Over 200 people are killed each year when backed over by motor vehicles. The XT6 Premium Luxury/Sport offers optional Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GX doesn’t offer backup collision prevention brakes.

A passive infrared night vision system optional on the XT6 Premium Luxury/Sport helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The GX doesn’t offer a night vision system.

For better protection of the passenger compartment, the XT6 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The GX uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the XT6 and the GX have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the XT6 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The GX has not been tested, yet.

There are over 2 times as many Cadillac dealers as there are Lexus dealers, which makes it much easier should you ever need service under the XT6’s warranty.

A hardened steel chain, with no maintenance needs, drives the camshafts in the XT6’s engine. A rubber cam drive belt that needs periodic replacement drives the GX’s camshafts. If the GX’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

As tested in Car and Driver the XT6 Premium Luxury/Sport 3.6 DOHC V6 is faster than the Lexus GX:

On the EPA test cycle the XT6 gets better mileage than the GX:

An engine control system that can shut down some of the engine’s cylinders helps improve the XT6’s fuel efficiency. The GX doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the XT6’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 GX doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Cadillac XT6 uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4-cylinder engine for maximum performance). The GX requires premium, which can cost on average about 82.8 cents more per gallon.

The XT6 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 GX doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac XT6 higher (6 to 7 out of 10) than the Lexus GX (3). This means the XT6 produces up to 24.5 pounds less smog-producing pollutants than the GX every 15,000 miles.

A nine-speed automatic is standard on the Cadillac XT6, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the GX.

The XT6 stops much shorter than the GX:

The XT6 Premium Luxury/Sport’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the GX’s optional 55 series tires.

For better ride, handling and brake cooling the XT6 Premium Luxury/Sport offers optional 21-inch wheels. The GX’s largest wheels are only 19-inches.

The XT6 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 GX doesn’t offer vehicle monitored tire inflation.

For superior ride and handling, the Cadillac XT6 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Lexus GX has a solid rear axle, with a non-independent rear suspension.

For a smoother ride and more stable handling, the XT6’s wheelbase is 2.9 inches longer than on the GX (112.7 inches vs. 109.8 inches).

The XT6 Sport AWD handles at .88 G’s, while the GX pulls only .74 G’s of cornering force in a Car and Driver skidpad test.

The XT6 Sport AWD executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the GX (27.2 seconds @ .67 average G’s vs. 28.3 seconds @ .58 average G’s).

For better maneuverability, the XT6’s turning circle is 2.4 feet tighter than the GX’s (38.7 feet vs. 41.1 feet).

The Cadillac XT6 may be more efficient, handle and accelerate better because it weighs about 500 to 750 pounds less than the Lexus GX.

Unibody construction lowers the XT6’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The GX doesn’t use unibody construction, but a body-on-frame design.

The front grille of the XT6 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GX doesn’t offer active grille shutters.

The XT6 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GX doesn’t offer active noise cancellation.

To make loading and unloading groceries and cargo easier, especially for short adults, the XT6 has a standard power liftgate, which opens and closes automatically by pressing a button, or on the XT6 Premium Luxury/Sport, by just kicking your foot under the back bumper, completely leaving your hands free. The GX doesn’t offer a power cargo door.

The XT6 Premium Luxury/Sport offers an optional heads-up display that projects speed, tachometer and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GX doesn’t offer a heads-up display.

The XT6’s power parking brake sets with one touch and releases with one touch or automatically. The GX’s parking brake has to be released manually.

The XT6’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The GX’s cruise control switches are unlit, making them difficult to find at night and operate safely.
