or 29 mpg Combined. The 6-speed automatic reduces that estimate to 25/34/28 mpg. Fuel-economy estimates are identical for the hatchback and sedan.

Walk Around

Overall, the Sonic design has aged reasonably well, helped by a modernized front end for the 2017 model year, echoing appearance of recent Chevrolets. The two-element grille includes a large lower intake, with scoop-like openings for available foglamps. Projector-beam headlights are complemented by LED daytime running lights.

The five-door hatchback looks more settled than the sedan, though the blocky trunk is a bit large, lacking in elegance. Considering its seven-year history, the comparatively simple, basic shape of the hatchback isn’t obsolete.

Interior Overview

“”

Front seats are comfortable, but even two passengers in the rear can expect a tight experience. Taller adults are likely to be short on headroom, as well as leg space.

Early Sonics conveyed an econocar aura, but the current cabin is significantly more stylish. During recent years, quite a few subcompact cars have grown bigger, but Chevrolet hasn’t enlarged the Sonic.

Mounted at the center of the straightforward instrument panel is a large speedometer, matched by a slightly smaller tachometer. The infotainment touchscreen sits above big, intuitive rotary knobs that make climate adjustments.

Seat fabrics and abundant black plastic trim, among other interior elements, are appropriate for the subcompact segment. All told, the Sonic comes across as higher in quality than some Asian rivals. Each Sonic also is quiet on the road.

Cargo space is generous with either body style. Sedan trunks hold 14.9 cubic feet, with low liftover height. Hatchbacks promise 19 cubic-foot capacity with the rear seat up, growing to 42.7 cubic feet with the seat folded. A hidden bin is located below the cargo deck.

The hatchback’s load floor is a bit higher than in some competitors, but the Sonic’s relatively upright profile improves its ability to hold tall or long items. Rear seats in each body style flip forward.

Summary

Editor:

“”

Despite its age, the Sonic remains a good choice in the subcompact category, ranking above the pack in design and fuel economy, as well as in safety. Even the modestly equipped Sonic LS isn’t grimly austere. Not many new subcompacts have been emerging lately, but the Sonic is likely to carry on for a while yet. It’s even more affordable than in the past, because of incentives available on such less-popular small cars.
