The Enclave 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 Enclave 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 and moves the vehicle back into its lane. Only the Ascent Premium/Onyx/Limited/Touring offers a blind spot warning system.

To help make backing out of a parking space safer, the Enclave has standard Rear Cross Traffic Alert and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. Only the Ascent Premium/Onyx/Limited/Touring offers Rear Cross Traffic Alert and the Ascent’s Rear Cross Traffic Alert does not include automatic braking.

Both the Enclave and the Ascent have standard driver and passenger frontal airbags, front side-impact 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive, front parking sensors and driver alert monitors.

Warranty

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

There are over 65 percent more Buick dealers than there are Subaru dealers, which makes it much easier should you ever need service under the Enclave’s warranty.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the Enclave has a standard 220-amp alternator. The Ascent’s 190-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Buick vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Buick above average in initial quality. With 19 more problems per 100 vehicles, Subaru is rated lower.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the statistics that show that Buick vehicles are more reliable than Subaru vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 49 more problems per 100 vehicles, Subaru is ranked 13th.

Engine

The Enclave’s 2.5 turbo 4-cylinder produces 68 more horsepower (328 vs. 260) and 49 lbs.-ft. more torque (326 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder.

Fuel Economy and Range

In heavy traffic or at stoplights the Enclave’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.

To lower fuel costs and make buying fuel easier, the Buick Enclave uses regular unleaded gasoline. The Ascent requires premium for maximum efficiency, which can cost on average about 84.9 cents more per gallon.

The Enclave AWD’s standard fuel tank has 2.4 gallons more fuel capacity than the Ascent (21.7 vs. 19.3 gallons).

The Enclave 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.

Tires and Wheels

For better traction, the Enclave has larger standard tires than the Ascent (255/55R20 vs. 245/60R18). The Enclave’s optional tires are larger than the largest tires available on the Ascent (275/45R22 vs. 245/60R18).

The Enclave’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 Ascent’s standard 60 series tires. The Enclave’s optional tires have a lower 45 series profile than the Ascent Onyx/Limited/Touring’s 50 series tires.

For better ride, handling and brake cooling the Enclave has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Ascent. The Enclave’s optional 22-inch wheels are larger than the 20-inch wheels on the Ascent Onyx/Limited/Touring.

The Buick Enclave’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.

Suspension and Handling

The Enclave offers an available 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.

For a smoother ride and more stable handling, the Enclave’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 Enclave is 2.9 inches wider in the front and 2.9 inches wider in the rear than on the Ascent.

Chassis

The front grille of the Enclave 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.

The Enclave uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Ascent doesn’t offer active noise cancellation.

Passenger Space

The Enclave has 1.4 inches more front headroom, 2.1 inches more front legroom, .9 inches more front hip room, 1.1 inches more front shoulder room, 2.9 inches more rear legroom, 1.3 inches more rear hip room, 1.8 inches more rear shoulder room, 2.1 inches more third row headroom, .4 inches more third row legroom, 2.6 inches more third row hip room and .6 inches more third row shoulder room than the Ascent.

Cargo Capacity

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

	Enclave	Ascent
Behind Third Seat	22.9 cubic feet	17.8 cubic feet
Third Seat Folded	57.1 cubic feet	43.5 cubic feet
Second Seat Folded	97.5 cubic feet	75.6 cubic feet

A low lift-over cargo hatch design makes loading and unloading the Enclave easier. The Enclave’s cargo hatch lift-over height is 30.7 inches, while the Ascent’s liftover is 32 inches.

Pressing a switch automatically lowers the Enclave’s 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 Enclave’s liftgate can be opened just by waiting momentarily behind 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.

Servicing Ease

The Enclave 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.

J.D. Power and Associates surveys of service recipients show that Buick service is better than Subaru. J.D. Power ranks Buick third in service department satisfaction. With a 10% lower rating, Subaru is ranked 7th.

Ergonomics

The Enclave’s optional 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 Enclave’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 Enclave offers an optional heads-up display that projects speed, tachometer, navigation instruction, infotainment and driver assistance information 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 Enclave and the Ascent have locks to prevent small children from operating them. When the lock on the Enclave 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 Enclave’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 Enclave’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 Enclave’s standard Keyless Access allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Access and Start is an extra cost option on the Ascent and doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door. Keyless Access and Start is not available on the Ascent Base.

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

The Enclave 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 is only available on the Ascent Onyx/Limited/Touring.

The Enclave Avenir has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Ascent.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Buick Enclave has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Ascent.

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