Safety

For enhanced safety, the front and middle seat shoulder belts of the Lexus LX 570 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.

The LX 570 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.

To help make backing safer, the LX 570’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLS doesn’t offer a cross-path warning system.

Both the LX 570 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 and rearview cameras.

Warranty

Lexus’ powertrain warranty covers the LX 570 2 years and 20,000 miles longer than Mercedes covers the GLS. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the GLS ends after only 4 years or 50,000 miles.

The LX 570’s corrosion warranty is 1 year longer than the GLS’ (6 vs. 5 years).

J.D. Power ranks Lexus first in reliability, above the industry average. With 28 more problems per 100 vehicles, Mercedes is ranked 13th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Lexus vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Lexus first in reliability. Mercedes is ranked 17th.

Engine

The LX 570’s 5.7 DOHC V8 produces 21 more horsepower (383 vs. 362) and 34 lbs.-ft. more torque (403 vs. 369) than the GLS 450’s standard 3.0 turbo V6.

Motor Trend

Tires and Wheels

The LX 570’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the GLS’ standard 55 series tires.

For better ride, handling and brake cooling the LX 570 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the GLS.

Suspension and Handling

For better maneuverability, the LX 570’s turning circle is 2 feet tighter than the GLS’ (38.7 feet vs. 40.7 feet).

For greater off-road capability the LX 570 has a 1.1 inches greater minimum ground clearance than the AMG GLS 63 (8.9 vs. 7.8 inches), allowing the LX 570 to travel over rougher terrain without being stopped or damaged.

Chassis

The design of the Lexus LX 570 amounts to more than styling. The LX 570 has an aerodynamic coefficient of drag of .35 Cd. That is lower than the GLS (.37 to .38). A more efficient exterior helps keep the interior quieter and helps the LX 570 get better fuel mileage.

Passenger Space

The LX 570 has standard seating for 8 passengers; the GLS can only carry 7.

For enhanced passenger comfort on long trips the LX 570’s middle and third row seats recline. The GLS’ third row seats don’t recline.

Cargo Capacity

The LX 570’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The GLS’ rear cargo window doesn’t open.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Mercedes. J.D. Power ranks Lexus second in service department satisfaction. With a 11% lower rating, Mercedes is ranked fifth.

Ergonomics

The LX 570’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the GLS.

The LX 570’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The GLS does not have an oil pressure gauge.

The LX 570 offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GLS doesn’t offer a heads-up display.

To improve rear visibility by keeping the rear window clear, the LX 570 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.

Optional air conditioned the front and second row seats keep the LX 570’s passengers comfortable and take the sting out of hot leather in summer. The GLS doesn’t offer air-conditioned seats for the second row.

The LX 570 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 GLS.

Economic Advantages

The LX 570 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the LX 570 will retain 50.48% of its original price after five years, while the GLS only retains 43.11% to 44.05%.
