For enhanced safety, the front seat shoulder belts of the Hyundai Sonata Hybrid are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Chevrolet Volt doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sonata Hybrid are reminded to check the back seat if they opened the rear door before starting out. The Volt doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The Sonata Hybrid Limited has standard Reverse Collision-Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Volt doesn’t offer backup collision prevention brakes.

The Sonata Hybrid Limited has a standard Around View Monitor to allow the driver to see objects all around the vehicle on a screen. The Volt only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The Sonata Hybrid’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Volt doesn’t offer a driver alert monitor.

Both the Sonata Hybrid and the Volt 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 and rearview cameras.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Sonata Hybrid the rating of “Top Pick” for 2020, a rating granted to only 30 vehicles tested by the IIHS. The Volt has not been fully tested, yet.

The Sonata Hybrid SEL/Limited has a standard space-saver spare (not available on Blue) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Volt; it requires you to depend on roadside assistance and your vehicle will have to be towed.

For superior ride and handling, the Hyundai Sonata Hybrid 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 Volt has a rear torsion beam axle, with a semi-independent rear suspension.

The Sonata Hybrid has standard front and rear gas-charged shocks for better control over choppy roads. The Volt’s suspension doesn’t offer gas-charged shocks.

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

For a smoother ride and more stable handling, the Sonata Hybrid’s wheelbase is 5.7 inches longer than on the Volt (111.8 inches vs. 106.1 inches).

For better handling and stability, the average track (width between the wheels) on the Sonata Hybrid is 3.8 inches wider in the front and 2.3 inches wider in the rear than the track on the Volt.

Because it has more passenger and cargo room, the EPA rates the Sonata Hybrid a Large car, while the Volt is rated a Compact.

The Sonata Hybrid has 14.1 cubic feet more passenger volume than the Volt (104.4 vs. 90.3).

The Sonata Hybrid has 2.2 inches more front headroom, 4 inches more front legroom, .9 inches more front hip room, 1.4 inches more front shoulder room, 2.6 inches more rear headroom, .1 inches more rear legroom, 3.1 inches more rear hip room and 2.9 inches more rear shoulder room than the Volt.

The Sonata Hybrid has a larger trunk than the Volt (16 vs. 10.6 cubic feet).

A standard locking glovebox keeps your small valuables safer in the Sonata Hybrid. The Volt doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, just waiting momentarily behind the back bumper can open the Sonata Hybrid’s trunk, leaving your hands completely free. The Volt doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The Sonata Hybrid uses gas struts to support the hood for easier service access. The Volt uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

When two different drivers share the Sonata Hybrid Limited, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, outside mirror angle, climate settings and radio stations. The Volt doesn’t offer a memory system.

The Sonata Hybrid Limited has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Volt doesn’t offer a heads-up display.

The Sonata Hybrid SEL/Limited’s front power windows both open or close with one touch of the switches. The Volt’s front passenger window doesn’t close automatically.

The Sonata Hybrid’s speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Volt’s manually variable intermittent wipers have to be constantly adjusted.

When the Sonata Hybrid Limited is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Volt’s mirrors don’t automatically adjust for backing.

Standard air-conditioned seats in the Sonata Hybrid Limited keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Volt doesn’t offer air-conditioned seats.

The Sonata Hybrid’s standard 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 Volt doesn’t offer dual zone air conditioning.

Both the Sonata Hybrid and the Volt offer rear vents. For greater rear passenger comfort, the Sonata Hybrid SEL/Limited has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter.
