For enhanced safety, the front and second-row seat shoulder belts of the Lincoln Aviator 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 its second-row seat belts.

Both the Aviator and XT6 have child safety locks to prevent children from opening the rear doors. The Aviator 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.

The Lincoln Aviator has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The XT6 doesn’t offer a front passenger side knee airbag.

The Aviator has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The XT6 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

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

Both the Aviator and XT6 have rear cross-traffic warning, but the Aviator has Cross-Traffic Alert with Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The XT6’s Rear Cross Traffic Alert doesn’t automatically brake.

The Aviator’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 Aviator and the XT6 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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 front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Aviator its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 127 vehicles tested by the IIHS. The XT6 is only a standard “Top Safety Pick” for 2019.

Warranty

There are over 21 percent more Lincoln dealers than there are Cadillac dealers, which makes it easier should you ever need service under the Aviator’s warranty.

Reliability

The Lincoln Aviator’s engine uses a cast iron block for durability, while the XT6’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The Aviator has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The XT6 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Lincoln vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Lincoln 7 places higher in reliability than Cadillac.

Engine

The Aviator’s 3.0 turbo V6 produces 165 more horsepower (400 vs. 235) and 157 lbs.-ft. more torque (415 vs. 258) than the XT6’s standard 2.0 turbo 4-cylinder. The Aviator’s 3.0 turbo V6 produces 90 more horsepower (400 vs. 310) and 144 lbs.-ft. more torque (415 vs. 271) than the XT6 Premium Luxury/Sport’s standard 3.6 DOHC V6.

As tested in Motor Trend the Lincoln Aviator is faster than the XT6 Premium Luxury/Sport 3.6 DOHC V6:

	Aviator	XT6
Zero to 60 MPH	5.4 sec	6.8 sec
Quarter Mile	14.1 sec	15.2 sec
Speed in 1/4 Mile	97.7 MPH	93.1 MPH

Fuel Economy and Range

The Aviator has 1.2 gallons more fuel capacity than the XT6 FWD’s standard fuel tank (20.2 vs. 19 gallons), for longer range between fill-ups.

Transmission

A 10-speed automatic is standard on the Lincoln Aviator, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the XT6.

Brakes and Stopping

For better stopping power the Aviator’s brake rotors are larger than those on the XT6:

	Aviator	XT6
Front Rotors	13.6 inches	12.6 inches
Rear Rotors	13.8 inches	12.4 inches

The Aviator stops shorter than the XT6:

	Aviator	XT6
60 to 0 MPH	124 feet	131 feet	Motor Trend

Tires and Wheels

For better traction, the Aviator has larger standard tires than the XT6 (255/60R19 vs. 235/55R20). The Aviator’s optional tires are larger than the largest tires available on the XT6 (275/40R22 vs. 265/45R21).

The Aviator’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the XT6’s standard 65 series tires. The Aviator’s optional tires have a lower 40 series profile than the XT6 Premium Luxury/Sport’s optional 45 series tires.

For better ride, handling and brake cooling the Aviator has standard 19-inch wheels. Smaller 18-inch wheels are standard on the XT6. The Aviator’s optional 22-inch wheels are larger than the 21-inch wheels optional on the XT6 Premium Luxury/Sport.

Suspension and Handling

The Aviator has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The XT6 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Aviator’s wheelbase is 6.4 inches longer than on the XT6 (119.1 inches vs. 112.7 inches).

For greater off-road capability the Aviator has a 2 inches greater minimum ground clearance than the XT6 (8.7 vs. 6.7 inches), allowing the Aviator to travel over rougher terrain without being stopped or damaged.

Passenger Space

The Aviator has 1.7 inches more front headroom, 1.8 inches more front legroom, 8.4 inches more front hip room, 3.2 inches more front shoulder room, .6 inches more rear headroom, 2.6 inches more rear hip room, 3.9 inches more rear shoulder room, 1.4 inches more third row hip room and .5 inches more third row shoulder room than the XT6.

Cargo Capacity

The Aviator’s cargo area provides more volume than the XT6.

	Aviator	XT6
Behind Third Seat	18.3 cubic feet	12.6 cubic feet

Towing

The Aviator’s standard towing capacity is much higher than the XT6’s (5600 vs. 1000 pounds).

Servicing Ease

The engine in the Aviator 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.

Ergonomics

The Aviator’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 Aviator the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the XT6 can only close the windows from inside the vehicle, with the ignition on.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Aviator’s exterior PIN entry system. The XT6 doesn’t offer an exterior PIN entry system, and its OnStar® can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

The Aviator’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 XT6’s standard manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Aviator’s available headlights were rated “Good” by the IIHS, while the XT6’s headlights are rated “Acceptable.”

The XT6’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Aviator (except Premiere)’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.

Manual rear side window sunshades are available in the Aviator to help block heat and glare for the rear passengers. The XT6 doesn’t offer rear side window sunshades.

Optional air conditioned front and second row seats keep the Aviator’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 Aviator (except Premiere) offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the XT6.

The Aviator has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The XT6 doesn’t offer a house-current electrical outlet.

Recommendations
