As tested in Motor Trend the Infiniti QX55 is faster than the Cadillac XT4:

The QX55 has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the XT4. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

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:

The QX55 stops shorter than 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.

The QX55 Essential handles at .87 G’s, while the XT4 Sport AWD 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 XT4 Sport AWD (27 seconds @ .65 average G’s vs. 27.6 seconds @ .61 average G’s).

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.

For enhanced passenger comfort on long trips the QX55’s rear seats recline. The XT4’s rear seats don’t recline.

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 XT4’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.

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 XT4.
