Compare the2026 Audi A3VS 2026 Hyundai Sonata

The A3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Sonata doesn’t offer pre-crash pretensioners.

Both the A3 and Sonata have child safety locks to prevent children from opening the rear doors. The A3 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Sonata’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Audi A3 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Sonata doesn’t offer a front passenger side knee airbag.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Audi A3 achieved a “Good” rating - the highest possible - in forward collision warning and automatic braking systems, outperforming the Hyundai Sonata, which scored only an “Acceptable” in these critical safety features.

The A3 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Sonata doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The A3 has standard backup collision prevention system that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Sonata doesn’t offer automatic braking for stationary objects directly to the rear.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A3. But it costs extra on the Sonata.

The A3 Premium Plus has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The Sonata only offers a rear monitor.

Both the A3 and the Sonata have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

The A3’s corrosion warranty is 5 years longer than the Sonata’s (12 vs. 7 years).

Audi pays for scheduled maintenance on the A3 for 3 years and 30,000 miles. Audi will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Hyundai doesn’t pay scheduled maintenance for the Sonata.

The Audi A3’s engine uses a cast iron block for durability, while the Sonata’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The A3’s 2.0 turbo 4-cylinder hybrid produces 10 more horsepower (201 vs. 191) and 55 lbs.-ft. more torque (236 vs. 181) than the Sonata’s standard 2.5 DOHC 4-cylinder.

As tested in Consumer Reports the Audi A3 is faster than the Hyundai Sonata 4 cyl.:

	A3	Sonata
Zero to 30 MPH	2.6 sec	3.5 sec
Zero to 60 MPH	6.8 sec	8.7 sec
45 to 65 MPH Passing	4 sec	5.4 sec
Quarter Mile	15.2 sec	16.7 sec
Speed in 1/4 Mile	95 MPH	90 MPH

On the EPA test cycle the A3 gets better mileage than the Sonata:

			MPG
A3
	AWD	2.0 turbo 4-cyl. Hybrid	24 city/34 hwy
Sonata
	FWD	2.5 turbo 4-cyl.	23 city/32 hwy
	AWD	2.5 DOHC 4-cyl.	24 city/33 hwy

Regenerative brakes improve the A3’s fuel efficiency by converting inertia back into energy instead of wasting it. The Sonata doesn’t offer a regenerative braking system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A3 higher (6 out of 10) than the Hyundai Sonata (4 to 6). This means the A3 produces up to 12.1 pounds less smog-producing pollutants than the Sonata every 15,000 miles.

The A3 stops shorter than the Sonata:

	A3	Sonata
60 to 0 MPH	120 feet	127 feet	Consumer Reports
60 to 0 MPH (Wet)	129 feet	143 feet	Consumer Reports

For better traction, the A3 has larger tires than the Sonata (225/45R17 vs. 205/65R16).

The A3’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Sonata SE’s standard 65 series tires.

For better ride, handling and brake cooling the A3 has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Sonata SE.

The A3 Premium Plus handles at .89 G’s, while the Sonata SEL Sport AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The A3 Premium Plus executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the Sonata SEL Sport AWD (26.3 seconds @ .66 average G’s vs. 27.7 seconds @ .61 average G’s).

The A3 is 1 foot, 4.4 inches shorter than the Sonata, making the A3 easier to handle, maneuver and park in tight spaces.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the A3. The Sonata doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier, especially for short adults, the A3 has a standard power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The Sonata doesn’t offer a power trunk, so its trunk has to be closed manually.

The A3 has a 3461 lbs. towing capacity. The Sonata has no towing capacity.

When different drivers share the A3, the optional memory seats and mirrors make it convenient. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Sonata doesn’t offer a memory system.

The A3’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 Sonata’s standard passenger windows don’t open or close automatically. With the Sonata SEL/N Line’s power windows, only the front windows open or close automatically.

If the windows are left open on the A3 the driver can close all of them at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Sonata can only close the windows from inside the vehicle, with the ignition on.

The A3’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 Sonata’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are standard on the A3 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Sonata doesn’t offer heated windshield washer nozzles.

The A3’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Hyundai only offers heated mirrors on the Sonata SEL Sport/N Line.

When the A3 with available tilt-down mirrors is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Sonata’s mirror doesn’t automatically adjust for backing.

The A3’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Sonata offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the Audi A3 and Hyundai Sonata offer exterior mirrors that can be folded to provide convenience. The A3 offers optional power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the Sonata’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The A3 has a 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. Dual zone air conditioning is only available on the Sonata SEL Sport/N Line.

Both the A3 and the Sonata offer rear vents. For greater rear passenger comfort, the A3 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Sonata doesn’t offer rear air conditioning vents, only heat vents.

The A3’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling the transmission and speed with the brake pedal. With its available fully controlled system, the driver just activates it and it parks autonomously, starting, stopping and changing direction automatically. The Sonata doesn’t offer an automated parking system.

Consumer Reports® recommends both the Audi A3 and the Hyundai Sonata, based on reliability, safety and performance.
