Power ranks Cadillac higher than Infiniti.

On the EPA test cycle the XT4 gets better mileage than the QX55:

An engine control system that can shut down some of the engine’s cylinders helps improve the XT4’s fuel efficiency. The QX55 doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the XT4’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 QX55 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Cadillac XT4 uses regular unleaded gasoline (premium recommended for maximum performance). The QX55 requires premium, which can cost on average about 84.9 cents more per gallon.

The XT4 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The QX55 doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac XT4 higher (6 out of 10) than the Infiniti QX55 (5). This means the XT4 produces up to 6.9 pounds less smog-producing pollutants than the QX55 every 15,000 miles.

The XT4 stops much shorter than the QX55:

The XT4 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 QX55; 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.

The XT4 offers an available 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 QX55’s suspension doesn’t offer adjustable shock absorbers.

The XT4 Sport AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the QX55 Essential (26.3 seconds @ .66 average G’s vs. 27 seconds @ .65 average G’s).

The Cadillac XT4 may be more efficient, handle and accelerate better because it weighs about 250 to 350 pounds less than the Infiniti QX55.

The XT4 is 5.4 inches shorter than the QX55, making the XT4 easier to handle, maneuver and park in tight spaces.

The front grille of the XT4 (except with towing package) uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The QX55 doesn’t offer active grille shutters.

The XT4 has 4.5 inches more front legroom, 1.4 inches more rear headroom and .8 inches more rear legroom than the QX55.

The XT4 has a 2000 lbs. towing capacity. The QX55 has no towing capacity.

Standard Trailer Sway Control on the XT4 uses the StabiliTrak® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The QX55 doesn’t offer electronic trailer sway control.

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Infiniti. J.D. Power ranks Cadillac fifth in service department satisfaction. With a 1% lower rating, Infiniti is ranked 6th.

The XT4’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The QX55 does not have an oil pressure gauge.

The power windows standard on both the XT4 and the QX55 have locks to prevent small children from operating them. When the lock on the XT4 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX55 prevents the driver from operating the other windows just as it does the other passengers.

The XT4’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 QX55’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The XT4’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 QX55 has an automatic rear view mirror, but its side mirrors don’t dim.

Both the Cadillac XT4 and Infiniti QX55 offer exterior mirrors that can be folded to provide convenience. The XT4 features standard power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the QX55’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The XT4 offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the QX55.

The XT4’s available Automatic Park Assist can parallel park by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The QX55’s automatic parking system requires operating the brakes and transmission to safely park.

The XT4 is available in both front-wheel drive and four-wheel drive configurations. The QX55 doesn’t offer a two-wheel drive configuration.

The XT4 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the XT4 will retain 52.41% to 53.95% of its original price after five years, while the QX55 only retains 46.84% to 46.91%.

The Cadillac XT4 outsold the Infiniti QX55 by over four to one during 2023.
