The X3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The QX50 doesn’t offer pre-crash pretensioners.

The X3 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The QX50 doesn’t offer a whiplash protection system.

The X3 has a standard PostCrash iBrake, 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.

The X3’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 X3 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, plastic fuel tanks, 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 all wheel drive and around view monitors.

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

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the X3 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 96 vehicles tested by the IIHS. The QX50 has not been fully tested, yet.

Warranty

The X3’s corrosion warranty is 5 years longer than the QX50’s (12 vs. 7 years).

BMW pays for scheduled maintenance on the X3 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Infiniti doesn’t pay scheduled maintenance for the QX50.

There are over 73 percent more BMW dealers than there are Infiniti dealers, which makes it much easier should you ever need service under the X3’s warranty.

Reliability

J.D. Power and Associates rated the X3 first among compact premium suvs in their 2022 Initial Quality Study. The QX50 isn’t in the top three in its category.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks BMW above average in initial quality. With 39 more problems per 100 vehicles, Infiniti is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Infiniti vehicles. J.D. Power ranks BMW above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, Infiniti is rated below average.

Engine

The X3 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 114 more horsepower (382 vs. 268) and 89 lbs.-ft. more torque (369 vs. 280) than the QX50’s 2.0 turbo 4-cylinder.

Fuel Economy and Range

Regenerative brakes improve the X3’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 X3’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The QX50 doesn’t offer an automatic engine start/stop system.

The X3 has 1.2 gallons more fuel capacity than the QX50 (17.2 vs. 16 gallons), for longer range between fill-ups.

Transmission

The X3 M40i’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 QX50 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the X3 M40i’s brake rotors are larger than those on the QX50:

	X3 M40i	QX50
Front Rotors	13.7 inches	13 inches
Rear Rotors	13.5 inches	12.1 inches

The X3 stops much shorter than the QX50:

	X3	QX50
60 to 0 MPH	112 feet	126 feet	Motor Trend

Tires and Wheels

For better traction, the X3 has larger standard tires than the QX50 (245/50R19 vs. 235/55R19).

The X3’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the QX50’s standard 55 series tires. The X3’s optional 245/40R21 front and 275/35R21 rear tires have a lower 40 series front and 35 series rear profile than the QX50’s optional 45 series tires.

For better ride, handling and brake cooling the X3 offers optional 21-inch wheels. The QX50’s largest wheels are only 20-inches.

The X3 offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire 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.

Suspension and Handling

The X3 has standard front and rear gas-charged shocks for better control over choppy roads. The QX50’s suspension doesn’t offer gas-charged shocks.

The X3 offers an optional 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 X3’s wheelbase is 2.6 inches longer than on the QX50 (112.8 inches vs. 110.2 inches).

The X3’s front to rear weight distribution is more even (49% to 51%) than the QX50’s (57.7% to 42.3%). This gives the X3 more stable handling and braking.

The X3 M40i xDrive handles at .85 G’s, while the QX50 Essential AWD pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The X3 M40i xDrive executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the QX50 Essential AWD (25.9 seconds @ .72 average G’s vs. 26.9 seconds @ .64 average G’s).

Chassis

The front grille of the X3 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The QX50 doesn’t offer active grille shutters.

Passenger Space

The X3 has .1 inches more front headroom and .7 inches more front legroom than the QX50.

Towing

The X3’s standard towing capacity is much higher than the QX50’s (4400 vs. 0 pounds).

Servicing Ease

The engine in the X3 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.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Infiniti. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 4% lower rating, Infiniti is ranked 9th.

Ergonomics

The power windows standard on both the X3 and the QX50 have locks to prevent small children from operating them. When the lock on the X3 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.

The X3’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The QX50’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The X3’s headlights were rated “Good” by the IIHS, while the QX50’s headlights are rated “Acceptable” to “Marginal.”

The X3’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX50 Luxe/Essential/Sensory/Autograph.

The X3’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The QX50 has an automatic rear view mirror, but its side mirrors don’t dim.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW X3 offers an optional wireless phone charging system (Qi) in the center console. The QX50 doesn’t offer wireless personal charging.

The X3’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The QX50 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the X3 owner. The Complete Car Cost Guide estimates that insurance for the X3 will cost $455 less than the QX50 over a five-year period.

The X3 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the X3 will retain 49.78% to 50.55% of its original price after five years, while the QX50 only retains 43.84% to 45.08%.

Recommendations

Consumer Reports® recommends both the BMW X3 and the Infiniti QX50, based on reliability, safety and performance.

The BMW X3 outsold the Infiniti QX50 by over three to one during the 2021 model year.
