Compare the2024 BMW X4VS 2023 Mercedes GLE

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 GLE 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 GLE 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 GLE 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 GLE doesn’t offer automatic braking for stationary objects directly to the rear.

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

The X4’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the GLE.

Both the X4 and the GLE 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The X4’s corrosion warranty is 7 years longer than the GLE’s (12 vs. 5 years).

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. Mercedes doesn’t pay scheduled maintenance for the GLE.

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 X4’s reliability 27 points higher than the GLE.

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

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Mercedes vehicles. With 9 fewer problems per 100 vehicles, JD Power ranks BMW higher than Mercedes.

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 Mercedes 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, Mercedes is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that BMW vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks BMW third in overall reliability. Mercedes is ranked 24th.

On the EPA test cycle the X4 gets better mileage than the GLE:

Regardless of its engine, regenerative brakes improve the X4’s fuel efficiency by converting inertia back into energy instead of wasting it. Mercedes only offers a regenerative brake system on the GLE 450/580.

The X4’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the GLE 350 are solid, not vented.

The X4 stops much shorter than the GLE:

The X4’s optional 275/35R21 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the GLE 450’s optional 40 series tires.

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 GLE doesn’t offer run-flat tires.

The X4’s front to rear weight distribution is more even (49.2% to 50.8%) than the GLE’s (53.5% to 46.5%). This gives the X4 more stable handling and braking.

The X4 M40i handles at .89 G’s, while the GLE 350 4MATIC pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver 2.6 seconds quicker than the GLE 350 4MATIC (25.6 seconds @ .73 average G’s vs. 28.2 seconds @ .62 average G’s).

For greater off-road capability the X4 has a greater minimum ground clearance than the GLE (8 vs. 7.9 inches), allowing the X4 to travel over rougher terrain without being stopped or damaged.

The BMW X4 may be more efficient, handle and accelerate better because it weighs about 450 to 900 pounds less than the Mercedes GLE.

The X4 is 6.7 inches shorter than the GLE, making the X4 easier to handle, maneuver and park in tight spaces.

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 GLE doesn’t offer active grille shutters.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Mercedes. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 17% lower rating, Mercedes is ranked 18th.

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