Safety Comparison

For enhanced safety, the front and middle seat shoulder belts of the Mercedes GL-Class have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Lexus LX 570 doesn’t offer pretensioners for the middle seat belts.

An active infrared night vision system optional on the GL-Class helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The LX 570 doesn’t offer a night vision system.

The GL-Class’ 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 GL-Class 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 GL-Class and the LX 570 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height-adjustable front shoulder belts, four-wheel antilock brakes, all-wheel drive, traction control, electronic stability systems to prevent skidding, collision warning systems, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

Warranty Comparison

There are over 58 percent more Mercedes dealers than there are Lexus dealers, which makes it much easier should you ever need service under the GL-Class’ warranty.

Reliability Comparison

J.D. Power and Associates rated the GL-Class second among large premium suvs in their 2015 Initial Quality Study. The LX 570 isn’t in the top three in its category.

Engine Comparison

The GL550’s standard 4.7 turbo V8 produces 46 more horsepower (429 vs. 383) and 113 lbs.-ft. more torque (516 vs. 403) than the LX 570’s 5.7 DOHC V8. The GL63 AMG’s standard 5.5 turbo V8 produces 167 more horsepower (550 vs. 383) and 157 lbs.-ft. more torque (560 vs. 403) than the LX 570’s 5.7 DOHC V8.

The GL-Class’ 3.0 turbo V6 diesel produces 52 lbs.-ft. more torque (455 vs. 403) than the LX 570’s 5.7 DOHC V8.

As tested in Motor Trend the GL450 3.0 turbo V6 is faster than the Lexus LX 570:

Fuel Economy and Range Comparison

On the EPA test cycle the GL350 BlueTEC gets better fuel mileage than the LX 570 (19 city/26 hwy vs. 13 city/18 hwy).

On the EPA test cycle the GL450 V6 gets better fuel mileage than the LX 570 with its standard V8 (17 city/21 hwy vs. 13 city/18 hwy).

In heavy traffic or at stoplights the GL-Class GL450/GL63 AMG’s 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.

The GL-Class has 1.8 gallons more fuel capacity than the LX 570 (26.4 vs. 24.6 gallons), for longer range between fill-ups.

Brakes and Stopping Comparison

For better stopping power the GL63 AMG’s brake rotors are larger than those on the LX 570:

13.9 inches

Tires and Wheels Comparison

For better traction, the GL550/GL63 AMG’s tires are larger than the largest tires available on the LX 570 (295/40R21 vs. 285/50R20).

The GL550/GL63 AMG’s tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the LX 570’s 50 series tires.

Suspension and Handling Comparison

For superior ride and handling, the Mercedes GL-Class 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 GL-Class offers 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 LX 570 doesn’t offer an active sway bar system.

The front and rear suspension of the GL-Class 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 GL-Class’ 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 GL-Class’ wheelbase is 8.9 inches longer than on the LX 570 (121.1 inches vs. 112.2 inches).

For better handling and stability, the average track (width between the wheels) on the GL-Class is .5 inches wider in the front and 1.4 inches wider in the rear than the average track on the LX 570.

The GL63 AMG handles at .84 G’s, while the LX 570 pulls only .73 G’s of cornering force in a Car and Driver skidpad test.

The GL63 AMG executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the LX 570 (26.8 seconds @ .69 average G’s vs. 27.9 seconds @ .66 average G’s).

For greater off-road capability the GL-Class has a 2 inches greater minimum ground clearance than the LX 570 (10.9 vs. 8.9 inches), allowing the GL-Class to travel over rougher terrain without being stopped or damaged. The GL-Class’ minimum ground clearance is 3.1 inches higher than on the LX 570 (12 vs. 8.9 inches).

Chassis Comparison

The Mercedes GL-Class may be more efficient, handle and accelerate better because it weighs about 250 to 650 pounds less than the Lexus LX 570.

Unibody construction makes the GL-Class’ chassis much stiffer, which contributes to better handling, and enables softer springs to be used for a better ride. Unibody construction’s stiffness also contributes to better durability and less body squeaks and rattles. The LX 570 doesn’t use unibody construction, but a body-on-frame design.

Passenger Space Comparison

The GL-Class has 2.9 inches more front headroom, 1.1 inches more rear headroom, 2.5 inches more rear legroom, 3.1 inches more third row headroom and 6.7 inches more third row legroom than the LX 570.

Cargo Capacity Comparison

The GL-Class’ cargo area provides more volume than the LX 570.

The GL-Class’ cargo area is larger than the LX 570’s in every dimension:

GL-Class

LX 570

Length to seat (3rd/2nd/1st)

19.7”/52.4”/84.1”

15.6”/46”/66.8”

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

The GL-Class’ liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The LX 570’s tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

Ergonomics Comparison

Unlike the driver-only memory system in the LX 570, the GL-Class offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The power windows standard on both the GL-Class and the LX 570 have locks to prevent small children from operating them. When the lock on the GL-Class 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.

The GL-Class’ power mirror controls are mounted on the armrest for easy access. The LX 570’s power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

The GL-Class’ optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The LX 570 doesn’t offer an automated parking system.

Recommendations Comparison

The Mercedes GL-Class won two awards in Kiplinger’s 2015 car issue. The Lexus LX 570 didn't win any award.

Motor Trend performed a comparison test in its July 2015 issue and they ranked the Mercedes GL450 higher than the Lexus LX 570.

Motor Trend selected the GL-Class as their 2013 Sport Utility of the Year. The LX 570 has never been chosen.

The Mercedes GL-Class outsold the Lexus LX 570 by almost eight to one during the 2015 model year.
