For enhanced safety, the front and second-row seat shoulder belts of the Infiniti QX80 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.

The Infiniti QX80 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.

With its standard ProPILOT Assist 1.1, the Infiniti QX80 is better at preventing collisions with pedestrians than the Chevrolet Tahoe, according to the Insurance Institute for Highway Safety:

The QX80’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.

Both the QX80 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, blind spot warning systems, around view monitors, rear cross-path warning and available all wheel drive.

The Insurance Institute for Highway Safety does 40 MPH moderate front offset crash tests on new cars. In this updated test, results indicate that the QX80 is much safer than the Tahoe:

The Infiniti QX80 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Tahoe is not even a standard “Top Safety Pick” for 2025.

Warranty

The QX80 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Tahoe’s 3-year/36,000-mile basic warranty expires 1 year or 24,000 miles sooner.

Infiniti’s powertrain warranty covers the QX80 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 QX80’s corrosion warranty is 1 year and unlimited miles longer than the Tahoe’s (7/unlimited vs. 6/100,000).

Infiniti pays for scheduled maintenance on the QX80 for 3 years and 45000 miles. Infiniti will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Chevrolet only pays for the first scheduled maintenance visit on the Tahoe.

Reliability

For smoother operation, better efficiency and fewer moving parts, the QX80 has an overhead cam design, rather than the old pushrod design of some of the engines in the Tahoe.

Engine

The QX80’s 3.5 turbo V6 produces 95 more horsepower (450 vs. 355) and 133 lbs.-ft. more torque (516 vs. 383) than the Tahoe’s standard 5.3 V8. The QX80’s 3.5 turbo V6 produces 30 more horsepower (450 vs. 420) and 56 lbs.-ft. more torque (516 vs. 460) than the Tahoe’s optional 6.2 V8.

As tested in Car and Driver the Infiniti QX80 is faster than the Chevrolet Tahoe 5.3 V8:

	QX80	Tahoe
Zero to 60 MPH	6.1 sec	7.5 sec
Zero to 100 MPH	15 sec	20.5 sec
5 to 60 MPH Rolling Start	7.2 sec	8.4 sec
Quarter Mile	14.5 sec	15.8 sec
Speed in 1/4 Mile	98 MPH	89 MPH
Top Speed	123 MPH	115 MPH

Fuel Economy and Range

On the EPA test cycle the QX80 gets better mileage than the Tahoe:

			MPG
QX80
	RWD	3.5 turbo V6	16 city/20 hwy
	AWD	3.5 turbo V6	16 city/19 hwy
Tahoe
	RWD	5.3 OHV V8	15 city/20 hwy
		6.2 OHV V8	15 city/20 hwy
	AWD	5.3 OHV V8	14 city/18 hwy
		5.3 OHV V8	15 city/19 hwy
		6.2 OHV V8	14 city/18 hwy

Brakes and Stopping

For better stopping power the QX80’s standard brake rotors are larger than those on the Tahoe:

	QX80	Tahoe
Front Rotors	13.8 inches	13.5 inches
Rear Rotors	13.8 inches	13.6 inches

The QX80 stops much shorter than the Tahoe:

	QX80	Tahoe
60 to 0 MPH	122 feet	134 feet	Motor Trend

Tires and Wheels

For better traction, the QX80 has larger tires than the Tahoe (275/60R20 vs. 265/65R18).

The QX80’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.

For better ride, handling and brake cooling the QX80 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Tahoe.

Suspension and Handling

The QX80 has standard front and rear stabilizer bars, which help keep the QX80 flat and controlled during cornering. The Tahoe’s suspension doesn’t offer a rear stabilizer bar.

The QX80 has 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 QX80 Autograph AWD handles at .78 G’s, while the Tahoe Z71 4x4 pulls only .63 G’s of cornering force in a Car and Driver skidpad test.

The QX80 Autograph AWD executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the Tahoe LT 4x4 (27.9 seconds @ .62 average G’s vs. 29.4 seconds @ .54 average G’s).

For greater off-road capability the QX80 Pure has a 1.6 inches greater minimum ground clearance than the Tahoe (9.6 vs. 8 inches), allowing the QX80 to travel over rougher terrain without being stopped or damaged.

Chassis

The QX80 uses 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.

As tested by Car and Driver while cruising at 70 MPH, the interior of the QX80 Autograph AWD is quieter than the Tahoe Z71 4x4 (65 vs. 66 dB).

Passenger Space

The QX80 has 2.3 inches more third row hip room and .4 inches more third row shoulder room than the Tahoe.

For enhanced passenger comfort on long trips the QX80’s middle and third row seats recline. The Tahoe’s third row seats don’t recline.

Cargo Capacity

The QX80 has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly. The Tahoe doesn’t offer seats that fold into the floor.

Towing

The QX80’s standard towing capacity is much higher than the Tahoe’s (8500 vs. 7700 pounds).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Chevrolet. J.D. Power ranks Infiniti 7th in service department satisfaction (above the industry average). With a 6% lower rating, Chevrolet is ranked 13th.

Ergonomics

Unlike the driver-only memory system in the Tahoe LT/RST/Z71/Premier/High Country, the QX80 Sensory/Autograph has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The QX80’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.

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 QX80’s headlights were rated “Good” by the IIHS, while the Tahoe’s headlights are rated “Poor.”

The Infiniti QX80 has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors costs extra on the Tahoe and aren't offered on the LS.

The QX80 has standard heated front, second and third row seats; a heated third is standard on the QX80 Autograph, which keep the driver and passengers extremely comfortable in the winter. Chevrolet doesn’t offer heated seats in the third row of the Tahoe.

Standard air conditioned seats in the front and second seat rows keep the QX80 Luxe/Sensory/Autograph’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 QX80 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 Tahoe.

The QX80 Sensory/Autograph has standard massaging front and rear seats (rear massaging seats on Autograph). Massaging seats aren’t available in the Tahoe.

The Infiniti QX80 has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located for the driver. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Chevrolet charges extra for Homelink® on the Tahoe.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Infiniti QX80 has a standard wireless phone charging system (Qi) in the center console. Only the Tahoe LT/RST/Z71/Premier/High Country offers wireless charging.
