Safety

Both the Aviator and GX460 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 GX460’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 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 GX460 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.

Over 200 people are killed each year when backed over by motor vehicles. The Aviator (except Base) offers an optional Reverse Brake Assist that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GX460 doesn’t offer backup collision prevention brakes.

For better protection of the passenger compartment, the Aviator 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 GX460 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Aviator and the GX460 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive and around view monitors.

Warranty

There are almost 4 times as many Lincoln dealers as there are Lexus dealers, which makes it much easier should you ever need service under the Aviator’s warranty.

Reliability

The Lincoln Aviator’s engines use a cast iron block for durability, while the GX460’s engine uses 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 GX460 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

To reliably power the ignition and other systems and to recharge the battery, the Aviator has a standard -amp alternator (250-amp - Aviator optional). The GX460’s 130-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Lincoln vehicles are better in initial quality than Lexus vehicles. J.D. Power ranks Lincoln fifth in initial quality, above the industry average. With 6 more problems per 100 vehicles, Lexus is ranked 8th.

Engine

The Aviator’s standard 3.0 turbo V6 produces 99 more horsepower (400 vs. 301) and 86 lbs.-ft. more torque (415 vs. 329) than the GX460’s 4.6 DOHC V8. The Aviator’s optional 3.0 turbo V6 hybrid produces 193 more horsepower (494 vs. 301) and 301 lbs.-ft. more torque (630 vs. 329) than the GX460’s 4.6 DOHC V8.

Fuel Economy and Range

On the EPA test cycle the Aviator gets better fuel mileage than the GX460:

Regenerative brakes improve the Aviator Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The GX460 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Aviator’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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The GX460 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Lincoln Aviator uses regular unleaded gasoline (premium recommended for maximum performance). The GX460 requires premium, which can cost 20 to 55 cents more per gallon.

The Aviator 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 GX460 doesn’t offer a cap-less fueling system.

Transmission

A 10-speed automatic is standard on the Lincoln Aviator, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the GX460.

Tires and Wheels

The Aviator’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 GX460’s standard 60 series tires. The Aviator Reserve/Grand Touring/Black Label’s tires have a lower 50 series profile than the GX460’s 60 series tires.

For better ride, handling and brake cooling the Aviator has standard 19-inch wheels. Only 18-inch wheels are available on the GX460. The Aviator offers optional 22-inch wheels.

Suspension and Handling

For superior ride and handling, the Lincoln Aviator 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 GX460 has a solid rear axle, with a non-independent rear suspension.

For a smoother ride and more stable handling, the Aviator’s wheelbase is 9.3 inches longer than on the GX460 (119.1 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the Aviator is 4.5 inches wider in the front and 4.5 inches wider in the rear than on the GX460.

For better maneuverability, the Aviator’s turning circle is 1.9 feet tighter than the GX460’s (39.2 feet vs. 41.1 feet).

Chassis

The Lincoln Aviator may be more efficient, handle and accelerate better because it weighs up to about 350 pounds less than the Lexus GX460.

Unibody construction lowers the Aviator’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 GX460 uses body-on-frame design instead.

The front grille of the Aviator uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GX460 doesn’t offer active grille shutters.

The Aviator Grand Touring/Black Label uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GX460 doesn’t offer active noise cancellation.

Passenger Space

The Aviator has 15 cubic feet more passenger volume than the GX460 (144.7 vs. 129.7).

The Aviator has 3.5 inches more front headroom, 1.3 inches more front legroom, 2 inches more front hip room, 6.1 inches more front shoulder room, 6 inches more rear legroom, 3.1 inches more rear hip room, 4 inches more rear shoulder room and 1.7 inches more third row headroom than the GX460.

Cargo Capacity

The Aviator’s cargo area provides more volume than the GX460.

Pressing a switch automatically lowers the Aviator’s second and third row seats, to make changing between passengers and cargo easier. The GX460 doesn’t offer automatic folding second row seats.

The Aviator’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The GX460’s swing out door blocks loading from the passenger’s side.

To make loading and unloading groceries and cargo easier when your hands are full, the Aviator’s power cargo door can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The GX460 doesn’t offer a power or hands-free opening cargo door.

Ergonomics

The Aviator (except Base) offers an available 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 GX460 doesn’t offer a heads-up display.

The Aviator’s power parking brake sets with one touch and releases with one touch or automatically. The GX460’s parking brake has to released manually.

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 GX460 doesn’t offer an exterior PIN entry system.

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 GX460 doesn’t offer an exterior PIN entry system.

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 GX460’s standard manually variable intermittent wipers have to be constantly adjusted.

The Aviator’s power mirror controls are mounted on the armrest for easy access. The GX460’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

Optional air conditioned the front and second row seats keep the Aviator’s passengers comfortable and take the sting out of hot leather in summer. The GX460 doesn’t offer air-conditioned seats for the second row.

The Aviator (except Base)’s optional Active Park Assist Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The GX460 doesn’t offer an automated parking system.

Model Availability

The Aviator is available in both rear-wheel drive and four-wheel drive configurations. The GX460 doesn’t offer a two-wheel drive configuration.
