Compare the2024 Subaru LegacyVS 2023 Kia Stinger

For enhanced safety, the front and rear seat shoulder belts of the Subaru Legacy have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Kia Stinger doesn’t offer pretensioners for its rear seat belts.

Over 200 people are killed each year when backed over by motor vehicles. The Legacy Sport/Limited/Touring has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Stinger 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 Legacy. But it costs extra on the Stinger.

Both the Legacy and the Stinger have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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, available blind spot warning systems, rear parking sensors, rear cross-path warning and driver alert monitors.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Legacy the rating of “Top Safety Pick” for 2023, a rating granted to only 98 vehicles tested by the IIHS. The Stinger has not been fully tested, yet.

The Legacy’s 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Stinger runs out after 100,000 miles.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Subaru vehicles are more reliable than Kia vehicles. Consumer Reports ranks Subaru 4 places higher in reliability than Kia.

The flat cylinder configuration of the boxer engine in the Legacy lowers its center of gravity, enhancing handling stability (That’s why Porsche uses boxer engines.). The Stinger doesn’t offer a boxer engine configuration.

To lower fuel costs and make buying fuel easier, the Subaru Legacy uses regular unleaded gasoline. The Stinger requires premium, which can cost on average about 82.8 cents more per gallon.

The Legacy has 2.6 gallons more fuel capacity than the Stinger (18.5 vs. 15.9 gallons), for longer range between fill-ups.

The Legacy has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Stinger doesn’t offer a CVT.

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

The Subaru Legacy may be more efficient, handle and accelerate better because it weighs about 300 to 400 pounds less than the Kia Stinger.

The front grille of the Legacy 2.5i uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Stinger doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the Legacy Sport is quieter than the Stinger GT2:

	Legacy	Stinger

The Legacy Limited/Sport/Touring’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 Stinger’s rear power window switches have to be held the entire time to open or close them fully.
