The Tahoe (except LS with front bench seat) has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Ascent doesn’t offer front seat center airbags.

The Tahoe (except LS) offers an optional HD Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Ascent only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

Both the Tahoe and the Ascent have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, 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, blind spot warning systems and rear cross-path warning.

The Chevrolet Tahoe weighs 870 to 1474 pounds more than the Subaru Ascent. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Chevrolet Tahoe is safer than the Subaru Ascent:

	Tahoe	Ascent
	Driver
STARS	5 Stars	5 Stars
HIC	146	190
Leg Forces (l/r)	152/161 lbs.	159/292 lbs.

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

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 Chevrolet Tahoe is safer than the Subaru Ascent:

	Tahoe	Ascent
	Front Seat
STARS	5 Stars	5 Stars
HIC	25	37
Hip Force	118 lbs.	274 lbs.
	Rear Seat
STARS	5 Stars	5 Stars

Hip Force	248 lbs.	346 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	14 inches	18 inches
Spine Acceleration	38 G’s	52 G’s

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

Warranty

The Tahoe’s corrosion warranty is 1 year longer than the Ascent’s (6 vs. 5 years).

There are almost 5 times as many Chevrolet dealers as there are Subaru dealers, which makes it much easier should you ever need service under the Tahoe’s warranty.

Reliability

The Tahoe 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 Ascent 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 Tahoe has a standard 220-amp alternator (250-amp - Tahoe Diesel). The Ascent’s 190-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the Tahoe has a standard 730-amp battery (850 Diesel). The Ascent’s 530-amp battery isn’t as powerful.

J.D. Power and Associates rated the Tahoe first among large suvs in their 2022 Initial Quality Study. The Ascent isn’t in the top three in its category.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Chevrolet vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Chevrolet third in initial quality, above the industry average. With 44 more problems per 100 vehicles, Subaru is ranked 20th, below the industry average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Chevrolet vehicles are more reliable than Subaru vehicles. J.D. Power ranks Chevrolet above average in long-term dependability. With 21 more problems per 100 vehicles in the first three years of ownership, Subaru is rated below average.

Engine

The Tahoe’s standard 5.3 V8 produces 95 more horsepower (355 vs. 260) and 106 lbs.-ft. more torque (383 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder. The Tahoe’s optional 6.2 V8 produces 160 more horsepower (420 vs. 260) and 183 lbs.-ft. more torque (460 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder.

The Tahoe’s 3.0 turbo diesel produces 17 more horsepower (277 vs. 260) and 183 lbs.-ft. more torque (460 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder.

As tested in Consumer Reports the Chevrolet Tahoe 5.3 V8 is faster than the Subaru Ascent:

	Tahoe	Ascent
Zero to 30 MPH	2.9 sec	3.3 sec
Zero to 60 MPH	7.8 sec	8 sec
Quarter Mile	16 sec	16.4 sec
Speed in 1/4 Mile	91 MPH	88 MPH

Fuel Economy and Range

An engine control system that can shut down some of the engine’s cylinders helps improve the Tahoe V8’s fuel efficiency. The Ascent doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the Tahoe’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Ascent doesn’t offer an automatic engine start/stop system.

The Tahoe has 4.7 gallons more fuel capacity than the Ascent (24 vs. 19.3 gallons), for longer range between fill-ups.

The Tahoe 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 Ascent doesn’t offer a cap-less fueling system.

Brakes and Stopping

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

	Tahoe	Ascent
Front Rotors	13.5 inches	13.1 inches
Rear Rotors	13.6 inches	13 inches

Tires and Wheels

For better traction, the Tahoe has larger standard tires than the Ascent (265/65R18 vs. 245/60R18). The Tahoe’s optional tires are larger than the largest tires available on the Ascent (275/50R22 vs. 245/60R18).

For better ride, handling and brake cooling the Tahoe offers optional 22-inch wheels. The Ascent’s largest wheels are only 20-inches.

The Chevrolet Tahoe’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Subaru Ascent only has 5 wheel lugs per wheel.

The Tahoe has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Ascent doesn’t offer vehicle monitored tire inflation.

The Tahoe has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Ascent; it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

Suspension and Handling

The Tahoe offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Ascent’s suspension doesn’t offer adjustable shock absorbers.

The Tahoe Z71/High Country has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Tahoe’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Ascent doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Tahoe’s wheelbase is 7.1 inches longer than on the Ascent (120.9 inches vs. 113.8 inches).

For better handling and stability, the track (width between the wheels) on the Tahoe is 4.1 inches wider in the front and 4.1 inches wider in the rear than on the Ascent.

The Tahoe’s front to rear weight distribution is more even (51% to 49%) than the Ascent’s (54.2% to 45.8%). This gives the Tahoe more stable handling and braking.

For greater off-road capability the Tahoe Z71 Air Ride has a 1.3 inches greater minimum ground clearance than the Ascent (10 vs. 8.7 inches), allowing the Tahoe to travel over rougher terrain without being stopped or damaged.

Chassis

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

As tested by Car and Driver while cruising at 70 MPH, the interior of the Tahoe Z71 4x4 is quieter than the Ascent Touring (66 vs. 67 dB).

Passenger Space

The Tahoe offers optional seating for 9 passengers; the Ascent can only carry 8.

The Tahoe has 14.8 cubic feet more passenger volume than the Ascent (168.3 vs. 153.5).

The Tahoe has 1 inch more front headroom, 2.3 inches more front legroom, 3.8 inches more front hip room, 4.9 inches more front shoulder room, 3.4 inches more rear legroom, 3.8 inches more rear hip room, 4.5 inches more rear shoulder room, 1.9 inches more third row headroom, 3.2 inches more third row legroom, 3.5 inches more third row hip room and 5.5 inches more third row shoulder room than the Ascent.

Cargo Capacity

The Tahoe’s cargo area provides more volume than the Ascent.

	Tahoe	Ascent
Behind Third Seat	25.5 cubic feet	17.8 cubic feet
Third Seat Folded	72.6 cubic feet	47.5 cubic feet
Second Seat Folded	122.9 cubic feet	86.5 cubic feet

The Tahoe’s cargo area is larger than the Ascent’s in almost every dimension:

	Tahoe	Ascent
Length to seat (3rd/2nd/1st)	24”/54”/89.5”	19.9”/47.6”/82.5”
Max Width	49.5”	50.5”
Min Width	49.4”	45.9”
Height	36.5”	33.9”

Pressing a switch automatically lowers the Tahoe’s (not available on LS) optional second row seats and pressing a switch automatically lowers or raises the third row seats, to make changing between passengers and cargo easier. The Ascent doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the Tahoe’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Ascent doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

The Tahoe’s minimum standard towing capacity is much higher than the Ascent’s (7700 vs. 2000 pounds). Maximum trailer towing in the Subaru Ascent is only 5000 pounds. The Tahoe offers up to a 8400 lbs. towing capacity.

The Tahoe 4WD with optional equipment can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Tahoe can be unhitched and driven around locally. The Ascent can’t be towed flat on the ground.

Servicing Ease

The Tahoe uses gas struts to support the hood for easier service access. The Ascent uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

Ergonomics

The Tahoe LT/RST/Z71/Premier/High Country’s standard easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Ascent doesn’t offer an easy entry system.

The Tahoe’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Ascent does not have an oil pressure gauge.

The Tahoe (except LS/LT/RST/Z71) offers an available heads-up display that projects speed, warning 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 Ascent doesn’t offer a heads-up display.

The power windows standard on both the Tahoe and the Ascent have locks to prevent small children from operating them. When the lock on the Tahoe is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Ascent prevents the driver from operating the other windows just as it does the other passengers.

The Tahoe’s front and rear power windows all lower 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 Ascent’s rear power window switches have to be held the entire time to open them fully.

On a hot day the Tahoe’s driver can lower all the windows from a distance using the keyless remote. The driver of the Ascent can only operate the windows from inside the vehicle, with the ignition on.

The Tahoe’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 Ascent’s standard manually variable intermittent wipers have to be constantly adjusted.

Consumer Reports rated the Tahoe’s headlight performance “Very Good,” a higher rating than the Ascent’s headlights, which were rated “Good.”

The Tahoe’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the Ascent Premium/Limited/Touring.

When the Tahoe LT/RST/Z71/Premier/High Country 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 Ascent’s mirrors don’t automatically adjust for backing.

The Tahoe Premier/High Country’s optional Enhanced Automatic Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Ascent doesn’t offer an automated parking system.

Model Availability

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

Economic Advantages

According to The Car Book by Jack Gillis, the Tahoe is less expensive to operate than the Ascent because typical repairs cost much less on the Tahoe than the Ascent, including $251 less for a starter and $345 less for front struts.

Recommendations

J.D. Power and Associates rated the Tahoe second among large suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Ascent isn’t in the top three.

The Chevrolet Tahoe outsold the Subaru Ascent by 71% during the 2021 model year.
