Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Ford Focus have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet Sonic doesn’t offer pretensioners for the rear seat belts.

The Focus Titanium has standard parking sensors to help warn drivers about vehicles, pedestrians or other obstacles behind or, optionally, in front of their vehicle. The Focus Titanium also has a standard backup monitor to help drivers see any and all obstacles behind their vehicle. The Sonic doesn’t offer any parking assist system.

Both the Focus and the Sonic have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front-wheel drive, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Reliability Comparison

To reliably start during all conditions and help handle large electrical loads, the Focus has a standard 590-amp battery. The Sonic’s 438-amp battery isn’t as powerful.

J.D. Power and Associates’ 2012 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Ford vehicles are more reliable than Chevrolet vehicles. J.D. Power ranks Ford 8th in reliability, above the industry average. With 11 more problems per 100 vehicles, Chevrolet is ranked 13th.

Engine Comparison

The Focus’ 2.0 DOHC 4 cyl. produces 22 more horsepower (160 vs. 138) and 21 lbs.-ft. more torque (146 vs. 125) than the Sonic’s standard 1.8 DOHC 4 cyl. The Focus’ 2.0 DOHC 4 cyl. produces 22 more horsepower (160 vs. 138) than the Sonic’s optional 1.4 turbo 4 cyl.

Tires and Wheels Comparison

For better traction, the Focus Titanium’s optional tires are larger than the largest tires available on the Sonic (235/40R18 vs. 205/55R16).

The Focus Titanium’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Sonic LTZ/RS’ 50 series tires.

For better ride, handling and brake cooling the Focus Titanium offers optional 18-inch wheels. The Sonic’s largest wheels are only 17-inches.

The Focus Titanium offers an optional full size spare tire so your trip isn’t interrupted by a flat. A full size spare isn’t available on the Sonic, it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

Suspension and Handling Comparison

For superior ride and handling, the Ford Focus has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Chevrolet Sonic has a rear torsion beam axle, with a semi-independent rear suspension.

The Focus has standard front and rear stabilizer bars, which help keep the Focus flat and controlled during cornering. The Sonic’s suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the Focus’ wheelbase is 4.9 inches longer than on the Sonic (104.3 inches vs. 99.4 inches).

For better handling and stability, the track (width between the wheels) on the Focus is 1.8 inches wider in the front and 1.4 inches wider in the rear than on the Sonic.

The Focus’ front to rear weight distribution is more even (58.5% to 41.5%) than the Sonic’s (62.5% to 37.5%). This gives the Focus more stable handling and braking.

The Focus Titanium 5dr Hatchback handles at .91 G’s, while the Sonic LTZ Hatchback pulls only .84 G’s of cornering force in a Road & Track skidpad test.

Chassis Comparison

For excellent aerodynamics, the Focus has standard flush composite headlights. The Sonic has recessed headlights that spoil its aerodynamic shape and create extra drag.

The front grille of the Focus uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Sonic doesn’t offer active grille shutters.

Passenger Space Comparison

Because it has more passenger and cargo room, the Focus 5dr Hatchback is rated a Compact car by the EPA, while the Sonic Hatchback is rated a Small Station Wagon.

The Focus Sedan has .1 inches more front legroom, 2.5 inches more front hip room, 2.2 inches more front shoulder room, .2 inches more rear headroom, 1.1 inches more rear hip room and .7 inches more rear shoulder room than the Sonic Sedan.

The Focus 5dr Hatchback has .1 inches more front legroom, 2.5 inches more front hip room, 2.2 inches more front shoulder room, 1.1 inches more rear hip room and .7 inches more rear shoulder room than the Sonic Hatchback.

Cargo Capacity Comparison

The Focus 5dr Hatchback has a much larger cargo area than the Sonic Hatchback with its rear seat up (23.8 vs. 19 cubic feet).

Ergonomics Comparison

The Focus’ standard power windows allow the driver or passenger to lower and raise the windows without leaning over or being distracted. Power windows are only available on the Sonic LT/LTZ/RS.

The Focus Titanium’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Sonic LT/LTZ/RS’ passenger windows don’t open or close automatically.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the available exterior keypad. The Sonic doesn’t offer an exterior keypad entry system, and its OnStar ® can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

Intelligent Access standard on the Focus Titanium allows the driver to unlock the doors, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the car in bad weather or making a hurried start to your trip. The Chevrolet Sonic doesn’t offer an advanced key system.

The Focus has standard power remote mirrors. The Sonic LS doesn’t offer either a remote driver side or passenger side mirror. The driver will have to roll down the windows and reach across the car to adjust the mirrors.

The Focus’ optional rear view mirror has an automatic dimming feature. This mirror can be set to automatically darken quickly when headlights shine on it, keeping following vehicles from blinding or distracting the driver. The Sonic doesn’t offer the luxury of an automatic dimming rear view mirror.

The Focus offers an optional center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The Sonic doesn’t offer a rear seat center armrest.

The Focus (except S)’s optional dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Sonic doesn’t offer dual zone air conditioning.

The Focus (except S)’s optional automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Sonic doesn’t offer automatic air conditioning.

For greater rear passenger comfort, the Focus has standard rear heat vents to keep rear occupants more comfortable. The Sonic doesn’t offer rear vents.

The Focus’ available GPS navigation system has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service available in a limited number of metro areas.) The Sonic’s available navigation system doesn’t offer real-time traffic updates.

The Focus Titanium’s optional Active Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Sonic doesn’t offer an automated parking system.

Economic Advantages Comparison

Insurance will cost less for the Focus owner. The Car Book by Jack Gillis rates the Focus with a number “3” insurance rate while the Sonic is rated higher at a number “5” rate.

The Focus will cost the buyer less in the long run because of its superior resale value. Kiplinger’s estimates that the Focus will retain a greater percentage of its original price after two and four years than the Sonic.
