Compare the2023 Infiniti QX55VS 2023 BMW X4

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 X4 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 X4 doesn’t offer height-adjustable seat belts.

Both the QX55 and the X4 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, all wheel drive, 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 X4’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 X4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X4 ends after only 4 years or 50,000 miles.

The X4’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.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Infiniti vehicles are more reliable than BMW vehicles. Consumer Reports ranks Infiniti 1 place higher in reliability than BMW.

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 X4 xDrive30i’s standard 2.0 turbo 4-cylinder.

On the EPA test cycle the QX55 gets better mileage than the X4:

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 X4 doesn’t offer a CVT.

For better traction, the QX55 has larger tires than the X4 (255/45R20 vs. 245/50R19). The QX55’s tires are larger than the largest tires available on the X4 (255/45R20 vs. 245/44R20).

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 X4’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 X4.

For better maneuverability, the QX55’s turning circle is 3.4 feet tighter than the X4’s (36.4 feet vs. 39.8 feet).

For greater off-road capability the QX55 has a greater minimum ground clearance than the X4 (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 X4 doesn’t offer active noise cancellation.

The QX55 has 2.4 cubic feet more passenger volume than the X4 (100.2 vs. 97.8).

The QX55 has .4 inches more front shoulder room, 3.2 inches more rear legroom and 1.1 inches more rear shoulder room than the X4.

The QX55 has a much larger cargo volume with its rear seat up than the X4 with its rear seat up (26.9 vs. 18.5 cubic feet). The QX55 has a much larger cargo volume with its rear seat folded than the X4 with its rear seat folded (54.1 vs. 50.5 cubic feet).

The QX55 Essential/Sensory’s standard easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The X4 doesn’t offer an easy entry system.

To improve rear visibility by keeping the rear window clear, the QX55 has a standard rear wiper. The X4 doesn’t offer a rear wiper.
