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 are reminded to check the back seat if they opened the rear door before starting out. The Impala doesn’t offer a back seat reminder.

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

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

The Sonata’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 Impala doesn’t offer a driver alert monitor.

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

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Hyundai Sonata is safer than the Impala:

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 the rating of “Top Pick” for 2020, a rating granted to only 30 vehicles tested by the IIHS. The Impala is not a “Top Pick.”

The Sonata comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Impala’s 3-year/36,000-mile basic warranty expires 2 years and 24,000 miles sooner.

Hyundai’s powertrain warranty covers the Sonata 5 years and 40,000 miles longer than Chevrolet covers the Impala. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Impala ends after only 5 years or 60,000 miles.

The Sonata’s corrosion warranty is 1 year and unlimited miles longer than the Impala’s (7/unlimited vs. 6/100,000).

Hyundai pays for scheduled maintenance on the Sonata for 3 years and 30,000 miles. Hyundai will pay for oil changes, lubrication and any other required maintenance. Chevrolet only pays for the first scheduled maintenance visit on the Impala.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Hyundai vehicles are better in initial quality than Chevrolet vehicles. J.D. Power ranks Hyundai third in initial quality, above the industry average. With 14 more problems per 100 vehicles, Chevrolet is ranked 6th.

From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Hyundai vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Hyundai 19 places higher in reliability than Chevrolet.

On the EPA test cycle the Sonata SEL Plus/Limited turbo 4 cyl. gets better fuel mileage than the Impala (27 city/36 hwy vs. 19 city/28 hwy).

In heavy traffic or at stoplights the Sonata SE’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Impala doesn’t offer an automatic engine start/stop system.

An eight-speed automatic is standard on the Hyundai Sonata, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Impala.

For better handling and stability, the average track (width between the wheels) on the Sonata is 1.8 inches wider in the front and 2.3 inches wider in the rear than the track on the Impala.

The Sonata Limited handles at .89 G’s, while the Impala LT pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Sonata’s turning circle is 2.9 feet tighter than the Impala’s (35.9 feet vs. 38.8 feet).

The Hyundai Sonata may be more efficient, handle and accelerate better because it weighs about 450 to 600 pounds less than the Chevrolet Impala.

The Sonata is 8.4 inches shorter than the Impala, making the Sonata easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while at idle, the interior of the Sonata Limited is quieter than the Impala LT (37 vs. 38 dB).

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

The Sonata 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 Impala doesn’t offer a heads-up display.

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

The Sonata’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Impala’s manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Sonata’s available headlights were rated “Good” by the IIHS, while the Impala’s headlights are rated “Poor.”

While driving with high beams on, sensitive light sensors standard on the Sonata detect other vehicles which could be blinded and automatically switch to low beams. The Impala doesn’t offer automatic dimming high beams.

When the Sonata 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 Impala’s mirrors don’t automatically adjust for backing.

The Sonata Limited’s Remote Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Impala doesn’t offer an automated parking system.

The Hyundai Sonata outsold the Chevrolet Impala by almost two to one during 2019.
