Safety

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 Ioniq Electric doesn’t offer a front parking aid.

Both the Volt and the Ioniq Electric 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.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its headlight’s “Good” to “Acceptable” rating, the Insurance Institute for Highway Safety grants the Volt the rating of “Top Pick” for 2018, a rating granted to only 88 vehicles tested by the IIHS. The Ioniq Electric has not been tested, yet.

Warranty

Chevrolet pays for scheduled maintenance on the Volt for 2 years and 24,000 miles. Chevrolet will pay for oil changes, lubrication and any other required maintenance (up to 2 oil changes). Hyundai doesn’t pay scheduled maintenance for the Ioniq Electric.

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.

Engine

The Volt’s 1.5 DOHC 4 cyl. hybrid produces 31 more horsepower (149 vs. 118) and 79 lbs.-ft. more torque (294 vs. 215) than the Ioniq Electric’s electric motor.

A full recharge at a conventional charging station can take up to 4 hours and 25 minutes.

Tires and Wheels

For better traction, the Volt has larger tires than the Ioniq Electric (215/50R17 vs. 205/55R16).

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 Ioniq Electric’s standard 55 series tires.

For better ride, handling and brake cooling the Volt has standard 17-inch wheels. Only 16-inch wheels are available on the Ioniq Electric.

Suspension and Handling

The Volt Premier handles at .86 G’s, while the Ioniq Electric pulls only .77 G’s of cornering force in a Motor Trend skidpad test.

The Volt Premier executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the Ioniq Electric (26.9 seconds @ .63 average G’s vs. 28.2 seconds @ .59 average G’s).

Ergonomics

The Volt has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Ioniq Electric doesn’t offer a remote starting system.

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 Ioniq Electric’s rear power window switches have to be held the entire time to open 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 Ioniq Electric can only operate the windows from inside the vehicle, with the ignition on.

While driving with high beams on, sensitive light sensors available for the Volt Premier detect other vehicles which could be blinded and automatically switch to low beams. The Ioniq Electric doesn’t offer automatic dimming high beams.

Both the Volt and the Ioniq Electric 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 Ioniq Electric.

On extremely cold winter days, the Volt’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Ioniq Electric doesn’t offer a heated steering wheel.

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 Ioniq Electric doesn’t offer an automated parking system.

Recommendations

The Chevrolet Volt outsold the Hyundai Ioniq by 82% during 2017.
