In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident.

Both the XT4 and the QX55 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

There are over 4 times as many Cadillac dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the XT4’s warranty.

On the EPA test cycle the XT4 AWD gets better fuel mileage than the QX55 CVT (22 city/29 hwy vs. 22 city/28 hwy).

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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) 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 20 to 55 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 (7 out of 10) than the Infiniti QX55 (6). This means the XT4 produces up to 1.1 pounds less smog-producing pollutants than the QX55 every 15,000 miles.

The XT4 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 QX55 doesn’t offer vehicle monitored tire inflation.

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 Cadillac XT4 may be more efficient, handle and accelerate better because it weighs about 150 to 350 pounds less than the Infiniti QX55.

The XT4 is 5.2 inches shorter than the QX55, making the XT4 easier to handle, maneuver and park in tight spaces.

The front grille of the XT4 Premium Luxury/Sport 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’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 standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX55 Essential/Sensory.

The XT4 Premium Luxury/Sport’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 XT4 and the QX55 offer available heated front seats. The XT4 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX55.

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

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Cadillac XT4 offers an optional wireless phone charging system (Qi) in the center console. The QX55 doesn’t offer wireless personal charging.
