Compare the2025 Hyundai SonataVS 2025 Subaru Legacy

The Sonata has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Legacy’s blind spot costs extra.

To help make backing out of a parking space safer, the Sonata has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. Subaru charges extra for Rear Cross Traffic Alert on the Legacy and its not available on the Base and the Legacy’s Rear Cross Traffic Alert does not include automatic braking.

Compared to metal, the Sonata’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Subaru Legacy has a metal gas tank.

Both the Sonata and the Legacy have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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, rearview cameras 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 Legacy:

The Hyundai Sonata achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Legacy last would have qualified as a “Top Safety Pick” in 2023.

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 Legacy’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

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

The Sonata’s corrosion warranty is 2 years longer than the Legacy’s (7 vs. 5 years).

Hyundai pays for scheduled maintenance on the Sonata for 3 years and 36,000 miles. Hyundai will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Subaru doesn’t pay scheduled maintenance for the Legacy.

There are over 31 percent more Hyundai dealers than there are Subaru dealers, which makes it easier should you ever need service under the Sonata’s warranty.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Hyundai vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Hyundai third in initial quality, above the industry average. With 21 more problems per 100 vehicles, Subaru is ranked 12th.

The Sonata’s standard 2.5 DOHC 4-cylinder produces 9 more horsepower (191 vs. 182) and 5 lbs.-ft. more torque (181 vs. 176) than the Legacy 2.5i’s standard 2.5 DOHC 4-cylinder. The Sonata N Line’s standard 2.5 turbo 4-cylinder produces 30 more horsepower (290 vs. 260) and 34 lbs.-ft. more torque (311 vs. 277) than the Legacy Sport/XT’s standard 2.4 turbo 4-cylinder.

As tested in Consumer Reports the Hyundai Sonata 4 cyl. is faster than the Legacy 2.5i 2.5 DOHC 4-cylinder:

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

To lower fuel costs and make buying fuel easier, the Hyundai Sonata uses regular unleaded gasoline. The Legacy Sport/XT requires premium for maximum efficiency, which can cost on average about 84.9 cents more per gallon.

The Sonata N Line’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Legacy doesn’t offer launch control.

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

The Sonata stops shorter than the Legacy:

For better traction, the Sonata N Line’s tires are larger than the largest tires available on the Legacy (245/40R19 vs. 225/55R17).

The Sonata N Line’s tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Legacy Sport/Limited/Touring’s 50 series tires.

For better ride, handling and brake cooling the Sonata N Line has standard 19-inch wheels. The Legacy’s largest wheels are only 18-inches.

The Sonata has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Legacy doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the Sonata’s wheelbase is 3.5 inches longer than on the Legacy (111.8 inches vs. 108.3 inches).

For better handling and stability, the average track (width between the wheels) on the Sonata is 1.6 inches wider in the front and .7 inches wider in the rear than the track on the Legacy.

For better maneuverability, the Sonata’s turning circle is .9 feet tighter than the Legacy’s (35.9 feet vs. 36.8 feet).

The Sonata has .6 inches more front headroom, 3.3 inches more front legroom and .6 inches more rear headroom than the Legacy.

The Sonata has a larger trunk than the Legacy (15.6 vs. 15.1 cubic feet).

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

The Sonata uses gas struts to support the hood for easier service access. The Legacy 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.

The power windows standard on both the Sonata and the Legacy have locks to prevent small children from operating them. When the lock on the Sonata is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Legacy prevents the driver from operating the other windows just as it does the other passengers.

On a hot day the Sonata’s driver can lower all the windows from a distance using the keyless remote. The driver of the Legacy can only operate the windows from inside the vehicle, with the ignition on.

The Sonata has a standard Proximity Key that allows you to unlock the doors from either front door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Keyless Entry and Start costs extra on the Legacy and isn’t available on the Legacy Base.

The Sonata’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 Legacy’s manually variable intermittent wipers have to be constantly adjusted.

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

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

J.D. Power and Associates rated the Sonata second among midsize cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Legacy isn’t in the top three.

The Hyundai Sonata outsold the Subaru Legacy by 78% during 2023.
