Compare the2024 Infiniti QX55VS 2025 Subaru Outback

The Infiniti QX55 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 Outback doesn’t offer a front passenger side knee airbag.

The QX55 Essential/Sensory has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Outback only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

The QX55 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 and moves the vehicle back into its lane. A system to reveal vehicles in the Outback’s blind spot costs extra.

To help make backing out of a parking space safer, the QX55 has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Subaru charges extra for Rear Cross Traffic Alert on the Outback and its not available on the Base.

Compared to metal, the QX55’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Subaru Outback has a metal gas tank.

Both the QX55 and the Outback 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Infiniti QX55 is safer than the Subaru Outback:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The QX55 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Outback’s 3-year/36,000-mile basic warranty expires 1 year or 24,000 miles sooner.

Infiniti’s powertrain warranty covers the QX55 1 year and 10,000 miles longer than Subaru covers the Outback. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Outback ends after only 5 years or 60,000 miles.

The QX55’s corrosion warranty is 2 years longer than the Outback’s (7 vs. 5 years).

Infiniti pays for scheduled maintenance on the QX55 for 3 years and 36,000 miles. Infiniti 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 Outback.

To reliably start during all conditions and help handle large electrical loads, the QX55 has a standard 720-amp battery. The Outback’s 620-amp battery isn’t as powerful.

The QX55’s 2.0 turbo 4-cylinder produces 86 more horsepower (268 vs. 182) and 104 lbs.-ft. more torque (280 vs. 176) than the Outback 2.5i’s standard 2.5 DOHC 4-cylinder. The QX55’s 2.0 turbo 4-cylinder produces 8 more horsepower (268 vs. 260) and 3 lbs.-ft. more torque (280 vs. 277) than the Outback XT/Wilderness’ standard 2.4 turbo 4-cylinder.

On the EPA test cycle the QX55 gets better fuel mileage than the Outback Wilderness (22 city/28 hwy vs. 21 city/26 hwy).

For better stopping power the QX55’s brake rotors are larger than those on the Outback:

For better traction, the QX55 has larger tires than the Outback (255/45R20 vs. 225/65R17).

The QX55’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Outback’s standard 65 series tires. The QX55’s tires are lower profile than the Outback Onyx/Limited/Touring’s 60 series tires.

For better ride, handling and brake cooling the QX55 has standard 20-inch wheels. Smaller 17-inch wheels are standard on the Outback. The Outback’s largest wheels are only 18-inches.

The QX55 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Outback doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX55 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Outback doesn’t offer run-flat tires.

The QX55 has engine 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 Outback doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the QX55’s wheelbase is 2.1 inches longer than on the Outback (110.2 inches vs. 108.1 inches).

For better handling and stability, the track (width between the wheels) on the QX55 is 2.5 inches wider in the front and .9 inches wider in the rear than the average track on the Outback.

The QX55 is 4.8 inches shorter than the Outback Wilderness, making the QX55 easier to handle, maneuver and park in tight spaces.

The QX55 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Outback doesn’t offer active noise cancellation.

The front step up height for the QX55 is 1.6 inches lower than the Outback (17.4” vs. 19”). The QX55’s rear step up height is .7 inches lower than the Outback’s (17.8” vs. 18.5”).

Pulling a handle automatically lowers the QX55’s rear seats, to make changing between passengers and cargo easier. The Outback doesn’t offer automatic folding seats.

The QX55 uses gas struts to support the hood for easier service access. The Outback 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.

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Subaru. J.D. Power ranks Infiniti 9th in service department satisfaction (above the industry average). With a 10% lower rating, Subaru is ranked 16th.

The QX55’s standard Entry/Exit Assist raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The Outback doesn’t offer an easy entry system.

The QX55’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 Outback’s standard rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the QX55 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Outback can only operate the windows from inside the vehicle, with the ignition on.

The QX55 has standard Infiniti Intelligent Key that allows you to unlock the doors from either front door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Access and Start costs extra on the Outback and isn’t available on the Outback Base.

The QX55’s standard 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 Outback’s manually variable intermittent wipers have to be constantly adjusted. The QX55 Essential/Sensory’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

The QX55’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the Outback Premium/Limited/Wilderness/Touring/Onyx.

The QX55 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 Outback Premium/Limited/Wilderness/Touring/Onyx.

Both the QX55 and the Outback offer rear vents. For greater rear passenger comfort, the QX55 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Outback 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 Infiniti QX55 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Outback and isn’t available on the Outback Base.
