Compare the2026 Hyundai SonataVS 2026 Audi A5

Both the Sonata and the A5 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, driver alert monitors and available all wheel drive.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Hyundai Sonata is safer than the A5:

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 A5’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Hyundai’s powertrain warranty covers the Sonata 6 years and 50,000 miles longer than Audi covers the A5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the A5 ends after only 4 years or 50,000 miles.

There are almost 3 times as many Hyundai dealers as there are Audi dealers, which makes it much easier should you ever need service under the Sonata’s warranty.

J.D. Power and Associates rated the Sonata second among midsize cars in their 2025 Initial Quality Study. The A5 isn’t in the top three in its category.

J.D. Power and Associates’ 2025 Initial Quality Study of new car owners surveyed provide the statistics that show that Hyundai vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Hyundai third in initial quality, above the industry average. With 96 more problems per 100 vehicles, Audi is ranked 30th, below the industry average.

J.D. Power and Associates’ 2025 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Hyundai vehicles are more reliable than Audi With 51 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Hyundai higher than Audi.

From surveys of all its subscribers, Consumer Reports’ March 2026 Auto Issue reports that Hyundai vehicles are more reliable than Audi vehicles. Consumer Reports ranks Hyundai 1 place higher in reliability than Audi.

The Sonata N Line’s standard 2.5 turbo 4-cylinder produces 22 more horsepower (290 vs. 268) and 16 lbs.-ft. more torque (311 vs. 295) than the A5’s 2.0 turbo 4-cylinder hybrid.

On the EPA test cycle the Sonata gets better mileage than the A5:

To lower fuel costs and make buying fuel easier, the Hyundai Sonata uses regular unleaded gasoline. The A5 requires premium, which can cost on average about 84.9 cents more per gallon.

The Sonata has 1.1 gallons more fuel capacity than the A5 (15.9 vs. 14.8 gallons), for longer range between fill-ups.

An eight-speed automatic (SMG) is standard on the Hyundai Sonata, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A5.

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

The Sonata stops shorter than the A5:

The Sonata SEL Sport has a standard space-saver spare (not available on SE/N Line) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the A5; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

For better maneuverability, the Sonata’s turning circle is 3.8 feet tighter than the A5’s (35.9 feet vs. 39.7 feet).

The Hyundai Sonata may be more efficient, handle and accelerate better because it weighs about 550 to 850 pounds less than the Audi A5.

The design of the Hyundai Sonata amounts to more than styling. The Sonata has an aerodynamic coefficient of drag of .27 Cd. That is significantly lower than the A5 (.31) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Sonata get better fuel mileage.

The Sonata has 4.8 inches more front legroom, .6 inches more front shoulder room, .6 inches more rear headroom and 1 inch more rear shoulder room than the A5.

The Sonata is available in both front-wheel drive and all-wheel drive configurations. The A5 doesn’t offer a two-wheel drive configuration.
