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 Terrain are reminded to check the back seat if they opened the rear door before starting out. The Outlander Sport doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The Terrain has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Outlander Sport doesn’t offer backup collision prevention brakes.

When descending a steep, off-road slope, the Terrain AWD’s standard Hill Descent Control allows you to creep down safely. The Outlander Sport doesn’t offer Hill Descent Control.

The Terrain offers an optional HD Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Outlander Sport 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.

The Terrain 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 Outlander Sport SE/SEL offers a blind spot warning system.

To help make backing out of a parking space safer, the Terrain has standard Rear Cross Traffic Alert and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. Only the Outlander Sport SE/SEL offers Rear Cross Traffic Alert and the Outlander Sport’s Rear Cross Traffic Alert does not include automatic braking.

The Terrain has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, 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 Outlander Sport 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 Terrain and the Outlander Sport 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 and rearview cameras.

Warranty

There are over 5 times as many GMC dealers as there are Mitsubishi 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 760-amp battery. The Outlander Sport’s 530-amp battery isn’t as powerful.

Engine

The Terrain FWD’s standard 1.5 turbo 4-cylinder produces 27 more horsepower (175 vs. 148) and 39 lbs.-ft. more torque (184 vs. 145) than the Outlander Sport’s standard 2.0 DOHC 4-cylinder. The Terrain FWD’s 1.5 turbo 4-cylinder produces 7 more horsepower (175 vs. 168) and 17 lbs.-ft. more torque (184 vs. 167) than the Outlander Sport SEL’s standard 2.4 DOHC 4-cylinder. The Terrain AWD’s standard 1.5 turbo 4-cylinder produces 7 more horsepower (175 vs. 168) and 36 lbs.-ft. more torque (203 vs. 167) than the Outlander Sport SEL’s standard 2.4 DOHC 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the Terrain gets better mileage than the Outlander Sport:

			MPG
Terrain
	FWD	1.5 turbo 4-cyl.	26 city/28 hwy
	AWD	1.5 turbo 4-cyl.	24 city/28 hwy
Outlander Sport
	AWD	2.4 DOHC 4-cyl.	23 city/28 hwy

In heavy traffic or at stoplights the Terrain’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 Outlander Sport doesn’t offer an automatic engine start/stop system.

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 Outlander Sport doesn’t offer a cap-less fueling system.

Brakes and Stopping

For better stopping power the Terrain’s front brake rotors are larger than those on the Outlander Sport:

	Terrain	Outlander Sport
Front Rotors	11.8 inches	11.6 inches

Tires and Wheels

For better traction, the Terrain has larger tires than the Outlander Sport (235/65R17 vs. 215/70R16). The Terrain’s tires are larger than the largest tires available on the Outlander Sport (235/65R17 vs. 225/55R18).

The Terrain’s standard tires provide better handling because they have a lower 65 series profile (height to width ratio) that provides a stiffer sidewall than the Outlander Sport S’ standard 70 series tires.

For better ride, handling and brake cooling the Terrain has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Outlander Sport S. The Terrain’s optional 19-inch wheels are larger than the 18-inch wheels on the Outlander Sport ES/LE/SE/SEL.

Suspension and Handling

For a smoother ride and more stable handling, the Terrain’s wheelbase is 2.4 inches longer than on the Outlander Sport (107.5 inches vs. 105.1 inches).

For better handling and stability, the track (width between the wheels) on the Terrain is 3.4 inches wider in the front and 3.5 inches wider in the rear than on the Outlander Sport.

Chassis

The front grille of the Terrain uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Outlander Sport doesn’t offer active grille shutters.

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

Passenger Space

The Terrain has .6 inches more front headroom, 3.2 inches more front hip room, 1.5 inches more front shoulder room, 1.3 inches more rear headroom, 2.9 inches more rear legroom and .2 inches more rear shoulder room than the Outlander Sport.

Cargo Capacity

The Terrain has a much larger cargo volume with its rear seat up than the Outlander Sport with its rear seat up (29.8 vs. 21.7 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the Outlander Sport with its rear seat folded (63.5 vs. 49.5 cubic feet).

To make loading and unloading groceries and cargo easier when your hands are full, the Terrain’s power liftgate can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Terrain’s power liftgate can also be opened or closed by pressing a button. The Outlander Sport doesn’t offer a power or hands-free opening liftgate.

Payload and Towing

The Terrain has a 800 lbs. towing capacity. The Outlander Sport has no towing capacity.

The Terrain has a much higher standard payload capacity than the Outlander Sport (1184 vs. 827 lbs.).

The Terrain has a much higher maximum payload capacity than the Outlander Sport (1252 vs. 827 lbs.).

Ergonomics

When two different drivers share the Terrain, the optional memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Outlander Sport doesn’t offer a memory system.

The Terrain’s optional 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 Outlander Sport 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 Outlander Sport does not have an oil pressure gauge.

The Terrain’s power parking brake sets with one touch and releases with one touch or automatically. The Outlander Sport has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The power windows standard on both the Terrain and the Outlander Sport 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 Outlander Sport prevents the driver from operating the other 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 Outlander Sport’s passenger windows don’t open automatically.

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

The Outlander Sport’s standard power locks don’t automatically lock the doors. The Terrain’s standard doors lock when the transmission is engaged. This is an important feature for occupant safety. Locked doors are proven to open less often in collisions, and they are also effective in preventing crime at traffic lights.

The Terrain’s standard Keyless Open and Start allow you to unlock the doors from any outside door handle, unlock the cargo door, and start the engine, all without removing the key from the pocket or purse. FAST-Key is only offered on the Outlander Sport SE/SEL, and doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

To improve rear visibility by keeping the rear window clear, the Terrain has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Outlander Sport only has an intermittent setting, so in a hard rain visibility isn’t as good.

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

When the Terrain with available tilt-down mirrors 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 Outlander Sport’s mirrors don’t automatically adjust for backing.

The Terrain has standard heated front seats. Heated front seats are only available on the Outlander Sport LE/SE/SEL. The Terrain also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Outlander Sport.

Optional air-conditioned seats in the Terrain keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Outlander Sport doesn’t offer air-conditioned seats.

On extremely cold winter days, the Terrain’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Outlander Sport doesn’t offer a heated steering wheel.

The Terrain’s optional dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Outlander Sport doesn’t offer dual zone air conditioning.

Both the Terrain and the Outlander Sport 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 Outlander Sport doesn’t offer rear air conditioning vents, only heat vents.

To keep a safe, consistent following distance, the Terrain has a standard Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Outlander Sport doesn’t offer an adaptive cruise control.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the GMC Terrain offers an optional wireless phone charging system (Qi) in the front center console. The Outlander Sport doesn’t offer wireless personal charging.

Recommendations

The GMC Terrain outsold the Mitsubishi Outlander Sport by almost five to one during 2023.
