The XT6’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Nautilus doesn’t offer pre-crash pretensioners.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the XT6 are reminded to check the back seat if they opened the rear door before starting out. The Nautilus doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The XT6 offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Nautilus doesn’t offer backup collision prevention brakes.
A passive infrared night vision system optional on the XT6 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 Nautilus doesn’t offer a night vision system.
Both the XT6 and the Nautilus have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, 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.
The XT6’s corrosion warranty is 1 year longer than the Nautilus’ (6 vs. 5 years).
The XT6’s 3.6 DOHC V6 produces 60 more horsepower (310 vs. 250) than the Nautilus’ standard 2.0 turbo 4-cyl.
An engine control system that can shut down half of the engine’s cylinders helps improve the XT6’s fuel efficiency. The Nautilus doesn’t offer a system that can shut down part of the engine.
To lower fuel costs and make buying fuel easier, the Cadillac XT6 uses regular unleaded gasoline. The Nautilus requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.
The XT6 FWD’s standard fuel tank has a gallon more fuel capacity than the Nautilus (19 vs. 18 gallons), for longer range between fill-ups. The XT6 AWD’s standard fuel tank has 4 gallons more fuel capacity than the Nautilus (22 vs. 18 gallons).
A nine-speed automatic is standard on the Cadillac XT6, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Nautilus.
The XT6’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the Nautilus are solid, not vented.
The XT6’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Nautilus’ standard 60 series tires.
For better ride, handling and brake cooling the XT6 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Nautilus.
The Cadillac XT6’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Lincoln Nautilus only has 5 wheel lugs per wheel.
For better handling and stability, the track (width between the wheels) on the XT6 is 1.6 inches wider in the front and 1.5 inches wider in the rear than on the Nautilus.
The XT6 has standard seating for 7 passengers; the Nautilus can only carry 5.
The XT6’s cargo area provides more volume than the Nautilus.

43.1 cubic feet
Third Seat Removed
37.2 cubic feet
Second Seat Folded

68.8 cubic feet
Maximum trailer towing in the Lincoln Nautilus is limited to 3500 pounds. The XT6 offers up to a 4000 lbs. towing capacity.
J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Lincoln. J.D. Power ranks Cadillac third in service department satisfaction. With a 15% lower rating, Lincoln is ranked 7th.
The XT6 offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Nautilus doesn’t offer a heads-up display.
The power windows standard on both the XT6 and the Nautilus have locks to prevent small children from operating them. When the lock on the XT6 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Nautilus prevents the driver from operating the rear windows just as it does the other passengers.
The XT6’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 Nautilus’ standard manually variable intermittent wipers have to be constantly adjusted.
To improve rear visibility by keeping the rear window clear, the XT6 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Nautilus only has an intermittent setting, so in a hard rain visibility isn’t as good.
While driving with high beams on, sensitive light sensors standard on the XT6 detect other vehicles which could be blinded and automatically switch to low beams. The Nautilus doesn’t offer automatic dimming high beams.
When the XT6 is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Nautilus’ mirrors don’t automatically adjust for backing.
The XT6 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the Nautilus.
