The Volt offers optional Park Assist to help warn the driver about vehicles, pedestrians or other obstacles behind or, for the Volt Premier in front of the vehicle. The Sonata Hybrid doesn’t offer a front parking aid.

Both the Volt and the Sonata Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.


Chevrolet pays for the first scheduled maintenance on the Volt. Chevrolet will pay for the first oil change, lubrication and any other required maintenance during the first 12 months. Hyundai doesn’t pay scheduled maintenance for the Sonata Hybrid.

There are almost 4 times as many Chevrolet dealers as there are Hyundai dealers, which makes it much easier should you ever need service under the Volt’s warranty.


The Volt’s 1.5 DOHC 4 cyl. hybrid produces 23 lbs.-ft. more torque (294 vs. 271) than the Sonata Hybrid’s 2.0 DOHC 4 cyl. hybrid.

Fuel Economy and Range

On the EPA test cycle the Volt gets better fuel mileage than the Sonata Hybrid:




Sonata Hybrid



Running on electricity

113 city/99 hwy MPGe




Running on gas

43 city/42 hwy

40 city/46 hwy





39 city/44 hwy


The Volt can drive on battery power alone for up to 53 miles. The Sonata Hybrid must run its internal combustion engine to move.


The Volt has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Sonata Hybrid doesn’t offer a CVT.

Tires and Wheels

For better traction, the Volt has larger tires than the Sonata Hybrid (215/50R17 vs. 205/65R16).

The Volt’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Sonata Hybrid’s standard 65 series tires. The Volt’s tires are lower profile than the Sonata Hybrid’s optional 55 series tires.

For better ride, handling and brake cooling the Volt has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Sonata Hybrid.

The Volt has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Sonata Hybrid doesn’t offer vehicle monitored tire inflation.


The Volt is 10.7 inches shorter than the Sonata Hybrid, making the Volt easier to handle, maneuver and park in tight spaces.

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


The Volt’s front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Sonata Hybrid’s standard power windows’ passenger windows don’t open automatically. The Sonata Hybrid Limited’s rear power window switches have to be held the entire time to lower them fully.

On a hot day the Volt’s driver can lower all the windows from a distance using the keyless remote. The driver of the Sonata Hybrid can only operate the windows from inside the vehicle, with the ignition on.

Both the Volt and the Sonata Hybrid offer available heated front seats. The Volt Premier also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Sonata Hybrid.

The Volt Premier’s Automatic Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Sonata Hybrid doesn’t offer an automated parking system.
