Compare the2023 Lexus GXVS 2022 Mercedes GLS

For enhanced safety, the front and middle seat shoulder belts of the Lexus GX 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 Mercedes GLS doesn’t offer height-adjustable middle seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the GX are reminded to check the back seat if they opened the rear door before starting out. The GLS doesn’t offer a back seat reminder.

The Lexus GX 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 GLS doesn’t offer a front passenger side knee airbag.

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

The GX’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 GLS.

Both the GX and the GLS have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, 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 GX stops shorter than the GLS:

The Lexus GX’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Mercedes GLS only has 5 wheel lugs per wheel.

The GX has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the GLS; it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

The GX has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The GLS doesn’t offer an active sway bar system.

The Lexus GX may be more efficient, handle and accelerate better because it weighs about 350 to 900 pounds less than the Mercedes GLS.

The GX is 1 foot shorter than the GLS 450, making the GX easier to handle, maneuver and park in tight spaces.

The GX is 5.7 inches narrower than the GLS, making the GX easier to handle and maneuver in traffic.

The GX has 1.4 inches more front legroom, .2 inches more rear headroom and 4.2 inches more third row shoulder room than the GLS.

For enhanced passenger comfort on long trips the GX’s middle seats and third row seats (except Base/Black Line Edition) recline. The GLS’ third row seats don’t recline.

The GX’s cargo area provides more volume than the GLS.

The GX’s rear cargo window opens separately from the rest of the right swing out door to allow quicker loading of small packages. The GLS’ rear cargo window doesn’t open.

A Trailer Sway Control is standard on the GX, using the Vehicle Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. A trailer sway program costs extra on the GLS.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Mercedes. J.D. Power ranks Lexus first in service department satisfaction. With a 48% lower rating, Mercedes is ranked 18th.

To improve rear visibility by keeping the rear window clear, the GX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLS only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the GX’s headlight performance “Very Good,” a higher rating than the GLS’ headlights, which were rated “Good.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The GX offers available headlight washers to keep headlight output high. The GLS doesn’t offer headlight washers.
