For enhanced safety, the front and middle seat shoulder belts of the Land Rover Discovery 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 XT6 doesn’t offer pretensioners for the middle seat belts.

Both the Discovery and XT6 have child safety locks to prevent children from opening the rear doors. The Discovery has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The XT6’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Discovery. But it costs extra on the XT6.

When descending a steep, off-road slope, the Discovery’s standard Hill Descent Control allows you to creep down safely. The XT6 doesn’t offer Hill Descent Control.

The Discovery’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The XT6 doesn’t offer a driver alert monitor.

Both the Discovery and the XT6 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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 and available around view monitors.

The Discovery’s 3.0 turbo V6 diesel produces 172 lbs.-ft. more torque (443 vs. 271) than the XT6’s 3.6 DOHC V6.

For better traction, the Discovery’s optional tires are larger than the largest tires available on the XT6 (285/40R22 vs. 265/45R21).

The Discovery’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the XT6 Sport’s optional 45 series tires.

For better ride, handling and brake cooling the Discovery offers optional 22-inch wheels. The XT6’s largest wheels are only 21-inches.

The Discovery offers an optional full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the XT6, it requires you to depend on a temporary spare that limits mileage and speed before replacement.

For a smoother ride and more stable handling, the Discovery’s wheelbase is 2.3 inches longer than on the XT6 (115 inches vs. 112.7 inches).

For greater off-road capability the Discovery has a 2.05 inches greater minimum ground clearance than the XT6 (8.7 vs. 6.65 inches), allowing the Discovery to travel over rougher terrain without being stopped or damaged. The Discovery Air Suspension’s minimum ground clearance is 4.45 inches higher than on the XT6 (11.1 vs. 6.65 inches).

The Discovery is 3.4 inches shorter than the XT6, making the Discovery easier to handle, maneuver and park in tight spaces.

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

Flexibility is maximized at the game, campground or a drive-in theatre in the Discovery when its optional tailgating rear seats are deployed, allowing people to sit facing out of the liftgate. (Do not use while vehicle is in motion.) The XT6 doesn’t offer tailgating seats.

The engine in the Discovery is mounted longitudinally (North-South), instead of sideways, as in the XT6. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Unlike the driver-only memory system in the XT6, the Discovery HSE/HSE Luxury has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster) and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Discovery’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 XT6’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the Discovery the driver can close them all from a distance using the remote. The driver of the XT6 can only close the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are optional on the Discovery to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The XT6 doesn’t offer heated windshield washer nozzles.

Consumer Reports rated the Discovery’s headlight performance “Very Good,” a higher rating than the XT6’s headlights that were rated “Poor.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Discovery offers available headlight washers to keep headlight output high. The XT6 doesn’t offer headlight washers.

The XT6’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Discovery HSE/HSE Luxury’s optional 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.

The Discovery offers optional heated front, second and third row seats that keep the driver and passengers extremely comfortable in the winter. Cadillac doesn’t offer heated seats in the third row of the XT6.

Optional air-conditioned the front and second row seats keep the Discovery’s passengers comfortable and take the sting out of hot leather in summer. The XT6 doesn’t offer air-conditioned seats for the second row.

The Land Rover Discovery outsold the Cadillac XT6 by over two to one during the 2019 model year.
