Compare the2025 Toyota 4RunnerVS 2025 Infiniti QX50

The 4Runner has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The QX50 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.

When descending a steep, off-road slope, the 4Runner TRD Off-Road/Trailhunter/TRD Pro’s standard Hill Descent Control allows you to creep down safely. The QX50 doesn’t offer Hill Descent Control.

Both the 4Runner and QX50 have Rear Cross Traffic Alert, but the 4Runner Limited/Platinum/Trailhunter/TRD Pro has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX50’s Rear Cross Traffic Alert doesn’t automatically brake.

The 4Runner’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The QX50 doesn’t offer a driver alert monitor.

Both the 4Runner and the QX50 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, available four-wheel drive and around view monitors.

There are over 6 times as many Toyota dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the 4Runner’s warranty.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the statistics that show that Toyota vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Toyota second in reliability, above the industry average. With 72 more problems per 100 vehicles, Infiniti is ranked 22nd.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Toyota vehicles are more reliable than Infiniti vehicles. Consumer Reports ranks Toyota second in overall reliability. Infiniti is ranked 13th.

The 4Runner’s standard 2.4 turbo 4-cylinder produces 10 more horsepower (278 vs. 268) and 37 lbs.-ft. more torque (317 vs. 280) than the QX50’s 2.0 turbo 4-cylinder. The 4Runner’s optional 2.4 turbo 4-cylinder hybrid produces 58 more horsepower (326 vs. 268) and 185 lbs.-ft. more torque (465 vs. 280) than the QX50’s 2.0 turbo 4-cylinder.

Regenerative brakes improve the 4Runner i-FORCE MAX’s fuel efficiency by converting inertia back into energy instead of wasting it. The QX50 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 4Runner Limited/i-FORCE MAX’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. The QX50 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Toyota 4Runner uses regular unleaded gasoline. The QX50 requires premium, which can cost on average about 84.9 cents more per gallon.

The 4Runner has 3 gallons more fuel capacity than the QX50 (19 vs. 16 gallons), for longer range between fill-ups.

For better stopping power the 4Runner’s brake rotors are larger than those on the QX50:

For better traction, the 4Runner has larger tires than the QX50 (265/70R17 vs. 235/55R19). The 4Runner SR5’s tires are larger than the largest tires available on the QX50 (265/70R17 vs. 255/45R20).

The Toyota 4Runner’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Infiniti QX50 only has 5 wheel lugs per wheel.

The 4Runner has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the QX50; 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.

The 4Runner Trailhunter/TRD Pro has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The QX50 doesn’t offer an active sway bar system.

The 4Runner offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The QX50’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the 4Runner’s wheelbase is 2 inches longer than on the QX50 (112.2 inches vs. 110.2 inches).

For better handling and stability, the average track (width between the wheels) on the 4Runner is 2.3 inches wider in the front and 2.8 inches wider in the rear than the average track on the QX50.

For greater off-road capability the 4Runner Trailhunter/TRD Pro has a 1.5 inches greater minimum ground clearance than the QX50 (10.1 vs. 8.6 inches), allowing the 4Runner to travel over rougher terrain without being stopped or damaged.

The 4Runner offers optional seating for 7 passengers; the QX50 can only carry 5.

The 4Runner has 2.2 inches more front legroom, .1 inches more front shoulder room, 2.3 inches more rear hip room and .7 inches more rear shoulder room than the QX50.

The 4Runner’s cargo area provides more volume than the QX50.

The 4Runner’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The QX50’s rear cargo window doesn’t open.

The 4Runner has a 6000 lbs. towing capacity. The QX50 has no towing capacity.

Standard Trailer Sway Control (TSC) on the 4Runner uses the Enhanced Vehicle Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The QX50 doesn’t offer electronic trailer sway control.

The engine in the 4Runner is mounted longitudinally (North-South), instead of sideways, as in the QX50. This makes it easier to service and maintain, because the accessory belts are in front.

The 4Runner’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The QX50 does not have an oil pressure gauge.

The 4Runner Platinum has a standard heads-up display that projects speed in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The QX50 doesn’t offer a heads-up display.

The power windows standard on both the 4Runner and the QX50 have locks to prevent small children from operating them. When the lock on the 4Runner is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX50 prevents the driver from operating the other windows just as it does the other passengers.

Both the 4Runner and the QX50 offer available heated front seats. The 4Runner Platinum also has standard heated second row seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.

The 4Runner TRD/Limited/Platinum/Trailhunter has a 115-volt a/c outlet in the cargo area, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The QX50 doesn’t offer a house-current electrical outlet.

The 4Runner is available in both rear-wheel drive and four-wheel drive configurations. The QX50 doesn’t offer a two-wheel drive configuration.

The Toyota 4Runner outsold the Infiniti QX50 by almost 12 to one during 2023.
