Compare the2025 Audi Q3VS 2025 GMC Terrain

The Q3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Terrain doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Audi Q3 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The GMC Terrain doesn’t offer height-adjustable seat belts.

Both the Q3 and Terrain have child safety locks to prevent children from opening the rear doors. The Q3 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Terrain’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Audi Q3 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Terrain doesn’t offer knee airbags.

The Q3 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Terrain 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q3. But it costs extra on the Terrain.

Both the Q3 and the Terrain 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, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The Q3 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Terrain’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The Q3’s corrosion warranty is 6 years and unlimited miles longer than the Terrain’s (12/unlimited vs. 6/100,000).

The Audi Q3’s engines use a cast iron block for durability, while the Terrain’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

To reliably power the ignition and other systems and to recharge the battery, the Q3 has a standard 140-amp alternator. The Terrain’s 130-amp alternator isn’t as powerful.

J.D. Power and Associates rated the Q3 second among small premium suvs in their 2024 Initial Quality Study. The Terrain isn’t in the top three in its category.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Audi vehicles are more reliable than GMC vehicles. Consumer Reports ranks Audi 5 places higher in reliability than GMC.

The Q3 40 TFSI’s standard 2.0 turbo 4-cylinder produces 9 more horsepower (184 vs. 175) and 37 lbs.-ft. more torque (221 vs. 184) than the Terrain FWD’s standard 1.5 turbo 4-cylinder. The Q3 40 TFSI’s 2.0 turbo 4-cylinder produces 9 more horsepower (184 vs. 175) and 18 lbs.-ft. more torque (221 vs. 203) than the Terrain AWD’s standard 1.5 turbo 4-cylinder. The Q3 45 TFSI’s standard 2.0 turbo 4-cylinder produces 53 more horsepower (228 vs. 175) and 48 lbs.-ft. more torque (251 vs. 203) than the Terrain AWD’s standard 1.5 turbo 4-cylinder.

The Q3 has 1.1 gallons more fuel capacity than the Terrain FWD’s standard fuel tank (15.9 vs. 14.8 gallons), for longer range between fill-ups.

For better stopping power the Q3’s brake rotors are larger than those on the Terrain:

The Q3’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Terrain are solid, not vented.

For better traction, the Q3’s optional tires are larger than the largest tires available on the Terrain (255/45R19 vs. 235/65R17).

The Q3’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 Terrain’s standard 65 series tires. The Q3’s optional tires have a lower 40 series profile than the Terrain’s optional 55 series tires.

For better ride, handling and brake cooling the Q3 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Terrain. The Q3’s optional 20-inch wheels are larger than the 19-inch wheels optional on the Terrain.

The Q3 has standard front and rear stabilizer bars, which help keep the Q3 flat and controlled during cornering. The Terrain’s suspension doesn’t offer a rear stabilizer bar.

The Q3 has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Terrain doesn’t offer variable-assist power steering.

The Q3 is 4.4 inches shorter than the Terrain, making the Q3 easier to handle, maneuver and park in tight spaces.

For enhanced passenger comfort on long trips the Q3’s rear seats recline. The Terrain’s rear seats don’t recline.

A standard locking glovebox keeps your small valuables safer in the Q3. The Terrain doesn’t offer locking storage for small valuables.

The Q3’s standard towing capacity is much higher than the Terrain’s (1500 vs. 800 pounds).

The Q3 uses gas struts to support the hood for easier service access. The Terrain 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.

The Q3’s front and rear power windows all open or close 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 Terrain’s passenger windows don’t close automatically.

If the windows are left open on the Q3 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Terrain can only close the windows from inside the vehicle, with the ignition on.

The Q3’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Terrain’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the Q3 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Terrain doesn’t offer heated windshield washer nozzles.

To help drivers avoid possible obstacles, the Q3 Premium Plus has standard cornering lights to illuminate around corners when the turn signals are activated. The Terrain doesn’t offer cornering lights.

The Q3’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Terrain offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the Audi Q3 and GMC Terrain offer exterior mirrors that can be folded to provide convenience. The Q3 offers optional power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the Terrain’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The Q3 has a standard 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. Dual zone air conditioning costs extra on the Terrain.
