Compare the2023 Infiniti QX55VS 2023 Cadillac XT4

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 Cadillac XT4 doesn’t offer pretensioners for its rear seat belts.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the QX55. But it costs extra on the XT4.

The QX55’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the XT4.

Both the QX55 and the XT4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, 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 XT4’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

The QX55’s 2.0 turbo 4-cylinder produces 33 more horsepower (268 vs. 235) and 22 lbs.-ft. more torque (280 vs. 258) than the XT4’s 2.0 turbo 4-cylinder.

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 XT4 doesn’t offer a CVT.

For better stopping power the QX55’s front brake rotors are larger than those on the XT4:

For better traction, the QX55 has larger tires than the XT4 (255/45R20 vs. 235/60R18). The QX55’s tires are larger than the largest tires available on the XT4 (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 XT4’s standard 60 series tires.

For better ride, handling and brake cooling the QX55 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the XT4.

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 XT4 doesn’t offer run-flat tires.

For better handling and stability, the track (width between the wheels) on the QX55 is 1.2 inches wider in the front and .7 inches wider in the rear than on the XT4.

For better maneuverability, the QX55’s turning circle is 1.6 feet tighter than the XT4’s (36.4 feet vs. 38 feet).

For greater off-road capability the QX55 has a 1.9 inches greater minimum ground clearance than the XT4 (8.6 vs. 6.7 inches), allowing the QX55 to travel over rougher terrain without being stopped or damaged.

The QX55 has .5 inches more front headroom, 1.1 inches more front hip room, .9 inches more front shoulder room, 4 inches more rear hip room and 2 inches more rear shoulder room than the XT4.

The QX55 has a much larger cargo volume with its rear seat up than the XT4 with its rear seat up (26.9 vs. 22.5 cubic feet). The QX55 has a much larger cargo volume with its rear seat folded than the XT4 with its rear seat folded (54.1 vs. 48.9 cubic feet).

Pulling a handle automatically lowers the QX55’s rear seats, to make changing between passengers and cargo easier. The XT4 doesn’t offer automatic folding seats.

The QX55’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The XT4’s rear power window switches have to be held the entire time to 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 XT4 can only close the windows from inside the vehicle, with the ignition on.

The QX55 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The XT4 doesn’t offer a locking fuel door.

The XT4 (except Luxury)’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The QX55 Essential/Sensory’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.
