For enhanced safety, the front and middle seat shoulder belts of the Lincoln Navigator are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Aston Martin DBX doesn’t offer height-adjustable seat belts.
The middle row seatbelts optional on the Navigator Reserve/Black Label inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The DBX doesn’t offer inflatable seatbelts.
The Navigator’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 DBX doesn’t offer a driver alert monitor.
The Navigator has standard 911 Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The DBX doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Navigator and the DBX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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 Lincoln Navigator weighs 745 to 915 pounds more than the Aston Martin DBX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Navigator comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The DBX’s 3-year basic warranty expires 1 year sooner.
Lincoln’s powertrain warranty covers the Navigator 3 years longer than Aston Martin covers the DBX. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the DBX ends after only 3 years.
There are over 22 times as many Lincoln dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the Navigator’s warranty.
The Navigator 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 reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The DBX doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.
J.D. Power and Associates rated the Navigator second among large premium suvs in their 2019 Initial Quality Study. The DBX isn’t in the top three in its category.
To lower fuel costs and make buying fuel easier, the Lincoln Navigator uses regular unleaded gasoline (premium recommended for maximum performance). The DBX requires premium, which can cost 20 to 55 cents more per gallon.
The Navigator 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 DBX doesn’t offer a cap-less fueling system.
A ten-speed automatic is standard on the Lincoln Navigator, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the DBX.
The Lincoln Navigator’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Aston Martin DBX only has 5 wheel lugs per wheel.
The Navigator’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The DBX doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the Navigator’s wheelbase is 2 inches longer than on the DBX (122.5 inches vs. 120.5 inches).
The Navigator’s front to rear weight distribution is more even (49% to 51%) than the DBX’s (54% to 46%). This gives the Navigator more stable handling and braking.
For greater off-road capability the Navigator has a greater minimum ground clearance than the DBX (9.6 vs. 9.3 inches), allowing the Navigator to travel over rougher terrain without being stopped or damaged.
The front grille of the Navigator uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The DBX doesn’t offer active grille shutters.
The Navigator uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The DBX doesn’t offer active noise cancellation.
The Navigator offers optional seating for 8 passengers; the DBX can only carry 5.
The Navigator’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The DBX’s rear cargo window doesn’t open.
The Navigator’s standard towing capacity is much higher than the DBX’s (6200 vs. 5940 pounds). Maximum trailer towing in the Aston Martin DBX is only 5940 pounds. The Navigator offers up to a 8700 lbs. towing capacity.
The Navigator has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The DBX doesn’t offer a remote starting system.
The Navigator (except Standard) offers an available heads-up display that projects speed 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 DBX doesn’t offer a heads-up display.
In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Navigator’s exterior PIN entry system. The DBX doesn’t offer an exterior PIN entry system.
To improve rear visibility by keeping the rear window clear, the Navigator has a standard rear wiper. The DBX doesn’t offer a rear wiper.
To help drivers see further while navigating curves, the Navigator has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The DBX doesn’t offer cornering lights.
The Navigator 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 DBX.
The Navigator (except Standard) offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the DBX.
The Navigator is available in both rear-wheel drive and four-wheel drive configurations. The DBX doesn’t offer a two-wheel drive configuration.
A group of representative automotive journalists from North America selected the Navigator as the 2018 North American Truck of the Year. The DBX has never been chosen.
