On the EPA test cycle the G 550 gets better fuel mileage than the LX 570 (13 city/17 hwy vs. 12 city/16 hwy).

An engine control system that can shut down some of the engine’s cylinders helps improve the G-Class’ fuel efficiency. The LX 570 doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the G-Class’ 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 G-Class has 1.8 gallons more fuel capacity than the LX 570 (26.4 vs. 24.6 gallons), for longer range between fill-ups.

For better traction, the G-Class’ optional tires are larger than the largest tires available on the LX 570 (295/40R22 vs. 285/50R20).

The G-Class’ optional 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.

For better ride, handling and brake cooling the G-Class offers optional 22-inch wheels. The LX 570’s largest wheels are only 21-inches.

The Mercedes G-Class may be more efficient, handle and accelerate better because it weighs about 150 to 250 pounds less than the Lexus LX 570.

The G 550 is 10.3 inches shorter than the LX 570, making the G-Class easier to handle, maneuver and park in tight spaces.

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

To help drivers see further while navigating curves, the G-Class has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The LX 570 doesn’t offer cornering lights.

The G-Class’ power mirror controls are mounted on the door 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 G-Class offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. 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 G-Class has a standard wireless phone charging system (Qi) in the center console. Only the LX 570 Three-Row offers wireless charging and it costs extra.

The G-Class’ 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.
