Compare the2024 Toyota Grand HighlanderVS 2024 Subaru Ascent

The Grand Highlander has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Ascent 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 Grand Highlander 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. Only the Ascent Premium/Onyx/Limited/Touring offers a blind spot warning system.

To help make backing out of a parking space safer, the Grand Highlander has standard Rear Cross Traffic Alert and Parking Support Brake on the Limited/Platinum 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 Grand Highlander and the Ascent 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, 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 and around view monitors.

Toyota pays for scheduled maintenance on the Grand Highlander for 2 years and 25000 miles. Toyota will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Subaru doesn’t pay scheduled maintenance for the Ascent.

There are almost 2 times as many Toyota dealers as there are Subaru dealers, which makes it much easier should you ever need service under the Grand Highlander’s warranty.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Toyota vehicles are more reliable than Subaru vehicles. J.D. Power ranks Toyota above average in long-term dependability. With 34 more problems per 100 vehicles in the first three years of ownership, Subaru is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Toyota vehicles are more reliable than Subaru vehicles. Consumer Reports ranks Toyota second in overall reliability. Subaru is ranked 6th.

The Grand Highlander’s standard 2.4 turbo 4-cylinder produces 5 more horsepower (265 vs. 260) and 33 lbs.-ft. more torque (310 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder. The Grand Highlander Hybrid Max’s standard 2.4 turbo 4-cylinder hybrid produces 102 more horsepower (362 vs. 260) and 123 lbs.-ft. more torque (400 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder.

On the EPA test cycle the Grand Highlander gets better mileage than the Ascent:

Regenerative brakes improve the Grand Highlander Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The Ascent doesn’t offer a regenerative braking system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Toyota Grand Highlander higher (7 out of 10) than the Subaru Ascent (3). This means the Grand Highlander produces up to 24.5 pounds less smog-producing pollutants than the Ascent every 15,000 miles.

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

The Grand Highlander stops shorter than the Ascent:

For better traction, the Grand Highlander has larger tires than the Ascent (255/65R18 vs. 245/60R18).

For a smoother ride and more stable handling, the Grand Highlander’s wheelbase is 2.3 inches longer than on the Ascent (116.1 inches vs. 113.8 inches).

For better handling and stability, the track (width between the wheels) on the Grand Highlander is .9 inches wider in the front and 1.2 inches wider in the rear than on the Ascent.

The Grand Highlander’s front to rear weight distribution is more even (52% to 48%) than the Ascent’s (54.2% to 45.8%). This gives the Grand Highlander more stable handling and braking.

The Grand Highlander Platinum AWD handles at .80 G’s, while the Ascent Limited pulls only .79 G’s of cornering force in a Car and Driver skidpad test.

The Grand Highlander has .3 inches more front headroom, .2 inches more rear headroom, .9 inches more rear legroom, 1 inch more third row headroom, 1.8 inches more third row legroom and .3 inches more third row shoulder room than the Ascent.

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

To make loading groceries and cargo easier when your hands are full, the Grand Highlander Limited/Platinum’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.

The Grand Highlander’s standard towing capacity is much higher than the Ascent’s (5000 vs. 2000 pounds).

The Grand Highlander Platinum has a standard heads-up display that projects speed, tachometer 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 Grand Highlander and the Ascent have locks to prevent small children from operating them. When the lock on the Grand Highlander 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 Grand Highlander’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Ascent’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the Grand Highlander the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Toyota service department.) The driver of the Ascent can only operate the windows from inside the vehicle, with the ignition on.

The Grand Highlander’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.

When the Grand Highlander Limited/Platinum 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 Grand Highlander Limited/Platinum has standard front air conditioned seats and the Grand Highlander Platinum also has them in the second row. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Ascent doesn’t offer air-conditioned seats for the second row.

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

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