Compare the2024 BMW X4VS 2023 Buick Envision

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 Envision 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 Envision doesn’t offer a front passenger side knee airbag.

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 Envision 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 Envision 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 X4. But it costs extra on the Envision.

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 Envision doesn’t offer a driver alert monitor.

Both the X4 and the Envision have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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 X4 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Envision’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 Envision’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. Buick doesn’t pay scheduled maintenance for the Envision.

J.D. Power and Associates rated the X4 second among compact premium suvs in their 2023 Initial Quality Study. The Envision isn’t in the top three in its category.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that BMW vehicles are more reliable than Buick vehicles. Consumer Reports ranks BMW third in overall reliability. Buick is ranked 11th.

The X4 xDrive30i’s standard 2.0 turbo 4-cylinder produces 20 more horsepower (248 vs. 228) than the Envision’s 2.0 turbo 4-cylinder. The X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 154 more horsepower (382 vs. 228) and 111 lbs.-ft. more torque (369 vs. 258) than the Envision’s 2.0 turbo 4-cylinder.

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

The X4 has 1.3 gallons more fuel capacity than the Envision FWD’s standard fuel tank (17.2 vs. 15.9 gallons), for longer range between fill-ups. The X4 has 1.1 gallons more fuel capacity than the Envision AWD’s standard fuel tank (17.2 vs. 16.1 gallons).

The X4 has a standard locking fuel door with a power remote release convenient to the driver. The fuel filler door is not lockable on the Envision. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

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

For better traction, the X4 has larger standard tires than the Envision (245/50R19 vs. 235/60R18).

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 Envision’s standard 60 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 Envision’s optional 45 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Envision. The X4’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Envision.

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 Envision doesn’t offer run-flat tires.

The X4 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 Envision doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the X4’s wheelbase is 3.4 inches longer than on the Envision (112.8 inches vs. 109.4 inches).

For better handling and stability, the average track (width between the wheels) on the X4 is .2 inches wider in the front and 1.9 inches wider in the rear than the track on the Envision.

The front grille of the X4 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Envision doesn’t offer active grille shutters.

The X4 has .7 inches more front headroom, .3 inches more front legroom, .8 inches more front shoulder room and .1 inches more rear shoulder room than the Envision.

For enhanced passenger comfort on long trips the X4’s rear seats recline. The Envision’s rear seats don’t recline.

Pulling a handle automatically lowers the X4’s rear seats, to make changing between passengers and cargo easier. The Envision doesn’t offer automatic folding seats.

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

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

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 Envision’s rear power window switches have to be held the entire time to close them fully.

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 Envision 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 Envision’s standard manually variable intermittent wipers have to be constantly adjusted.

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 Envision.

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 Envision isn’t in the top three in its category.
