The Terrain SLT/AT4/Denali offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Outback 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.

Compared to metal, the Terrain’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Subaru Outback has a metal gas tank.

Both the Terrain and the Outback have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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 National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the GMC Terrain is safer than the Subaru Outback:

	Terrain	Outback
	Driver
STARS	5 Stars	5 Stars
Neck Injury Risk	17%	26%
Neck Stress	190 lbs.	281 lbs.
Neck Compression	10 lbs.	57 lbs.
	Passenger
STARS	5 Stars	4 Stars
Chest Compression	.6 inches	.6 inches
Neck Injury Risk	26%	43%

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 GMC Terrain is safer than the Subaru Outback:

	Terrain	Outback
	Rear Seat
STARS	5 Stars	5 Stars
Hip Force	630 lbs.	635 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	13 inches	14 inches
Spine Acceleration	40 G’s	43 G’s

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

Warranty

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

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

Reliability

To reliably start during all conditions and help handle large electrical loads, the Terrain has a standard 700-amp battery. The Outback’s 620-amp battery isn’t as powerful.

J.D. Power and Associates rated the Terrain second among compact suvs in their 2023 Initial Quality Study. The Outback isn’t in the top three in its category.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that GMC vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks GMC above average in initial quality. With 18 more problems per 100 vehicles, Subaru is rated lower.

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

Engine

The Terrain’s 1.5 turbo 4-cylinder produces 27 lbs.-ft. more torque (203 vs. 176) than the Outback 2.5i’s standard 2.5 DOHC 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the Terrain gets better mileage than the Outback:

			MPG
Terrain
	FWD	1.5 turbo 4-cyl.	24 city/29 hwy
	AWD	1.5 turbo 4-cyl.	23 city/28 hwy
Outback
	AWD	Wilderness 2.4 turbo flat-4	21 city/26 hwy

The Terrain 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 Outback doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the GMC Terrain higher (7 out of 10) than the Subaru Outback (6 to 7). This means the Terrain produces up to 1.1 pounds less smog-producing pollutants than the Outback every 15,000 miles.

Tires and Wheels

For better traction, the Terrain’s optional tires are larger than the largest tires available on the Outback (235/50R19 vs. 225/65R17).

The Terrain’s optional tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Outback Onyx/Limited/Touring’s 60 series tires.

For better ride, handling and brake cooling the Terrain offers optional 19-inch wheels. The Outback’s largest wheels are only 18-inches.

The Terrain 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 Outback doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The Terrain Denali AWD handles at .79 G’s, while the Outback Limited XT pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

The Terrain Denali AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the Outback Limited (27.5 seconds @ .64 average G’s vs. 28.4 seconds @ .62 average G’s).

Chassis

The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 200 to 250 pounds less than the Subaru Outback.

The Terrain is 9 inches shorter than the Outback Wilderness, making the Terrain easier to handle, maneuver and park in tight spaces.

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

Cargo Capacity

Pulling a handle automatically lowers the Terrain’s rear seats, to make changing between passengers and cargo easier. The Outback doesn’t offer automatic folding seats.

Towing

Standard Trailer Sway Control on the Terrain uses the StabiliTrak® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Outback doesn’t offer electronic trailer sway control.

Ergonomics

The Terrain offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Outback doesn’t offer a remote starting system.

The Terrain SLT/AT4/Denali’s standard easy entry system 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 Outback doesn’t offer an easy entry system.

The Terrain’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 Outback does not have an oil pressure gauge.

The Terrain (except SLE) offers an available 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 Outback doesn’t offer a heads-up display.

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

The Terrain’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 Outback’s standard power windows’ rear power window switches have to be held the entire time to open them fully.

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

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

Both the Terrain and the Outback offer rear vents. For greater rear passenger comfort, the Terrain has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Outback doesn’t offer rear air conditioning vents, only heat vents.

The Terrain offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Outback doesn’t offer a house-current electrical outlet.

The Terrain Denali’s optional Automatic Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Outback doesn’t offer an automated parking system.

Model Availability

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

Economic Advantages

According to The Car Book by Jack Gillis, the Terrain is less expensive to operate than the Outback because typical repairs cost less on the Terrain than the Outback, including $179 less for front struts.
