The A5’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 A5 and Sonata have child safety locks to prevent children from opening the rear doors. The A5 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 A5 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.

The A5 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Sonata doesn’t offer front seat center airbags.

The A5 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 A5 has standard Maneuver Assist 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 A5. But it costs extra on the Sonata.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The A5 has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Sonata doesn’t offer a system that can receive automated systems from infrastructure.

The A5 offers an optional 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 A5 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, rear cross-path warning and driver alert monitors.

The Audi A5 weighs 556 to 858 pounds more than the Hyundai Sonata. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

The A5’s corrosion warranty is 5 years longer than the Sonata’s (12 vs. 7 years).

Reliability

The Audi A5’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.

From surveys of all its subscribers, Consumer Reports’ March 2025 Auto Issue reports that Audi vehicles are more reliable than Hyundai vehicles. Consumer Reports ranks Audi 3 places higher in reliability than Hyundai.

Engine

The A5’s 2.0 turbo 4-cylinder hybrid produces 77 more horsepower (268 vs. 191) and 114 lbs.-ft. more torque (295 vs. 181) than the Sonata’s standard 2.5 DOHC 4-cylinder.

As tested in Motor Trend the Audi A5 is faster than the Hyundai Sonata 4 cyl.:

	A5	Sonata
Zero to 60 MPH	5.6 sec	7.9 sec
Quarter Mile	14.1 sec	16 sec
Speed in 1/4 Mile	98.3 MPH	87.2 MPH

Fuel Economy and Range

Regenerative brakes improve the A5’s fuel efficiency by converting inertia back into energy instead of wasting it. The Sonata doesn’t offer a regenerative braking system.

Brakes and Stopping

For better stopping power the A5’s standard brake rotors are larger than those on the Sonata:

	A5	Sonata
Front Rotors	13.3 inches	12 inches
Rear Rotors	13 inches	11.2 inches

The A5’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Sonata are solid, not vented.

Tires and Wheels

For better traction, the A5 has larger standard tires than the Sonata (235/45R18 vs. 205/65R16).

The A5’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 A5 has standard 18-inch wheels. Smaller 16-inch wheels are standard on the Sonata SE.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the A5 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Sonata doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the A5’s wheelbase is 2 inches longer than on the Sonata (113.8 inches vs. 111.8 inches).

The A5’s front to rear weight distribution is more even (56% to 44%) than the Sonata’s (60% to 40%). This gives the A5 more stable handling and braking.

The A5 handles at .84 G’s, while the Sonata SEL Sport AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The A5 executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the Sonata SEL Sport AWD (26.4 seconds @ .69 average G’s vs. 27.7 seconds @ .61 average G’s).

Chassis

The A5 is 3.2 inches shorter than the Sonata, making the A5 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the A5. The Sonata doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier, especially for short adults, the A5 has a standard power liftgate, which opens and closes automatically by pressing a button or just by 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.

Servicing Ease

The engine in the A5 is mounted longitudinally (North-South), instead of sideways, as in the Sonata. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

When two different drivers share the A5, the memory seats and mirrors make it convenient for both. 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 A5’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The Sonata doesn’t offer an easy entry system.

The A5 Premium Plus/Prestige has a standard heads-up display that projects speed, navigation instruction, infotainment and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Sonata doesn’t offer a heads-up display.

The A5’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 A5 the driver can close them all 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 A5’s standard Audi Advanced Key allows you to unlock the doors from any outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Proximity Key standard on the Sonata doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The A5’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.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A5 Prestige has standard headlight washers to keep headlight output high. The Sonata doesn’t offer headlight washers.

Manual rear side window sunshades are available in the A5 to help block heat and glare for the rear passengers. The Sonata doesn’t offer rear side window sunshades.

The A5’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 A5 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 A5’s standard 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 A5 and Hyundai Sonata offer exterior mirrors that can be folded to provide convenience. The A5 features standard 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 A5 has standard heated front seats. Heated front seats are only available on the Sonata SEL Sport/N Line. The A5 Prestige also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Sonata.

Optional air-conditioned seats in the A5 (except Premium) keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Sonata doesn’t offer air-conditioned seats.

On extremely cold winter days, the A5’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Sonata doesn’t offer a heated steering wheel.

The A5 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 A5 and the Sonata offer rear vents. For greater rear passenger comfort, the A5 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.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi A5 has a standard wireless phone charging system (Qi) in the center console. Only the Sonata SEL Sport/N Line offers wireless charging.

The A5 Premium Plus/Prestige’s Park Assist Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Sonata doesn’t offer an automated parking system.
