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 Chevrolet Tahoe doesn’t offer pretensioners for its second-row seat belts.

Both the Aviator and Tahoe 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 Tahoe’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 Tahoe doesn’t offer knee airbags.

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 Tahoe 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.

The Aviator has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Tahoe’s blind spot costs extra.

To help make backing out of a parking space safer, the Aviator has standard Cross-Traffic Alert with Braking and automatically engage the brakes. Chevrolet charges extra for Rear Cross Traffic Alert on the Tahoe and the Tahoe’s Rear Cross Traffic Alert does not include automatic braking.

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 Tahoe doesn’t offer a driver alert monitor.

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 Tahoe uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Aviator and the Tahoe have standard driver and passenger frontal airbags, front side-impact 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, rearview cameras, available all wheel drive and around view monitors.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Lincoln Aviator is safer than the Chevrolet Tahoe:

	Aviator	Tahoe
	Rear Seat
STARS	5 Stars	5 Stars
HIC	86	88
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	14 inches
Hip Force	573 lbs.	764 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Aviator, with its four-star roll-over rating, is 6.1% to 7.2% less likely to roll over than the Tahoe, which received a three-star rating.

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 vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Aviator the rating of “Top Safety Pick” for 2022, a rating granted to only 163 vehicles tested by the IIHS. The Tahoe has not been tested, yet.

Warranty

The Aviator comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck. The Tahoe’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Lincoln’s powertrain warranty covers the Aviator 1 year and 10,000 miles longer than Chevrolet covers the Tahoe. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Tahoe ends after only 5 years or 60,000 miles.

The Aviator’s corrosion warranty is unlimited miles longer than the Tahoe’s (unlimited vs. 100,000 miles).

Reliability

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

For smoother operation, better efficiency and fewer moving parts, the Aviator has an overhead cam design, rather than the old pushrod design of some of the engines in the Tahoe.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Lincoln vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Lincoln 10 places higher in reliability than Chevrolet.

Engine

The Aviator’s 3.0 turbo V6 produces 45 more horsepower (400 vs. 355) and 32 lbs.-ft. more torque (415 vs. 383) than the Tahoe’s standard 5.3 V8.

As tested in Motor Trend the Lincoln Aviator is faster than the Chevrolet Tahoe 5.3 V8:

	Aviator	Tahoe
Zero to 60 MPH	5.4 sec	7.5 sec
Quarter Mile	14.1 sec	15.7 sec
Speed in 1/4 Mile	97.7 MPH	90.1 MPH

Fuel Economy and Range

On the EPA test cycle the Aviator gets better mileage than the Tahoe:

			MPG
Aviator
	RWD	3.0 turbo V6	18 city/26 hwy
	AWD	3.0 turbo V6	17 city/24 hwy
Tahoe
	RWD	5.3 OHV V8	15 city/20 hwy
		6.2 OHV V8	14 city/20 hwy
	AWD	5.3 OHV V8	15 city/20 hwy
		6.2 OHV V8	14 city/18 hwy

Brakes and Stopping

The Aviator stops much shorter than the Tahoe:

	Aviator	Tahoe
60 to 0 MPH	124 feet	134 feet	Motor Trend
60 to 0 MPH (Wet)	145 feet	153 feet	Consumer Reports

Tires and Wheels

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 Tahoe’s standard 65 series tires. The Aviator’s optional tires have a lower 40 series profile than the Tahoe’s optional 50 series tires.

For better ride, handling and brake cooling the Aviator has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Tahoe.

Suspension and Handling

The Aviator offers optional vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Tahoe doesn’t offer variable-assist power steering.

The Aviator AWD handles at .80 G’s, while the Tahoe LT 4x4 pulls only .68 G’s of cornering force in a Motor Trend skidpad test.

The Aviator AWD executes Motor Trend’s “Figure Eight” maneuver 2.3 seconds quicker than the Tahoe LT 4x4 (27.1 seconds @ .69 average G’s vs. 29.4 seconds @ .54 average G’s).

For greater off-road capability the Aviator has a greater minimum ground clearance than the Tahoe (8.7 vs. 8 inches), allowing the Aviator to travel over rougher terrain without being stopped or damaged.

Chassis

The Lincoln Aviator may be more efficient, handle and accelerate better because it weighs about 750 to 1050 pounds less than the Chevrolet Tahoe.

The Aviator is 11.4 inches shorter than the Tahoe, making the Aviator easier to handle, maneuver and park in tight spaces.

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 Tahoe doesn’t use unibody construction, but a body-on-frame design.

The Aviator (except Premiere) offers available computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Tahoe doesn’t offer active noise cancellation.

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 Tahoe’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 Tahoe 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 Tahoe 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.

To help drivers see further while navigating curves, the Aviator (except Premiere) offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Tahoe doesn’t offer cornering lights.

Manual rear side window sunshades are available in the Aviator to help block heat and glare for the rear passengers. The Tahoe 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 Tahoe 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 Tahoe.
