The BMW X3 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 Acadia doesn’t offer a front passenger side knee airbag.

The X3 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 Acadia doesn’t offer a whiplash protection system.

The X3 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 Acadia 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 X3 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 Acadia doesn’t offer backup collision prevention brakes.

The X3’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 Acadia doesn’t offer a driver alert monitor.

Both the X3 and the Acadia have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

The BMW X3 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Acadia is not even a standard “Top Safety Pick” for 2024.

Warranty

The X3 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Acadia’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The X3’s corrosion warranty is 6 years and unlimited miles longer than the Acadia’s (12/unlimited vs. 6/100,000).

BMW pays for scheduled maintenance on the X3 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 Acadia.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the X3’s reliability 29 points higher than the Acadia.

J.D. Power and Associates’ 2022 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 vehicles. J.D. Power ranks BMW above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, GMC is rated lower.

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 X3 s/xDrive30i’s standard 2.0 turbo 4-cylinder produces 20 more horsepower (248 vs. 228) than the Acadia’s standard 2.0 turbo 4-cylinder. The X3 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 72 more horsepower (382 vs. 310) and 98 lbs.-ft. more torque (369 vs. 271) than the Acadia’s optional 3.6 DOHC V6.

Fuel Economy and Range

On the EPA test cycle the X3 gets better mileage than the Acadia:

			MPG
X3
	RWD	2.0 turbo 4-cyl.	23 city/29 hwy
	AWD	2.0 turbo 4-cyl.	21 city/28 hwy
		3.0 turbo 6-cyl. Hybrid	21 city/26 hwy
Acadia
	FWD	3.6 DOHC V6	19 city/27 hwy
		2.0 turbo 4-cyl.	22 city/29 hwy
	AWD	3.6 DOHC V6	19 city/26 hwy

Regardless of its engine, regenerative brakes improve the X3’s fuel efficiency by converting inertia back into energy instead of wasting it. GMC only offers a regenerative brake system on the Acadia 2.0 Turbo.

The X3 has a standard locking fuel door with a power remote release convenient to the driver. The fuel filler door is not lockable on the Acadia. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Transmission

The X3 M40i’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Acadia doesn’t offer launch control.

Brakes and Stopping

For better stopping power the X3’s brake rotors are larger than those on the Acadia:

	X3	X3 M40i	Acadia
Front Rotors	13 inches	13.7 inches	12.6 inches
Rear Rotors	13 inches	13.5 inches	12.4 inches

The X3 stops much shorter than the Acadia:

	X3	Acadia
70 to 0 MPH	158 feet	173 feet	Car and Driver
60 to 0 MPH	112 feet	126 feet	Motor Trend

Tires and Wheels

For better traction, the X3 has larger standard tires than the Acadia (245/50R19 vs. 235/65R18).

The X3’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 Acadia SLE/SLT’s standard 65 series tires. The X3’s optional 245/40R21 front and 275/35R21 rear tires have a lower 40 series front and 35 series rear profile than the Acadia’s optional 55 series tires.

For better ride, handling and brake cooling the X3 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Acadia AT4. The X3’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Acadia.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X3 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Acadia doesn’t offer run-flat tires.

Suspension and Handling

The X3’s front to rear weight distribution is more even (49% to 51%) than the Acadia’s (56.5% to 43.5%). This gives the X3 more stable handling and braking.

The X3 M40i xDrive handles at .88 G’s, while the Acadia Denali AWD pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The X3 M40i xDrive executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the Acadia SLT AWD (25.9 seconds @ .72 average G’s vs. 26.9 seconds @ .67 average G’s).

For greater off-road capability the X3 has a greater minimum ground clearance than the Acadia (8 vs. 7.2 inches), allowing the X3 to travel over rougher terrain without being stopped or damaged.

Chassis

The X3 is 7.5 inches shorter than the Acadia, making the X3 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The X3 has a much larger cargo volume than the Acadia with its rear seat up (28.7 vs. 12.8 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the X3 easier. The X3’s cargo hatch lift-over height is 28.5 inches, while the Acadia’s liftover is 32 inches.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the X3. The Acadia doesn’t offer locking storage for small valuables.

Towing

The X3’s standard towing capacity is much higher than the Acadia’s (4400 vs. 1000 pounds).

Servicing Ease

The engine in the X3 is mounted longitudinally (North-South), instead of sideways, as in the Acadia. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that BMW service is better than GMC. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 13% lower rating, GMC is ranked 15th.

Ergonomics

The X3’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 Acadia’s rear power window switches have to be held the entire time to open them fully. Only its driver’s window closes automatically.

If the windows are left open on the X3 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 Acadia can only operate the windows from inside the vehicle, with the ignition on.

The X3’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 Acadia’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The X3’s headlights were rated “Good” by the IIHS, while the Acadia’s headlights are rated “Marginal.”

To help drivers avoid possible obstacles, the X3 offers optional cornering lights to illuminate around corners when the turn signals are activated. The Acadia doesn’t offer cornering lights. The X3 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The X3’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Acadia doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the X3 owner. The Car Book by Jack Gillis rates the X3 with a number “5” insurance rate while the Acadia is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the X3 is less expensive to operate than the Acadia because typical repairs cost less on the X3 than the Acadia, including $33 less for front brake pads and $84 less for a timing belt/chain.

Recommendations

Consumer Reports® recommends both the BMW X3 and the GMC Acadia, based on reliability, safety and performance.
