For better protection of the passenger compartment, the GLS uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The GX460 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the GLS and the GX460 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, 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 lane departure warning systems.

The Mercedes GLS weighs 503 to 571 pounds more than the Lexus GX460. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

On the EPA test cycle the GLS 450 gets better fuel mileage than the GX460 (19 city/23 hwy vs. 15 city/19 hwy).

On the EPA test cycle the GLS 450 gets better fuel mileage than the GX460 (19 city/23 hwy vs. 15 city/19 hwy).

Regenerative brakes improve the GLS’ fuel efficiency by converting inertia back into energy instead of wasting it. The GX460 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the GLS’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The GX460 doesn’t offer an automatic engine start/stop system.

The GLS’ tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the GX460’s standard 60 series tires.

For better ride, handling and brake cooling the GLS has standard 19-inch wheels. Only 18-inch wheels are available on the GX460. The GLS offers optional 23-inch wheels.

For superior ride and handling, the Mercedes GLS has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Lexus GX460 has a solid rear axle, with a non-independent rear suspension.

The front and rear suspension of the GLS uses air springs for a smoother, controlled ride than the GX460, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The GLS offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Lexus doesn’t offer an active suspension on the GX460.

The GLS’ drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The GX460 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLS’ wheelbase is 13.6 inches longer than on the GX460 (123.4 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the GLS is 3.3 inches wider in the front and 4.2 inches wider in the rear than on the GX460.

For better maneuverability, the GLS’ turning circle is 1.7 feet tighter than the GX460’s (39.4 feet vs. 41.1 feet).

For greater off-road capability the GLS has a 2 inches greater minimum ground clearance than the GX460 (10.1 vs. 8.1 inches), allowing the GLS to travel over rougher terrain without being stopped or damaged. The GLS Off-Road Package’s minimum ground clearance is 3.2 inches higher than on the GX460 (11.3 vs. 8.1 inches).

Unibody construction lowers the GLS’ center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The GX460 uses body-on-frame design instead.

The design of the Mercedes GLS amounts to more than styling. The GLS has an aerodynamic coefficient of drag of .32 Cd. That is lower than the GX460 (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLS get better fuel mileage.

Pressing a switch automatically lowers or raises the GLS’ second and third row seats, to make changing between cargo and passengers easier. The GX460 doesn’t offer automatic folding second row seats.

To make loading and unloading groceries and cargo easier when your hands are full, the GLS’ power cargo door can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The GX460 doesn’t offer a power or hands-free opening cargo door.

Unlike the driver-only memory system in the GX460, the GLS has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLS offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GX460 doesn’t offer a heads-up display.

The GLS’ power parking brake sets with one touch and releases with one touch or automatically. The GX460’s parking brake has to released manually.

The GLS’ 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 GX460’s standard manually variable intermittent wipers have to be constantly adjusted.

The GLS’ power mirror controls are mounted on the armrest for easy access. The GX460’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

The GLS has standard heated front and optional heated second and third row seats, which keep the driver and passengers extremely comfortable in the winter. Lexus doesn’t offer heated seats in the third row of the GX460.

Optional air conditioned the front and second row seats keep the GLS’ passengers comfortable and take the sting out of hot leather in summer. The GX460 doesn’t offer air-conditioned seats for the second row.

The GLS offers optional massaging front and second row seats, which keep the driver and middle row passengers. Massaging seats aren’t available in the GX460.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLS has a standard wireless phone charging system (Qi) in the center console and for the rear passengers. The GX460 doesn’t offer wireless personal charging.

The GLS’ Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The GX460 doesn’t offer an automated parking system.
