In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Ascent are reminded to check the back seat if they opened the rear door before starting out. The Model X doesn’t offer a back seat reminder.

The Ascent has standard Whiplash-Reducing Front Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Front Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Model X doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The Ascent (except Base) offers optional Reverse Automatic Braking that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Model X doesn’t offer backup collision prevention brakes.

When descending a steep, off-road slope, the Ascent’s standard Hill Descent Control allows you to creep down safely. The Model X doesn’t offer Hill Descent Control.

The Ascent (except Base/Premium) offers an optional Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Model X only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

To help make backing out of a parking space safer, the Ascent Premium/Onyx/Limited/Touring’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model X doesn’t offer a rear cross-path warning system.

The Ascent Premium/Onyx/Limited/Touring has standard STARLINK Connected Services, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model X doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Ascent and the Model X have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems and driver alert monitors.

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

The Subaru Ascent has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned an “Acceptable” 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 Model X has not yet been evaluated by the IIHS for 2024.

Warranty

There are over 3 times as many Subaru dealers as there are Tesla dealers, which makes it much easier should you ever need service under the Ascent’s warranty.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Ascent’s reliability 22 points higher than the Model X.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Subaru vehicles are better in initial quality than Tesla vehicles. J.D. Power ranks Subaru above average in initial quality. With 72 more problems per 100 vehicles, Tesla is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Subaru vehicles are more reliable than Tesla vehicles. Consumer Reports ranks Subaru 8 places higher in reliability than Tesla.

Engine

The flat cylinder configuration of the boxer engine in the Ascent lowers its center of gravity, enhancing handling stability without compromising ground clearance. The Model X doesn’t offer a boxer engine configuration.

Tires and Wheels

The Ascent has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Model X; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

For better maneuverability, the Ascent’s turning circle is 2.8 feet tighter than the Model X’s (38 feet vs. 40.8 feet).

For greater off-road capability the Ascent has a greater minimum ground clearance than the Model X (8.7 vs. 8.1 inches), allowing the Ascent to travel over rougher terrain without being stopped or damaged.

Chassis

The Subaru Ascent may be more efficient, handle and accelerate better because it weighs about 750 to 800 pounds less than the Tesla Model X.

Passenger Space

The Ascent has standard seating for 8 passengers; the Model X can only carry up to 7.

The Ascent has 1.1 inches more front legroom, 2.1 inches more front hip room, .4 inches more front shoulder room, 3.4 inches more rear shoulder room, 1.9 inches more third row legroom, 7.2 inches more third row hip room and 16.5 inches more third row shoulder room than the Model X.

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

Cargo Capacity

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

	Ascent	Model X
Behind Third Seat	17.8 cubic feet	15 cubic feet
Third Seat Folded	43.5 cubic feet	33.8 cubic feet

The Ascent’s available rear seats fold to accommodate long and bulky cargo. The Model X 6-Passenger doesn’t offer folding rear seats.

Servicing Ease

A maintenance reminder system is standard on the Ascent to save the owner time and money by calculating maintenance intervals for oil changes, tire rotation, and vehicle inspections, based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Tesla doesn’t offer a maintenance reminder on the Model X.

Ergonomics

The Ascent’s entire steering wheel hub sounds the horn, facilitating hitting the horn in an emergency. The Model X has a small, single button on the steering wheel spoke that can be hard to find quickly in an emergency.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Ascent’s available exterior PIN entry system (not available on Ascent Base). The Model X doesn’t offer an exterior PIN entry system.

The Ascent’s power window and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Model X’s cruise control switches are unlit, making them difficult to find at night and operate safely.

To improve rear visibility by keeping the rear window clear, the Ascent has a standard rear wiper. The Model X doesn’t offer a rear wiper.

The Ascent’s standard side window demisters help clear frost or condensation from the side windows in the winter. The Model X doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Ascent has standard extendable sun visors. The Model X doesn’t offer extendable visors.

The Ascent’s sun-visors swivel front-to-side to block glare from the side windows. The Model X’s visors are fixed into the windshield header.

Manual rear side window sunshades are available in the Ascent to help block heat and glare for the rear passengers. The Model X doesn’t offer rear side window sunshades.

The Ascent has a standard center folding armrest for the middle row passengers. A center armrest helps make middle row passengers more comfortable and it can provide a boundary between children. The Model X doesn’t offer a middle row seat center armrest.

The Ascent Touring has a 115-volt a/c outlet on the dashboard, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Model X doesn’t offer a house-current electrical outlet.

Economic Advantages

Insurance will cost less for the Ascent owner. The Complete Car Cost Guide estimates that insurance for the Ascent will cost $12800 to $14150 less than the Model X over a five-year period.

The Ascent will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Ascent will retain 54.18% to 55.67% of its original price after five years, while the Model X only retains 38.31% to 39.81%.

According to The Car Book by Jack Gillis, the Ascent is less expensive to operate than the Model X because typical repairs cost much less on the Ascent than the Model X, including $583 less for a water pump, $30 less for front brake pads and $971 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Subaru Ascent will be $56711 to $56926 less than for the Tesla Model X.

Recommendations

Consumer Reports® recommends the Subaru Ascent, based on reliability, safety and performance.
