The GLS’ 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 LX 570 doesn’t offer a driver alert monitor.

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 LX 570 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the GLS and the LX 570 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, around view monitors, rear cross-path warning and available lane departure warning systems.

There are over 59 percent more Mercedes dealers than there are Lexus dealers, which makes it much easier should you ever need service under the GLS’ warranty.

On the EPA test cycle the GLS 450 gets better fuel mileage than the LX 570 (19 city/23 hwy vs. 12 city/16 hwy).

Regenerative brakes improve the GLS’ fuel efficiency by converting inertia back into energy instead of wasting it. The LX 570 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 LX 570 doesn’t offer an automatic engine start/stop system.

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 LX 570 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 LX 570, 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 LX 570.

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 LX 570 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLS’ wheelbase is 11.2 inches longer than on the LX 570 (123.4 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the GLS is .8 inches wider in the front and 1.8 inches wider in the rear than the average track on the LX 570.

For greater off-road capability the GLS has a 1.2 inches greater minimum ground clearance than the LX 570 (10.1 vs. 8.9 inches), allowing the GLS to travel over rougher terrain without being stopped or damaged. The GLS Off-Road Package’s minimum ground clearance is 2.4 inches higher than on the LX 570 (11.3 vs. 8.9 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 LX 570 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 LX 570 (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLS get better fuel mileage.

The GLS has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly. The LX 570 doesn’t offer seats that fold into the floor.

Pressing a switch automatically lowers or raises the GLS’ second and third row seats, to make changing between cargo and passengers easier. The LX 570 doesn’t offer automatic folding second row seats.

To make loading groceries and cargo easier when your hands are full, the GLS’ cargo door can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The LX 570 doesn’t offer a hands-free gesture to open its tailgate, forcing you to put cargo down if your hands are full.

The power windows standard on both the GLS and the LX 570 have locks to prevent small children from operating them. When the lock on the GLS is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The LX 570 prevents the driver from operating the other windows just as it does the other passengers.

To help drivers avoid possible obstacles, the GLS has standard cornering lights to illuminate around corners when the turn signals are activated. The LX 570 doesn’t offer cornering lights. The GLS also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

Manual rear side window sunshades are available in the GLS to help block heat and glare for the rear passengers. The LX 570 doesn’t offer rear side window sunshades.

The GLS’ power mirror controls are mounted on the armrest for easy access. The LX 570’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 LX 570.

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 LX 570.

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 one for the rear passengers. Only the LX 570 Three-Row offers wireless charging and it costs extra.

The GLS’ Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The LX 570 doesn’t offer an automated parking system.
