Compare the2025 Infiniti QX55VS 2024 BMW X3

For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX55 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 BMW X3 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Infiniti QX55 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X3 doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the QX55 are reminded to check the back seat if they opened the rear door before starting out. The X3 doesn’t offer a back seat reminder.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the QX55. But it costs extra on the X3.

Both the QX55 and the X3 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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 and available around view monitors.

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 X3’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the QX55 2 years and 20,000 miles longer than BMW covers the X3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X3 ends after only 4 years or 50,000 miles.

The X3’s redline is at 7000 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The QX55 has a 6000 RPM redline.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Infiniti above average in initial quality. With 19 more problems per 100 vehicles, BMW is rated below average.

The QX55’s 2.0 turbo 4-cylinder produces 20 more horsepower (268 vs. 248) and 22 lbs.-ft. more torque (280 vs. 258) than the X3 s/xDrive30i’s standard 2.0 turbo 4-cylinder.

On the EPA test cycle the QX55 gets better mileage than the X3:

The QX55 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 X3 doesn’t offer a CVT.

The QX55 stops shorter than the X3:

For better traction, the QX55 has larger tires than the X3 (255/45R20 vs. 245/50R19). The QX55’s tires are larger than the largest tires available on the X3 (255/45R20 vs. 245/45R20).

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 X3’s standard 50 series tires.

For better ride, handling and brake cooling the QX55 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the X3.

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 X3 doesn’t offer vehicle monitored tire inflation.

The QX55 Essential handles at .87 G’s, while the X3 xDrive30i pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The QX55 Essential executes Motor Trend’s “Figure Eight” maneuver quicker than the X3 xDrive30i (27 seconds @ .65 average G’s vs. 27.6 seconds @ .63 average G’s).

For better maneuverability, the QX55’s turning circle is 3 feet tighter than the X3’s (36.4 feet vs. 39.4 feet).

For greater off-road capability the QX55 has a greater minimum ground clearance than the X3 (8.6 vs. 8 inches), allowing the QX55 to travel over rougher terrain without being stopped or damaged.

The QX55 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The X3 doesn’t offer active noise cancellation.

The QX55 has .3 inches more front shoulder room, 2.3 inches more rear legroom and 1.1 inches more rear shoulder room than the X3.

The front step up height for the QX55 is 1.1 inches lower than the X3 (17.4” vs. 18.5”). The QX55’s rear step up height is .7 inches lower than the X3’s (17.8” vs. 18.5”).

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than BMW. J.D. Power ranks Infiniti 7th in service department satisfaction (above the industry average). With a 5% lower rating, BMW is ranked 10th.

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 X3 doesn’t offer an easy entry system.

The QX55’s standard Infiniti Intelligent Key allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Comfort Go standard on the X3 only offers hands-free access for the ignition, none to unlock the vehicle.

To improve rear visibility by keeping the rear window clear, the QX55 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the X3 only has an intermittent setting, so in a hard rain visibility isn’t as good.

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 X3.
