The X4’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.

The BMW X4 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 X4 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Terrain doesn’t offer a whiplash protection system.

The X4 has a standard PostCrash iBrake, 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.

Over 200 people are killed each year when backed over by motor vehicles. The X4 offers an optional Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Terrain doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X4. But it costs extra on the Terrain.

The X4 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. A system to reveal vehicles in the Terrain’s blind spot costs extra.

To help make backing out of a parking space safer, the X4 has standard Cross Traffic Warning, helping the driver avoid collisions. GMC charges extra for Rear Cross Traffic Alert on the Terrain.

The X4’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Terrain doesn’t offer a driver alert monitor.

Both the X4 and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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 and available around view monitors.

The BMW X4 weighs 483 to 984 pounds more than the GMC Terrain. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

The X4 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 X4’s corrosion warranty is 6 years and unlimited miles longer than the Terrain’s (12/unlimited vs. 6/100,000).

BMW pays for scheduled maintenance on the X4 for 3 years and 36,000 miles. BMW will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. GMC only pays for the first scheduled maintenance visit on the Terrain.

Reliability

J.D. Power and Associates rated the X4 first among compact premium suvs in their 2024 Initial Quality Study. The Terrain was rated second in its category.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than GMC With 16 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks BMW higher than GMC.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that BMW vehicles are more reliable than GMC vehicles. Consumer Reports ranks BMW 15 places higher in reliability than GMC.

Engine

The X4 xDrive30i’s standard 2.0 turbo 4-cylinder produces 73 more horsepower (248 vs. 175) and 55 lbs.-ft. more torque (258 vs. 203) than the Terrain’s 1.5 turbo 4-cylinder. The X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 207 more horsepower (382 vs. 175) and 166 lbs.-ft. more torque (369 vs. 203) than the Terrain’s 1.5 turbo 4-cylinder.

Fuel Economy and Range

Regenerative brakes improve the X4’s fuel efficiency by converting inertia back into energy instead of wasting it. The Terrain doesn’t offer a regenerative braking system.

The X4 has 2.3 gallons more fuel capacity than the Terrain FWD’s standard fuel tank (17.2 vs. 14.9 gallons), for longer range between fill-ups. The X4 has 1.6 gallons more fuel capacity than the Terrain AWD’s standard fuel tank (17.2 vs. 15.6 gallons).

The X4 has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Terrain. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Brakes and Stopping

For better stopping power the X4’s brake rotors are larger than those on the Terrain:

	X4 xDrive30i	X4 M40i	Terrain
Front Rotors	13 inches	13.7 inches	11.8 inches
Rear Rotors	13 inches	13.6 inches	11.3 inches

The X4’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.

Tires and Wheels

For better traction, the X4 has larger standard tires than the Terrain (245/50R19 vs. 225/65R17). The X4’s optional tires are larger than the largest tires available on the Terrain (F:245/45R20 & R:275/40R20 vs. 235/50R19).

The X4’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Terrain SLE/AT4’s standard 65 series tires. The X4’s optional 245/40R21 front and 275/35R21 rear tires have a lower 40 series front and 35 series rear profile than the Terrain’s optional 50 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Terrain SLE/AT4. The X4’s optional 21-inch wheels are larger than the 19-inch wheels optional on the Terrain.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X4 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Terrain doesn’t offer run-flat tires.

Suspension and Handling

The X4 has standard front and rear stabilizer bars, which help keep the X4 flat and controlled during cornering. The Terrain’s suspension doesn’t offer a rear stabilizer bar.

The X4 offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Terrain’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the X4’s wheelbase is 5.5 inches longer than on the Terrain (112.8 inches vs. 107.3 inches).

For better handling and stability, the average track (width between the wheels) on the X4 is 1.2 inches wider in the front and 2.7 inches wider in the rear than the track on the Terrain.

The X4 M40i handles at .89 G’s, while the Terrain Denali AWD pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the Terrain Denali AWD (25.6 seconds @ .73 average G’s vs. 27.5 seconds @ .64 average G’s).

For greater off-road capability the X4 has a 1.1 inches greater minimum ground clearance than the Terrain SLE (8 vs. 6.9 inches), allowing the X4 to travel over rougher terrain without being stopped or damaged. The X4’s minimum ground clearance is .1 inch higher than on the Terrain SLT/AT4/Denali (8 vs. 7.9 inches).

Passenger Space

The X4 has .3 inches more front shoulder room and .4 inches more rear shoulder room than the Terrain.

Cargo Capacity

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the X4. The Terrain doesn’t offer locking storage for small valuables.

Servicing Ease

The X4 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 engine in the X4 is mounted longitudinally (North-South), instead of sideways, as in the Terrain. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

The X4’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 X4 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 or with the driver’s door power window switch. The driver of the Terrain can only close the windows from inside the vehicle, with the ignition on.

The X4’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 manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the X4 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 X4 has standard cornering lights to illuminate around corners when the turn signals are activated. The Terrain doesn’t offer cornering lights. The X4 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The X4’s standard 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 has an automatic rear view mirror, but its side mirrors don’t dim.

Both the BMW X4 and GMC Terrain offer exterior mirrors that can be folded to provide convenience. The X4 features standard 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 X4 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.

The BMW X4 has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Homelink® is only available on the Terrain SLT/AT4/Denali.

The X4’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Terrain Denali’s automatic parking system requires operating the brakes and transmission to safely park.

Recommendations

J.D. Power and Associates rated the X4 first among compact premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Terrain isn’t in the top three in its category.
